AlexSavv Posted September 17, 2018 Report Share Posted September 17, 2018 Hey guys, wondering if anyone knows if the G4+ models act as voltage regulators? Upgrading my alternator to one that doesn’t have a built in voltage regulator, I believe this is because it’s designed to be regulated by the ECU wondering if I will blow anything up or does the G4+ platform regulate it for me? Thanks Al Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 18, 2018 Report Share Posted September 18, 2018 Hi Alex, We dont have any built in alternator control strategies. Some you can control with a PWM table but you need to know what sort of signal the Alternator is expecting. Also some "ecu controlled" alternators still work fine without any control signal - they just output max voltage full time. Quote Link to comment Share on other sites More sharing options...
AlexSavv Posted September 18, 2018 Author Report Share Posted September 18, 2018 Thanks for the reply! Ah cool, just wanted to know if having an unregulated alternator can damage the ecu, injectors, coils etc? I guess it is a broader question as opposed to specific to Link Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted September 18, 2018 Report Share Posted September 18, 2018 What kind of vehicle is this? Is the alternator just have no regulator inside or is it something that is expecting ECU signal to command a specific output? You will need some form of regulator.

Sven Posted December 9, 2019 Report Share Posted December 9, 2019 Has anybody managed to crack this one yet, I'm having the same problem with a 2016 mazda alternator? Quote Link to comment Share on other sites More sharing options...
Richard Hill Posted December 9, 2019 Report Share Posted December 9, 2019 We had a similar issue with an rx8 running a fury, the alternator voltage went up very high (and damaged the ecu). I didn't have easy access to the bike otherwise I would have worked out an ecu control strategy, so we got the owner to convert to an rx7 alternator which I believe was a direct swap. HTH, Richard.
