Cool 550cc and 1600cc MSQ

Im basically using a 4x550cc fuel map only changing the fuel requirement to 3 right now to get the car started. 2x550cc and 2x1600cc

If you have 550 primaries and a 550 map, Req Fuel should not change, only the staged injector settings.

I'm referring to MS2/E 1.0.2 and 2.0 which asks for primary, and secondary injector size. I'm not familiar with the firmware you're running.

ok I got the car running with staged settings. Although the req_fuel did not change in the constants I did have to change the map a lot, using a transformation using a constant of 6 and then calculating the table with the change.

the 1600cc are sleeping for now until I tune with a wideband, I used 2 pulse width gauges in megatune which indicate when each bank fires and so far so good, only the 550cc fire.

here is a youtube video of the car idling, timing was advanced like 5 degrees at the time of the video, still tuning timing too.
