Hey guys, just showing off something new that I've been working on.

The Dual Flash PCM is an exciting advance in the Generation III tuning arsenal. 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 preterminated wire that simply plugs into an un-used hole in the PCM's harness. 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.



Outside boxes and 'trickery' for nitrous and boost tuning are a thing of the past. Their reliability pales in comparison to the proven technology of our PCMs, and we have made them better. Some obvious applications include:

Nitrous tuning:
Run a peak N/A tune and then switch over to your nitrous calibration. Run a single stage of nitrous on one calibration and two stages of nitrous with race fuel on the second flash. This is a very useful application because as many of you may already know, to keep cars shifting in the same place with added nitrous often includes lowering commanded shift points. These shift points now work with nitrous, but cause the car to shift too early N/A. There are many more possibilities and combinations.

Boost tuning:
Run a 'street' or pump-gas tune in one calibration, flip your switch and get a more aggessive AFR and spark map for use with race fuel. Turbo cars can use the switch to not only switch tunes, but to also switch MAP sensors. Run a safe 2bar tune with optimal VE resolution on pump gas; flip the switch and change over to a 3bar MAP sensor and tune for higher boost at the track. Again, the track (or "all-out") tune could contain a more aggressive timing and AFR schedule.

Economy tuning:
Use the second flash chip to switch to "economy mode" for fuel savings for trips or for alternate fuels such as E85!

These PCMs will be available with default programming that is found in the 12200411 PCMs. Additional or custom programming is available at extra cost. Please use our contact form (http://www.tunedbyfrost.com/contact.php) for all queries about this product at this time. These PCMs will sell for $475 without core exchange. If sending back a working PCM, a $100 core charge will be refunded. These units are $375 with exchange (or to convert your current PCM). They also include a pre-terminated and soldered Micro Pack 100w terminal that clicks right into your PCM harness with 10' of automotive (TXL) wire to run to your selector switch. If you already have a solid tune, but like the idea, we can move your tune over to both of the boards. You can take your car to your tuner, select the second side, and have him reprogram it. In some cases, the programming changes can be done here on the bench for an additional fee. This is available for [512K and 1M PCMs] 99-02 Fbodies, 99-04 Vettes, 04 GTO, 04-05 CTS V, and most GenIII based trucks.
  ---These rates are board listed rates.  As with everything, nice discounts are available for sticker bearing RPM Members. 

 Sounds pretty sweet!

thats awesome dude. hope to see it do well.

what are you gonna do if everyone buys and you dont get any core returns? do you have a supplier where you can get PCM's for cheap?

 Sure, I can get them even one at a time for less than core. 

 That is pretty neat man!

 This is an update.

 Never mind the pricing, send me an email through my site for the RPM discount.  Those of you with your own tuning software, EFILive or HPTuners or even LS1edit, and have licenses  that are tied to your current PCMs, I can clone the flash chip that I remove from your PCM onto both of the chips on the dual flash board.  That means that each side will work with your current licenses and you don't have to credit it like a second PCM!
