Re: Hypertech Programmer (TxAgNavyVette96)
You'll find alot of Hypertech bashers here. With good reason. The "performance" end of it is worthless. However, there are some benefits. For me, I used it to up the rev limiter, adjust for my speedo with gear change, adjust my fan temps on/off with my 160 degree stat, adjust my shift firmness, and adjust my shift points.

I think it is worth having for the cooling fans and gear settings, ect. I'm fixing to buy one myself just for that. I'm right there with you on the Performance end of it... Your not going to get much of anything. I think I read some where the LT-1 picked up about 10HP. Which it should pick up some at the track with the Hypertech just running cooler. Cool Temps = faster 1/4 mile but again I think your not going to see much.

pcmforless.com will do the same thing if not more for what turns out to be quite a bit less than the cost of a new Hypertech. You should check them out. There are also a number of guys one the forum (no experience with them, just read about them) that do PCMs.
While you are doing the fans, I think they can disable CAGS, VATS, and give a little more HP.

Re: Hypertech Programmer (LT-4 CE)
Maybe so but sho would want to risk pulling and sending their ECM unit off to wherever to get flashed and sent back. :crazy: Hypertech = less risky IMHO

Re: Hypertech Programmer (TxAgNavyVette96)
I agree with most of the above... I'd only use it for the fan temp switch. You could sell it on ebay and use the $ for other mods. For the $350 it costs new, i'd get a camber brace and a k&n with open lid and pocket the change... Il'l likley go with pcms for less when I eventually get programming...

Re: Hypertech Programmer (TxAgNavyVette96)
i think that the hyper tech works better than waht most people give it credit for. the last time that i went to the track i took off the hypertech for the first run. and put it back on for the second run. i did notice a gain in both trapp speed and quarter mile time. where the run with the hypertech was actually better.

Re: Hypertech Programmer (comp94)
I agree with above. Used is the ONLY way to go. I got mine for $150 on the forum. PCMforless.com wanted $80-$100 not including the shipping of my PCM. At least I can sell the HPP later, and recover some of the expense.

Re: Hypertech Programmer (birdsvette)
I have a maybe stupid question, Do you have to put in a 160 degree stat to lower the fan temps to go on. Thanks Brian

Re: Hypertech Programmer (Corvette1996LT1)
I quess I am missing something with my Hypertech. Lets see, I install a 160 Hypertech stat and use the programmer to turn the fans on early, which means 192 with the Hypertech.
So we install a 160 stat and then let the motor get to 192 before we turn the fans on!!!
Can anyone explain to me the logic of this????

There are two settings, one for if you are running the stock stat (192) and one for if you run a 160 degree stat (something around 160ish, don't remember off the top of my head)

On my '95 the 160 setting in the hypertech turns fans on in low rpm mode @ 185 coolant temp. If the car continues to get hotter it will next switch them to high rpm fan speed @ 192/193 ( seem to remember it being 193...). The hypertech's 180 stat settings turn the fans on in low rpm mode (in my car) @ 212. Not sure what coolant temp trigger it waits for to kick them to high rpm mode, though. The stock GM programming kicks the fans on in low rpm mode @220, and high rpm mode at 230 or 235...can't remember which.

Re: Hypertech Programmer (no_radio)
You are not correct, the fans come on at 192 for the 160 stat.
I have talked to Hypertech & they could not tell me any details regarding high or low speed settings. They would just say fans on at 192 & off at 185 just like the book says.
I used to have a very early LT4 vintage programmer & the fans came on very early & the car never went above about 174 under any condition. When they replaced the programmer because it would not correct for 4.10 gears, the new programmer now allows the car to run up to 192 under hot air conditions.

Re: Hypertech Programmer (LT4BUD)
For my car, yes I am correct :D
I made those observations by programming my car and then letting it sit and idle a few minutes in the summer heat. I noted the coolant temp readout on the digital speedometer gauges display when the fans kicked on. I also noted when they kicked off. I did this for both Hypertech settings: 160 and 180.
Seeing is believing. Try it you'll like it :)

Re: Hypertech Programmer (Lone Ranger)
Hypertech changed their programming from the my early model til my most recent model regarding fan turn on programming, so obviously what you observed on your car is correct for your car.
But the instruction book clearly stats 192 for the 160 setting & when I talked to them they restated this to be true for my vintage.
What complicants it even more is how the A/C effects the turnon temps, it appears to me the fan comes on low speed any time the A/C compressor is on.
I do know that my car now gets to 192 with a 160 stat and with the old it never went over 174.
Is it possible my programmer is screwed up???

Re: Hypertech Programmer (TxAgNavyVette96)
I recently installed the Hypertech program and am very satisfied with it. I went wtih the power program,shift firmness and 195-185 fan setting with the 160 thermostat. I don't know if the car is faster since I don't race it but it absolutely feels faster and I love the firmer shift points. I am very satisfied.
