add variable block sizing for troublesome Mitsubishi CAN vehicles.Later processors like the SH2 and M32R generate this reflash voltage internally, and have minimal current requirements, which is why the Openport 1.3 works with the Evo 7/8/9 without a problem. The Openport 1.3 does generate a voltage large enough to cause the processor to startup in boot mode, which is why you could read and compare in past versions, but unfortunately, it just isn't usable for reflashing. The reason being that the Openport 1.3 power supply circuit that generates the ~16V the ECU needs to supply the regulated reflashing voltage to the CPU does not have a sufficient current capacity, causing this voltage to drop to levels insufficient to safely flash the CPU (the CPU goes into a protection mode to prevent you from even trying). we will not be able to release a version of EcuFlash for the Mitsubishi H8 processor family of ECUs that works with the Openport 1.3.add support for EVO 5/6 and other Mitsubishi H8 reflashing.increase maximum allowable ISO9141 baud rate to be 125000 baud.fix bug where resting voltage of adjustable power supply can be low enough to trigger undervoltage protection of voltage multiplexer IC.fix bug which can cause CAN receive buffer overruns during large ISO15765 transfers.(no changes other than new firmware payload).fixed bug in Subaru K-line reflashing that did not initialize the parity mode of the vehicle interface, causing errors if the interface had previously been used with odd or even parity.fixed error that limited data type to 4 bytes in size (doubles and bloblists can be bigger).this allows ROMs of the same version to be shared amongst users without refusal-to-flash errors. allow unique ID data in Subaru CAN ROM protected area to be different without requiring this area to be reflashed (which is not allowed).add some retries to kernel reads, instead of failing.actively pull up OBD pin 9 when communicating with HC16 Subarus to avoid reflash mode initialization problems on some EDM models.fix programming voltage warning errors in Subaru HC16 kernels.up to Generic2048K, including all powers of 2, plus many other common sizes. add many generic memory models to allow support for arbitrary ROMs from ECUs that EcuFlash has no flashing support for.support for flashing H8/539FA processor (e.g.We tend to do all the development on our own bikes, this means we can spend as much time as needed to get the data we require and also test different modifications on the bike to understand how they will effect engine function. As we’re all petrol heads at BHP UK it also means we have nice fleet of bikes to ride and test at weekends. We will run and monitor the bike in all the engine modes available thus building a complete picture of the bike’s standard mapping. On many occasions we find that the manufacturer has restricted throttle opening or imposed torque limiters in the mapping in an attempt to sedate power delivery or meet emissions standards.

The data we collect gives us an idea of how the manufacturer has set the bike up and where improvements are possible. Some of these parameters we can log through the bike’s OBD while others will require external analogue output sensors. We also need to take other measurements including, throttle position, spark advance, throttle plate position, knock detection, engine oil temperature, engine coolant temp, exhaust gas temperature and injector duty cycle. We use our Dynojet 250i to run the bike and measure power output. We will attach our own lambda sensors to monitor Air Fuel Ratio (AFR). When we develop a remapping strategy for any motorcycle we will run the bike on our dyno and monitor every possible aspect of engine function. Remapping will save the expense of buying a tuning module or “piggy back ECU”.Whenever a bike is modified with aftermarket upgrades such as an exhaust system or air intake is essential to remap the ECU to ensure the engine is running correctly.Īll our remaps are developed in house by us at our fully equipped facility in the UK. We do not use base maps from other companies and simply tweak them to run on your bike. Many bikes will have the power restricted in certain gears and certain engine RPMs to meet increasingly restrictive emissions regulations.ĮCU remapping is the science of altering the parameters in the ECU to make the engine run optimally. The ECU will also have torque and power limiters to limit the power produced in certain situations. The Motorbike ECU (Engine Control Unit) is now a very sophisticated computer and controls every aspect of engine function including fuelling, spark advance, throttle plate opening and closed loop lambda monitoring. All of our remaps are developed by our in house team of map writers.
