HPT..... Anyone?

I also read somewhere that HPT cannot tune unless you are running the stock tune... does anyone know if thats correct?

FYI if you are 07+ you are lucky.....

They are refusing support for the 06 models like me, if they do decide to support the E16A ECU then it will be another year til it gets released

They haven't been willing to support the older L61 for years, they aren't gonna start now. Too small of a market to make it worthwhile for them.

Did you do your own tuning? Is it true that you need to be on stock tune to tune with hpt?

They have been saying "next year" since 06. They arent going to cover us. Trifecta or piggyback are the ways to go with us. That is why I I bought an 88 RX7, more tunability since I am gonna go carb'd on it.

Yes you must go to your stock tune, Hpt can not write over trifecta.

I have been hp tuned for well over a year now. First on my NA setup, put 150 whp on mustang dyno, and now on my turbo, built motor, put down 319whp on mustang dyno at only 14 psi. Both of my tuners are in Chicago, PWerks and blackbaltsw both great.

hahahahahahaahahahahaahahahahaahahahahahahahahahah ahahahahahahahahahahahahahaahahahahahahahahahahaha hahahahahahahahaha. You have about the same tuneability on the stock computer in your cobalt as you do with a carb, as long as you dont mind buying custom sized injectors and running some interesting fuel pressure regulators. If you put a carb and not a stand alone on whatever rotary or v8 that is in that rx7 I'll come to your house and do dirty things to you that you wont like.

thats not true. the turn of a screw and change out the jets. thats all you need with a carb. but then again i dont know too much about rotarys. i know everything about carbs tho.

exactly, just that changing from a 24lb injector to a 25.3 lb injector costs a bit more than a bigger jet. But put a haltech or AEM in that thing and you'll be a lot happier with a car that actually starts most of the time.
