I installed my APS test pipes a few weeks ago and I knew I would throw the SES light. So I resetted my ECU for 24hrs, drove around and it came back on after about 60 miles. I don't mind driving with the SES light on, but does that hamper my performance in anyway? If it doesn't, I may just leave it unfixed. Thanks for the help!

 

doesn't effect performance...use Non-fouler method to fix problem for $25.

I'm aware of the non-fouler method... but I don't drive the car very often... it only comes out on the sunny days... I just don't want the ECU going into some mode where my performance will be hampered....

 

Good question. SES is signaling that the post-cat sensors are reading the same as the pre-cat sensors. In other words the non-existent cats are not cleaning the exhaust gases.

The ECU is one complicated computer. It may be increasing air:fuel ratio to compensate. Why not be safe a install non-foulers.

 

I guess I could always install the non-foulers... but I read in some previous posts that the CEL/SES light came back even with the non-foulers.. so I don't know...... but does anybody know if the ECU runs differently if the SES light comes on...?

 

it shouldn't, unless the ecu goes into limp mode

 

what's "limp" mode....?

 

won't rev above 2k, etc...

 

ok... then the ECU is not in limp mode then... which is good i guess... hahahaha... juss as long as the ECU is not screwing around with my performance... i'm all good
