Chips for my 99 Vette

[Keithdrummond]

Hi Folks
I am a newly joined member, living in Ontario Canada. Sadly, we store or cars from November to April.
I am interested in installing a chip into my 5.7 litre, otherwise unaltered. I've run into several that, upon researching, are nthing more than a resistor. Can anyone pass on a proven supplier as I have only Canukian sources who reall don't get too involved. Thanks in advance

99's don't use chips
you re-program the computer

Re-programing a 1999

Your 99 corvette needs a special control panel device that allows you to change many of the factory set parameters and while I have no doubt you could afford it, This is a task MUCH BETTER left to a professional shop with a dynometer and a very experienced "Tuner". The technician can, once the car is latched down on the dyometer and running in gear can reproduce the exact reading that your car has programed into it when they were built. An experienced technician/Tuner car "Enhance" many of these parameters, but it really a job for someone who's done fifty or a hundred Power-train control Modules. Once done, the can will rely on those settings and those only. So you really need someone who know both your LS1 engine and the operating environment so that you get just what you wanted in performance and no ill-effects from the re-programing. This can only be done while the car is running on a dynometer with the engine both cold and hot and how it performs while in operating motion. Good luck !

Re Chips

Many thanks for the input. I will try to locate someone competant, as you suggest. As a new Vette owner, it's great to have this forum to ask questions. Only 5 more months till out of storage time

I agree with the above
but there some mail-order tunes that may fit your needs
East Coast Supercharging does good ones from what I hear

The factory did not leave too much horsepower on the table. Depending on what you have manual / A4, you can improve drivibility, but without any new equipment, the "tune" may not be worth it.

For the price of the tune, you can purchase the hardware "for a few dollars more" (great western too) and use an older laptop and tune it yourself.

Absolutly, No programing can replace how much extra air you can get into and out of the engine. I left my PCM along, but I installed a Corsa 'Pace Car' exhaust system, and a modified air cleaner/intake system. A engine is really just a air pump, The more air in, the more out. And an increase horsepower as a welcome bi-product.

I think we can all agree an internal combustion engine is an air pump, but you cannot maximize hardware changes without retuning the computer tables. Key word is "maximize".

I'd say ya oughta do BOTH :L
