Just wondering the 87 carburetors are computer controlled arent they? and if they are is there a performance chip you can buy for em?
I would think tuning it by hand, ear, vacuum gauge, tachometer, any of that would work better than trying to fight an ECM. I'm about to tackle the same issue with my '88. But I think these computers only control minor things like spark advance and when to allow the secondaries to open (from air intake temp, coolant temp, etc).
Is it a LeSabre (4th VIN digit = R) or an Electra (4 th VIN digit = V) Estate Wagon ? 307 Olds (8th VIN digit = H) or 305 Chebby (8th VIN digit = Y) engine ?
Okay, Now I know that, I have to search for a post on a German forum about a custom made chips for such an engine.
Most performance gains on the computer controlled Q-Jet are made on the secondary side. The primary side is controlled by the mixture control solenoid (thats the tick tick tick you hear when its idleing) and the o2 sensor. When you get near full throttle and beyond the computer basically goes into open loop and the carb acts as a standard Rochester 4bbl. The primary side is computer controlled, the secondary side is not. Mark
Erik, I think you have that reversed, the Y code is the 307 Olds, the H is the 305 Chebby. Both engines are gutless, a chip will make very little difference. It will give a little more spark advance and delay converter lock up.
