Just had my comptech supercharger installed and today was the first day I drove it to work, half ways through the day my cel came on and now my afr guage reads around 10.3 at idle or so which seems to low and my car doesnt want to give any power when I step on the gas im stuck in a parking lot and dont know what the problem can be any ideas as to what might be the problem?

 

Check the esm. A wire or two might be looseor disconnected.

This Part is what hides positive pressure from the ecu.

 

Problem is I didnt istall the kit therefore I dont even know where to look or what im doing as far as the esm

 

find a DIY here on the site and read up on it so you learn more about your car before boosting it. If you dont then you will have to depend on a shop to fix everything.

more info on your setup helps...basic setup?
Boost psi??
EMS??
injectors??
other mods?

 

im guessing hes running the basic kit with stock ecu, otherwise he wouldnt get a CEL. How is your wideband setup? If you you are running the stock ECU you need to keep your Primary O2 sensor and have a 3rd bung welded onto your exhaust since the wideband probably wont play nice with the stock computer very well.

 

Its running on stock everything from comptech kit the only thing I can think of that might be the problem is the esm voltage wasnt changed the kit is for an ap2 but is on my ap1 and voltage was supposed to be changed but not sure it was

 

P.S. 10:1 AFR at idle would really hurt your motor so don't run it like that to much.
ESM... is that the stock piggy back type unit that comes with the kits? if so that could be it but from a stock AP1 and AP2 idle should not be that much different (I would think). Are you using a stock AP1 pulley or a stock AP2 pulley? Are you seeing Vacuum at idle? What is the CEL?

 

He stated he's stranded in his parking lot at work. At this time of night unless he has a OBD scan tool he will have to wait till morning to find that out. I hope you have AAA the best thing to do would be to tow the vehicle home at this time of night and see if you can get it taken care of at the shop who installed the kit. Unless you have a "buddy" who knows this kit inside out and knows how its set up on your car who can come out to help you in person, its going to be pretty impossible to troubleshoot it over the internet with you not having any tools at your finger tips.

Play it safe and get it looked at in the morning

 

I haven't ran it since this happened because the car dies out or has no power to run

Yes, this is the stock piggyback from comptech the ap2 voltage Is set at 2.93 I believe and for my ap1 should be changed to 2.88

I am using the stock ap2 pulley which only give me about 1-2 more psi over the ap1 pulley

Not sure what the cel is haven't checked it yet

All the wires from the piggyback seem fine and aren't loose but I don't think they were soldered

 

You need to get-up with the people that did the Install, Have them Trouble-shoot it, Also call the people that make this S/C Kit, no need to re-invent the wheel, I'm sure you're not the first with this problem. Also I rather see you a little to rich A/F Ratio than too lean. Check your Temperature Sensor, If it is Broken or not hooked up correctly, you will run in Safe mode, basically, your engine thinks it is constantly Cold and dump a bunch of fuel.
