488 488 with Fi Exhaust and CEL

Speaking directly from personal experience, you need to understand what code is being thrown first. The capristo unit only clears P-codes 420,430, 3270 and 3271 so if you are getting a CEL from a different code the OBDII plug will not do anything for you.

 

Please let me know what you end up doing to fix the issue I just bought FI Catless Down pipes and looking to buy FI exhaust so Im sure I will run into the same problem.

 

I use capristo and it works great. I have a 100 cell Kline and novitec valved

 

resurecting this thread to ask a related question .. does anyone have experience with CEL code P014A "O2 sensor delayed response - rich to lean ..."

I am getting it periodically on my 488 with Kline 100 cell cats. This code is not in the list of codes that are cleared by the Capristo OBD wizard and that made me start to wonder if I actually have a faulty O2 sensor rather than it is a consequence of the Kline exhaust system.

 

Hate to grave dig, but did you ever figure this out? Running into similar issue.

 

I ended up replacing the Kline with original exhaust

As an aside, I found the kline exhaust had a resonance that actually made me feel ill on long drives. Quite bizarre and did not notice until the OEM was back that I could do a drive and still feel fine.
