We are happy to announce the multi flash tune (MFT) functionality using the cruise control paddles is now available via the beta version (1.21). Note this is still a beta and we will be updating and finalising features over the coming weeks. 1.21 has been sent to any workshops customers who have requested early access. The MFT system will only be available to users with the Workshop package.
First we recommend you watch the demonstration of the MFT functionality here if you have not already. This demonstrates how to change the tunes using the cruise control buttons with a brief overview of what the system can be used for.
There are 10 tunes which are switched or interpolated between depending on the setup.
Base Tune (tune 1)
The base tune contains all the major maps that will be toggled when you switch fuel. There is one for E85 and one for 98
Then there is tune 2. When tune 2 is selected the following maps will be switched out of the tune 1 to make a resulting tune that is a combination of tune 1 (base) and tune 2. Tune 3 and tune 4 have identical maps as tune 2. These can be used for multiple boost levels, different cam timing or different fueling.
Then there is the launch tune which is selected by holding the cruise control paddle down. The launch map has the following tables by default. Typically you would run low timing (-15 to -20 degrees), rich fueling of ~0.75 lambda, 30-35 degrees camshaft overlap and a modified duty cycle to ensure no overboosting.
No Flex Fuel
In the example of a vehicle with no flex fuel sensor you will first select the fuel via the kph on the dash when in edit mode (85kph for E85 and 0kph for 98). This selects the base tune. Then you select the minor tune (1,2,3,4) via the RPM, this selects the boost level etc. From this combination you can create E85 valet, E85 low boost , E85 high boost and E85 ghost cam, 98 valet, 98, low boost, 98 high boost, 98 ghost cam.
Finally the launch control tune which could be used for normal launch control or an overboost scramble function.
In the example where you have a flex fuel kit installed the only difference is you cannot select the base tune from the kph edit function. Instead the kph will simply reflect the ethanol % from the sensor. The operating system will then interpolate between E85 base tune and 98 base tune based on the blend curve defined (same as the legacy flex fuel kit).
Instructions for E85 valet, E85 low boost, E85 high boost, E85 ghost cam, 98 valet, 98 low boost, 98 high boost, 98 ghost cam.
Create a stock file.
First you need to create a stock operating system, this includes if the vehicle is already running a custom OS, you must make a fresh stock file. The following standard operating systems are supported. BA, BF, FG Mk2, FGX. If you have an FG Mk1 you will need to convert your operating system to A0TE (HAEE4TY). This is due to memory limitations with the Mk1 which contains the 5R55 5 speed auto code which is PCM controlled. A0TE does not support the 5R55 hence it has plenty of free memory.
To convert to A0TE follow the instructions found here. This will cost 2 extra credits, please contact us and we can refund the upgrade cost (if upgrading to the custom operating system). If you have not already licensed the vehicle you won't need any extra credits. In future versions this upgrade will be automatic.
Create the Custom Operating System
Now to create the custom operating system you will need version 1.21 beta or newer.
Once you have licensed and created your stock file go to "Custom OS Build Options" where you will see the following or similar.
The default options are set to create a cruise control multi tune with 4 tunes, no flex fuel kit and fuel switching via the cruise control buttons.
If you are running a flex fuel kit please change "Multi Tune Type" to "Flex Fuel Sensor". If you are running a single fuel please change it to "Fixed Fuel". Once you have done this select "Custom OS Enable" and enable the custom operating system which will create and save a new file.
The resulting file will open and prompt you to license it, see the pricing section below for details on credit cost.
Once the file is licensed you then need to set up the maps. This assumes you already have a 98 base tune and E85 base tune for the vehicle. First you will need to compare against you known working tune and copy the E85 tune into the E85 base map and the 98 tune into the 98 base tune.
Launch Tune Setup
See the launch tune setup thread here:
Tune 1 Valet
Set the boost duty cycle table to 0 in both 98 and e85 tunes
Modify your spark timing to suit 91 fuel in both tunes.
Tune 2 low boost
Modify your boost duty cycle to suit low boost in both tunes
Tune 3 high boost
Modify your boost duty cycle to suit high boost in both tunes.
Tune 4 ghost cam
Modify the VCT enable/disable scalars to -1000 (see the ghost cam thread for details)
Modify the VCT overlap and VCT max overlap tables to command 25-30 degrees overlap
Guide and explanation coming soon.
The total cost for the multi tune system is 10 credits ($500 ex). If you have previously licensed the file you will be only charged the difference.
The preliminary pricing of the various custom operating systems is as follows:
Standard Custom Operating System or Legacy Flex Fuel OS: 5 credits ($250)
Boost by gear/speed.
TMAP switch over logic (to allow for a 4-5 bar boost sensor and a standard TMAP sensor).
Speed density map vs rpm (for vehicles with a locked camshaft to create a traditional VE style tuning map).
Flat shifting TPS enable setpoint (allows manual flat shifting with injector cut out)
IMRC output runner control (for nitrous or staged fuel pumps which will turn on at a specific rpm and load.
Flex Fuel OS or dual maps via external input: 7 Credits ($350)
Includes all features above.
Dual maps (base e85 and base 98) which are interpolated via a flex sensor or switched by an external voltage input.
Multi Flash Tune via the Cruise Control Buttons (MFT)
Includes all features above.
Launch tune via cruise control paddle
4 selectable tunes via the cruise control buttons
As part of the MFT system the vehicle performs a dash sweep when the ignition is turned on. The RPM and KPH sweep causes the BCM (body control module) to believe the car is moving, this then activates the low oil pressure alarm and the seatbelt chime. We are working on masking the low oil pressure and charge fault alarms. The seatbelt warning chime can be disabled via Ford IDS, we are investigating to see if we can disable this via the editor, otherwise anyone with Ford IDS can do it for you. These alarms will only occur if you turn the ignition on and do not start the car.
This is a BETA version of the MFT. It has been tested on several BA, BF, FG Mk1, FG Mk2 vehicles however you must be aware that it is a beta and we will be making regular changes, this may mean you are required to recreate a custom OS over the coming weeks. You must perform all testing on an engine dyno and ensure fuel trims, AFR, commanded timing matches your previous tune before the vehicle goes out to a customer. Ensure you warn the customer of the risks of selecting the wrong fuel, if you think this is likely we highly recommend installing the flex fuel version of the MFT software. Ensure your customer has been informed that this is a new system and there may be tweaks and changes required over the coming weeks.
Currently only the Flex Fuel and Multi Fuel setups with 4 tunes have been tested. Single fuel has not been tested, nor has the 2 tune version of the setup. We will be testing those setups this week (24/6/19).
We have a new UI Wizard that is in the final stages of being tested. This wizard will allow you to pick and choose exactly which tables go into the launch tune and tune 2-4, this means you can make all sorts of different combinations depending on the application and no longer have to ask us to add in different tables for you. This wizard is also far more intuitive than the current drop down menus. This will make it much faster and easier to setup a custom operating system. This should be available in the next few weeks.
