- block is now a S
- pickup will be VR on a 60-2
- COPS (Coil On Plug)
- cam trigger at some point but not yet
- use 164 intake(cut to fit) with the longer runners tuned to the S cams
- 179.91CID 2.949L
- stock injectors 18LB
- Req_Fuel 17.5ms
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

Injection
using old wires
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!!!

| TPS switch (need to get a motronic pot type) | ||
| L-jet Pin | Wire Color | Use |
| pin#18 | Purple | common |
| pin#3 | Yellow | WOT |

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
l-jet pin#34 Orange will be the IAC control
it looks like l-jet pin#28 Yellow/red need to go to ground to enable the S2 double relay
l-jet pin#4 Grey/green looks to high while cranking and will power part of S2 fuel pump/O²
l-jet pin#20 Pink/black looks to power S2 fuel pump/O²
l-jet pin#1 coil also goes to cluster(tach?)
