the engine went right in like a hotdog down the hallway and bolted right in, wiring i dont think was too hard everything is in accordance to gm tuners 1998 la1 obd2 wiring instructions bought an hp tuner turned off vats dtc p1626 and p1629 should i have ses light enabled for one? the hpforum net said just turn them to no error report...
// says something about c2 24 needing to be added for this ecm... this is a quote from the archive
Ryan is pretty sure he the issue is part of the message he emailed me earlier..
" While I was waiting on the laptop battery to recharge,I did some thinking. I recalled that I programmed a PCM for a guy with a Fiero swap that was running an 02 Grand Am 3400 and 4T45-E. I know he got that swap running AFTER he had some VATS issues so I searched back thru the emails we exchanged and found out what happened in his case. There were 2 problems,1 on his end and 1 on my end. On my end,it was a simple wrong number inputted for VATS type in the programming (I made the same mistake for you and the other guy who is having problems now). On that guy’s end,he didn’t have IGN B+ power connected to a 2 nd spot on the 3400 PCM that needed it: pin C2-24. 3400’s (and newer 3100 applications) require a 2 nd IGN B+ key-on power signal. If it isn’t hooked up,the check engine light won’t come on and the engine won’t be allowed to start because the PCM is still in a “semi-sleep” mode." can anyone send me a schematic of the correction
