Dual PCM programs
For 2012 the mustang boss 302 will have dual PCM programs. Each one will be activated by a different key. One is for street driving and the other changes many parameters and is designed for the track.
Ford says some of the track parameters would not be good on the street like deceleration and throttle response.
So do you think the vette could benefit from dual pcm programs? If GM went this route I would guess many vendors who make a living off tuning will be looking for new business but the general public would probably love to have another tune which comes straight from the factory.

My '03 SRT4 had a Dodge Factory package that did the same thing (Stage 2 w/toys). Purchased through the Dealer, could be installed by the Dealer or DIY BUT VOIDED the Powertrain Warranty.

But I think the tuners might have MORE business tweaking the "track" tune, as more people would be convinced of what we all know - that there is add'l power available in the tune.
I run multiple tunes based on weather and whether I run some race fuel or not...being able to turn a key to access the track tune would be very handy.

I want to do something similar. Keep my current tune for the street and another real aggressive tune for the track that requires race fuel. All I would have to do is load the new tune when I get to the track. But doing this with the turn of a key would be cool. No need to upload new tune, etc.

For the folks who have no interest in learning the software, it is a great choice.

Well, here's a problem...once you start scanning and tuning, you want to scan each run to see how the car (and your driving) are doing. Which means you will carry the computer anyway, and since a tune takes all of 16 seconds....it's kind of a moot point for guys like us tinkerers who like to scan and tune.

My thought, as you stated, this is for the person who wants to do both but has no interest or ability to tune.

I think for FI this would be popular. Have a normal NA tune and be able to switch to a nitrous tune w/o uploading a new program would be nice.
There may be times when the laptop is not in the car when it might be nice not to switch.

I think it could be a good thing for everyone, vehicle owners and tuners as well.

What ever Ford offers in the Mustang or GM offers in future Vettes they will each have to meet emissions regulations even if intended for the track. Since it will be possible to switch between the two there is no way the government wouldn't insist on both tunes meeting government regulations.

I like the idea of two tunes. But, using a key to switch blows in my opinion. I want to be able to use full power at any time. Do you really want to pull over and stop then switch keys everytime another sports car pulls up next to you? I suppose you could drive with the performance key all the time but that would defeat the purpose of two keys wouldnt it.

The Dual Flash PCM is an exciting advance in the Generation III tuning arsenal based on the Dual Flash boards from OmniTuner. We all know how incredibly capable these factory PCMs are at controlling all types of setups (with custom MAF, 1, 2, and 3 bar operating systems) and now with the ability to store and use TWO COMPELTELY separate calibration files that are chosen at the flip of a switch by the driver, they are stepping into territory that even standalone controllers do not tread through.
We open up good, tested, core PCMs and remove the surface-mount flash memory chip. It is replaced by a board header and a custom board (made by Digital Inflection Corporation) that has TWO flash chips already installed. The switching (or tune selection) is accomplished very easily. We assign an unused PCM pin to carry the switch circuit to the board. Included with the PCM is either a harness terminal or a pre-terminated wire that simply plugs into an un-used hole in the PCM's harness. With the car off, if this wire is grounded, one calibration is selected. If the ground is opened up (floating), the PCM will boot with the second calibration loaded. The finished PCMs are thoroughly tested.

This may be a problem in stage two and stage three regulated air emissions states, but may be acceptable in others.

so if your car breaks down you have to run home and quickly change the ECU before it goes to the dealer or do you carry the 2nd ECU with you all the time so if you break down a long way from home you just change it on the side of the road?
