Well Guys I just Got Back From Super Chip Tuning I was On The Coarse To Learn How To Tune Using A Laptop I also Own A H2 2003 The biggest problem is that each vechicle is different & on the 2003 ecm is different than the ecm on the 2004 H2 And Up..But i found that i could tune my 2003 using the super chip tuner..This tuner works on the 2003 only ...After the tune i could get into the computor & change a few things but not all..Anyway with the new programers we can tune all h2s..All we need is your Vin # that allows us to get into the ecm..I will be working on custom tunes in the next while for the h2s .WE can than program them into the sct programer & will be able to offer custom tunes for the h2s...If you want to read more check it out at sctflash.com

The reason we are doing this as we need to custom tune them to except our hydrogen generator..If we add hydrogen the ecm thinks we are running lean & dumps more fuel in..So we have to tune it to except 91 octane
