Hellor everyone, i am very new to the hp tuners world, i had a friend of mine, also new to tuning, unlock my pcm and program the efans for me, while in there we turned off the egr and knock sensors, i still have the MIL light showing the codes for them.. is there another step i need to take to shut off the MIL light ?
The truck is a 2001 chevrolet silverado 1500 5.3
The codes must be set to no error reported. If they didn't do that, then they will have to change it.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
This. I've seen new users just uncheck the SES enable box thinking that's all you have to do and it isn't.Originally Posted by 5FDP
as of today Dec 28,2022 I tried to do that but it doesn't want to change it the a bug or did hp tuner change that setting
