I am running the COS 2.5 tune w/ ID1000 injectors therefore I have my stoich set to 29 which would equate to 14.5. Doesn't look like you can run fractional numbers. I run E10 which stoich looks to be closer to 14.1. so am I better off changing the stoich value to 28? I am tuning using lambda error and have my NGK WB set up using 10.42 and adder at .62. thanks
