After the ATI install now I am seeing 2 codes.

1132 (HO2S-11 Indicates Rich)
1152 (Lack of HO2S-21 Switch Indicates Rich)

Is this one or two different sensors? May just be a coincidence.

 

Back out the fmu

 

yea. i crash told me not to ever back it wout more than 1/2 turn. i have mine all the way open, and i am having no problems. let us know if you get it fixed.

Definately still rich. I ran OK yesterday but the codes and surging (thats the word I was looking for) are back today. I will continue with the FMU.
Thanks!

COOL! Now I'm a Senior Member!!! Ha Ha...

 

crash, why do you think some run rich and some run right on the same setup? what is the variable. Also, i have been meaning to call you. i havent seen anything from JDM yet. so you may need to give them a call again. i dont know how long it should take, maybe we can give them till the end of the week.

Are the A/F ratio guages (Like a Pro Comp from Auto Meter) any good to have?

 

Who makes an analog Air/Fuel guage?

 

Sorry, I misunderstood. I thought you ment an analog 270 sweep. I have considered the digital ones.

 

just as FYI, with the FMU backed out all the way there are no more codes. Hopefully a tune in a couple weeks will get it right on.

 

If anyone is interested, there is a relatively low cost wideband O2 kit that you can build, or buy. I have the Autometer AF gauge in my RX-7, and it's, well, pretty. Yes, I was able to tune good enough to get past emissions, but it's really not a very accurate gauge due to the closed loop operation of that cars ECU.

For info, start here:

I have ordered (not received yet though) the whole pre-built unit for my 7, and hopefully can do a better tuning job with it. I'll share my experiences if y'all are interested when I get it installed.
