hi im now going to change my engine from the c20xe red top to the c20let turbo engine. i just need to know if i can use my mbe 956 ecu to run it or will i need a new ecu. the ecu is running gsxr throttle boddies with tps ,coolant temp and crank pick up sensors

would have thought the ecu needs to have a MAF sensor input also

Definitely will not run on the 956.You could maintain the tb`s and build a plenum for it, they will save u some room under the hood.I considered it my self but its quite a job to do apparently.
