Advice on lq9/243 with 8.1 injectors
I’m looking to see if I could just use a lq9 timing tables, and scale it down say 5-6 degrees for a starting point, seeing im basically a iron ls2 now. I looked at some ls2 files and I can’t copy seeing the kpa is different and the graph layout.
Second part is these damn 8.1 marine injectors, searched for data and have had minimal success with information, everything’s seems to lead to tuning them in. Some say 41.6 flow data, will work. Some say 43.8 with min pulse width of 3.921. list goes on
any info would be great- I’m using EFILIVE

Once this silly Michigan rain breaks... hopefully can take it out for some logs... got idle pretty good, the link is on cold motor still... afr changes once above 180 degrees

Not saying you’re doing it wrong it’s just I’ve never seen it that high.
