16144288 TBI ECM upgrade to 16168625 TBI PCM

HandyMan, I think one of the basic benefits of switching to the 8625 PCM is tuning. Because the baud rate is so much faster, you get more data points, making tuning easier. The $0D masks are decently documented, and like you said have the added benefits of doing things like computer control of cooling fans. Dave W. is one of the good guys on this board, and is a really knowledgeable tuner. If you want to get into getting your S10 tuned properly, grab a copy of TunerPro RT and start learning it. OBD1 may be archaic, but there is a lot of support for it, and it is much less expensive to tune.

Hey Jim, thanks for your comments. I guess I will press on with my ECM to PCM swap effort. At this point, before I move onto the repinning process, I need to secure a the proper harness connector. I found one on eBay...

Can someone give me feedback if it is the correct one?

Thanks

They sure look correct. I just went to a JY and cut them out of a truck

The items listed on ebay link are the correct parts.

I usually purchase my parts from Mouser:

I can be hired (Old School EFi) to tune a chip for the '7427 PCM. Send me a Private Message (PM) for the details.

I like the newer 93 ~ 95 TBI red / blue connector PCM because it has two timing tables / two spark tables (near idle / off idle), can be configured to stream WBO2 into the data log, operate a 700R4 / 4L60E / 4L80E, and run an electric fan(s).

Myself and other members have developed an advanced Excel spread sheet to "Crunch" tuning a '7427. see attached screen shots

Darn, I just tried to order the item on eBay and noted the seller doesn't ship to Hawaii...

Dave W., thanks for the alternative from Mouser. So, do I order one of each of the first 4 items you list to make a complete connector? I'll also order a few pins.

Now with regard to your last comment about advanced spreadsheet, that passes way over my head...

1 each 12110113
1 each 12110115
2 each 12045889-B
2 each 12045890

Pins 12146448

The spreadsheet is for tuning / correcting the chip programming, we can post a thread later when it comes time to tune.

Hey Dave,

I don't see 12110114 in the parts list; when I click on the second item in your list above, it comes up as 12110115 and not 12110114. Just checking to make sure I get the right parts before I put in my order.

Thanks for the amounts to order.

The correct part is 12110115.

I've corrected my previous post.
