Hey everyone,
I am just wrapping up a 24x conversion from EFI Connection that I did on a friends 1987 Iroc-Z camaro with a SBC 350. Its using a 411 ECU from a 2002 Silverado.
I had some thoughts and wanted some feedback on the way I did a few things as well as a couple things I haven't tackled yet.
For the firing order issue I decided to swap the injectors and coils for 4 <->7 and 2<-> 3. This worked fine until the O2 sensors started correcting and I ran into an issue that now the 3rd, 4th, 7th, and 8th cylinders in the firing order are on the wrong banks the trims were inverse of each other and got into a weird loop where I eventually shut it off because they were fighting each other. I went in and modified the cylinder/band assignments and that seems to have fixed that isue.
So first question is would I have been better off in just changing the firing order under Engine -> General and wired coils and injectors to the correct cylinders instead of swapping them around? I feel like if I did that then I wouldn't have ran into the O2 sensor bank assignment issues.
Just want to make sure I am understanding and learning about thing correctly.
Thanks,
