4th gen 3SGTE Toyota engine started (thanks to Marcell support). So made some progress, but generates trigger/wheel errors.
Same kind of V3.2 ecu runs succesfully in couple of BMW's (these have slightly larger trigger wheel and different sensor).
Differences between installations (VR/triggering vice).
- firmware 1.0.19 (in BMW) for sure ?
- and 1.1.18 in Toyota
- VR sensor (510 ohms in BMW) and 1372 ohms in Toyota (oem sensor)
- trigger position (100 deg in BMW) and 95 degrees in Toyota.
VR condition circuitry voltage level (from sensor) might be lower in Toyota installation.
in Toyota we have...
60-2 trigger wheel
diam 158.1 mm -> circular length 496,6858 mm
1 deg = 1,379683 mm
90 deg = 124,17145 mm
Toyota OEM VR sensor resistance 1372 ohm, measured median 0.72 voltage at around 1000 1/min (engine idling).
Trigger tooth = 5
Next trigger tooth = 30 (NOT 35 !!!)
Crank min period 1808 usec (you can safely use 0)
Reference tooth table h(1)= 1E 00 1E 00 <-30 0 30 0
Shielded cabling used (grounded only at one end).
Filtering and Advanced filtering was tried enabled and disabled -> it didn't help, but tooth normal/missing relative minimum and maximum didn't tried to change. Values are 'by the Megatune F1 help'.
Tooth Normal Relative min% 31
Tooth Normal Relative max% 144
Tooth Missing Relative min% 213
Tooth Missing Relative max% 388
VR sensor polarity is checked (how?), also signal and its shape is good.
VR signal DC bias ? Measure DC voltage with DVM. Use a 18..22k pullup to +5V. Although this should not matter for normal running (only at cranking)
Any idea ?
Should we change sensor, solder/change some ecu components or try some setting values ?
Could somebody check our tooth_twidths and other triggering/filtering etc. related settings.

Other problem is that Megatune somewhat messes some settings and values in h(0), h(1) and h(2) table -> so made them by hand and downloaded separately.
in h(0) table four leftmost is used, zeroed others by hand and uploaded tables to ecu. Started Megatune opened h(1) table setting page and sent to ecu. Values 5D and 6A appeared mystically.
Same happened in h(1) (E3, B7 values)
Also...
When downloaded tables from ECU -> to tables.txt file, made edits with Notepad and did generate config with generate_config12x12.bat
Warning: table t has less than 8 items
Looked our tables.txt (which in a first place was downloaded from ecu), only to find that it did not contain t() table at all.
global.h (version 1.1.18) was in same directory root /firmware/ folder -> verified it's version and location against config.bat.
