Engine Set up

[flinny]

Is it possible to set your engine up without going on a rolling road ?

I'm convinced mines running rich and could do with a little fettling but don't want to run the risk on a rolling road. Is it just a matter of taking it to a specialist and them plugging a computer in ?????

Easiest way to get your idle mixture checked is take it to a friendly MOT place and ask em to stick it on the exhaust gas analyser. If it needs adjusting there are air bypass screws on the air flow meters but they guys should know that. You can also run it gently through the rev range whilst on machine to make sure it doesn't do anything untoward, if it does you need to be looking at sensors and AFM's as once you come up from idle speed its all controlled by the ECU. Ignition timing can be checked with a regular strobe light but would not recommend trying to adjust as you need the ECU in test mode to do it correctly.

Good luck,
Carl.

My ex Ford indy garage boys moaned a bit but did plug their fault tester into the ECU and found none and when it failed the MOT, they plugged it into their exhaust anylsis machine and took it back to 1.5% in about 30 seconds, only comment was that the AFM was upside down to what they were used to.

Not sure what risk you run by using a rolling road?

You don't have to redline your engine to use a rolling road, yes people use them to see what max power they can get out of their engine or to set up a super chip. But their primary use is to simulate the engine running under normal driving conditions whilst monitoring the engine so you can adjust it to run optimally.

Give someone like Austec a call and explain your concerns to them and they should be able to explain the in and outs and any risks.

Thanks for the mail Dale.

Colin, I don't have any specific concerns with regard to putting the car on a rolling road. Only that a guy in our region, I think it was Foxy, did and his engine let go. As much as it tries to recreate the road environment I would have some concerns. I've just spent a fortune on the shocks and springs so don't want to incur the expense of an engine rebuild.

I'm gonna try mycroft's guy first, he's local, and from what he has said sounds like to work carried out is pretty much as suggested on here.

Thanks all for your help, I'm a little more in the know now.

Bring on April 1st and a taxed TVR..... Hoorah
