Hi knowledge pool.
I’ve restored over 30 cars/bikes but the first time I’ve delved into the dark world of EFI .
Factory setup is:
- Vacuum advance / retard distributor
- Cam driven fuel pump
- NormalAir (Garrett) T3
- Stromberg CD175 (draw through setup)
Modifications:
- Magna (Mitsubishi Diamante) Hall effect distributor with Cam & Crank sensors
- Electric fuel pump & adjustable regulator
- “LS1” Coil
- Patton Machine CD175 adaptor with side entry TBI Injector.
- AEM 30-0300 wideband
- TPS
- Air Temp
- Water Temp
- MAP
I started the project late 2022 and had it in and out a couple of times as I had to put it back to standard dizzy & carby setup to get to race meets.
So here is hoping you guys can throw an eye over the setup (I’ll attach files) .
In my latest attempt I have added one piece of the puzzle at a time & got it to the point that I have had it running on everything but the adaptor, ie; still with carby.
I have tried Paired & Sequential, 1&4 injectors, different ‘dead time’ settings but it won’t fire let alone run.
I have confirmed that the injector is pulsing with the aid of a Noide light.
I ran out of battery so my next test will be to sit the adaptor in a glass bowl and crank it to see what sort of flow is happening…….
Thoughts from the gurus??
*EDIT* - I tried to include hyperlinks to parts but the forum doesn't seem to like that....
