Good evening Gentlemen,
The ECU in my VX220 turbo has failed to provide power to the no. 4 injector and a replacement ECU appears to be required. I sent the faulty unit to a specialist UK ECU repair shop but it was returned as beyond repair. They claim that the Z20LET OEM ECU is notoriously unreliable. Is this really the case? I can't find any complaints to this effect on the forum. I looked into replacing it with an after market Link ECU but was quoted upwards of $NZ 7K for the ECU, wiring, mapping from scratch and tuning, so that course of action appears to be out of the question. The fact that there is only a handful of VX's in NZ doesn't help. Any advice on how to proceed from here would be much appreciated.
