I am trying to install my MS2 so that I can swap it in and out with the stock fuel injections system easily since it is my daily driver. The stock injector harness has a 2 prong connector to disconnect the stock ECU. I would like to wire MS2 to utilize the stock plug for simplicity.
My question is; how do I wire all four injectors on a single bank using only 2 wires. I know I wire power through one wire but should I ground the injectors through both injectors banks on the MS2 ecu and run simultaneous batch injection in the software? Normally I would wire power to all injectors and ground 2 injectors to one bank and the other 2 injectors to the other bank and run alternating injection.
Thanks for the help

Re: Single Injector Bank Wiring Question
What resistance do you read between the two pins going to the injectors?
Re: Single Injector Bank Wiring Question
The resistance reading at the connector is 3.7 to 5 Ohms.
Re: Single Injector Bank Wiring Question
If the four injectors in parallel are reading between 3.5 and 5 ohms, then they're high impedance, and you should be able to drive them all off of one injector output as-is.
Kind of makes sense, since if you were running a multi-port V8 you'd need to be able to run the two banks like this.

Re: Single Injector Bank Wiring Question
So I don't need to tie in the other pins for the second injector bank? or in other words I can leave pins 35 and 34 disconnected and only use pins 32 and 33 for all 4 injectors?
