Type 1 board with S12_CA18ET_33F01 ROM loaded. Car is now fitted with S14 MAF and 370cc injectors.
When I go to resize injectors, old = 270cc, new = 370cc the car won't run?
Confirmed injector sizes etc and found that if I enter old 370cc and new = 270cc the K value is correct and the car will run. Think I'm getting knock now but will look into that when I get time. Just thought I'd post this in case it helps anyone else? Is it a bug or have I misunderstood?

Did you also change your MAF size?

Try increasing K constant until engine runs again. There is no bug in the injector resize in the software
