    We are pleased to introduce our new totally unique map switching function. This allows for up to 5 different maps to be selected instantly without the use of any additional hardware.

    The driver turns on the ignition, and presses the pedals in a certain combination, which causes the map to be switched. The current map is then displayed on the rev counter to provide feedback. Press the pedals again, and you switch to the next map set.

    Once the engine is started, the rev counter reverts to normal operation. The last selected map is stored so that it is remembered for the next time the engine is started.

    Examples of maps include valet mode, methanol injection tune, Race fuel tune, high boost drag tune.

    We can map it, but no fancy features I'm afraid.

    Can you do full custom maps??? Its for a PES G2 Supercharger, different injectors, rising rate fuel reg etc. Would like it all done to suit my exact car as PES generic maps are **** aswell as the standard G2 injectors.

    If so, how long, how much and whats involved?

    Unfortunatley that's an older management. We can custom map it, but no launch or flatshift i'm afraid.

    Rising rate fuel reg is very difficult to map for, any reason you are using one? We can msp such a custom setup, but even with a standard fixed differential FPR it is extremely time consuming to get it right due to the time it takes to flash, log tune, flash etc. It would be a minimum of a weeks work and around the £600 mark. We wouldn't let it go until it was right though, providing all the hardware was suitable and working properly.

    Thanks, Rick

    Yep, it will be time consuming and a week is around the timescale i have already spoke off with Regal Autosport.

    Time is no issue with me thou, just want it done right.

    When speaking to Ryan at Regal, he suggested the rising rate reg due to the design of the SC and the fact the car isnt designed to run a SC at the minute, so will help him get better fuel trims etc and more accurate and is peace of mind for me.

    Regal quoted me around £400ish for the map, with new FPR £120 and fit for £70, does your price inc this also or just for the actual map?

    Can you also send me some details of where you are etc, so far only you and Regal seem up to the task, most have refused or simply dont have the knowledge/tools.

    Cheers, Mick.

    Mick,

    our price would be just for the map, and some minor tinkering as required. I actually don't understand the logic of a RR FPR. The whole idea of a vacuum referenced FPR is that you keep the fuel pressure at the injector constant so that you can calibrate only for the injector flow. Rising rates were used in the past for example on speed density cars with no MAF, and MAP sensors which could not detect positive pressure. The rising rate reg would then give the extra fuel.

    As you are using a MAF, this takes care of the extra air for you. You just need to make sure you are using a MAF which isn't going to max out.

    ooo so what about a map with launch and flat shift, then a super UL tune and then a low boost, or is that too much to fit in my 512k ecu,lol

    Can you PM me some company info then and i will give you a shout to discuss what i have in mind and when etc, cheers.

    Mark, I believe that would just be two different maps, as I would have thought Rick could map launch and flat shift into both of the super unleaded and low boost maps.... But why would you want that functionality on a low boost map?

    Rick mapped my car recently and the tune was excellent. Will defo be going back again soon!

    Scott,. it would be one with all the tricks, one with all the boost etc, but no tricks and one basic "valet " mode with none if possible, at least that would be the plan

    Interesting point... If you had a valet mode, would the ECU rememeber which mode it was in for subsequent starts, or would it default to map "0" every time.

    I still dont see if it would remember the previous setting.

    Lets say 0 was "normal high boost", 1 was "low boost" and 2 was "valet"

    I can see that you'd turn the ignition on, and press them in a combination to get it to mode 2.

    But then if you turn the ignition off, hand the keys to the garage, and they jump in, will it still be on mode 2, or will it have reverted back to mode 0?

    Going by how Rick worded it, i think the selected map is stored as the selected type for every ignition on/off etc only until the next time you repeat the pedal press sequence to change to another map, so it will stay in Valet regardless of key removal etc.

    This sounds a pretty great product! I think you will be pretty busy with some of the S4/RS4 boys too if they are compatible. Great work still developing new products for these old cars.
