Wee Chia Yung Posted April 8, 2021 Author Report Share Posted April 8, 2021 Hmm I'm thinking using monsoon for tuning and factory ecu for other function Quote Link to comment Share on other sites More sharing options...

Adamw Posted April 11, 2021 Report Share Posted April 11, 2021 Injectors, coils, idle valve, vvt and vtec, can all be cut from factory ecu and connected to the Link. Crank, cam, ect, iat, MAP & TPS signal will have to be shared with both ecu's. All the sensors that are powerd by 5V are probably best left with the 5V and ground from the factory ecu and only the signal connected to Link. AC request and AC clutch will have to stay connected to factory ecu since I think that is controlled via multiplex. AC idle up will no longer work.
