Hey guys I was installin the apexi afc yesterday cuz my TP's are making my car run very lean and its sending a lot of gas into the engine and its giving my a really hard time. The car turns on perfectly fine but when I make any adjustments its slip & vdc light starts flashing and its goes into limp mode, what do you guys think? Is it a bad groung or connection, or am I choosing the wrong option? pls help ppl my car has been down for over a month and I miss driving it

 

Running lean and sending lots of gas into your engine are opposites. Test pipes alone will not cause a dangerously lean condition so you may have other issues.

Also I had an Apexi SAFC on my car and never had VDC or slip lights come on. Very few people have tried the AFC because it is very limited you can only adjust fuel and not timing. Most other piggy backs and reflashes can adjust both and usually many other things the SAFC can not control basically it is archaic and not much good on these cars.
