The next North West Rolling Road Day will take place at Dyno Demon on Saturday 11th October 2008.

Cost will be £40 per car and for that you get 3 Power Runs and 2 colour graphs showing AFR / Torque / BHP at wheel and BHP at Fly.

This is for standard or modded cars - everyone welcome!

Have a look at previous threads for how professional these guys are.

We need an absolute minimum of 10 cars for this and you've all now got 3 months notice so get those jobs done and get yourselves along to this.

Can't put myself as a definate, so much could go wrong before then and would also need to get the car mapped! But hopefully will make it

i would like to come but its too far away

Guys.

Although aberdeen is far away for some of you guys, the dastek rollers plus matty working at Wallace Performance make it such a good deal!!



So would it be an idea to combine at aberdeen or is it just too far?

Ross

Ross, its 6 hours away from my house according to google maps and I am probably one of the closest out of the North West guys!

Ah well, thought it might be an idea!!

I may come down this time.

Ross

I'll be there

would be good if there was somewhere in between!

Count me in.Hoping to have the gtech set up by then,
and ross get down here, would be good to see you again!

Count me in lol!

its about a 3 hour drive for me..

Going for my hat trick now - but hopefully without the 1.7/1.8 boost spike! Gives me time to get my motor sorted & back to standard horseys hopefully!

Hey I am interested in this. AFAIK the car is standard so expecting 220 ish

Welcome Jack, you're down as number 12.

With just over a month to go, Eldinho and CoupeDave - any updates yet?

the chances of me coming to this are less than Welformed getting beat by a Robin Reliant!

Ah that happens every week, he just doesn't like to talk about it!

No worries Mark.

I think I'll make it, for the crack partly because I have had it done but I would like to compare, and might get a new turbo.

I may pop along, just to say hi to everyone, but won't be going on the rollers.

I've done nothing new to my car and am happy with the previous RR results, so no point going on it

Just realised that I am going to see Steve Coogan's live show the night before in Blackburn , and will be staying with my brother near Manchester on Saturday, so I might have to be downgraded to a maybe for this session - annoying really as I could do with a run on the RR to see if I'm back at standard now. Mad boost problem cured - dodgy actuator now replaced! Won't discount this meeting at the mo, but realistically I might not be able to come until the next session in the Winter ....

Congrats on the nuptials too Craig!

Cheers matey.

Right guys and girls, less than 2 weeks away now so can I please have some confirmations posted up?

I'll be there!

Might have to downgrade my status to 'maybe' because of boost controller issues. My Greddy has blown up, i have a prv but theres no point R/R it without it at its proper spec.
Apologies for any inconvinience.

i might have a look down if jeff is going.

is it worth posting a reminder/link of this rolling road day in coup related chat incase any newbies have missed it !?

we need more coops to run for this to go ahead !!

and i need my fuelling checked at the bargin rate

Hi. Well, I ordered a turbo today and have a ramp reserved for next Tuesday/Wednesday. Stuff starting to arrive, walbro, pads but no disks yet.
Just going for the GTiR straight swap the other alternatives looked a bit too complicated to fit.
Turbo should arrive on Tuesday at the latest.
I'm going to wait till to morrow to say a yes though.

I've spoken to Dyno Demon this morning with the intention of cancelling this due to insufficient numbers. I won't be running myself as I haven't had chance to sort my coop due to my recent wedding.

Dyno Demon have been kind enough to hold the date open for us with a slight ammendment to prices. If less than 10 cars, then the price goes to £45. Less than 5 cars and it goes to £50.

We've been able to get these prices as we're regulars there and they're trying to look after us, which I think is very fair.

i ll make a place up ..

Hoping there will be a chance of a slight 2 minute fiddle between runs ....?

good work craig,i will still run even if we get less than 5 its still cheaper than their normal price

Hi I'll run.
Even though I haven't got everything that I need yet I am confident it will arrive.

I still fancy this - I'm a step closer than I was, as I've now replaced my coilpacks and wiring loom to the coils (all the extra load had cooked the cables )

I just need to road-test it to see if it will handle 2 bar again without misfiring - if it does, I should be able to make it.

It would be interesting to see what the car gives on a different dyno

Would be good to see your results on this dyno Nigel as this will probably be the one I get mine ran on once its back! With quite a similar setup it would be good to compare!

Have my Greddy repaired now so i am upgrading myself to confirmed

are we having time slots again sat craig ?

Hi all had some more work done at motormech yesterday ,and new front front tyers so count me in ,looking forward to it and meeting you all.
Kev & Bev..

Yes I think so Steve. I know some of you get there first thing and stay throughout whilst some are only able to stay for a short time. Either is cool with me however my coop running will be dependant on a couple of alterations happening on the actual day so I'll keep myself as a possible and won't be taking an early time slot.

