My car is throwing codes P1132 and P1152....The explaination sniper gave ws HO2 switches- sensor indicates rich. It sounds like my car is still reading the rear O2s but idk...

 

your car is running rich on both banks, the rear o2s have nothing to do with those codes or the rich condition. im assuming you are tuning if sniper told you what the codes are. sounds like you have the fuel trimmed up too much.

 

^+1, those are codes for the front sensors--you can read what the shop manual list as possible causes here...

Do you have Special Forces or Commando. If SF or you used SF to make the base tune, what fine tuning settings did you select for the fuel modifiers?

If you tried to lean out the part throttle or full throttle settings, and did it as indicated in the SF documentation, I.e. set one or both to a value greater than 1.0, then you went the wrong way. The documentation is wrong and the labels in SF are confusing...

In Special Forces PT and FT Fuel Modifiers of less than 1.0 (0.5 through 0.9) will lean the mix, values of more than 1.0 (1.1 through 1.5) will enrichen it--again, this is the reverse of what the SF documentation says.

Also, changing by even 0.1 either way will make a big difference in the AFR. The selected value is used as a divisor for the OEM low (PT) and high (FT) injector slopes. Using the high slope as an example. selecting 0.9 will divide the OEM value (usually 19.15 #/h) by 0.9 = 21.27 #/h or some 11% leaner.

Selecting 1.1 would divide the OEM setting by 1.1 = 19.15 / 1.1 = 17.41 #/h, or 11% richer. Sniper warns in the docs that these are very sensitive settings. They are only needed if your AFR is way out of whack and connect be fixed with the RPM range based settings. They affect everything, not just closed loop, and are "on top of" any adjustments you make in the range based fuel modifiers.

Generally, but not always, the adaptive fueling algorithms can deal with selecting 0.9 or 1.1 for the PT and FT Globals, but selecting 0.8 or 1.2 will almost always trigger P1131/P1151 (lean) or P1132/P1152 (rich).

Are you playing with fuel trims without a WB sensor?

 

That's the thing I didn't do any fine tuning at all..I just put my mods into SF and it made the base tune and I put it on my car. I didn't touch any fuel modifiers.

 

Then it's unlikely the SF tune created the issue, maybe though--clear the codes, reload the stock tune, and see what happens...

If you like email the SF tune to me (cliffyk@paladinmicro.com), I'm not sure if my Commando template will be able to parse it but I'll give it a shot.

 

Reload the stock tune or reload the SF base tune? I will email it to you when I get home,

 

The stock tune--just to get back to ground zero.

When send the tunes send me the .pcm files for your stock tune, the base tune, and the tune that was loaded when you got the DTC codes.

 

i sent you an email. Thanks

BTW, I have a PRO M Pro Tube MAF calibrated for my 60 lb injectors which is why my MAF and injectors are set to stock.
