Grant Baker Posted May 25, 2019 Report Share Posted May 25, 2019 Hi Got an EVO here with a ViPeC plug in (V series). All was fine and then suddenly on an acceleration ramp test, the rev limit did not activate, and hasn't activated since! Nothing was changed in the tune except some minor fuel tweaks! Any ideas?

Adamw Posted May 25, 2019 Report Share Posted May 25, 2019 In the V series and old G4 ecu's a fuel cut limiter wont work if your injector duty cycle is above 100%. So you either need to fix the fuel system or change to ignition cut. Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted May 25, 2019 Author Report Share Posted May 25, 2019 That makes perfect sense now. Bit weird that it allows you to over rev despite injector DC being over 100% though!! I assume this is not something that will be fixed and updated? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 25, 2019 Report Share Posted May 25, 2019 Development on the V series stopped somewhere around 2013. This bug was discovered sometime after that. It was fixed in G4+ but is something you will have to live with in the V series. I would not be running any car/ecu with inj DC above 90% having said that.
