trying to figure out how to make smaller percentage fuel changes in aem series 1. Mines set to maybe a 5% increase or decrease when pressing + - in the map. Any help would be greatly appreciated

 

What is your microsec/bit?

 

How do you check that?

 

It is in the advanced fuel section.


Microsec/bit defines the value of 1 for the fuel map.Here is a guide on how to boost compensate the fuel map to gain resolution.

Alright my microbit was at 80. I lowered it to 40, will I have to add fuel everywhere to compensate for changing it? Thanks

 

IF you read that boost comp thread it should detail how to change the microbit/sec without having to change the fuel map.


If it doesn't it's simple. Copy/paste your entire fuel map into a spread sheet BEFORE you change the microbit/sec. Change it to what you need, then paste your map back and there you go.

Make sure you are viewing your fuel map in Duty Cycle before the copy and paste function. Also you will have to adjust your start fueling stuff. But the main fuel map is the biggest part. Also remember to save a version of your map before, and then make the changes so you have something you can revert to.