The earliest time slot will be 9.00am then in 30 minute slots thereafter.

1. MABR - POSSIBLE

TIME: ANY

2. Taffy - DECLINED (but still attending and spannering!)

3. Pebbles - CONFIRMED

TIME: ???

4. MattM - CONFIRMED

TIME: ???

5. Clay99 - CONFIRMED (Honda Type R)

6. Lucifer - CONFIRMED

7. Sprintsteve - CONFIRMED

8. mona - ???

9. Jef_uk - CONFIRMED (dependant on bits arriving )

TIME: ???

10. Bosco - CONFIRMED

TIME: 9.30am

11. Nigel - ???



EDIT: Mona and Nigel - any decisions yet?

Any chance of 9.30 to give me time to call in at the hot pork pie bakery on the industrial estate !!!

Done.

can i have 11.00 please craig

Done.

I'm still waiting for my turbo, I'll chase them tomorrow, if it will arrive in the next two days I might get it fitted.

i, give them a ring.. thought it would of been next day del.

Looking unlikely MABR due to current circumstances - but I could do with a session to see if the boost is OK now (I'm assured it is!).

I'm going to see Steve Coogan in Blackburn on the Friday & I'm not getting the reassuring noises I like from my brother that the Coupe will get left alone from local yobboe types overnight - and I'm not sure what the plan is for the next day. The Corsa might have to be used this weekend, but that is also awaiting fitment of a rear hatch spoiler towards the end of the week - that's where the Coupe comes in again!

On top of this, I have a job interview tomorrow, so my head's a bit all over the place tonight! If you need a definite answer now, then I'll have to regretfully decline for this session - but I hope I could join in if things change by the end of the week .....?

No problems matey.

I'd need to know by Friday at the latest.

OK the turbo should today so fingers crossed!

Just catching up on all this, I'm still a definite. Not sure what time slots are available but 12 o clock would be ideal, is that an option?

The earliest time slot will be 9.00am then in 30 minute slots thereafter.

1. MABR - POSSIBLE

TIME: ANY

2. Taffy - DECLINED (but still attending and spannering!)

The later time slots will be dependant on numbers attending, hence the 9.00am start.

Sorry I could not make this my manifold was cracked and I had a sized nut holding the turbo to it (Which I had to brake) didn't want to go to the trouble of putting it back together to dismantle it sorry.

Not sure if you read my reply on the other forum Sprintsteve, let me know if not.

hi flea, yes just read it before begbie shut me out !!

you have a pm

well - that was a crap result (although not entirely unexpected)

I knew I had a misfire, so wanted to use the day to see what the car was doing.

I managed a paltry 270bhp @ 1.2 bar. The car misfired at anything above 1.5 bar and just wouldn't give enough boost.

It ran lean until I reset the ECU, then it went off the scale rich as it spooled up (less than 10AFR)

Ar$e

First rolling road for me since I had all the recent work done, and very happy with the result. I've been running on low boost since the rebuild, as I wanted to establish that the car was running safe and healthy before putting it back up to it's full potential.

275bhp at just under 1.2 bar, with perfect torque curve and fuelling. The guys at Dyno Demon said that I can now safely turn the boost gauge up slightly, and so on the next run I will take a figure at 1.4 bar and see where it's at.

Very happy with the result

Time for a Fleamap then Nigel? Sounds like the same mapping problem (ahem PT ahem) that Luke's car had

Once the ECU had been reset, the fuelling was spot on, but the huge misfire was completely screwing the spoolup.

I'll be letting Flea loose on the car soon - watch this space....

I'm confused, was it rich or perfect? I assume the misfiring is due to the boost blowing out the spark still? How do other marque 'high boost heroes'(tm) get around this problem? Do they even suffer from it? I remember the Lancer forums 40-120mph board showing a few running crazy 1.7-2.5bar...



Glad to hear this though, I'm sure he'll be able to sort a lot of your ECU reset issues with a good map. It'll be good to see the results. The guys over at Track'n'road were very impressed with my map and results even asking who had done it. I have a feeling they'll be looking out for Leighton's work in future

Hi all ,this was my first at the rolling road, enjoyed the company and the experiance ,my coupe is standard and i got 227bhp realy happy that i've got a healthy engine,and i'd recommend even if you are standard, I would still go to a rolling road to check that everything is running smoothly.

Bev & Kev..

posted this on other forum, but thought stick it on here.
was another good meet glad to see you all again!

