  • Suitable for use with ethanol, methanol as well as most oil based fuels
  • Modern design offering extremely good idle control
  • Full injector deadtime/battery compensation information is supplied with each set of injectors

Lower adaptor is an option.

4.0 bar = 58 PSI

What is your maximum injector duty cycle?
%

ℹ We recommend a maximum below 80% to leave headroom for tuning. Different applications might want to see a lower duty cycle (ie 65%). This is best discussed with your engine builder and/or tuner.

What is your target lambda?
λ

ℹ Lower lambda = richer mixture = more fuel required. Default is set based on your fuel & induction selection. Adjust if you know your target.
