Hi,
Hoping to find someone here that can burn a MP stage II 670 chip for a friend. This is a MP stage II LM with the socketed board. Friends 86 GLHS was working perfectly then suddenly started running VERY lean under boost. Even with alky injection A/F is 15-16:1 under boost! He has wide band in vehicle and after checking all the obvious stuff, he re-installed his stock 86 GLHS LM and all the lean problems went away. WOT then went back down to 11.8-12.0 :1. So pretty sure it is bad LM. I've personally seen and heard of this happening before (mostly with custom cals).
Hoping that a new 670 chip will cure the aliment & get him back on the road. Obviously willing to pay a reasonable amount for this service.
Please PM me for his address or phone # if you can help, or know someone that can help him. He is a long, long, time TM owner but pretty much doesn't post on the forums.
Thanks,
Todd
