hey does anyone know if you can change anything with HP Tuners on our car? My buddy owns a shop that currently tunes all ss/sc and well not ss yet cuz its not to popular around here..but they are hiding. can we change anything guys? let me know

 

No 2.2 Support yet

 

from wut i understand u can change HP Tuners can modify the transmission. The 4T45E is quite an old tranny in fact. The TCM is a seperate computer from the ECM in my car. I just wanted to screw around with a couple things, like line pressure, shift points, etc...so i think u can..im just not 100% sure. any ideas?

 

I won't advise until it's "fully" supported

 

yeah we are unsure about it....so i think im gonna call HPTuners and find out myself, just to change up some stuff.

 

someone said they had the stuff ready to do a 2.2 they were just waiting till there was an outcry for it. but i believe that person in particular was FOS

 

i remeber some 0ne saying it did support the tranny but not the engine it cant hurt to try if it cant read it it cant f it up

 

oh it can hurt to try lol

 

are they still a supporting vendor? why not just ask them? clearly there are some of us waiting and hoping

 

HPT does in fact support our TCM's, but not the ECM. You should be able to modify the items you discussed. However, HPT software operates using a credit based VIN indentification system. If you use it now, you might have to pay for it again when the ECM support becomes available.

 

so then they do have something in the works still for the 2.2, cause i heard they dropped it

 

Halfcent...me and hack are going to be doing this at my friends shop Cobalt-Addiction probably on friday..will this work and be worth it?

 

I don't know, I haven't tried the software yet myself. I'm not going to bother until I can get the entire package. You should only be able to tune the trans for right now. What do you want to change? With my built trans, I'll be looking to change the torque limit tables, shift speeds and pressures. I'm told HPT gives you dynamic control as well, meaning you can lock the trans and converter in a specific gear for acurate dyno tuning.

 

to the u the truth i dont know much about HP Tuners..so im not sure wut i can do with the tune

 

I want to up my line pressure's in both "2" and "L", change the shift points in "2" and extend the "L" gear to 3rd and 4th gear

For "2" I want to up the line pressure to high and for "L" I want to make it almost extreme, I'm going to do some testing first though, I want "L" to be my new drag racing gear, but i need to extend the limit past 2nd gear so I can go beyond 80. And I want to have "2" as an aggressive gear.

 

i see....and u can do this with HP tuners...im gonna get in touch with kenny from Cobalt Addiction or Donna...im out..ill get at u hack 2morrow

 

Looking forward to having a sick upgraded tranny
And an awesome night out in LI :
