Hi I am a newbie to the ems thing anyways I was looking at my base tune fuel table. When I view it in the duty cycle mode I noticed some cells in the high RPM and Map reading is over 100. Can anyone explain to me why that is the case? I thought there is no value going over 100.

 

Did you set up your injectors correctly?

 

I talked to the guy who originally setup the tune. It is the correct injector setup apparently in the area on the table showing above 100% duty cycle is for areas I am not currently using, 7500-8000 above 30lbs of boost. I am only running 27 right now so he said he didn't pay much attention to those areas. I believe I was correct when I said there is no value going above 100%. If one has to go that high then the injectors is too small.

 

you need injectors. That number will go as high as it can. its just math based on your injector selection

 

The numbers on the fuel map are not injector duty. You need to log it.

 

Well, technically they are injector duty, but a more appropriate term would be target injector duty. There are other modifiers that will change the outcome, boost comp being the biggest.
