How do I ask for a gear change at a GM dealer
Hi
Re 98 Camaro
I want to change from the 273 to a 342.
I have asked 4 different GM service depts in my area about reprogramming my PCM and non of them know what I was asking. They all when to their computer and then told me there was nothing showing.
Can anyone help me out? Is there a part number I need, or do they need some type of equipment? What should I be asking for?
Thanks JA

Yeah, that computer tells everyone at a GM dealer everything they need to do for the day... when to eat, how fast to breathe, when to take a p!$$, you get the picture?
Heaven forbid somebody tries to THINK while they're at work.

Hi
Thanks for the info. There are 2 dyno shops in my area but neither of them have edit software. Actually I do not think there are any shops in Western Canada that know how to.
I purchased a Vinci programmer for 98, but I had to send it back for a refund. Unfortunately, it does not work with the Canadian PCM operating system. Atleast that is what Vinci told me.
I don't want to spend $500 on a Hypertech. Edit software like HP Tuners is close to $1000 when imported into Canada, I don't know how to use it anyway.
Pulling out the PCM and sending it to someone might be my only option. It also gets expensive with shipping, exchange, brokerage fees, etc.
I will try Madz28
Thanks

tuner pro, which is free, can be used to change the speedo. You'll still have to get Winflash for $20, this is assuming you have a cable.
for 3.42s you want to use these numbers.
Speedometer scaler ---------------------------12
Speedometer scaler,fraction--------------------1.018
Time between pulses for stop-------------------76.35
Pulses per driveshaft revolution-----------------17
Scaler scantool--------------------------------46.227

Ya I got the feeling that because my car is a 98 it was more difficult. I think it is easier for them on a newer car. That is good news. I will keep trying. There are many other GM dealers around here.

ITS HUGE... BTW..THE COMPUTERS ARE THE SAME,EXCEPT the calibration from miles to kilometers. you say 2 dyno shops do not know what to do??? I sure don't know which ones you are referring to.
I use Mopac alot. They give me great prices and service. They installed most of my suspension mods. They have Mustang dyno and advertise dyno session for $75.00 and a dyno tune for $150.
However, they have absolutely no tuning software for any make or model. I had my car on their dyno and they charged me $175 for a dyno graph. There was some extra time as my car experienced an engine code while on the dyno. I think I had bad fuel at the time. I feel $175 for a dyno graph is quite over priced.
I asked what the difference was between a dyno session and a dyno tune and they could not give me a real answer. Unfortunatley they do not go into the PCM to do any tuning. I believe they send PCMs out to an American source for a mail order tune.
Don't get me wrong, I am not trashing Mopac. I will return to them for future work. There is just not enough of a local market for them to make it worth while to buy a tuning suite.
I was refuring to Mopac and Haney Hi-Performance. Haney can tune, but also do not have software.
How do you like your True Trac? IWE wants to install an Eaton and claims it is more reliable. I have heard the True Trac is realy nice. Just woundering the best way to go, once I figure out how to do my PCM.
Thanks JA
