I have a couple Pro8s and PMU16s sitting in a box waiting for their vehicles to be ready for them. I’ve spent the last 15 years using a different management family and am preparing myself for the switch to ECUMaster. I’m in a position right now where I have a very stock engine mounted in a car and feel like there is no time like the present to attempt a very basic ECU swap. The current ECU is a batch/wasted spark setup running off of a 36-1 crank trigger wheel. My plan is to build a simple adaptor harness to the into the existing one. I have the hardware to make that easy, I really just need to know if I’m going to get into trouble if I try to connect 1 injector channel to 2 or 4 injectors. I think right now I’ve got 2 injectors per channel on the existing ECU.
I couldn’t find any settings that allowed me to assign two cylinders to a single injector channel. Do I need to do anything special in the software to make this work.
My goal here is to be able to test the new electronics on a basically indestructible setup in order to familiarize myself with the new software and hardware. Eventually the car will get all of the bells and whistles it deserves.
Hi,
Yes, you can have multiple injectors on a single output.
You assign injector outputs to cylinders. So you can assign the same output to multiple cylinders.
We are currently missing a setting to tell the ECU that there are multiple injectors on a single output. To work around that, you have to multiply the injector reference flow by the number of injectors on a single output.
Thanks for the quick response! Based on that, is this what I should expect to see? It looks like it doesn’t love me selecting the same output for different cylinders. Does it just turn red to bring it to my attention, or will it not allow it to work while configured as such. When I look at the assignments page, it says there is a conflict. Ignition outputs are configure just like the injectors, but they happily group up, and recognize the intention.
Yeah that’s to draw your attention to it as a possible issue. As Mkuklis said the batch injector’s need a feature added, but wastespark is covered in the current software.
Black/Classic do the same but the output will operate if either assigned function tells it to.
As long as it will run while having an internal conflict I’m fine with it. I just don’t want to hook this sucker up and have a car that needs to be completely rewired in order to run.
