tps comparisons

having had a night mare trying to get my car running on an e8 4 plug ecu ive given up and plugged the old 6 ecu back in, re pinned it ect ect. reason for the ecu swap was to run sd, the e8 ecu was mapped, converted ect to run sd. anyway i thought id try running the car up at idle with the maf unplugged, map/iat sensor hooked up as per sd but on the standard e6 ecu and to my suprise it ran and idled reasonably well. the car is an evo 4, with a e8 engine and i never thought to consider where the inlet/tps and ancilleries came from. i have a hunch the reason the e8 ecu would justflood the engine and run on 2 or 3 cylinders could be down to the tps. i know some tps have a 3 or 4 pin plug. is the difference between an e4 tps different enough from an e8 tps to cause major running problems?

Tps is not the problem. What injectors does the 8 ecu have set to?
