will an el ecu (preferably XR6) plug straight into an ED. if not are there any that are interchangable with this model car. thank-you

You'll lose your trip computer I think, and I don't think EL's run as much timing from Idle to about 3700 as EA-ED ECU's because of the BBM - so you may (or may not) lose a little bit of bottom end.
But to answer you question, yeah it'll plug straight in and work no worries.

Yes, the EL ECU will plug straight into an ED and it will run no problems - BUT the EL ECU is designed specifically to work with the BroadBand Manifold. I don't know for sure if there's some sort of fault mode it will go into if it detects absence of BBM and Knock Sensor (ie. that results in reduced performance) but I know for certain that compared to a proper ED ECU the engine will feel down on power - at least that's what I found.

Feel free to try it - you won't damage anything - as I said, the EL ECU will plug right in and the engine will function fine - you'll just have to determine whether it's any better than the original ED ECU.

thanks for that, i dont really have the cash for experimentng it was just a thought as i may have to replace my existing ecu as it may not be working correctly. thanks again
