I’ve been procrastinating on tuning software sense purchasing a supercharger. Just can’t choose between SCT and HP. I read SCT is limited now by EPA overreach and won’t allow a full race tune (no cats) and that HP is more difficult to learn.
I have full access with SCT, dont believe the hype. You take a 20 min open book test and you are all set. You sign a form that you will not disable emission shit for a street driven vehicle.
SCT is the only tuning software that is emission testing friendly (if that matters)
As you can see from my post, I find it a bit 'scetchy'. I have had to flash the same tune twice on a few occasions.
If you own an x4, its a no brainer, sct.
If you dont have a tuner device, price is about the same for both.
HP will work the same. But they have not been targeted by the EPA yet.
I find pretty much all tuning software laid out very similiar. I have used TunerPro to tune my 91. Interface is practically identical IMO.
I also had Syked tuning hardware software, same basic interface, but Kevin could not get it to work on my swap. Did not have support for the Control pac strategy, so I was left with a no crank/no start condition.
I have two theories on the file size funkiness.
1 I entered a value in a field that it does not like. Some values change slightly when moving to next field.
2 some areas of the tune when changed, cause this additional file size change.
Not sure yet on this
