Into passenger footwell. And no, you don't have to route your intake or IC piping there... =)

Yes, there's a 3l version.

You are correct. The V-FLEX software will be provided with the new kits. You just purchase the Vitesse MAP sensor. The MAP sensor is unique and the one we sell must be used, as we programmed the DME for it.
The Vitesse PiggyBack will be used to set the Overboost and the Rev Limit. Actually there are other things that can be done, more on this later
The tuning based on endine size does not change. I still need to know the displacement, CR,... this is basic tuning and does not change. However, we add the new features.

okay, so just so I'm clear...
You buy one of the kits, injectors, bosst controller, and ad the MAPsensor and harness, for 125.00, is that right?
The piggy back is the tool used to set the overbosst protection and the rev limit, which can be set lower, but not higher than the max for which you have programmed the software. Is that also correct?
If the above are correct, does that also mean that mild displacement increases will require little modification to stock chip programming? example ST III for a 2.5 run on a 2.7?

Thank you Olli. Taking the stock system to the next level is always a good thing.

You can install the MAP sensor anywhere in the car, as long as you get a vaccum/pressure line to it. More than likely it'll live by the DME and you tap into the KLR vacuum line. The MAP sensors feeds directly into the DME. We use a "unused/vacant" input line on the DME.

You got it. I will figure out a procedure to handle upgrades, I will detail the procedure shortly. At the moment, I'm trying to get existing orders out. I would like to wait a couple of weeks before starting the upgrades. The MAP sensors are unique and I can get them from one source, so I have to stock up as well.
For those interested inthe upgrades, please drop me a email so I add you to the list.

Very cool, the timing issue is the main reason I want a standalone.
The MAP sensor is limited to 30 psi, what happens if I run 35psi or even 40psi(yes I do plan to)? Are there any plans to up it to 4 or 5 Bar sensor?
I am curious why not switch to the MAP for fuel also and eliminate the MAF entirely?

Some 951 owners may not want to add a PiggyBack, then the V-FLEX software will disable the features that depend on the PiggyBack.

If you run 40psi I would not want to be around
. Once you cross a certain boost level (x-psi), you use the max programmed ignition retard. I strongly doubt many people will be running higher than 30psi. However if you do decide to run higher than 30psi, we have a different way to handle it and to give you additional control.
At this time we do not see the need to support more than 30psi MAP sensor. If there is a need, it can be done.
Using a MAP sensor to control fuel has many disadvantages. This has been discussed plenty when comparing a MAF system to a MAP system. One of the advantages of using a MAF based system for fuel is that you will always know how much air is going into the engine. With a MAP based fuel system, you only know boost/pressure. A k26 running at 1bar boost will generate X amount of air. A Stage 3 turbo at 1 bar boost will generate Y amount of air. "Y" is greater than "X" yet boost is the same 1bar. Also with a true Air Mass system (MAF) various conditions are captured by default (temp changes,..). This is a single advantage for the MAF (or disadvantage of a MAP based fuel system).
