So guys after a long distraught decision wether to get hp tuners or have someone tune me here locally ive finally made my decision to go with the vector motorsports tune for reliability and practicality reasons .....

however i have some questions first off
- Is the Tcm seperate from the ecu or are the ecu and tcm one big module??
-I want only to get the ecu tune i have NO interest in having my tcm tuned being as i have an auto tranny is this possible or with the tcm have to be modified ???


just incase ur wondering why i dotn want it tuned is because i have the autotransinterceptor and i like the freedom that i can go back to the stock smooth shifts at any time ..............

TCM is seperate from the VCM, you can only retune the tranny in person. You will be fine. Though, you will have a locked VCM from Vector :-) enjoy.

Cloudio

Thank you Psykostevo
Much Appreciated

ECM in this case, not VCM or ECU. They are separate modules, tuned independantly.

Cloudio

ok great thanx

let me know how that works out. Im just about ready to give up on HP Tuners...........

I might just get the 'balt dyno tuned for a baseline, get rental car, as my Cobalt is my only means of transportation, and send Vector my ECM to get tuned, re-install it and enjoy it.

hUh and have 3days of no car and waste $500 on a rental car bro .....just do what iam doing buy the performance ecu outright for only $200 more which makes a total of $550 with no down time and when it arrives just plug and play +++++if anything ever goes to **** you got the stock tune/ecu sitting nicely in storage
for me this plan is practical and more then bulletproof


Cheers

yeah, but like Brandon97Z told me (he has the Vector tune I believe), when you buy the new ECU outright you gotta take it to the dealership and have the crank re-learned, which sounds like a pain. I'd rather just save $200 and pay the $17 a day from Enterprise for a shitty little Kia Rio or something. Even after a rental car, its still like $150 cheaper just to keep your ECU.

I'm going to get my car dyno'd next week at Pro Motion Tuning to get a nice baseline. Then im gonna order the Vector tune and send off my ECM + get a rental car the following week, and then have it dyoned again when the ECM is back and re-installed. Then maybe we can share some results! Good luck and hopefully all goes well for us.

Psykostevo

Be sure and let us know how that turns out!

WhiteSSBalt

lol, in this thread you want to know how everything goes.......

but in the other thread containing Vector information you down it........

strange.....maybe in this thread your just being sarchastic.

who knows.

Cloudio

its no hassle at all Case Relearn takes 30 bux and 5 minutes at your dealer ...they wont ask questions and if they do ...u simply say you bought a back up ecu just incase. anyway no biggie just wanted to let you know its not a hassle at all infact its rather common especially among newer cars.

WhiteSSBalt

what is a care relearn exactly? Will I even be able to drive the car to the dealership to get this procedure done? I still think getting a rental is cheaper than paying the extra $200, lol. Plus, I might get something badass like a beige Kia Rio! Ooooohhh yeaaaahh!

DarkSergeant

I'm pretty sure that $200 is a core charge and is refundable, unlike the $150 for a rental..

Cloudio

a case relearn - allows your ecu to get insink with the rotation of the crankshaft via the crankshaft positioning sensor ......thats what the relearn is for and YES you can drive to the the dealership you will just have a horrible idle and DO NOT GO WOT because if you did the engine would potentially rev itself to death .....with out the relearn the ecu really has no idea how fast the crank is moving ...........however if you just abide the law and drive normally there get the relearn done everything is FINE and YOU save your safe the embarrassment OF in driving a shitty rental
