IS ecu into an E?

[87_325e]

i just got a great deal on an ecu from an 87 325is will it work on my 87 325e? are there any advantages if it does work?

I would be surprised if it ran properly but if it did you wouldnt really be achieving much. Maybe raise the rev limit? (assuming your 'e' doesnt have the distributor on the side)
The 'e' motors have smaller ports - intake and exhaust - and different internals, the head just cant cope with revving. Its a 2.7lt with low down torque in mind.
I would save that ECU and try also get your hands on a 323i or 325i head to bolt onto your 'e' bottom end.. get different pistons and you have yourself a hot little 2.7lt stroker with a 7k rev limit. Either that or leave the pistons as they are and supercharge or turbo it. Depends what you want at the end of the day really...

after posting the question i pulled my ecu and tryed to plug the is into it and its a diffrent conector. is there away around that?

[Scarecrow]

There is, and i hope your really good at wiring... It is possible to splice an 'is' connector onto it but it would be hugely time consuming and again your performance gains - if any - will be minimal. There is better places to be spending your time and money on the 325e...

ok i figured that was the case cause i dont want to screw with any wiring and was hoping there was an adapter plug or something like that. so im probably gunna ether hang on to that ecu or just sell it.
