Added the scan file. Not sure what is best driving wise, when scanning. So I cruised down the highway for a little in fifth gear, got back on and did a pull.

Can't believe I did that. I'll go get a scan in a few minutes, but I attached the tune.

I'm trying to learn how to tune, not having too much progress. I'm using a ZZP tune right now, so its not great. Having some issues I'm not sure what to do about.

Sometimes I'm getting full boost,...

I played with a few things and I think I got it working. Device manager now shows under the Universal Serial Bus Controllers HP Tuners MPVI Challen A, and B.


Thanks so much for the quick replies...

No, That is what confuses me. It acts as if laptop doesn't even notice it being plugged in, but it gets power.

Yes it does

3)Connect your MPVI interface to your laptop
4)At this point the driver install will likely fail(it did for me)

^Windows doesn't detect the MPVI interface and doesn't attempt to download any...

Haven't been able to find a basic TVS tune I can start with, I've been running a tune I played with myself, car seems to run ok..
Don't have money to get car professionally tuned or I would.

If...
