Yes this is exactly my understanding, too much fuel drowns the spark, I know this cos my car runs excesively rich up top (10.5:1). The only reason you want a bigger fuel pump or bigger injectors is cos you have fitted a bigger turbo or more boost and your standard fuel system cannot manage it. Idealy you want your fuel map to be set just before pinging point, that is where you are going to get the most power without blowing up your engine.flav wrote:You only would use more fuel if you needed it, for instance if you turned up the boost. Manufacturers make the car run a little richer than it should thus ensuring a safe working environment..so in actual fact you will gain a little more power 'leaning off the mixture' or bringing it to where it should be for a given condition. This does not mean making it 'actually' lean...just fine tuning. As far as the chip goes its a plug and play chip inside the ecu..remove the old, put in the new. I have one in the dash with a TC06/T3 turbo and without this chip the car is noticably slower and hits the fuel cut, although for some reason, with the chip in, it is a bitch to start sometimes so mabey i need to play with the tuning a little. I havent done much with it but when my dash buzzed past 7000rpm and was still boosting hard i thought this was worth the $200 i paid for it. You are all welcome to come and have a test drive. (this DOESNT mean burnouts at flavs expense!).
With your Dash^ what ECU do you have?
My gf lives in Doncaster, I wouldnt mind checking it out sometime.
