Post Turbo kit and CE light issues - what causes it and how to prevent it?


In reasearching the CARB legal turbo kit, I disconvered that the CE light cannot come on in order to pass the inspection. So...

For those of you with turbo kits, help me out:

1. What causes it?
2. How can I prevent it and still have the CE light work otherwise
3. Any other related info on the turbo kit and the CE light...

The only CE light I've gotten so far was from over-rich mixture. Tweaking the point where the RRFPR kicks in eliminated it.

Search on Larry Ganz's posts. He's detailed a bunch of them.

When I originally had the Minnam stage 2 kit installed, I ended up having 3 codes:
  • insufficient cat performance
  • insufficient EGR flow
  • MAP overpressure
The insufficient cat performance was due to the fact that Minnam shipped their kit with a "cat" that was really only a pre-cat. The insufficient EGR flow was because the intercooler interfered with the EGR valve placement on the MY98. The MAP overpressure was caused by the MAP sensor not liking positive pressure in the intake manifold.

All three have since been resolved for me. I now run a high flow cat (which allowed me to pass inspection this past January). The EGR has been reinstalled after RalliSpec modified my intercooler slightly. The MAP code is gone after installing a simple check valve so that the MAP sensor doesn't see boost.

Cool - it looks like all the issues are easily resolved.

Cutting the wire won't work - CARB takes your car and inspects it up and down, inside and out, before they run the tests. It's hard core....
