    EVOscan Throttle position sensor voltage on evoscan

    The ecu uses 255(0xFF) for the max TPS value(5 volts).For % you would use: x*100/255For Volts you would use: x*5/255 or x*0.019610.01952*x, is very close, but might be off a millivolt or two.TPS RequestID is 17.

    What ECU do I have?

    Many of the flashable ecus are interchangeable.The 4 cylinder H8 ecus are divided into two groups: Emissions compatible / USDMNon-emissions / JDMA rom from the same group will most likely work in an ecu from the same group.But there are some hardware differences that cause...

    Big H1C (hx35) Spools to fast causing surge?! help!

    Enable boost control.If you can do boost by gear, just lower boost at lower rpm and affected gears. (Where you are having surge.)Compressor surge is caused by the turbo spinning up to fast and crossing its surge line, not by back pressure. Although a larger hotside will slow down...

    98-99 ecu in 96 GST

    I have not tried it myself.People report they get low rpm engine vibrations and knock.Its kind of hit or miss if it works or not.You could swap a 1G CAS on, but I believe the 95 camshafts need the passenger side threaded to accept the 1G CAS.A 97-99 would also work but I'm...

    98-99 ecu in 96 GST

    98/99 ECUs don't play nice with 95-96 Inverted CAS.1G and 97-99 CAS work, but not 95-96.

    The 1Gs get their crank signal from the CAS, there is no separate crank sensor like on the 2Gs.

    98/99 Ecu tuning problems

    Its strange that you need so much MAF compensation. Usually you just need to enter Injector Scaling and Latency and you are good to go, MAF Smoothing is more just for fine tuning. Is back up with pics. But I need to update some things, mostly the Fuel...

    98/99 Ecu tuning problems

    MAF Smoothing adds or subtracts fuel at different Hz levels.It has a nice % scaling.So 110% = 10% more fuel.I prefer to use MAF Smoothing to adjust fueling.And use MAF Scaling for swapping to a Evo or other MAF.

    ECUflash Help me with a base map so i can take my car to the dyno! (ecuflash/ceddymods)

    Take your gas injector scaling and divide by 1.49.Say you had you 1600s scaled at 1400 on gas.On E85: 1400 / 1.49 = 940So new scaling would be 940.Latency/DeadTime should be the same or very close to your gas settings.

    cyclone intake manifold parts

    If you use a fpr solenoid and ecu control (or rpm switch) you need a vacuum canister.Some people will mount a wastegate to control the Cyclone, by boost. But it is most effective when activated by rpm.The stock rpm activation on the Galants(?) was 4100 or 4300. On DSMs most activate...

    Force OBD Inspection Pass 2G

    You don't want every test to be "Passed", as the DSMs don't support all the tests.It might look strange to have "Passed" for equipment that was never present from the factory. A few of the tests should say "N/A" or "Not Available".I'll try to find some of my old notes for which tests...

    The big drawback to a 2G Ostrich is that there isn't much open source/free support as there is for the 1Gs.Another draw back is the logging on the 95-96 is very slow. The best option is using EvoScan and the MUTOverOBD2/Hybrid option, but sample rate is still limited to less then 10 samples...

    One major thing that the Mitsu OEM based EMS (DSMLink, EcuFlash, Jackal, etc) have that Standalone EMS don't is the Knock Control System.Standalone EMS tend to try to integrate the Mitsu Knock Sensor by simply looking at Knock Voltage. This isn't adequate, you can have zero knock at 5 volts...
