Description
Software development for tuning of 6 cylinder motors is currently on going. We are currently working with multiple customers on porting the full suite of custom software options available for the 5 cylinder motors to 6 cylinder cars. Please be aware that during the development process all code modules may not yet be fully functional and you may be asked to flash software which is currently in development.
With the purchase of this product, you will receive a 960 M4.4 ECU modified with a bootloader switch for flashing new tunes and a MAP (boost pressure) sensor for datalogging boost values. This is a full tune, calibrated to your exact setup, which comes with all the support necessary (logging and reflashes) to maximize the amount of power your setup can safely produce.
For a basic primer on how iterative tuning works, please see the how it works section of the website.
Options Explained
Core Provided: If you prefer not to send in an ECU for modification, leave this option as is. We don’t need an ECU from you, but since we do have only a limited amount of 960 ECUs on hand, we prefer it if you can send in a core ECU. If you’d prefer not to pay the $75 core fee, you can send us a M4.4 ECU from a 960, S90 or V90. If you’d prefer to send the core ECU in after a tune purchase, the $75 core fee will be returned to you after we receive the ECU. If you are unsure if your ECU is a suitable core, please email us a picture of the label.
VAG-COM Cable: This is required for logging and flashing new tunes. If you do not already have a VAG-COM cable you will need to purchase one.
Ignition Coil Type: The factory coils utilize an external ignitor. For a stronger spark, ignition coils from the later model ME7 cars (part number 30713416) with an internal ignitor can be retrofitted. We are currently working on a plug and play harness for adapting these coils.
Burbles/Crackles: This feature retards timing and increases fueling when the car is coasting with no throttle input. This will cause popping and banging from the exhaust. Anything other than a straight through exhaust will muffle the sound, sometimes significantly.
Alternate Mapset: A second map set, allowing you to switch injector calibrations, fuel map, ignition map and boost maps on the fly, without the need to flash a new tune. Usually this is used for a gasoline and E85 map, but can be used for water methanol injection or a high performance and high fuel economy map.
VVT Control: For those running RN engine with single or dual VVT control, this option adds open loop control of the VVT cam solenoids to the ECU, vastly improving the width of the powerband. In order to run dual independent VVT control you must run wideband lambda regulation and COP. VVT connectors are added to the COP loom when ordered at the same time as the COP add-on.
Boost Control: Since the 960 M4.4 was originally designed for control of NA engines, it has no provision for the control of boost using an electronic turbo control valve (TCV). If you wish to have the ECU control boost, the rear O2 circuitry can be repurposed for this function. Boost control will be open loop, determined by pedal position and RPM. Wiring of the TCV will require splicing into the rear O2 sensor wiring. Dual VVT control and boost control are not possible simultaneously.
Launch Control/Anti-lag: This adds a routine which will trigger when the car is stationary and the throttle is fully floored. The routine can be configured as anti-lag, which will generate significant engine load and allow the engine to be launched will more power from a stop. It can also just be used to show off, and will shoot flames out of the exhaust. Anti-lag can be quite hard on an engine, so its use may lead to engine damage. Alternatively, the routine can be configured just as a secondary rev limit, which can be useful for dialing in the correct launch RPM.
Wideband Lambda Regulation: This option removes the stock O2 sensor, and instead uses the signal from a wideband controller to control closed loop fueling (STFTs). You need a standalone wideband gauge/controller to interface with the ECU, the AEM X-Series wideband is highly recommended. Please see this link for more information.
Multi Purpose Output: Adds a ground switched output to the ECU which can be triggered based on boost, engine load, RPM or any other ECU parameter. Useful for turning on a water methanol system, shift light or NOS solenoid. Unless your car is a 1998 you will need to wire in a relay to control whatever external device you wish to trigger. 1998 cars have existing circuitry that can be repurposed for this purpose.
