I guess I cut that in half 8.75ms

I changed the coil mosfet resistors to 1K (feeding the Base)and put in PNP 2N3906

at Q3 Q6 Q9 Q12 Q16 Q21

Emitter to power Collector to the outputs


COP setup

The pairs I will use so I can run wasted is
Transistor number in setup ECIII pin
Q16,Q21 #0,#1 pin35,pin33
Q6,Q9 #4,#5 pin11,pin12
Q12,Q3 #6,#7 pin10,pin24

Injection

Using old wires.

I need to look at the car but the diagram out of the online books page E-43

each injectors has a red wire for power via S2 relay looks UNFUSED!!!

To ECU

L-jet Pin Wire Color Injector #
pin#31 Light-blue/yellow 6
pin#30 White/red 5
pin#14 Light-blue/red 4
pin#32 Yellow/black 3
pin#33 Orange/white 2
pin#15 Green/white 1

on my car the 87 seems to use different colors or aged colors

TPS

TPS switch (need to get a motronic pot type)
L-jet Pin Wire Color Use number in setup ECIII pin
pin#18 Purple common TPS pin2
pin#3 Yellow WOT TPS5V pin28
pin#2 White idle GND pin26

IAC

will use the same pins the powered the heater in the old thermo type

one pin goes to the S2 power fuel pump/O² Orange/black

need to add a flyback diode between the pins.

L-jet Pin Wire Color Use number in setup ECIII pin
pin#34 Orange will be the IAC control INJG pin6

S2 Relay enable

it looks like l-jet pin#28 Yellow/red need to go to ground to enable the S2 double relay


Fuel Pump/O² Power Control

l-jet pin#4 Grey/green looks to high while cranking and will power part of S2 fuel pump/O²
