Ok, so I have a 95 OBD1 S14 5 spd. Swapped in a 95 OBD1 Automatic ECU to get rid of the Speed Limiter. Everything works fine, except for the fact that when I turn the car on, I have to blip the throttle once or twice or else the engine will stall. Anyone ever have this problem?

This is on a KA of course :D

hm..
although i have a s13, with the same "mod", i dont have any starting/stalling issues.
i DID with idling, however that receeded.. or i just got used to it. :/

On one s14 I went manual to auto ecu and there was/is no problem.

On the other one when I switched the manual ecu with an automatic one, I discovered the throttle needed to be blipped.

They both were origonal manual cars.

Live with it? Not sure what to say.

There no other way around it? I thought there was a particular wire you could cut.

try another ecu, also does it idle correctly at 700-800 rpm after you blip the throttle. or does it sputter around.

maybe something wrong with the ecu, or a short...try a different one, or maybe check the wiring harness

i switched a 96 auto ecu into my 98 5-speed. I didn't have any idle issues but i did get a cel for emissions.

I already answered the question.

Don't bump old threads with guesses.

i Did the same swap on my friends car.it did the same thing but it was the water temp sensor. it would start funny and shoot white smoke.
