I bought the Hypertec Power Programer III yesterday for 289.00 from my local speed shop. I have a 94 coupe and it let me lower the fan temp/raise the rev limiter and tighten up the shifts. I also installed a powerstat 160 degree thermostat. Wow :cool: it really tightned up my shifts and lower my temps alot, I was running in the high 220's now I'm in the 190's. I also did the bypass the throttle body mod. What does everyone else thing of the programer? Should I use the performance mode on the programer? Thanks. :cheers:

 

The programmer is good for what youve done already. Not much further. The performance settings are just adding timing, it may run a little better or a little worse.

 

One of our club members did back-to-back dyno tests on his car using the programmer.

He lost HP and torque when he used the performance tune.

Also, IF you decided you wanted to go back to stock, and it didn't download the program properly you will need to go out and buy a new computer (or find someone to overwrite the flash). It is (or was) somewhere in their documentation.

It is good for what you have used it for...not much else.

 

:yesnod: Don't bother with the tuning.

 

Boy, what raving reviews you guys give it :bs I really like the way the car shifts now and having lower temps dosen't hurt either. :cheers:

 

Dang, I would have sold you mine for much less. I like mine okay for lowering fans-on temps, transmission line pressure increase (firmer shifts), but the "engine power tuning" makes no noticeable difference on my car, if naything maybe slightly weaker in the low end.

I have considered selling the HPP3 in order to buy LT1EDIT software and a cable since I have a new laptop to run it off of. I'd like to play around with some of the settings myself :eek:

 

You asked what we think of the performance side of it. We answered you, you call it BS? I too use it for the same reasons as you, but the performance side of it sux! Plain and simple. I too love how my car shifts, and I also used the fan option, and it was helpful to change my speedo for my new gears, but the rest of it is worthless.

 

I have one and like it just fine.

I also have adjusted my shift points, and compensated for the different tire diamiter of my 18"ers, and adjusted the speedo to compensate for rear gears.

I have the performance program installed and lke it fine!

Only way to know if the performance program works is to take it to the track and run it, the change the program back to stock, and run again.

I think you will like it on a 100% stock motor, but as soon as you mod the motor, your best bet is to custom reprogram the computer

enjoy

 

I'll tell you guys something as a Mustang owner also. For the stangs, you pay like 250 dollars to get a chip burned (mail order, not even custom) if you change your rear gears and want to adjust your shift points, so the corvette programer gives you alot more options even if the performance part of it sucks. Even the stang guys will tell you mail order chips suck and that is mainly what the programer is. I think it's cool that you can adjust your own fan temps, shift points etc. :cheers:

 

Well, we won't hold that against you :D

 

As long as HE likes the programmer
that is all that matters!Even if
it does not do what it should
have for you other guys.

I might could take that HPP off your hand if you're still interested in getting rid of it :D

 

I've heard you can't....at least without going through some major hoops.

Hypertech keys the HPP's to YOUR computer serial #. Once keyed it can't be used on any other car (at least that was the way the HPP 2's were done).

If you buy it, you'll need all kinds of paperwork to send back to them with the programmer so they can erase the memory so you can use it.

It's their way of making you buy one for every car you want to program :mad Sounds like they took an idea from MicroSloth....

 

When programming with the Hypertech it stores your VIN, and can only be used by this VIN. However, if you unprogram the original car, it can be used by another VIN. You can only program one car at a time.

Peice of advice, for what its worth regarding the Hypertech. They are great for tire size/gear changes, and fan control, but not much else.

I had one once upon a time (when I changed my gears), and I went back and forth at the track one day with and without programming, and ALWAYS ran SLOWER with the hypertech performance tuning. Like I said, some of the basic features are useful, but.. read on.

When I started getting more serious with my mods, I sold it on eBay (and actually got about what I paid for it!), and used the money to buy LT-1 Edit.

LT-1 Edit is one of the most versatile programming tools you can buy. You do need a laptop (or, you can use a desktop), but the features are incredible. You won't even beleive the things you can Edit. If the PCM controls it, you can change it.

Check out http://www.carputing.com/ for more detailed info. You can buy the program for $150.00 (half the cost of the hypertech), and you can probably pick up a laptop cheap. I bought a used Dell Pentium for $100.00. So, for the same money, you can get a laptop and an infinately more versatile PCM programming tool.

Sell the Hypertech on eBay (or to someone you don't like), and get LT-1 Edit, you will be very, very happy you did. If you know someone with a registered version of LT-1 Edit, you can get your VIN added to their software for only $50.00 (which is what I did). Like the Hypertech, its VIN dependant. But each program can have up to 10 VIN #'s on it. For the money, there is nothing better. How doe they compare? They DON'T. The difference between the HPP and LT-1 Edit is like trying to compare a CHEvette to a CORvette... And thats no joke.

Best of luck! :chevy

As for selling the HPP, once you REMOVE Hypertech programming from your car, it can be used on another car. So selling it is not a problem. :yesnod:

Nevermind.... :jester

 

In addition to the laptop and LT1EDIT program you must have a custom made interface cable. These cost about $95 each, I think.

 

Thanks for the inputs. I guess it depends how heavy you want to get into the mods (I'm talking about the HPP vs LT1 Edit). If you just want to adjust a few parameters to make the car more enjoyable without alot of hassle the HPP is easy to use, but for heavy modding there is no choice but the LT1. For me, my mustang is what I try and mod since parts are a hell of alot cheaper and it is so much easier to work on (I'm dreading the spark plug wires that I need to replace on the vette). :cheers:
