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 -> read now, had.
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 wheel was little bit too small, for the OEM sensor - which caused triggering errors in higher revolutions. Lasercut slightly larger 215 mm wheel.
To someone reading this in distant future. One might to try Toyota oem VR sensor with Toyota oem (32 + 4 type) wheel mounted under crankshaft front pulley with future VEMS firmware version. We tried it with firmware 1.1.23, but the wheel type was unsupported (or at least did not work).
Trigger tooth = 5
Next trigger tooth = 30
Crank min period 0 usec
Reference tooth table h(1)= 1E 00 1E 00 <-30 0 30 0
Filtering disabled.
Shielded cabling used (grounded only at one end).
VR sensor polarity is checked (how?), also signal and its shape is good. Checked polarity by moving mild steel plate towards the sensor and continuing moving piece away from it.
Correct VR sensor connection (polarity);
DVM reads positive voltage when plate comes to sensor tip and negative voltage when plate was moved away from tip.
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)
Yes, the VR sensor voltage was 0.15 volt positive biased because of too small trgger wheel. Actually tooth/space ratio too small.
