    Free unrestricted maps for Rocket R GT and TFC now online

    Ah sorry, now I got you. Yes, when the ECU is first programmed, calculated values are used for the fuel injection. The amount of air in the cylinder is determined, and then the fuel quantity is calculated according to the desired AFR value. That’s enough to get the engine running reasonably...

    Free unrestricted maps for Rocket R GT and TFC now online

    Maybe we have a misuderstanding. The value in the AFR-map even in the closed loop area is not part of the fuel calculation. There is no 10% increase in fuel if you change target from 14.5 to 13.1. That is different from the Delphi ECU where AFR tables are part of the calculation even outside of...

    Free unrestricted maps for Rocket R GT and TFC now online

    Yes. Just changing fuel tables with an active O2 sensor and AFR-tables left at 14.5 will definitly be overrun by the ECU. First by the short term fuel trims temporarily and then by the long term trims finally. You have to disconnect the O2 sensor or change the AFR-target to prevent that. Fueling...

    Free unrestricted maps for Rocket R GT and TFC now online

    You´ve got me with your last question. I always wanted to check on that. My understanding so far is, that anything but 14.5 in the afr-tables means the ECU quits adjusting. But I have heard that it works up to 14.1. The main difference between the Harley/Delphi and the similar Indian/Bosch to...

    Problems after tuning or coincidence?

    No. Unless you put in another camshaft, tuning does not cause any trouble to the tensioner.

    I have a Storm '25 model and ordered BT Moto ECU read/write gadget

    I am not involved in the development of the tools. And I think it is very unlikely that Alain will come up with Tune-ECU for the newer models. Since Triumph does it all online the game has changed. But BT-Moto still does the job. In the long run an aftermarket ECU will probably be the only way...

    I have a Storm '25 model and ordered BT Moto ECU read/write gadget

    Sounds loke they did a good job. The lower the revs and the throttle opening, the more the lean stock 14.5 afr becomes an issue. A decent map is not just about wot.

    You got it right. Just give it a try.

    Eka's Pretty TuneEcu Maps

    It is two spark plugs per cylinder and low revs. These are some dyno runs with the 2.3 Rocket with different ignition advance. (Torque in Nm) ("Zündung Grad vor OT" is ignition degrees BTDC) There is no need for big advance numbers. It just puts stress on the engine. But I agree that at lower...

    Decat Pipe. Do I need a tune?

    The unrestricted map will work with the decat. It will probably run too rich in the low revs. But that won´t do any harm. Mid and high range will be good. As the O2 sensor is mostly deactivated to not interfere with the improvements, it will not be able to make any adjustments.

    I've noticed with the Rocket.....

    My advice would be not to give af.

    US penner tune for 2022 r3 GT

    Not sure about the actual conditions when you purchase Tune-ECU. But if you once got the map loaded into your ECU , it will stay there and won´t reset to stock after one year. Just make sure your dealer does not make any updates.

    Thinking about getting the BT moto tuner for my 2025 rocket

    I am pretty sure, that the BT-Moto Tuner will do a good job. Being the only ones to get into that ECU is by far the hardest part.

    Unrestricted Map 31248 all markets for Rocket 3GT/GT Black from VIN AV5457 ETV/F/Afr Tables modified 7400 Rev limit

    Easiest way is to connect your bike to Tune ECU. It will show the number of your stock map. Then look for the corresponding map at Tune ECU custom maps section. I am pretty sure I made one for Australian market. As far as your exhaust is concerned you should do at least a dyno run and watch AFR...

    Werkes Exhaust on UK bike ?

    Since Euro5+ it is common to have two O2 sensors before/after cat. You can weld in an adapter for a second sensor. Not that big of a deal. Tune ECU won´t work on the Storm models.

    I am working with Woolich software on Japamese sport bikes. They are doing a good job and also have a great wprking autotune function.

    Paul Bryant full system for 2.5 R3

    If you don´t like the popping, set the 0% column in the ETV tables a little higher from top to 1500rpm. Engine break will be reduced a little, but you might even like it. Prost Ulf
