Hi all, a friend of mine as just bought an ECU from the '08 Exige cup 240 for his '06 Exige S 220.

He told me this morning after install the new ECU, the motor has some trouble and the STACK doesn’t respond… no Miles, no rpm, noting but the car works…

Do you have any idea ?

For info, he didn’t already install the big injector (don’t know if it’s realy needed or if it’s the raison of the motor trouble)

Thanks for you help

I am guessing its the one off ebay? I am no mechanic but trying to run the car without the correct injectors sounds like a good way to do some damage to it. The 240 ecu is calibrated to the high flow injectors and there is no way I would run it without those fitted.

I belive the 08 black ‘stacks’ run a different canbus to the earlier cars with the white instruments, Im guessing you would need a later stack. There was one on ebay reently, I think there may be one in seloc classifieds.

Do you really mean cup 240? I was not aware of these…
If it is a PP 240 then you need to change the injectors as well, you would be better off selling the ECU and getting a Gotham from Sinclair might be more expensive but a hang site less issues and more power :wink:

I would not run the car.

As others have said, you will be in danger of running lean / wrong duty cycles, and that will mean bye bye engine quite quckly.

Gotham is the best way - i’m still really pleased with mine.

Thats a good point, did not think of that. As others have said by the time you have fitted injectors and a new stack you may as well of had a Gotham tune. The only suggestion I could make is if you get on well with your dealer seeing if they could flash the ecu to run the older stack but I am not sure if thats possible. You’ll still need the green injectors tho otherwise as Mark says engine life will no doubt be short.
