165 MAF computer

[Gabe]

You are using the 10K ohm resistor aren't you?

Have you tried Craig's latest program?  It seems better able to cope with com
problems and even has some adjustments.  In fact, I can even kill my engine -
close my laptop (suspend mode), open my laptop back up several hours later,
restart the truck, and the program will take off right where it left off - very
cool (especially with the MPG calcs I've been testing)...

My ECM's com locks up occasionally, kinda aggravating - from what I've heard
this is really common for the 165 & no one seems to have an answer.  When it
happens, just gotta kill the engine for about 15-20 sec and it's good to go
again.

I'll play around with mine a little more and see what kind of numbers I can come
up with
