I have a ProCharged 416 that I would like to be able to swap from a 3.85 pulley to a 4.25 pulley and back and fourth depending on what I'm doing with the car. Is there a device that I can hook to the 2002 camaro computer that will enable me to swap the tune back depending on what pulley I am running?
It is a speed density tune.

I'm curious of this also! It would be great for me to be able to switch back and forth between a e85 tune and a 91 octane tune! I'm thinking that we would possibly be able to do it with the hptuners hand held tuner once it's done by laptop by a professional tuner?

if its tuned right, you wont need two tunes.. the ve table can account for a ton of different boost levels

Thread was back in '09, did these things take off. It wouldn't seem that way since I have never heard of it or seen a new article. Sounds like a really cool product though.

Or when you go to swap pullies you simply load your other tune from EFI Live/HP Tuners and call it a day. No special HW required.

except HP Tuners or EFI live...

What does this mean.

It was a poor attempt at sarcasm.

Anyways, for a boosted/built setup like yours, having the proper tuning software in your hands is worth its weight in gold and practically considered standard equipment. And compared to a dual PROM PCM, EFI Live or HP Tuners is hardly considered special equipment.

Just pointing out its not as easy to flip a switch. I have HP Tuners and have about 2800 wrapped up in it. I do agree that having it is the best tool that I have bought. Once you buy it then you have to learn how to use it too.

You guys have me a little lost with the sharp wits and clever back and forth banter but here is my question.
Would it be beneficial to have the twin chips and switch, have a normal tune, then say flip a switch to have your nitrous tune come on?

Or...

Someone else is saying carry your laptop with you, with various saved tunes (HP or EFI) and load them as necessary so you don't need a switch?

Thats what I am afraid of by going this route $$$ then learning how to use it effectively. I do not have allot of desire to be a tuning guru. Once it's set I want to leave it alone.
The dual chip sounds good, I need to talk to my tuner and see what he thinks about it.

I find it kind of odd coming from other platforms that the hand held devics such as hptuners and efi live are not able to hold and flash tunes. Seems they need to catch up to other in the industry on this aspect.

Its not to hard to carry a laptop with you in your car. Just load a different tune.

As far as I knew, you dont NEED the laptop to flash a tune. I always keep my laptop with me so it hasn't occurred to me to try and flash it without it.

You also dont NEED the laptop to datalog a run, I have done that with only EFI Live. I also have less than $1000 into my EFI Live and still have credits left, meaning I could do a tune for someone else and recoop money. You only need a wideband with an analog output and the tuning software.

I just see the dual PROM thing being a PITA without actually owning the software to modify the tunes, but to each his own.

No, but for people who don't do their own tuning it would be nice if they came out with a handheld flash device to be able to have multiple tunes. When I tuned subarus I could tune a guys car and have up to 50 tunes loaded on their hand held flash device that they could change on their own without a laptop (some tunes on the fly) which came in handy for e85 tunes, race gas, economy, ect.

Omnituner is the company that frost gets all that stuff for the dual chips from...if a person has soldering equipment and knowledge on how to they could modify their current pcm for much cheaper!

You can log without a laptop but I don't think you can load a tune. Although I've never had a reason to try it or look into it with HP Tuners.
