If I recall mine took a few days, around 5 or keystrokes to clear.

I think it helps to know what the fuse pull actually does. Based on the sticky,
http://www.camaro5.com/forums/showthread.php?t=38964

and the article,
http://thehorsepowerjunkies.com/vehi...-model-camaro/


The V8 has two spark timing tables. If it detects <90 octane via the KR, it goes to the table with lower timing to prevent damage. Pulling the fuse resets it back to the 90+ octane fuel trim.

Since the V6 just has the one fuel trim, the fuse pull shouldn't do anything. So here are the questions can help find out why people see an increase in power/mpg. Experts please step in.


1) Can you tune a v6 so it stores more than 1 set of tables? This can explain why the fuse pull worked.

2) For untuned, won't the fuse pull reset the long term trim and forgets the driving style of the driver? I imagine the mpg will be lower.

3) If #2, what happens if you do a fuse pull on V6 while 93 is in the tank? Would there be a "performance difference"?

Good questions.

That's odd. I tried to quote and it looks like it just copied.

fuse pull for our LLT bosch ecm does not work in the same way as it work for the SS that have 2 different fuel map. Its really there for safety reasons just incase you end up putting in bad fuel or something. All it does for our V6 bosch ecm is reset the ecm parameters such as TP, LTFT, STFT, KR, etc..etc.. so in the beginning it's very true that you might feel your car "faster" but this is really because those parameters are learning again so it might give you little jerks here and there when you push on the pedal which could be translated into more power if you don't know no better. Give it about 30-100 miles and I bet it will feel normal again.
