Looks like the DME/ECU #172 does work on a M20B25 as well. I was chatting to a mechanic and he showed me a car that did the conversion from M20B20 to B25 and using the 172 ECU without any problems.
I'm just curious does that mean the 2.5 engine is running lean since its using the 2.0 mappings with that ECU?. Any long term implications on the engine like more wear and tear, running hotter, less BHP, etc.
Anyway I believe the 172 & 173 DME circuit board is the same, the only diff is the main chip in the DME itself. If you get a 172 DME you can plug in the 173 chip and it should still work. Well theoritically anyway.... B)
