Hey all. Another Z newbie question. How are people getting rid of the Check Engine light/ Service Engine soon light when putting on the test pipes or is this a problem. When I had my Spec V and I started prototyping headers we found that becasue the primary cat was removed we would get a CEL light after a few miles. We solved this by welding a new O2 bung further down the exhaust after the afterlighter. This cleared it for a while but the only real solution for those of us who ran with no cats was to use an O2 sim. Is there a similar problem\solution on the Z or are people using the $.02 fix (ie: electrical tape over the light)?

 

Bump for newbies

 

Nobody?

 

yOUR cel will NOT come on after installing the test pipes.
No worries there.

Thank you for responding. I do appreciate the info.

 

Actually your cel can come on after installing test pipes and yes I have checked everything I had to order the o2 sims and have been running them for about 3 months now.

 

I just installed my helix test pipes and have no problem with the CEL. Although the test pipes have bungs welded on for the O2 sensor.

 

Any info on the o2 sims, website how much? Thanks

 

I got my O2 sims from AEBS in Cali. when I had my Spec V. (Advanced Engine Breathing Systems). But I know Capser Electronics also makes some for Nissans. I would personally call Ben at AEBS. Great guy. Great shop. They build motors for people like Lisa Kubo, Dave Coleman, etc.

 

I got to AutoZone and have them cleared out for me. They do it for free. I haven't had a CEL for a few hundered miles though, since it came on last.
