Use 90-93 MS on my 95M
 

I have a 9093 v1.3 Megasquirt.
Is it possible to modify this to use with my 95M?

Any suggestions? I'm new to boosting so thank you for your constructive comments!

Need more info then that. Post a picture of what it looks like and we can tell you.

nope, that's the main reason you should not buy model specific ecu's

Unplug the battery and see if the 95 wiring harness even plugs into the ecu. If it does, you're in luck, if not I'd find a new ecu.

If they fit, open up the connectors, carefully remove the pins, and make them match this:

Those diagrams were from way back when we had incredibly basic MS1s, but luckily that's what you bought. It's a very capable ecu, however you'll have to make the mods to use your VTPS, and I think the pre-OBD2 95s (which I think yours is) were still batch fire. If not you'll have to bridge injectors 3 and 2 with 1 and 4 respectively.

Won't work with a 95M, only with a non-m version.

Sell it and get the correct one for your chassis. There is to much work involved for you to try to make it work. Not worth the time or the effort for a MS1.
