Does anyone know howcome engine lights comes on after installing the Vafc??? also how to fix it?? thanks

 

Uh... thats a bad thing. Remove your engine cable for a secodn then reattach. That will clear your check engine light. Turn the key on and start the car while watching the light. If it comes on again you must've hooked up the AFC wrong, check your connections... and hope you didn't just ruin your car. If it doesn't start at all and the check engine light comes on, your AFC is not plugged in. I did that once hehe... didn't realize the AFC was necessary to drive the car.

 

I had the V-AFC installed in my CLS for about 3 months.... After rewiring in several times I was still getting phantom check engine lights and throwing codes left and right. I dyno tuned it and only got about 6 HP and 2lbs peak gains with a 20 HP smoothing at 3800. The unit has some serious issues ..... I even rewired it to only accept reading to use it as a diagnostic tool without allowing it to change any readings and I still had the problems. All in all big waste of 40+ hours and $300... It hurt my 1/4 by 3/10'ths and altered the transmission shift timings somehow I am yet to figure out.... I reccomend posting it on ebay and dumping the overpriced but cool looking POS.
