Switched ecu, TPS question.

[kas14slider]

Hi guys, I recently got an eformance tuned s13 ecu for my s14. I fire up the car and it runs super pig rich. I start checking things and notice that my SAFC II is reading %58 instead of %100 throttle when I have the pedal pressed all the way. And also, on safc sensor check, the volt readings are way too low. After running rich for a while my plugs are covered in fuel and car doesn't start anymore. But I plug in my stock s14 ecu and I check out the safc and now it reads %100 throttle when floored and the volt readouts are correct. I don't want to start up the car thought because I upgraded to 550cc injectors and the car will run way too rich anyway without the tuned ecu in there. So I was wondering, do you guys know if I have to switch to a TPS out of an s13 for it to work with the OBDI s13 ecu?
