    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...

    ECUflash First Flashed DSM ECU! (98/99 Flashing FAQ)

    Yes you need to flash the CeddyMod rom.MUTIIIMUToverobdII is for 95/96s.

    ECUflash First Flashed DSM ECU! (98/99 Flashing FAQ)

    EvoScan data.xml is in the CeddyMods .zip file.In EvoScan_2.7+ folder.No need to setup MUT Table, 2-Byte Load, etc.Its already all done for you. :)Edit:Didn't see you have EvoScan 2.6. For that version its in EvoScan_2.6- folder. Upgrade to at least 2.7.0090 for working Maptracer...

    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.

    where is crank sensor on 1g

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

    ECUflash Need the 98 AWD definition file/ROM for ecuflash

    http://ceddy.us/h8-ecu-wiki/roms-ecuflash-defs/2056-0008 and 2056-0010are both there for download. (2056 is 98 AWD)But your stock rom may be a different subversion. There are about 5-10 different subversions for every year.Most people just use a CeddyMods rom, you can...

    ECUflash CeddyMod v1 (EcuFlash)

    You can't run a GM MAF without out a Translator.The GM MAFs frequency output isn't compatible with our ecus.Even with DSMLink you need their cable/translator.

    safcII or ceddymod

    All DSM Plastic Case ECUs are Flashable.The only exception that I know of are some early ACD(Active Center Differential) ecus must of been a prototype run and have a Hitachi H8/539 cpu, not the Mitsubishi variant of that cpu.The H8 ecus(98-00 or 01) can come with the MH7202F or MH7203FA...

    4g64 dohc s16g logs

    The stock EvoScan EcuLoad will only go up to 160. Which is only around 7 psi.If you switch to a CeddyMod rom, and use the included EvoScan .xml there are addition Loads added to log.1Byte Load is the best(fastest) to log.[1Byte Load maxes out at 320 Load, ~30 psi]A few of the...

    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.http://ceddy.us/tuning/injectors/ 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.
