ive got my engine swap up and kinda running. its a 95 3.4 camaro motor in an s10.

the PCM im using is from a 1993 lumina with a 3.1, 7727 ecm

i need to get my scanning software up and running, so i can see what sensors are working right, and what arent.

to that end, ill need the stock files. but i cant seem to figure out what they are for the lumina ECM. im not ready to start tuning yet, so all i need is the stock stuff. when i retune ill go $A1, as there is some autotune stuff and a lot of hacks out there for it.

ive looked at tunercats website and found nothing. moates has a lot of files for the 7727, but im not sure what i need.

thanks
Michael

 

go to the TP downloads section, definitions page. download the A1 XDF and A1 ADX i have posted there.

a BIN may be a bit trickier though. you said 3.4, but what trans?

 

so this ECM is already running the $A1 code? cool.
the bin i am eventually going to run will probably need to be built over time. its an iron head 3.4 from a 95 camaro, backed with a 5 speed and 3.42 gears.

thanks for the help, Mr. Saar. you and raven have been the biggest helps i have gotten on this swap. seems to me that you guys are the go to guys with these kinds of things, and i really appreciate you being there and holding my hand through it all.

 

if that ECM really is from a 93 lumina, it should be a 16149396, in which case the stock chip in it is $DF, but it will act perfectly normal with a $A1 BIN loaded into it.

and it would probably be best to start with a BFUZ BIN and stick the VE and spark tables from the latest iron head 3.1 BIN running $88 on it, which as far as i can tell is BAWX(latest one i have anyways). THAT should get you started on a good path.

 

the sticker on the side of the car at pull-a-part had said a 93, but the number on the ECM is 7727. GM sticker.

so, the $A1 is the one i need for the ADX/ADS files to check my sensors and wiring job. ill download that to my laptop when i get home from work.

ill start pulling all these files together, and start making a bin for when i begin the tuning. then, ill start asking a lot more questions.

 

what is the BCC of the MEMCAL you got with the ECM? that will tell if it's an A1 or DF BIN quickly. the datastreams are similar, but not exact. need to match ADX with BIN or else you'll have problems REAL quicklike.
