OK I've now taken the ECU off the car and as I suspected the EDIS unit has been built into the case and hard soldered directly to the board so it can't be disconnected easily. I tried the car again yesterday and it started perfectly and we warmed it through thoroughly before putting any load on and ...

I need to work out how to disonnect the MJ so that I can run it on Limp-Home edis only but the unit was supplied built with the edis unit in the case. I guess it's time to open the case and get my fingers dirty. When reading the timing with the gun it was pretty steady. When the problem occurs it se...

My 1000cc full race Imp engine (rev limit 9000rpm) has being running fine with MJ for 12 months but last weekend while away at an event it started playing up. If the engine is completely cold it starts and runs fine but after a minute or so it won't rev properly and loses power. It get's so bad it c...

Thanks Martin. You've pretty much confirmed my own thoughts but I'm still not sure whether the TPS loads sites should be linear or closer towards the bottom end. I'd assumed the 78% top site was based on rolling road experience that indicated there was little difference between 78% and 100% throttle...

I've been lucky enough to get hold of maps for other cars with identical engine specs to mine but they all seem to have 16 load and 16 rev bins so I am having to try and pick what load values/rev values to use. With the load values for the TPS I notice that many others seem to have several load site...

Thanks Brent.
It's version 3.2.0. although the bit about the square wave and duty cycle is too technical for me! If I can run the tacho on 2 cylinder mode do I need any kind of resistor in line or will that be trial and error?

O.k. no surprise that my Tacho doesn't work on my newly installed set up. Everything else is fine but the Tacho output doesn't drive my Stack Tacho. Having spent hours reading all the threads I could find I seem to have reached the conclusion that it needs running off the negative side of the coil b...
