yes you can use another used ECU and immobilizer swap file, that has a central processor st10 vc copies banks 1 and 2 for the immobilizer
55 reg, 1.4 petrol, problem is on startup revs stop at 1500rpm. plugged in diag, faults are map sensor, in live data shows 0, changed map still the same, done pinouts to ecu all wiring fine. i have checked voltage at map sensor according to autodata. it says there is a 5v, gnd, 4v. i am missing the 4v so i suspect ecu fault, can i use second hand ecu or does it have to be new, numbers on it : iaw 6lp2.05. thanks

Hi
Have you checked if there is no any leak in Intake System...
Thanks Ash
Oh yes if my post was helpful than Please don't forget to press the Magic word Thanks
Id image the 4v is a signal from map sensor to ecu???,
So replacing ecu, wont fix, as youve changed map sensor, check for air leaks as ashraf says. if all good cut wire coming out of map sensor and test voltage again, as wire to ecu may be down to ground in loom????

a bit of feedback, i disconnect camshaft sensor and voltage then was right at map sensor, 5v, 4v, gnd. problem was the camshaft sensor, its on the same line as the map sensor 5v. it was shorting out therefore bringing the voltage down on map sensor. the camshaft sensor is located behind air filter box coming off throttle body. thanks for all help.
