re-adjust the speedometer for lower gears????

[94CamaroZ28]

is the only way to re-adjust my speedometer (because of 3.73 gears) with a power programer?

[Chevyracincamaro]

im pretty sure that the power programmer does that. 94 and up the speedoes were comp controlled so if that doesnt do it, the dealership should be able to. but im 99.9% sure that the commercials for the programmer said theycan do it...

The other way would be the SLP speedometer calibrator. SLP no longer sells these, however they are sometimes on ebay.

Look in a Jegs magazine... They have a couple of speedo re-calibrators.

Here check this out....

140's a little steep for a speedo correction...

It's 349 for a hypertech programmer. So if all you wnated to do is do a gear change it's cheaper.

[Chevyracincamaro]

this is true, but i wonder if it would be cheaper to just let the dealership calibrate the speedo...

go here and get the 30 day free trail program...

you need to get the file for you car, its like $20 bucks

you will be allowed to go into you ecm and change the tire size, gear size, and any else you want...
you will also need the cable

make sure you get the good cable because you do not want to fry the ecm, also as long as you have this cable you can scan your car for any codes you need to... so it pays for its self very quickly

The dealership will do nothing more than flash the stock programming in per your VIN number.

Anything other than the stock gearing and you are out of luck.

good to know...

has anyone here purchased a power programer?... do you think it is worth the money? did you have any problems with it?

[96CamaroSS]

I bought one for my 96 SS mainly when I changed the gears.
I think they are worth the money. You can change gear ratios, change shift points (auto only), raise or lower you top speed limiter, change what temp your fans come on, change your rev limiter... But remember if you program your car with the programmer keep it and don't sell it. All your stock data from your computer is saved in the programmer along with your cars vin number. So if you go to sell your car or take it in for repairs return it to stock.

They are so simply to use even a monkey could use it.

96CamaroSS...it's $350 for the hypertech programmer which does all those things you listed in the above post? Interesting. What all do you need to have to use this? Do you need a laptop computer? or what?

i plan on switching to 3.73's in my 91 how do I re-calibrate the speedo then?

You don't need anythign, just the programmer. Sucks for me how they only make one for v6';s for 00-02
