Go the Uprev website, then support section, there is a "Cipher User Guide" (cipher is for datalogging) and "Osiris User Guide" (osiris is for actually flashing your ECU). It has a set of parameters there as well as other instructions (basically, just read both!). You should do at least 2 good 0-60 runs (using the performance logging option) and then some regular cruising, that should give the Uprev guys enough info.

In case you need the parameters though:

**Verify your ECU is added to the AFR conversion. See Cipher user guide**

By the way, even without flashing the ecu, Cipher allows you to reset your ECU (the real way, not that pedal pressing thing that people talk about), so it unlearns your grandma driving style (or at least mine was apparently, b/c when I reset it, I could definitely tell the car was more responsive). Although I've been having some fun with the datalogging, I'm still waiting for Uprev to crack my ECU b/c apparently I have a very new one they haven't encountered yet.....hopefully it comes soon!

 

if they have around the same gains, how come I have not seen a tune via uprev crack 300whp.
yet using cobb my 1st dyno tune pulled 325whp on a dynojet.

 

Whiddles , go get it done, that little device can make your damn YEAR! Check Cobb site, they'll point you to know tuners in your area.

Cobb tune should run you between $350-$600, all depends on the tuner.. Mine was $450 and the best mod to date. See:https://www.myg37.com/forums/2931969-post1.html.

For the OP, have you checked below for an Uprev tune:

Performance Motorsport East, Inc.
530 C Middle Country Rd.
Smithtown, NY 11787

I'm rather incline to believe it's the tuner..after all the tuning software is just a tool, it's the knowledge and experience using the tool that can make the difference. Then again Dyno's can be made to read what they like.. the only real reference I consider is the before and after comparison for gains.. and of course my Butt afterward which should confirm it..lol.
