The last time I asked DiabloSport about the tuning for 2015's (last Fall), they said it would work with the current Tuner/Trinity devices. I guess you just got to ask yourself if you sell your Trinity now, will you be able to buy one for the same price or less later? That's assuming the information about being the same device is still accurate.
One thing I know is that I don't wish to be an early adopter of the new 2015 tunes until the wrinkles are ironed out.
I contacted HPtuners today and they have cracked it but not the transmission yet. They told me it would be $250 and send my ECU in. Then have to get it tuned. Going to wait a little longer and see what other manufacturers come up with.
A forum vendor was wanting a 2015 test vehicle for a Maggie install, no PCM swap, so apparently they've figured something out, can't wait to see the results,
If another vendor wants a test vehicle sign me up. I have a 15 scat pack. Sitting in my office at work I've got and edelbrock Eforce, longtubes, zoomers catback on the way and about to order drop in Pistons,rods, and maybe a cam sometime this week. Also have some nitto NT05r on the table. Can't keep all this at home, the women would be pisseddddddd.
Just completed two 2015 supercharger tunes. We still learn something with every new one, but the answer to "is it cracked" is yes. Both HP Tuners and Diablo have the ability to modify PCMs to be able to be tuned with the current Trinity. You do have to have a physical mod to the PCM or swap for a modified one. We can do that for you.
I got a scat pack running a d1sc @11lb with mm ported heads mm ported tbody, mm custom blower cam, lontubes, zoomers, mm drop in rods and Pistons, fore fuel system, tons on driveline mods, and some other crap I can't remember. Tuned and built by dtp outa va beach using hp tuners. Cars going back this week for a pulley swap, more boost, and a retune. Oh...and all this was done months ago, so tuning is g2g
