One thing is fairly clear here, people who seem to have spent most of their last couple of days sniping at each other about this RR and that RR always have an excuse about their graphs and why they're not right....

Oh give it a rest now Did i say power run, no. Did i say AFR check, yes.

The dyno is at UNI and I don't know how to use it my tacho shows 7000rpm the dyno shows 5500rpm . If I had a portable wideband I won't need to roller it would I? As I said all I wanted to do was check AFR why does anything else matter? It doesn’t. You can see it stays nice and rich towards the ends and that’s all. The problem with going lean towards redline, mind doesn’t do that, the PT map was fine.

I had driven the car for about a month after being mapped and wanted to check the fuelling didn't stray/adapt. It didn't. It was with GT2871R with 1.6Bar boost (figures are below from Dastek). The car has been remapped since then it now runs 2Bar if it doesn’t miss

Jason you can't post a graph like that with nothing on it, you may as well not bother. If you don't want anyone to know the horsepower results that's fair enough.

Anyway, the fueling looks fine towards redline although a bit too lean coming on boost and in the midrange.

I wasn’t going to bother but I thought it might be of some use. If I didn’t want people to know my HP then I would have just removed the HP scale. Why would i need remove RPM? My last power graph is in the hall of fame anyway.

I really wanna give it a proper run and AFR check since the last remap but just haven't got the time

Why did you remove the rpm? Anyway, talking of spool up in the other thread, what's it like on your GT2871R with the raised comp?

Because the scale was completely wrong and it would confuse people even more. (I wish I didn’t bother now)

Spool up is lovely. Raised CR all the way I knew it would work, . 5th on the motorway then WOT soo much torque it just pulls and pulls. I really wanna dyno this bad boy at PT to compare from the last run it made. Just wanna sort the missing out otherwise what’s the point in going. Been so busy haven't even had time to change to them plugs you told me to get.

I might PM you some vids

Simple indeed, maybe goes like this turboj --> "its only running what??" but ive told evryone on Fccuk its now im gonna have to use paint to cut these bits out to prove my Pt map is at least fueling ok .

(turboj goes to leave the dyno and heres operator shout) "you forgot your coat buddy





turboj this is pure banter you got to expect it after editing the graph as tbh IMHO if you know its running the figures below your sig at least now then who gives a fccuk what anyone else thinks (i dont)

I have converted the lambda to gasoline AFR as that's what most people understand. A little bit rich at the bottom end and then quite lean coming on boost up to 4000rpm as I am sure you have made 1.7bar before that point with the quick spool. Ok to redline.

Anyway, why not try another dyno for comparison and this time get a full afr trace

My graph is in the hall of fame go look.

Actually Jason what was your wheel power? It doesn't matter if the rpm was out as a Dyno Dynamics rolling road calculates wheel horsepower via inertia (it doesn't use coastdown ) so regardless of rpm the wheel power is correct.

Also you really are running quite lean between 3000-4000rpm as you will be making 1bar of boost at around 3000rpm and 1.7bar at around 3500rpm which is not so good when running 13afr. Worth getting that checked out as detonation is most likely when coming on boost and at peak torque.

Going by memory the tacho was 1100 to 6000 on that run. I don't know how that changes your scale. But your right I need a proper power run with AFR trace. This was mealy a test to show that it didn't run lean towards the top end so please take it as a pinch of salt.

With Dyno Dynamometer you can only graph/print two plots (stupid really). Didn't look at WBHP not intrested, only concerned was fuelling trace.

Its been remapped since then. This graph is 16/09/2008.

What was the flywheel power that you cut out as we can get the wheel power from that? Dyno Dynamics don't use coastdown so we can actually take the set % from that. Anyway, may as well post the full graph now.

have I missed a trick on this forum ?

Not being funny lads, but there seems to be some questioning about the obvious here with regards to the results etc...

Sure there are 2 sides to the story, but SURELY, isn't it about the aim of making the car run correctly ?

I am still a tad disappointed that my block still won't produce the sort of BHP / WHP ( whatever its fcukking called ), however on the road, it is fast enough at the moment

let's not loose sight of the fact that thankfully there is a CHOICE as to who you want to map your car

bit like marmite I suppose

IMHO

Taz, your right but ultimatly if someone is modifying there car they are trying to improve power and performance, im sure you did'nt go through all the expence and hard work to convert your car to a 2.4 so it would run nice, you wanted more power, there is nothing wrong with that

Right life story time:

Changed Turbo to GT2871R then mapped at PT on 5/7/08
http://www.online-presence.co.uk/_coupe/rollingroads/148.jpg

Maxxed out injectors that’s why it only goes to 5750rpm. Limit set there.

19/7/08
Changed fuel pump and fuel lines. Back to PT for AFR check. Sat with Rob in the car made 352BHP/322WBHP/339FT/LB didn't bother print graph no real difference as it was still running out of duty at 6000rpm ish. Rob said get bigger injectors.

Ordered bigger injectors but not fitted yet.

16/09/08
Got scared after talk of maps leaning out over time and took car to uni for fuel check. Were not suppose to run the dyno after 5PM due to health an safety but I did it anyway without the dyno operator (naughty, naughty). Rushed it as was only interested to see if AFR was lean. It was fine. Got the graph above.

15/11/08
Went to PT fitted 16VT injectors then re-map. Car finished and mapped to 2BAR goes to 7250rpm no fuelling issues. No power run due to broken dyno. Calaido said come back anytime for a free run...haven’t yet.

I show you the uni AFR because somebody asked that’s all. It’s the only fuelling trace I have but now the whole thing is irrelevant as the car is running fine just lacking a power sheet.

Jason the graph you link to has BHP plot on it, but you have cut out everything. If you show the full plot then we can compare it against the PT graph, it will be interesting to compare as the Dyno Dynamics is a well respected dyno the world over.

Flea do you not get it...The dyno was not calibrated properly I don't know how to use a dyno the operator was not there, so how could it be setup correctly?, how may time do I have to say this. I didn’t do a proper power run I just used the dyno so that I could watch the AFR on the wideband for all I care the dyno should have been switched off it makes no difference I’m only interested in AFR. It’s the same as me logging a wideband in my car without a dyno no power figures.

Like I said before once I sort out my missing I will do my power run at PT then I will drive to uni and do a PROPER power run on the Dyno Dynamics and post the results in the forum. I don’t have a problem doing this stop making out like I’m afraid to show results, I’m not.

Jason I'm having a play with you. Of course I get it, I think everyone does

Good
