3500cc Posted January 11, 2016 Report Share Posted January 11, 2016 I have a 2010 California-shipped 3.5 v6 Edge. I'm thinking of getting a standard SCT Tuner for it, but they will not ship it to California. I can get it shipped to an out-of-state address and then fetch it from there, but I still have concerns. Meaning, is there part of our vehicles' VIN that indicates it was a made-for-California vehicle? If so, will the SCT Tuner detect that VIN indicator and not work therefore? I just hate like hell to pay near $400 for a damned part that probably costs $25 to manufacture and then have the thing not work. Please reply. Thank you.

3500cc Posted April 19, 2016 Author Report Share Posted April 19, 2016 I'm replying to my own post. Got the sct4 tuner and installed the default tune into my California vehicle with no ill effects. I need to tweak it because the default tune only seems to fool the TPS and quicken/stiffen the upshifts in normal and full throttle driving. At this point, I don't feel any hp increase, and the fooled TPS makes you think the torque increased during normal driving, but full-throttle runs tells you otherwise. I'll reserve judgment until I exhaust all my tuning options. I think the device is not as friendly as it could be, but that's just my opinion. Others may think otherwise.

enigma-2 Posted April 20, 2016 Report Share Posted April 20, 2016 Do you have to have your smog level tested on an annual basis (leading to modifying the tune changing and take the emissions settings out of the acceptable envelope)? Quote Link to comment Share on other sites More sharing options...
Waldo Posted April 20, 2016 Report Share Posted April 20, 2016 Are you running premium fuel? The only way a tune is really going to make a noticeable difference in WOT performance is if it more aggressively takes advantage of premium fuel. On regular fuel the factory tune is already pretty well optimized. Quote Link to comment Share on other sites More sharing options...
sman83 Posted May 14, 2016 Report Share Posted May 14, 2016 I'm curious about this to. Although I am pretty happy with the sport mode and I only use 91 octane in CA. Quote Link to comment Share on other sites More sharing options...
3500cc Posted May 16, 2016 Author Report Share Posted May 16, 2016 More findings... Sct4 is user-friendly once u get used to it; Waldo is exactly right - the stock tune is optimized for 87-octane; I think 87-octane in CA is about 86-octane. I say this because the 87-octane tune seems slightly better with 89 pump octane. Meaning, I think what sells her as 89 is really 88 - total guess; The 91-octane tune with CA 91-octane pump gas is nice. Clear boost over the 87 octane tune; I'd guess if sman83 ran 89 octane CA gas, it would be just as good with his factory tune; about 1/2 of an mpg gain with 91-octane tune. I may now go back and tinker with my intake some more. Maybe with the tune, I can get more out of it. Quote Link to comment Share on other sites More sharing options...
