hey after reading stickies, ive found the hypertech tuner, i have a 94 formula with a A4, ive read some bad things about the tuner but from a stand point of correcting the speedo after gear and tire change, and adjusting fan speeds/shifting points and removing the top speed limiter (although ill probaly never need it) is there anything bad about it from those stand points?

also the one ive found PN 345752 says 95 camaro, 94-95 corvette, 95 firebird
would this one still work for mine although it says 95? to my knowledge (which isn't very vast on the fbody cars yet) i don't know of a difference in the 2 years

In my experience.....the only thing worthwhile (and barely, at that) about the hypertech is it's ability to change the settings for tire diameter and gear ratios.

From a performance standpoint......pass on it and get a real tune from someone who knows what he/she is doing.

kk but how does that work with the sending in your computer tunes? i plan on doing gears, tires (not sure if ill go taller but maybe), and cam but at different times, so do i order a tune for the gears, then for the tires, and then for when i do the cam? the last time i did a build it was with my buddy which is out of the marine corp and moved back home, and we switched it over to carb'd and while he was finishing with tuning it i was nodding off in a folding chair lol

Ok .. so kw is completely correct. And yes a tune will be able to change your ratios so speedily is correct.. if you want tye ability to do both , which is what im doing because I already have a hypertech. Have the tuner flash your ecu to handle any mods you want , spark curve etc... But have them leave the hypertech stuff alone.. then you can install the hypertech and change those settings at will... But IDE fully agree w kw that aside from speedily and shift firmness they are fairly useless. And any tuned will be able to do the smae and more

dont waste your money on the hypertech, why are you afraid of your laptop?

1. buy the cable ($75). buy the definition file for tunercat ($30). this is WAY cheaper than a hypertech tuner.

2. plug cable into your laptop. plug cable into your car. turn on the key

3. tools menu. read pcm. then speed calibration. then write pcm

there you go, tires and gears are tuned.

when you finally get a cam, since you aren't an experienced tuner, you can send your 'bin' to the tuner, he can set it up for the cam, and you can write it yourself, with the cable. that way the ecm never has to leave the car, and you'll save on shipping.

94-95 are the same (OBD1). 96 is OBD2

for the basic adjustments the OP asks the hypercrap will "work". anything about "performance" tune features of the hypercrap are worthless.

tire size, gears, cam, injectors, heads, throttle body...all require PCM adjustments. if not doing "motor" work for some time a used hypercrap would suffice for the tire/gear swap. Then after motor mods get a real tune which can also address any gear or tire change at no extra cost

Why spend $350 for a new one or $200-250 for a used one, when tunercat will do it all for much less. You can get the deluxe tuning pacage that includes; cable, tunercat obd1 tuner, $EE definition file, and the scan program DataMaster. All for the same price as a used Hypertech, about $250.

well, i didn't say im afraid to use a laptop, but thats great for $105 i can get a cable and a file....... i have a desk top.... lol might look abit silly riding around in my car

ill shop around for a cheap laptop too bad they don't make this kinda tuner for a smartphone :) although if they did noone would make a cable for a phone to a obd1

i guess as long as i can find a laptop for under $200 ish ill still save money
craigslist here i come

EDIT:
winning just found one for $75

An old pentium 2 laptop running windows 98, or anything in the pent 3 or 4 class running windows xp, will run tunercat & DataMaster just fine.

I see those older laptops on craigslist, all the time for real cheap. You might even know someone with one that will give it to you.

Hey guys,
Just to add on here, I also had questions regarding tuning. I have a obd1 cable and a laptop. My '95 runs very rich. The owner before me had a supercharger on the car and who knows what else. And I'm not sure it ever got tuned back when the supercharger got removed. Being that I don't know all the mods on the car. How do I go about knowing what to change in the computer? is there any learning material that you know of?

Thanks! I don't mean to jack the thread, any help is appreciated.

Yes, tuning is something that you need knowledge to do correctly. In the pcm section, in the sticky threads there is tuning info. Also at LT1 PCM Tuning - Welcome! there is good info. Lastly, do a google search and see what you can find on obd1 pcm tuning.

If your car is back to stock, then the stock bin file can be uploaded to your 95 with tunercat obd1 tuner. Ask in the pcm section and I'm sure a member will have the stock bin file you need. That way, for now, you can simply upload the stock tune, then start learning about the changes needed when you mod the car.

it would be a good idea to do a datalogging run first too, that way you can get a rough idea whether it's the tune, or if something else is going on!

but yeah i'd flash a stock bin back on there pretty quick, and work from there
