1982-1992 ECM Schematics
Does anyone know if schematics are available for any of our ECU's? And where can we get them?

Excellent, thanks!
I currently have the 1227165 ECM and a Moates Autoprom programmer. After I get the OBX Racers long tube headers on, I plan on playing with TunerPro RT...
Would you see any advantage to try to overclock the stock ECM? I see it's a pretty exact frequency of 8.388 MHz. Might have something to do with those MISO/MOSI lines? Also, it's got TxD, RxD. More serial comm.
Here's a link comparing TxD/RxD to MOSI/MISO/SCLK for those unfamiliar...

Also, when I click on the link you provided (for the 1227730 ECM which I plan to use in the future with your P4), in the internet bar of the browser pops up this: http://www.exatorq.com/ludis_obd1/1227749schematic.html
Are the 1227730 and 1227749 identical or is there an error somewhere?

You might find an aftermarket ECU more appealing.
A lot has changed over the years.
