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?

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 haven't, but the pinout is close, very close.
I can post the pinouts tomorrow for the 98 computers. Dont know what the 97's are, though.
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

I am looking at doing this swap, does anyone know wher i can get the base calibration file for a 2001-2002 GMC Savana or CHev Express.
Thanks

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?
Will HPtuners even scan and/reset codes on the early "black" ecus ?
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.
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.
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.
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
