Back fire thru TBI

Sneakysportsman · 03-20-2008, 09:13 PM

I have recently detuned my motor to a smaller cam. When you first crank it up with the custom chip is has lightening fast throttle response. 800 to 3300 in .25 seconds. Super amazing. But after it warms up all the glimmer of the super fast throttle response disappears. I have done everything I can think of under the sun. I even have my own programming software to alter the ECM.

Throw any suggestions that you might have.

Given that it's you asking, I'm not offering anything on the engine. I would think to look at what the ECM is thinking for warm conditions. Still need to learn what games can be played from there, I have some reading to do.
