Tweaking Bosch FI
The search still continues for a car, I have been leaning towards Cavaliers and Saturns due to their ability to go into lean mode by either an HAI or resistor in the IAT circuit. The cars I have looked at have been in bad shape, so looking to alternative cars, I have found a 90's BMW that has the classic Bosch FI that uses the air box barn door MAF. Now my question is; Is there a way I can tweak it to get it into lean mode? Is there an IAT in the system that I can fool to lean the a/f ratio? I have read that the BOSCH system is harder to fool, can I reset the MAF barn door? Or EFIE the O2 sensor.
I know Ford and Mazda use a type of barn door MAF, as well as many other imports. Any ideas?
