The engine is actualy running on lower rpm than ecu shows . For example engine running around 2K the ecu shows 3500 and aroun 3K hits the rev limit because the ecu thinks it is on 6000 . But the strange is that engine is running verry smooth . Now i tried to move from 5v to 8v supply to sensor but i have no readings . Now on 12v supply on sensor i have the same result . I`ve upgraded the firmware to 5.5.7 but nothing . On lower filtering i have bumps on rpm readings but on level 4 are correct only on the low RPM. Sorry about my bad english . Is there any special setting for this trigger its 24tooth with no missing i think? And is there any way to fire it with custom settings using multitooth ?
The rpm is measured by stroboscope . I have tested it on my bmw running on megasquirt wasted spark mode and reads correct . We have build another ls1 swap but with ms2+some signal converter and other engine revs up to 6300rpm and it sounds double compared with this engine .
Thank you

Hi everybody. I have problem with rpm readings of 3gen LS1. The problem is that on starter and low idle readings are correct . But on high rpm is mismatch, for example the motor is running around 2k but the tacho reads around 3500 on 4k reads about 6000 rpm . I have selected LS1 3-12 and 5-10, LT1 , multitooth triggers and tried different filtering but there is no change . The car runs smooth afr is constant the only problem is the RPM readings .
ecu: Link G4+ atom 4 cylinder wasted spark mode
crankshaft position sensor is connected with 5v Power supply .
GM LS1 RPM mismatch SOLVED
in G4+

Problem solved . Thank you Rich RDE i hooked cam trigger with default ls1 settings +12v to cam and crank, Trigger1 Chev LS1 3-12 Rpm filtering 4 and Trigger 2 settings Optical/Hall Level2 filtering triger 2 pullup ON and Trig2 edge rising .
