One more possibility: While updating my Garmin GPS, I found that it would not finish downloading, much like the Diablosport tool. I used a different Updater and got farther, but it told me that it lost communication with the device.
Long story short, the computer was shutting off the USB port to ...

This already helped me a ton. I adjusted my shift points last night, and it is much nicer. It runs smooth, and feels "stock", which is what I want. I'm going for economy in spite of lower gearing.

I have one shift (2-3) that is reluctant at moderate throttle, even though they were all adjusted by ...

PayPal They handle the foreign currency differences, and all that. Safe and secure. Add it to your existing website, and nobody will have to call you. Have a field where they provide the info you need. Once you receive payment, you send them an email with the info that THEY need.

there are no licenses for the intune i-1000.. it can not tune more than 1 vehicle at a time.. you can only tune 1 vehicle at a time with that one..

if the one you have is locked, you either have to restore the original backup stock tune to the previous vehicle first in order to unlock/reset it ...

I'm in the same boat. You would think there would be a tutorial on these tuners, but there isn't. They expect us consumers to all be data nerds or something. They would sell a whole lot more units if they actually made it understandable. They use so many acronyms instead of descriptions, yet there ...

Something like that ...

I ordered a serial to serial cable and connected the tool to my old PC that is still running Windows XP. It loaded the crom on the first try with that setup.

I still have no idea why it wouldn't work with the USB to Serial cable. Tried two different computers, two different cables, and ...

(Still here.... )

I found an old thread where a guy had a similar partial load problem when trying to transfer tunes to his PC. He was using a serial to serial cable. He used a different type of cable that his PC also had, and that worked.

I've ordered a serial to serial cable to try on my old PC ...

Well, I've gotten nowhere on my end. It looks like I have two choices: try about ninety nine more times, or send an RGA request form and (at least) ninety nine more dollars. I'm not content with either. I am in a no-win situation, and I sincerely regret buying this tuner. I don't even want to look ...
