The first number refers to the viscosity of oil in the engine when cold. The viscosity of engine oil is generally specified as a number, letter, number on the container, Like this: If you adjust your TPS position on the throttle body obviosuly you need to redo your calculation.Įngine Oil / Oil Temperature / Oil Pressure The only variable is x which is raw throttle position from the ecu.Your TPS value in the logging window now reads 0 to 100 % if you did it right. So just doubleclick on the value in the datalogging window and enter the formula into the eval field. So now we need the formula (( x - Tc) / D) * 100 Now subtract To - Tc -> 255 - 36 = 219, lets call this value D = 219 Press the pedal all the way to the floor and The engine off and then flip the ignition back to the on position With the car running and your foot off the throttle look at throttle Updating the EvoScan Formula to get a perfect 0-100% throttle position value for your vehicle. MUT50 = Copy of the trim currently in affect

MUT0E = LTFT_High (Usually not used, but that's what this MOD is all about) You can log MAFHz with MUT1A (x*6.25) and then you should be able to see when the STFT drops to 0% (closed loop)
You should be able to see the trim being used by logging MUT50 - same formula as the other trims. Primarily on feedback from, the oxygen sensor to determine if the stoichiometric air/fuel ratio is being maintained. Once the vehicle is running and the engine control system enters closed-loop, the PCM relies Injector Pulse Width = (RPM × MAP/BARO) × TPS × ECT × IAT × Battery Volts × O2 (Short Term x Long Term). The equation used by early Chrysler speed density OBD II vehicles to establish initial pulse width is: HOWTO: Enable Readiness for OBDII inspection after removing your o2 sensor
