Fotis Posted April 20, 2019 Report Share Posted April 20, 2019 Hi guys ,which is the correct way of wiring link ecu as piggyback? Spliting the signals from the factory ecu to the piggyback or cutting the connection between the factory ecu and connecting the needed wires directly to the piggyback?. Thanks.

Stevieturbo Posted April 20, 2019 Report Share Posted April 20, 2019 Depends on vehicle, which sensors/actuators, wiring, and what you're trying to achieve. Quote Link to comment Share on other sites More sharing options...
Fotis Posted April 20, 2019 Author Report Share Posted April 20, 2019 So how i know? What about triggers,map sensor,tps? Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted April 21, 2019 Report Share Posted April 21, 2019 It's up to you to decide based on whatever it is you're trying to achieve, and what you want each ecu to do, or how active/functional you need the OEM ecu to remain. In general, 2 wire sensors/triggers cannot be shared 3 wire powered sensors can usually share a signal. k fuku 1 Quote Link to comment Share on other sites More sharing options...
