Annoying SMOG issues, ECU only passes 3 out of 7 monitors... HELP!

[Jesses240]

I also have the Auto eng software, and honestly from a professional standpoint, unless you buy the 800$ package its not really worth it... but if your not professional every day use then its great.

I have only seen 1 ecu that has actually been bad that replacing it fixed the problem, it is very rare.

Worst comes to worse, just find someone who has the same 240 as you and borrow trade ecu's for a day.

Most of the time when I take customers car through deq after fixing issues/dtc's... I don't have to drive more than 10 miles to get enough monitors set...

you can have up to 2 monitors not set here in oregon. Don't know about your state.

Yeah, the $200 package, which I got, is fantastic for non-professional users, like myself. But yeah, as far as doing it for a living, obviously something higher-end would be required.

But yes, I thought it was quite strange that I wouldn't pass my monitors in a short amount of time. So right now I'm trying to locate another ECU for a 96 Manual. Does anyone know if a 97-98 manual ECU would work? OR are things to different in those models? Thanks

I would just like to bump this, to let everyone know I bought a different ECU from a fellow member on here (drifto-san, thnx btw) and just installed it and took it for a drive tonight (1am) and only after 10 minutes of driving it's already passed 5 monitors!!! Including the EGR monitor and O2 heater sensor (2 that didn't pass with the old ECU).

So it is now confirmed that my ECU was in fact, BAD ! ECU's do go bad, especially OBDII ones, let this be known!
