They're the actual revisions/tunes that Diablo puts out ... my car ran best on the original r18 tune ... it used to chirp the front tires at times .... never had that kind of off-the-line power ever since, even now with heads/cam/headers/whatever else I had done ...
Ok, thanks. So, what do I need the USB cable interface for?
The USB cable is helpful if you want to do datalogging on the Predator. You'll either want to connect the Predator to a laptop in the car to do extended logging (the memory on the Predator doesn't give you much time) or, if you do log directly on the Predator, the cable lets you download the log to your PC for better analysis.
I also like saving my stock tune from the Predator to my PC, just in case I need it for any reason.
I haven't ran but only one crom the 21 but I have an '08( no VCT), is there a better one to run? I remember the posts of ppl switching croms on the '06-'07 model LX's and noticing a difference at the track and some using the butt dyno!!
Honeycomb insert with heritage R/T emblem, BT Pistolgrip, Demolded, lots of parts painted TorRed and metalflake silver, a GSM CAI( off car now) , chilly air mods, and an AFe gone to research!
the newer 21crom for the 09s and 10s is really great. much improved from the r20. just wondering why diablo deleted the option to turn off the egr.
I think they did this to keep the EPA off their back. Disabling the EGR is essentially tampering with federally regulated emissions equipment. If they keep their software clean less chance that anyone is going to hassle them about it. They did leave the ability for custom tunes to disable EGR but their canned tunes don't touch EGR anymore.
