Bananawasp Posted January 4, 2020 Report Share Posted January 4, 2020 On idle what should I expect my injector duty cycle to be. I'm trying to work out my resolutions in the fuel table. I have my injector master fuel at 6ms with plus 20% trim. That's giving me around 38% in my fuel table on idle but my injector duty cycle seems really low at 1.6% maybe that's fine I'm relatively new to this just seems low to me. I'm running 550cc injectors on my R53 mini cooper s. Thanks Quote Link to comment Share on other sites More sharing options...
neil brown Posted January 4, 2020 Report Share Posted January 4, 2020 Running 565cc on Impreza and see approx 1.3% duty at idle of 900rpm Quote Link to comment Share on other sites More sharing options...
Bananawasp Posted January 4, 2020 Author Report Share Posted January 4, 2020 Excellent seems to be pretty similar then. Thanks for your response. Quote Link to comment Share on other sites More sharing options...
cj Posted January 5, 2020 Report Share Posted January 5, 2020 duty cycle at idle is pretty misleading because it has so much time between injection events, that the "% on time" is always going to be low. normally i'd look more at "effective pulse width (ms)" as a measure of "normal". On a 1.6 with 550cc injectors its probably in the 0.7-0.8ms range. Quote Link to comment Share on other sites More sharing options...
