My son has a 2006 LBZ w/dps5 and it won't let me remove and modify the tune. Is deleting and putting a stock tune in my only option or has someone found a way around this yet ? If I need a tune for it where can I get stock or a good mild tune.
His tune the check engine light stays on all the time for coolant temp issue. I wanted to go in and either change what it's looking for or make the fault not light the light, it runs awesome.
There is no way around it, a DSP5 tune cannot be read out because the maps are stored outside the area the ECM allows reading from so reading is blocked.
You will need to obtain a stock tune if you wanted to tune around the issue......or fix the coolant temp issue rather than tune around it.
Cheers,

That's what I told him to do. The guy he bought it from a couple years ago said that with the tune that was in it that they ran 160 stats to keep it cool to make more power. Sounds like he just didn't want to replace the stuck stats either.Quote:

Thanks everyone
