Sterling Posted April 21, 2021 Report Share Posted April 21, 2021 G4+ ECU, lambda seems to be accurate on laptop when I live steam the ecu, but shows inaccurate on the dash For example, will show 12.5AFR on laptop and read about 8.5AFR on dash. Won’t have time to play with it for a day or two, but wasn’t able to fix this problem after a few tries Everything else is working properly, Dyno tune tomorrow afternoon Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 21, 2021 Report Share Posted April 21, 2021 Do they show the same Lambda values? what Stoichiometric ratio are you using on the ECU? Quote Link to comment Share on other sites More sharing options...
Sterling Posted April 21, 2021 Author Report Share Posted April 21, 2021 I don’t know how to check what ratio is being used on the ecu Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 21, 2021 Report Share Posted April 21, 2021 The reason I ask is because the value is transmitted as Lambda and so differences at each end could be due to one end using a different stoich value. Quote Link to comment Share on other sites More sharing options...
Sterling Posted April 22, 2021 Author Report Share Posted April 22, 2021 My tuner sorted it out for me today with a math channel calculation in the dash. Quote Link to comment Share on other sites More sharing options...
