1942 Jeep GPW with Ford 2.3L Lima

ME:
I am semi retired from the high tech world of 40 years, EE design engineer, Engineering Manager, Program Manager, engineering support for laptop development, smart phone developer and design support, so i am know the laws of Ohm. Also a firmware engineer in my past, and led Intel Core Firmware development for 3 years.

This project is a learning for me and my son of 20 years- i have an LS swapped JK jeep, and this will be his toy once we get it rolling.

My rig:

i have a WW2 jeep that somebody converted to a 2.3L Ford Lima, little known fact the Most jeeps of WW2 were built by Ford, then Willys and then Bantom.

the 2.3L was converted from carbureted 1985 Mustang to EFI, EFI harness is a 1987 Mustang and I assume the injectors and manifold as well. I did see a video of the jeep running before it was tore down and screwed up.

Harness is garbage, somebody ripped it off the jeep to sand blast it and that is where i got it. So to "simplify" i am starting over with the RusEFI uaEFI unit.

There is No Crank position sensor, only inductive pickup off the distributor. Per a suggestion i am splitting the disti coil to D585 (ls3) individual coil packs.

Since there is no wiring I am starting from scratch, so thinks like Main 12V etc.. don't exist unless i put on the relay and since it was never a true EFI this is a frankenstein for sure.

Wiring as of 7/5/24
***********************
Connector A8 right now I am just connected the 12V main straight to fused battery. (i now see this delayed from 12V ignition so I am off to change that)

Connector A7 is Switch ignition 12V

A3-A4 are routed to fuse block I am building out and tied to battery Ground.
*********************

Descriptions on connectors are a PIA to interpret but i keep reading and reading.

Questions right now are:
without a Crank position sensor I expect i have to do Batch Firing on the coils?

injector firing can be trained?

I don't have a Hall input , it is inductive pickup I think it is VR reluctance. Do i have to change the RusEFI board for inductive pickup on Hall 1? or is there another Hall input that is already inductive pickup? Hall 1-3?

Finally LED diagnostics.. where do I find what the board LEDs means, looked several places and no luck for me yet?


thanks, Dennis

yes, without _cam_ sensor it's batched which is fine

not sure what is training injector firing.

[orviston]

Thanks for confirming, I thought I read elsewhere that you can train/or some how align the injectors through training. obviously I haven't done this.

I will ask it this way.. with Cam sensing how does it know when to enable each injector.. or are they batched as well?

LED indicators? Is there a document for their meaning - can't find them.


thx, Dennis

On my setup, the injectors are not sequential while cranking. This is a "cranking" setting in Tuner Studio.
I have a 1994 2.3l ranger (oem ecu). Lima power!
