data upload in progress... First Honda b16 engine with vems in hungary? built for drag race b16a2 engine forged rods, pistons darton sleeves garett gt35 turbo etc. http://www.vems.hu/files/tbiro/vti_turbo/20200213_180706.jpg http://www.vems.hu/files/tbiro/vti_turbo/20200220_180442.jpg B16 engine has 3 VR trigger in the distributor. 24 - 4 - 1 teeth coil types. 24 and 4 triggers works fine but the 1 teeth trigger make lot of trigger error( I think asymmetric circle design may be the problem, generates magnetic field incorrectly, tried to build some resistance, could not worked. So the 4 teeth trigger wheel machined to 1 teeth) http://www.vems.hu/files/tbiro/vti_turbo/20200305_164200.jpg http://www.vems.hu/files/tbiro/vti_turbo/20200222_105048.jpg ------------ PINOUT INJ1 BROWN INJ2 RED INJ3 BLUE INJ4 YELLOW COIL1 yellow COIL2 blue COIL3 red COIL4 brown CRANK CAM TPS RED/BLUE IAT RED/YELLOW CLT red/white FUEL P green/yellow MIL green/orange 5v OUT yellow/red FAN nincs GND 5V yellow/black VTEC solenoid green/yellow GROUND black 15+ ckpp blue solid ckpm white grey dot tdcp solid green tdcm red grey dot cypp yellow cypm black grey dot iac blue/black pcs red icm1 yellow/green gnd lg1 brown/black gnd lg2 brown/black 12fix/vbu white/blue ------------------------------- oem pinout comment: ACC - A/C relay ACS - A/C switch ALTC - Alternator relay, for control purposes, not present on all ECU?s ALTF - Alternator switch BKSW- Brake switch, for control purposes, not present on all ECU?s CKP - Crankshaft position, (P)ulse or (M)ass, gives several pulses (~20?) during each cam shaft rotation CYP - Cylinder position, (P)ulse or (M)ass, gives one pulse during each cam shaft rotation DLC - Diagnostic connector, communication signal to the 3 wire connector next to the SCS connector ECO - Unknown function (is there an ECO light on D15Z3?) ECT - Engine coolant temperature EGR - Exhaust gas recirculation EGRL - Unknown function (probably related to EGR) FANC - Fan relay, for control purposes, not present on all ECU?s FLR - Fuel relay, 1 is always present, 2 can be ignored IACV - Idle air control valve, controls the 2 wire type IACV valve IAT - Intake air temperature ICM - Ignition pulses, 1 is always present, 2 can be ignored IGP - Battery feed, only active when key is turned INJ - Injector, the number refers to the cylinder used (1 is on the side with the belts) LG - Ground for battery circuit MAP - Manifold absolute pressure MIL - Motor indication light, this one gives the control engine light (CEL) signal PCS - Control solenoid, this one is for the small black cylindric valve on the back of the IM PG - Ground for battery circuit PO2H - Primary oxygen sensor heater, connects with the ground of the car to activate the heater PO2S - Primary oxygen sensor signal SCS - Service connector switch, checks if the SCS connector is hot wired (for reading engine error codes) SG - Ground for 5V circuit, 1 is for the MAP sensor, 2 is for the other sensors STS - Starter switch TDC - Top dead centre, (P)ulse or (M)ass, gives four pulses during each cam shaft rotation TPS - Throttle position signal VBU - Back up battery feed, always active (unless battery is removed) VCC - 5V feed, 1 is for the MAP sensor, 2 is for the other sensors VREF - Unknown function (probably related to wideband oxygen) VSS - Vehicle speed sensor VTM - Oil pressure switch, only -but not always- present on VTEC equiped vehicles VTS - VTEC solenoid, only present on VTEC equiped vehicles ------------- still under construction testing now.. -------------- I have problem about trigger signals. I need help. The iginition system converted to COP. We have 3 signal on the camshaft/distributor (all of them coil types (VR)). First wheel has 24 teeth (use this for primary signal) Second wheel has 4 teeth (not in use) Third wheel has 1 tooth (use this for secondary signal, cam sync) In my theory, the ratio of crank and cam is 2:1. So we need to calculate the 24 teeth to 48 teeth for a full engine cycle. But when I get the 48 teeth by cam, I get two secondary signal too... http://www.vems.hu/files/tbiro/vti_turbo/trigger.jpg http://www.vems.hu/files/tbiro/vti_turbo/v3.3_u014084-2020-03-13-17.09.18.triggerlog
