So, my car is running pretty rich at idle, and stumbles a bit off-idle, but seems to do well in the mid-range and top end. I know its running rich because it blew 520 Hydrocarbons at the smog station... with the catalytic converters installed.
I'm running a stock Cobra MAF, 65mm BBK throttle body, Cobra ECU, Cold Air Intake, brand new IAC valve, 24# factory injectors and running a Walbro hi flow fuel pump at 40psi)
I talked to a local tuner that has done a lot of stuff with OBD1 cars (mine is basically a 1993 Cobra EFI setup), but they said the best they can do, is run a baseline on the dyno to see where everything is at, and if the idle mixture is rich, then the best that they recommend is running a Megasquirt EEC direct replacement. I was really surprised. I thought that there were a number of folks that still tuned these old OBD1 cars.
Does anyone know of a tuner in the Pacific NW, preferably in the Portland, Oregon area?
Or.... I have been looking at a couple of different tuners, like SCT, BAMA, etc., does anyone suggest any of these, and can any of these potentially remedy a rich idle setup, either with a tune, or by manually adjusting maps?
Thanks for any advice you can offer.
