Someone has screwed the wiring up then...
Well it has been perfect for 4 years so if the wiring was screwed, it would've shown before now!!
What I meant was that the LPG injectors should correspond with the petrol ones... That they don't muddies the water, but could suggest an issue with the LPG ecu or loom
That depends on the wiring loom you get with the ECU. Often the grouping of the wires means that you can't follow the cylinder numbers accurately. It doesn't matter to the LPG ECU as all the injector channels are identical.
Yay, I've been waiting for the expert!! So by that reasoning, when the software reads 0.0 for tb4 and tg4 does that mean that the lpg refers to the petrol injectors by the lpg injector number? Because lpg injector 4 sits on cylinder 3 and there was a number 3 tag on the petrol injector that supplies cylinder 3.
When following the wires the lpg injector for cylinder 3 is not wired to the petrol injector for cylinder 3.
Yet it says tb4 / tg4 not working. I am so confused!!!!
