    Sorry to Hijack, but I am in the same boat with a 97 with a 454. Has anyone put a 98 black box into a 97?

    I'll see what I can find.

    I know O2 sensors are moved, probably injectors down a bit too. But most else is very close.

    For some info on the 98/99 PCMs, check out this page on diy-efi.org. In the bottom, they have schematics for the PCMs with the pinouts listed in each schematic. Somewhere I have complete pinouts for each connector. Ill see if I can dig them up. http://www.diy-efi.org/gmecm/ecm_info/16250279/

    The 96 C/K list 5.0L, 5.7L, & 7.4L
    I didn't check to see if the pinout for the 7.4L is the same on the other years

    Thanks for the cal files, I appreciate it, and thanks for the warning, I am sure they will be closer then what I am going to get with the job that is going to show up today. Another shop is putting a rock crawler together and I am going to tune it, he has it running after the ECM swap, but he said it cherries red's the header as soon as it starts. Other then that I don't know anything about it. So, I am sure that this will be a step in the Right direction.

    Has anyone thought about using one of these 411 PCM's or even the 98-99 Vortec PCM's on an LT1? Seems like it'd be alot easier to put a distributor in a LT1 than it would be to buy a huge 24x LS1 coil pack conversion. Just a thought that I may try to tackle with a buddies Impala. We really want HPTuner support for his car but don't want to go through all the 24x conversion to use coil packs and this seems like a little easier to do than the other anyway.

    Whats your alls thoughts on that?

    Does anyone have the pinouts for the 411 PCM Express Van?

    I think the newest beta can.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    So Ive got one of the old "black" ecm's with a service number of 16244210.
    My scanner is 2.23.3616.25998 beta and it will connect and read the basic sensors such as throttle, coolant and map. Editor doesn't work unsuprisingly.
    This is a complete loom that i have picked apart and intend to try starting the engine - will report results.

    That beta is about 2 months old, far from new.

    97-98 wiring differences

    So I have been cross referencing the differences in the 97 and 98 computers. I am looking at going to the 98 computer for my 97 Vortec 454. I have found 13 differences in the pin outs that do not have a cross reference in either year. Do any of you guys have any idea about these? I have them in the spreadsheet here.

    I know there is a bunch of emissions differences between the 1996-97 and the 98-00 engines. Differnt canister purge equipement. The 96-97 trucks for for the most part do not have VATS, whereas the 98-00 truck will have VATS.

    Just an update. I ended up going with a 0411 swap. Everything has turned out good. I would recommend the 0411 for anyone with an OBD 2 OBS truck.
    1997 Chevrolet K2500 ECSB L29/4L80, Mid-length Headers, Cat-delete, Custom Catback, Airlift Airbags, 0411 PCM Swap.

    2004 Pontiac GTO M6 Ported Dart 225s, SI5 cam, Ported FAST 90, SLP LTs, Bassani catback, Pedders Track Coilover, GMM Ripshift, Spec 3. Numbers to come...

    just a few tweeks is all i want

But I just want tweak my trans parameters, fuel, timing, and a few other things. If they offer support for 96-97 I'll buy it, but it's not worth the trouble of a 411 swap.

    Bump. Plugged into the van. Scanner seems to be working great. Obviously no editor support. Any updates or as of now is an ecu swap the only way ?

    About to swap the 350 vortec in my van for the 454, will need to do something. Probably the 99 454 ecu
