help needed i am in the process of building a c20xe with gsxr 600 tbs and mbe engine management but i cant get it to run ive checked the ecu (thanks to ns dev hes a saint) it runs ok on his car but not on mine ive checked the wireing again and again but cant find any thing wrong the injectors dont seem to be opening after ign is switched on the only diffrence is that im useing the original tps from the gsxr i dont know if this is compatatible with the mbe set up can anyone shed any light pleeeeeeeeease

I used GSXR 750 TPS with my Omex based setup and it worked fine. I did make the numpty mistake of thinking that the ecu provided switched power (not switched earths) to injectors and gave them all an earth. Ditto the fuel pump relay. Churned the engine over for an hour or two with with no fuel pressure and inactive injectors before I had that 'Doh!' moment and wired in ignition live wires to them.
Will dig out TPS pic. Also VR sensor is polarity sensitive. Does the lappy show you are getting a signal. If not might just need to swop VR wires.
