i got a thing in the mail i post it later what it is it will program you h3 and you have a palmpilot high tech but not $900.

 

The problem with programming it yourself is what fields in the PCM do you change do you have a High speed lamda sensor to monitor air-fuel do you have a dyno to test it. Commuicating with the PCM is just half the battle. Knowing what to chance once you have the key to the kingdon is just as important.

 

I have one for my mustang it works great had for two years now you can do many thing with it on the h3 hope the same

 

Perfomance products sells this.
Unichip flux power display
plug&play 5-9 power increase pockert pc and bluetooth
capture 0-60 times ,horsepower&torque
anti-theft immobilizer
$887.95 WITH OUT SOFTWARE [:'(]

 

If that's "5-9" horsepower, then it equates to an average of $138 per horsepower. Rip off.
