Default Re: I'm not convinced that my KE Laser isn't running too hot?!?

I don't think the radiator fan can really keep up...

on another note!

Laser will randomly go rich at idle, blip the throttle, and it goes back to stoich, only to revert back to rich 20-30 seconds later...

O2 sensor output to the ECU is from the MTX-L wideband, so its all good (no stock 02 sensor, but the issue was still there when using it)
TPS is just a switch, but seems to work as it should, and is adjusted correctly.

I tried shorting out/open circuiting the TPS, as its just a switch, but couldn't get the issue to reoccur.

The "stoich" AFR doesn't look like closed loop mode to me...

This was another log, where you can see the AFR cycling between slightly rich and slightly lean, till I unplugged the O2 sensor, and it went super rich, only to revert back to somewhere on the middle ;)
