I threw a CEL yesterday with the map I was running.... standard timing, 91 octane, drop in filter, all headers, all cat-back. I took out the Unichip and went to the dealer. They said it was reading way too rich. (I suppose it would without the Unichip on top of things.)
I have been running a drop-in filter, header-back exhaust (front pipe without the 2nd cat) and Perrin intake hose... and this map seemed to perform well until the CEL.
So... called Unichip today and talked with Arron (very helpful man) who said to use the same map I was before but pick the 87 octane.
Does this sound right? Or, should I be using another map?
Thanks for the help.