Thought i would post my graphs up,made 260.9 bhp was told fueling was fine nothing to worry about after my runs on the day, but after comments from flea and looking at other graphs on here my fueling is very wrong and way too lean!

checked my exhaust all the way through tonight for leaks which may have effected AFR reading,all is fine apart from i think the manifold is cracked i can see very small amount of exhaust gas rising past manifold cover after a run?

would this cause me to run this lean ?surely i dont need an uprated fuel pump or wiring mod for this level of tune?
put standard chip back in tonight sulking now !
will have to get my manifold sorted too.

graphs from a couple of months back at dyno demon,my mods s/s cat back ,cone filter and bailey dv.

yup, its a bit lean, but not horribly so

ideal AFR is around 11 - 11.5 - yours is 13.5, drifting towards 12 as the revs rise (which is the right direction for it to drift)

trappy - sorry, I didn't make myself clear

After the ECU reset, I ran at 2 bar.

the fuelling trace shows a pretty steady 11AFR until the turbo started to spool up, at which point, the AFR plummeted (rich). As soon as the misfire had stopped, the AFR jumped back up to 11 and stayed very close to 11 all the way to the rev limiter.

My guess is that the mad AFR ISN'T caused by the fuelling map, its the result of unburned fuel hitting the lambda as the spark is killed. However, I need to get to the bottom of why the spark is dying - is it det? Is it a dying plug? is it the advance going mad? Is it poor voltage at the coils?

Flea is going to have his work cut out, but if he can sort it (and the ECU learning issue) then it would look like he's managed to crack the control of the Motronic. I hope so, as wifey will probably baulk at a Santa letter saying "Motec and mapping"

Sorry it's taken me so long to post up on here after I'd organised the damn thing.

Nice to see everyone again including Nigel and Bosco who both must have had a fair distance to travel to get there.

A good day all round with 9 coops going on the rollers. Some disappointments but hopefully people now know the solutions needed (Nigel's got Leighton on speed-dial ).

Special thanks from me to Adam, Clayton, Matt and Joe for supplying parts / advice / spannering on my coop. After the changes, she ran 253bhp with far better fuelling. Now need to get an uprated panel filter and that'll be it until the turbo decides to let go.

Extra special thanks to Steve at Dyno Demon for only charging the 10+ cars rate - very much appreciated.

I've spoken to Steve today to arrange the next date (see seperate thread) and he informed me that they had just literally, been confirmed as the area Dastek rep.

Hey Nigel, this is a little confusing



Since the lambda detects oxygen and not fuel. I would guess the fuel would burn in the turbo using up all the oxygen, probably spitting some soot out the back.

Are these quoted numbers from a wide band sensor, as a narrow band really only tells you rich, lean or ok, with little to distinguish how lean or how rich?

cheers

Rich - its from a probe up the tailpipe on the dyno. I imagine if the fuel isn't being burnt in the cylinder, its either getting burnt somewhere after the exhaust ports or quite possibly, not being burnt at all - the clouds of smoke out the back when it misfires would suggest its not getting burnt (or at least the majority of it isn't)

What fuel can burn must be using the oxygen the rest as partially combusted smoke. makes sense. I'll guess the EGT would be pretty high if combustion is occuring outside of the cylinders.

it has been suggested that backpressure may be the issue, but I'm not convinced.

I can't understand why the car would run 2 bar of boost with no misfire at TOTB (albeit with a splash of octane booster) but now can't run 1.6 bar without causing a smoke screen of pea-soup consistency

There are two (potentially conflicting) factors

the misfire reduces (or even goes away) when I gap the plugs down to 0.6mm (from 0.8mm standard)

the misfire only started after the last remap, which coincided with the fitment of a 3.8bar FPR Prior to this, I only ran 1.6 bar max (everything else the same)

TBH, I'm not that bothered with being able to run 2 bar - its massively violent to drive and gives slightly less power (down to about 385 at PT) The torque was huge though - over 400lb-ft, which was entertaining, but tiring.

Nope, I just want to be able to run 1.6 - 1.7 bar with safety

What FPR were you running prior to this latest remap then Nigel? Surely not the standard item...

As far as I'm aware, the high boost misfiring is the same problem that Flea's car is suffering from but again he has had a period when it didn't happen. Then again he was running race fuel at the time (IIRC). Could the octane rating really stop the spark blowing out?

What about JohnS, has his car ever suffered from this?

Again though, do other cars get this when running high boost? I'm going to do some digging

Trappy - yes, TurboJ is having the same problem

Yes, I was running the stock 3.0bar FPR up until about June. With the bigger injectors, this was giving me enough fuel to give 400bhp

The reason for the remap was that I hadn't been mapped with the forged rods - the previous map had been held back so I didn't damage the standard rods (which didn't work, as I bent one anyway). To make use of the forged rods, I knew we'd need more boost, and to use more boost, I knew PT would need either bigger injectors or more fuel pressure - the 3.8bar FPR was a much cheaper option.

Flea's taking the car off me tomorrow evening and will spend some time playing around with it to understand what is happening.
