right as you may have gathered i want traction control on my car once everything is fitted. So basicly my question is, is it worth buying an omex ecu and obviosly waiting for the traction control to be updated or just use the bosch ecu and put racelogic tc on it. Also i might need 500 or 600cc injectors i guess flea would be the best person to let me know if its easy to map on the bosch ecu.

also how hard is it to fit an omex ecu? and how much extra mapping would it need? if its going to cost me £800 to mapp id probably give it a miss.

let us know your thoughts just a discussion so i can decide. reason why im debating this is because the omex 710 ecu is arround £900 and racelogic is arround £700 so would the omex ecu be worth the extra money compared to just bosch with racelogic.

Do you REALLY need traction control?

I find that the accelerator pedal works in both directions and is a pretty effective method of reducing power

I'm also less than convinced that traction control is not harmful to the engine

Fit good tyres and good suspension and a 400bhp Coupe can put down all of its power almost anywhere (and definitely from second gear upwards)

Call Phil Lanes on 07717885420 with regard to installing + mapping the OMEX.

I've heard negative things about the race logic TC. I would do without TC personally as I find it intrusive on every car I have driven that has it, but if I had to have it I would go for the OMEX.

Flea is the chap to get in touch with regarding live mapping the bosch ECU.

reason i want traction control is because i find it quite dificult balencing clutch and throttle to eliminate wheel spin and thats at 340bhp id hate to imagine what it will be like at arround 450bhp. i understand that other drivers might be able to eliminate wheel spin (nigel your of them) but maybe i just dont have that ability. also tc is a safty feature, with 450bhp at tap im sure traction control is somthing to consider.

suba where is phil lanes i will most probably give him a call

Phil Lanes is in Lincoln and is mapping my car at the moment.

Suba - OT, give Phil a bell and let him know about the brakes, was speaking to him about you and said he never heard back about compbrake

Another option to help you with launching would be for you to use a boost controller that allows you to run lower boost in 1st gear.

Many cars with racelogic have found they are quicker over a 1/4 with it off....

Another thing to consider is the power delivery of the turbo - I'm guessing that you are using a GT28RS, which is very on/off. A GT30 will spool more slowly giving you traction due to a more progressive torque curve.

Begbie - Lincoln as in Lincoln near me (Grimsby) i didnt know that there was anyone around here that would be any good at mapping coops

Dan, yes, Lincoln as in Lincolnshire and he is here

sorry for spamming but - would he be ok to map mine? with a standard ecu?

Call him and find out, worst he can say is no

yes it is on/off and i do have a boost controller that limits boost it 1st gear.

good point thanks

don't know of problems due to excessive use of TC, but my car with more than decent tyres, on Greek roads (yeah, I know but nothing I can do about it other than immigrate...) is SAFE with TC on and fun-> dangerous with it off. Surely you can be v.careful all the time, but in the few cases you're not it will make a hell of a difference!
[plus it makes a hell of a noise , wonder why none mentioned it!]

V.

yiasou vaso yes yes im greek too lol you have racelogic on your car don't you? also dont forget roads in greece are very dry and heat tyres up well which makes them stick better imagine going round a bend in the rain, in the uk and getting it wrong. (on track obviously)

Like Nigel, I have never felt the need for traction control be it on the roads, track or dragstrip. Perhaps it is simply familiarity, I have certainly become very used to driving high powered front wheel drive cars over last 4 years! I also find the Apexi AVC-R controls the boost very well between gears ensuring all the power is put down with minimum fuss, except sometimes in first

Re injectors, no problem to run with 500-600cc injectors on the Bosch ecu, I currently run with 600cc. You would be looking at £345 for a stage 4 map, although I would recommend the Big MAF conversion which is £95 and £395 for a stage 5 map.

Good price puts the price down quite a bit!! Looks like I might be giving you a call soon most probably for a stage 5 map we will see how I get on with the engine rebuild first.

i hav a fair it of racelogic experienceon the 20VT. I seriously wouldnt bother, it cuts ignition quite suddenly, which is why as Suba has said, cars made he quarter mile quicker with it off.

Also launching you modded coupe in lower gears (1st specifically) is the first way of encouraging your PS belt to derail and wallop your cambelt.

High powered coupes are ideally used above 50mph, where they are suited best.

Traffic light monsters are not possible.

TC is amazing in the wet both in a straight line and around corners.

John

looks like theres quite a few mixed thoughts for the racelogic i supose who ever has been lucky enough not to have any trouble with them think they are brilliant. anyone have an omex ecu??

