Hello everyoneI My first post. Currently, I am MegaSquirting a 1986 Toyota Mini Cruiser. Essentially, a 1985 Pickup with the 22RE in it, and a serious overweight issue, LOL! LONGGG time MS user with more than a few installs under my belt. Many more. Working on a Miata project and I came across some interesting boards. No surprise that many of those led me here to Speeduino.
But imagine my surprise tonight when I was reading through stuff here tonight and saw what looked like my donor Toyota ECU sitting next to one of the speeding boards. Closer examination revealed a few minor component differences, but the MK1 Mazda miata and my 22RE board. I had to go back out into the workshop and grab a spare Mazda ECU, and sure enough, REALLY close. I still had the brackets on and hadn't realized just how close they were.
I haven't looked into the ignition input circuits yet to see how compatible they are. Most of the Toyota VAST info out there is actually pretty outdated to begin with. So this might not be a simple open and compare. But both the OEM ECUs for the Toyota and Mazda appear to be pretty similar inside...
The Toyota uses a Nippon Denso 42 pin connector. Well three actually. 10p 18p and 14p.
There are some other interesting things I discovered. Speeduino boards are apparently pin compatible with MS3 Pro modules. AND anyone knowing the price of one of those already knows why I am now here...
