I have a 1989 Iroc with a 350. Only mods are headers and custom dual exhaust, AIR removed. AFS-74 3-wire O2 installed.

I am new to tuning these engines and would appreciate any help you all could give.

I have looked on various forums and tried everything I have seen to fix this problem and nothing seems to work.

I am using Tunerpro RT and a moates autoprom unit.

I have loaded the 6E xdf and 1227165_6E adx from tunerpro's website

The problem is whenever I try to datalog I get useless information and the number just start jumping sporadically.

This is a youtube video of the issue.

I have tried adding in a 20ms pause as I saw suggested for a similar problem on the tunerpro forums but it didnt help.

With all this being said, there have been a few instances where I did get good data out of the system but i would change screens and the it was back to this sporadic data again.

I would appreciate any help regarding this matter.

 

Did you ever resolve this? I have a an issue that I get all the correct readings and then random garbage every 10 seconds or so. I am hoping there might be something in common.
