I recently installed 3.42's and I wanted to know my options on recalibrated the speedometer. My local dealer wants over 60 dollars just to program it, which is crazy. Where all can I get it done, or with what equip do I need to do if myself?

 

I have yet to do this so im no expert... but I know you can do it yourself with: A Computer, a special link cable (going from the comp to the OBDII connector under the dash), and some pcm programming software for the computer.

 

....maybe I shouldve mentioned: that cable you need is almost as much money as having the dealer do it

 

that sux.....can anyone give me some more info? Is it just the cable that you have to buy? Is the software free? Where can I buy this stuff at? TTT please

 

your best options are to either
1. find a used hypertech power programmer for ~150
2. let the dealer do it
3. take advantage of the situation and get a custom tune from www.madz28.com or www.pcmforless.com



LT1 edit is $550.....but it comes with the cable which is $100

 

I've talked to my local dealer, and they want almost 70 dollars just to recalibrate it, I know this is BS as it only takes about 15 seconds and requires no physical labor what so ever.

I would'nt mind even paying 100 or 125 if it was for a program like lt1 edit or something where I could hook my laptop up to my car and change settinging and I could get a way to read engine codes as well.

Does anyone know of any do-it-yourself programs that will let my check codes and change engine settings as well as recalibrate my speedometer for under or around 120 dollars?
