I have a question about the service engine/slip/tsc lights all staying on. This happened when I installed the competition stage for stillen sc. I sent my piggy back to have it reprogrammed for the upgrade and had the problem and I sent it back to them to erase and reprogram again. But I still have the same problem and my motor doesn't start right away (seems to have too much fuel pumping in).

Anyone else know of this problem and/or anyone know what it might be? Some help would be appreciated. Thanks.

 

id like to know also. I have a stillen supercharger. and every so often all the lights will come on and it just wont start. just cranks and crank and cranks then after sittin for like an hour or two it finally starts....


in fact my car is at stillen at the moment... been there for like a week and i dont even think they have touched it.

 

Got a code scanner? Anybody that can afford to go FI should be able to afford some type of scanner for help in CEL issues. Sounds like your car is in limp mode, having a code will tell us what the ECU is having problems with. There are numerous things that can cause this.

 

I may have to get a code scanner. But looking at the instructions, there's a "Trouble Shooting" page. For long crank time but car starts, the possible cause could be the "Control Unit Wiring". I will be looking over all the wiring tomorrow to see if there is anything misconnected or maybe installed incorrectly.

azkt, who installed your sc? Stillen? If Stillen installed the sc, I'm surprised that you're having issues. Sounds like they have faulty piggyback programming. It's odd that we both have the same issues, except that mine actually starts within a few seconds. But lights are still on.

 

Well... I found the proplem. Apparently it was a wiring problem. One of the wires came out of the plug going to the piggy back.