Rog,
not driven a 20vt with racelogic, but mine is rather smooth getting into the "cutting".
It is also fairly easy to alter the cut duty cycle so to speak and make an even smoother delivery (not that I have done so, but the s/w is there and easy enough to edit.

BTW, since we have an open discussion on the Greek forum on why some modded 20vt have a tendency to jump teeth (through derailed PS belts) would you care to elaborate the launching relevance. Cannot quite get the point.

TurboNick,

hi there, when was the last time you drove in Greek roads mate? Your theory is good, but the tarmac is crap (mostly) so it doesn't work like that. I can easily spin 4th gear in many roads around here...

Cheers

Race Logic runs fine with Omex ECU.

I know as I had both systems together runing in my 147 turbo

Both now sold as Im going full Motec M800 and digital dash display setup.

Right Mr OMEX to the rescue

I have fitted the OMEX 710 into Squids’ car and that has already been mapped. It needs a few more tweaks as we ran into some oil/ intake temp problems, but so far it’s looking really promising.

I also have an OMEX 710 ready to install onto mine very soon. It can also control NOS/Aquamist really well. The launch control is another great feature. Data logging to is also help full.

Regarding TC the OMEX is setup to use it but the modular that controls it has not been released yet so as it stands there is no TC but when it is released it can just plug in. I don't know how good their system will be but I’m sure if its setup properly it will be great. Best to call OMEX and speak to Andy.

The mapping is fixed at £450 all in and maybe even cheaper if I give you my map once the colds starts are perfect. We both run 630cc Siemens injectors and MAP sensor. If you need it fitted I can come to your place and wire it in while you wait

@nigel hello mate when coming onto boost in 2nd my car would go into a wheel spin sometimes all the way to the end of 2nd and i am running toyo t1r's and i do rate them as they stopped me wheel spining with a gt28rs,then i went gt30 and its back

I'm going to see Andy tomorrow so I can ask on your behalf.

I dont want to go off topic here - but there is a lot more to eliminating wheelspin than the tyres.

you know what as soon as i typed that i thought to my self roads in greece are crap!! lol apart from in maybe athens since after the olympics lol



sedicirich that would be brilliant. If you could ask how far away they are from finishing their TC and how long it will take them to release. cheers

Turboj by the time i buy this hopfully, well more than likely suba's car will be done and maybe we could have a review on it . £450 is a good price considering the work involved.

i have done suspention mods and things like that already suba i just want to know what would be best. I know some might disagree and say your right foot can elimiate wheel spin and things like that but i see it as a safety feature, your right foot aint gonna be right all the time. i dont know how the tc is going to be on the omex ecu i wonder if we will be able to turn it off and how much spin it will actualy eliminate?

"Traction control is in advanced development and will be a free software upgrade to all users when completed." -OMEX

It won't eliminate any wheel spin it just controls it, so it will only be as good as the person who maps it. I have access to some really good TC control algorithms that need testing but will have to wait until the OMEX TC upgrade is finished.

sound iteresting ill wait to hear bout subas car im sure everything will be fine. omex is looking tempting.

OK, as someone who has been driving a Coupe with the Omex 710 in, all I can say is that it performs very well so far. The car is not perfect yet as I still have to get the cold start and idle perfect, but that is all included in the mapping price.

I had some problems with the intercooler being full of crap and my aquamist pump failing for the second time. but the car still made 414bhp & 414 ft/lbs of Torque, which is quite astonishing to drive on the road.

I do have to be very careful with wheel spin and because of this I restrict the boost to in low gears. For the big power runs, the car was mapped to 2 bar. If I use that on anything less than perfect road conditions it can spin the wheels in 4th.

As said above, when driving a car as powerful as this on the road you quickly learn that stomping down with the right foot can lead to trouble, so you will have to adjust your driving style a little. However, people will inevitably tune their cars in increments so it not be a big problem.

All in all, I am very happy with the OMEX. It makes me confident that the car can make the best use of the modifications as I always felt like live mapping the Bosch ECU was not the best solution. Also, it is nice that there are literally hundreds of tuning companies that will be able to map a Coupe running an OMEX system.

Other issues to consider are that you will need to convert to a MAP sensor and that the wiring loom is extra, but I can't remember how much.

As Jason said, the traction control will be a free software upgrade from OMEX when they have finished it. I believe they will use a similar system to the one used on big powerboats to stop the engines over revving through jumps.

If it is better performance you are after, the OMEX is a much better option than the racelogic, and it may prove cheaper when you factor in multiple live mapping sessions on the Bosch.
