I have tried every fix I found from searching this site. no matter what I do I can't get my LTFT mid and Lo to cycle. I made sure that the rear o2 is not disabled. I killed the battery and was able to get Lo to move once but not so much anymore. I am using ROM 96530706. My guess is there is some small setting i am missing or not set all together. I have FIC 950 injectors if that matters at all. They are scaled at 812. I tried scaling up but no luck. Any suggestions?

Thanks.

 

I have to disconnect the battery every time I check my LTFTs. Works once and when I disconnect from the ECU I have to disconnect the battery again to check them again.

cheers

 

So after every change I need to disconnect the battery? Did not realize that. I was under the impression that the flash reset the trims.

 

On the IX reflashing resets the trims, but not on VIII's.

 

Awesome......thanks for the replies.
