BTW, that's not the only thing rotten on their website. Check out the LS1/LS6 dyno charts:

Notice how they manipulate the measurement points so that they come out in the best possible light. The normal benchmarks for comparison are average under-the-curve increase or peak difference. Making comparisons at some arbitrarily selected (by them) rpm is bogus.
Since you have a 2002 model, you can select from any of the other hand-helds or edit programs mentioned earlier in this thread. They are all better and more capable than the HPP3.

....It does say on the Web site it will program up to 3.73 gears....I bought this POS and now what....Has anyway had any luck calling Hypertech on this and getting a refund!!! They clearly advertise on their Website that the gear ratios are programmable from 2.73 - 4.10....
guys...guys...guys.
The HPIII is not just for Corvettes. It's for just about all GM vehicles with V8 engines... (not just Vettes).
The gear scaling function of the HPIII works for all cars, EXCEPT the C5. They didn't know it at the time, but the C5 is a unique animal in the GM platform. And their HPIII does not take that into consideration when it comes to gear scaling. It treats the C5 like it's an F-Boby in regards to gear scaling... and that is why it fails.
Their advertisements are partially correct. It would be nice if they listed an exclusion for the C5 in their ads. But maybe their thinking was that very few C5 owners with A4's would ever go to 3.42 (or more radical) gearing... so they thought they could "get away with it"
If you call the HyperTech people (and get through to someone that is truly knowledgeable) they will admit to the flaw when it's used on the C5. They have told me this myself. All you need is to mention the P1870 error and they will agree that "yes, it can't handle non-factory gear scaling on the C5 A4's"

Their advertisements are partially correct.

They have known about this issue for years, yet the only apparent change they have made on their website is to update it to include the newer model years (while retaining the blatantly misleading info). I mean, after all this time, how difficult is it to add a footnote saying "N/A for Corvettes"?

I called Hypertech this morning to discuss why they advertise on their Website as well as in the instruction manual that you can change Gear Ratio to non stock gears and they state on the web page it is correctable all the way up to a 4.10. It seems alot of Forum members have had the same problem....Do we have enough for a Law suit or Class Action....I mean this is False Advertising....Any members who are attorneys, feel free to chime in....Thanks John

Sorry, but I have to disagree. I think their advertisements are 100% wrong and misleading. They may not have known it at the time, but they certainly know it now.
I know of 2 people that telephoned Hypertech about this C5 A4 bug. Hypertech said (paraphrasing) "you'll need to buy someone elses product, and we won't issue you a refund".

Do yourself a favor and listen to Mike Mercury- he knows what he's talking about. If you have a stock transmission, don't leave the shiftpoints up all of the time, maybe just at the track.
