Yes, but be aware that you would need the correct ECU controlled distributor to go with it and most likely the harness, and possibly other sensors.
I worked with a tuner from Holland to help him tune his Mk1 g13b-powered Locost, and he found that while the later ECU will plug directly in to the connectors, it will not run the car without, at minimum, swapping some pins. It might be doable, but you'd have to look carefully at the MK2/3 pinout. I
think that's available somewhere, but it might require some digging and be aware that it is another project.
The mk1 chip is fairly easy to find, however. It's the one at the top left in the photo that has the sticker reading: EPI OO16, or similar.
The tuner that I worked with did not share his final results with me, which is disappointing, but I did find the fuel maps, and ...likely... the rev limiter for him. The main issue is that there are 8 fuel maps :o and it's unclear whether the ECU switches between them or if so, under what circumstances it switches. You should be able to use the Ostrich to figure this out, but there's no way to know from the code, and again, my Dutch friend did not share. If it works, I've attached the Mk1 .bin and ECU definition suitable for use in Tunerpro as a .zip archive. This definition does not include the rev limiter, but if you go that route I'll share what I think will work to alter it.
