We spent A short time with the Tuner Pro scanner. We have a lot to learn with it. Do you see anything that jumps out at you other than the battery voltage. I am charging the battery now and will attempt another scan tomorrow.

Wow, what lousy pictures I?ve posted. I can?t even read them myself. I?ll try again tomorrow

Re: Extreme rich condition
 

What ADX file
Are you using? Where did you get it from?

Re: Extreme rich condition
 

The data has a lot of logical conflicts. The ones that are the most notable to me are that the right oxygen sensor is at 0 mv. and the system is in closed loop mode. Normally the system will not go into closed loop if an oxygen sensor is not transitioning. This suggests that the wrong data is being listed for one of these PIDs.

The calibration is based on an 8EA configuration file. The scanner is showing an 8E ADX file. Try running the scan with an 8EA file.

Re: Extreme rich condition
 

Let's see if I can explain this intelligently. The file we were using was 8E.adx and it was from a list that the website offered. It states it is for a 90 LT5 but they didn't list one specifically for a 91. All they listed was a 90 or 93 to 95. When my brother and I get together again, we will search for a 8EA adx. Does that makes sense?

Re: Extreme rich condition
 

I have all of them. I put them together as the one you got while it works for you since you don't have a CCM. Mine I know will work correctly. What year do you need? 1991. PM me your email and I can send it to you

Re: Extreme rich condition
 

Guys whether it is $8E or $8EA it will use the SAME adx as the output info from the ECM stream is the same..

HOWEVER.. Perry says he has a 1991, if it is wired for the a 1991 it should be $AF or $AFA and he could yuse the 8E.adx and most of it will work, but I sent him the one I made for the 1991 and should work for everything..

Re: Extreme rich condition
 

I misspoke. His calibration is of course, a '91. It uses the AFA definition file.

Re: Extreme rich condition
 

Marc thanks for the clarification. I have sent him the 1991 ADX.

Re: Extreme rich condition
 

Using the file that Jeff provided, we were able to run some more tests. Here are the results. I don't know why the right O2 sensor doesn't register anything. The engine runs smooth in open loop but not in closed loop. No smoke in open loop but starts smoking when in closed loop. Sorry about the sideways pictures.
