Ive just upgraded the turbo on me 1kzte diesel truck which i use to tow the racecar around b16a2t ef9

I need to tune the thing to get more fuel, diesel tuning principles are more fuel = more power to put it crudely


But my ecu has no map or afm. Afaik it uses RPM and TPS to calculate the fueling.

So do you think it would work if i spliced the TPS signal into 2 wires, put one to the TPS input into the SAFC , and the other signal into the MAP sensor input, then run the MAP sensor out signal back into the ECU's TPS. Only thing is will the SAFC recognisse the TPS's signal, as theyre both 0-5volts, but is there anything different about them?

Thanks
