2.73 to 3.73 tune

[zooguy]

i just bought my 3.73 gears and i am looking to get them installed some time after my next check ... i got a quote from a guy and he said that its going to run me $400 to tune my car after the gear change. now this is also a dyno tune where we will help bring more power out of the mods i have done ... i have a cable and 2 programs ... datamaster and tunepro RT... i dont know squat on how to tune my car but i would like to learn ... i know that the cable works cause i can use a program called Freescan to read off my computer how the car is running. my question is how hard is it to change the factory tune to shift right with the jump from 2.73's to 3.73's?

I use tunercats for this, I could give you the scalar values though to plug into tunerpro. Not too difficult

[zooguy]

is tunercats free?

It will take like 30 secs in tuner cat. Then 4 mins to write the tune lol

what do you mean wright the tune?

[95ImpySS]

Program the PCM. Sending the new tune to the pcm takes about 4 mins. IIRC the tune is only 128kb. Serial is sloooooooooowwww. If you want post your tire size, and Ill get you the conversion info like in that pic I attached.

im about 45 minutes from joplin, mo. my hypertech and tune for 3.73s or at least thats what is says. we could use it if u like

[zooguy]

would you say Tulsa is about half way?

[zooguy]

vinita and claremore look to be close to half way

i know there is a member here that lives in Pryor its just east of Claremore by 10 miles

im not exactly sure. i dont have a car at the moment tho. mine is down for heads and cam

[95ImpySS]

IIRC the hypertech tuners are vin locked. You'd have to revert your car to the stock tune with the hypertech before you could use it on another car.

thats odd lol i have tuned like 4 cars with mine

[95ImpySS]

Hymm. I tried to use one on my 96 9c1 and couldn't get it to tune my car until i went back to the original owner and reset his PCM. Dunno. Glad it works thoe. Hope the OP gets it right.

i have never tuned on that thing for gears. i was guna try it when u got gears but, i blew a head gasket so now im doin cam and everything.

[zooguy]
