Which ones are out there? Predator doesn't make for my year, ls1edit is too much money and HPP3 I heard is not a good programmer. Help me out please.

 

I have a HPP3 for my '99 , and am happy w/ it - it was one of the mods that came w/ the car.


But, it is not a true programmer per se - it will allow you to add the power programming, change fan settings (in preset increments, not infinitely) , adjust for different tire heights & rear axle ratios, and alter shift points & firmness (A4 cars) .

For my car - w/ stock cam, intake, a cat-back, and some free mods - that's all I need, and seat of the pants feel tells me the HPP3 works.


Other will have different opinions - welcome to the World Wide Web !

If you anticipate "heavy mods" - Heads & cam, etc. then I would bypass this and go for something like an LS1 edit that I understand (no direct experience w/) is far more versatile.

The Hypertech programmers aren't really worth buying. If you really need something done then I would get it tuned.

 

of course...the HPP3 tuning advances timing....big no-no for spray...


hypertech IS worth the money if u have an auto car....shift firmness comes into play with a stall converter, shift points and rev limiter can be altered and my car now runs no hotter than 185 on the stock 195 degree thermostat.....on an M6 i wouldnt bother unless u do alot of gear changes or something...look for a used one somewhere.....they go for as low as a hndred bucks.

 

Wouldn't it be a good idea to change to a 180 thermostat? Fans may work less.

 

yea its definitely a good idea...unfortunately i never get around to it....lol

see him for custom programming it will be better then buying a programmer if you continue to mod

 

180 thermo may open sooner, but the fans won't kick on until the stock setting of like 217 for # 1, and 228 for # 2.

So, you are still running just as hot & the fans are working just as much.

all i know is i optimized the cooling for the stock 195 thermo and the car runs A LOT cooler...im pretty happy with it this way...
