Bradwood Posted September 3, 2022 Author Report Share Posted September 3, 2022 For the st205 g4+ V2-3 ecu to work in the st185 V1. What pins needs to be switched around in order for it to work? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 4, 2022 Report Share Posted September 4, 2022 If you looked at the docs I linked it would be pretty clear. I have pasted copies below. All the highlighted ones would need to be moved. There are some other differences that can just be taken care of with software settings rather than wiring changes - for example Ign 4 would be connected to EGR rather than Inj 5, Aux 5 will become the CE light, An Volt 4 will change to MAP sensor. And then some will need both pin changes and software changes - for example aux 8 needs to be moved and it will become the TVIS control.
