Opinions on OBDII auto tuning software

[ERM Performance Tuning]

18 months ago my advice would have been buy hptuners and never look back. However there has been a number of changes to the software and specifically the licensing structure that has made it a less valuable tuning package. My advice would be if you want to tune one or two vehicles for personal use and sell the device hptuners is probably your most cost effective tool. If you want to do multiple vehicles, have a "tuning" shop, get into doing engine swaps and vin changing, buy EFI Live to start with.

As a new forum member, I am sure I will be late a few more times, but I would like to know why you think EFI Live would be a better pick, even for shop licenses. Lets start out by saying I use both software's and have for over 7 years. I like(d) both of them for various reasons but lately I have not been seeing the support from EFI Live relative to the new platforms (E92/78/39). the now older A6 trans and even less of the A8, non GM platforms (Dodge, Ford etc). Yes, HP Tuners left us in the lurches on VVE (thank you Phil Smith, Bluecat, for filling the void), but over the last 2 years, they have blown by Live on the A6 as well as A8 transmission, provided excellent capabilities to log and tune torque parameters to work the DI platforms and have extensive support for Dodge and Ford vehicles. I wouldn't even think about using anything else other than HP Tuners for A6 (full shift time/pressure tables, upshift torque management etc) or DI platforms such as the C7, Z06, ATS 3.6 etc.

Licensing is also a bit cheaper at $99.99 per vehicle vs $125

Lastly the release of 3.0 and now 3.2 has greatly improved an otherwise excellent product with a faster and more effective Scanner, expanded filtering and even now match the Live Serial WB interface as well as an AEM Can Bus interface developed by dr. Mike.

Yes the Vin changing is a hassel but they are very paranoid of "copying licensed files" from PCM to PCM :-)

All in all I would recommend HP Tuners at this point only because they are moving forward in their support of gas powered platforms across multiple vehicle platforms and continuimg their R&D. I mean just in the last 3 weeks they have released a means to adjust the dreaded P1516 REP as well as a fix to the stubborn-some E38 Rich after Flash.....

I'll get down now :-) sorry.....
