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...

Tried samples like 4cyl_c024, 4cyl_12+extra_Honda_K20AX_Camsync and others..
I got secondary trigger bad position or less primary trigger errors.
