Re: Tune development

Values are named KQFULLDNI and KQFULLDNP, and are right before KQFULLDNTHEX_S (what should be EGT limiter 790 deg. C - THemperature EXhaust). It is possible it was badly scripted before.

Of course old tune over rail pressure, not the new one over start of injection.

Re: Tune development

Another curve, Stage 1 Performance, Torque Limit Per Gear is mistaken, it's table named TREV_OFS_REVCTL_D and it is in RPM not Nm. X values are marked GEARP_REV, which seems to be gear, but from name and units it looks like some offset in RPM.

Re: Tune development

I made some checks and according to WinOLS project with Denso "DAMOS" mapping I provided to Ugnius there's problem with table "The boost limit based on boost air temperature. This is to prevent excessively high air charge temperatures or operating the turbos far outside of their effic...

Re: ECU Calibration

You're just joking, 240 records out of 12186 are APP_REL > 90. But about runtime 370 you can see constant APP 94.12 with BOOST_A_STATUS suddenly switched from Closed to Open. But from my POV, I've seen more oscillations with clogged intake/MAP sensors.

However unusable (very few lines when filtered to load>90 and full throttle). In addition, it is necessary to log time since engine started, revolutions per minute, vehicle speed and accelerator position.

Re: ECU Calibration

Now I have my boost pressure lower than desired - Manifold Absolute Pressure is 20-40kPa lower than Manifold Absolute Pressure Desired. In some conditions (high load, high RPM) its almost the same (my VT logs in attachments). Also during regeneration its the same. IMO is it perfectly normal, during...

Re: DPF issues after Remap

SH engines run very hot, with the Versatune tuning even hotter, the DPF burns spontaneously. There is generally no problem with DPF with this engine.
