I upgraded to RC440's and used the emanage Injector Change factor to compensate for the larger flow. I do not think I have the correct values entered as things are a bit off.

Right now, I have 370cc entered as my "before" injectors. The idle is 10:1 and takes 30+seconds to return to 14.7-15.1 range. The odd thing is the car leans out well before boost under partial throttle. I am adding fuel in various cells from 40kpa on up to keep it going.

If I switch to 360cc my idle is perfect but partial throttle acceleration goes beyond 18:1 a/f and then it chokes out.

Any idea of why this is happening. Is the Injector Change option just off or do I have my values crazy?

Finally, is it possible to go back to my stock injectors and still retain the FPR with the emanage or is this not possible due to the lower pressure?

 

The Injector correction factor on the Blue e-manage has been hit and miss at best. It's meant to be used to build a rough and usually very rich fuel map to allow the car to run "good enough" to start tuning.

With the Blue e-manage, you use the airflow adjustment map to remove fuel to compensate for the big injectors. You then use the additional injection map to add fuel to keep the A/F in range.

I haven't looked into the Ultimate e-manage to know what has changed.

 

The ultimate can remove fuel directly without fooling the computer into thinking there is less air. I just find it wierd that I am so rich at idle but so lean as the rpm's climb while I'm still in vacuum. I'm using the correction factor and then having to add fuel throughout the first 4 rows. I'm thinking it might be best to just not use the correction factors and manually remove fuel throughout the map. Any downside?

 

The correction factor gets you in the ballpark, you've got to put the all the players in the correct position.
