Peszczyn1 Posted January 3, 2020 Report Share Posted January 3, 2020 Was doing some tuning and it was recommended to upgrade the software from 4.9 to 4.10 and I did that and then as soon as I started it dash was dim and when you rev it voltage drops and starts revving up and down by itself until it dies . If I hook a battery up sled runs fine and lights are nice and bright . No voltage issues right before software update and as soon as I did this update the very first time starting it after this update is when It did this so my question is with the update is there any settings or values or triggers that could have changed or need to be recalibrated or anything like that ?

Ducie54 Posted January 3, 2020 Report Share Posted January 3, 2020 Always recommended to do a file compare after software upgrades to see any possible changes. Quote Link to comment Share on other sites More sharing options...
