Boost it map
hey
Here is a map I got from Niel as a start. I had to lean it a little .. may also increase theresld a 1-2 number closer to 0
"In order to run this map, the boost feed to the XIC must come from the airbox or charge side only. By doing this, it will pretty much eliminate a lean condition when dumping the throttle.
If there is no nipple that can be used in the airbox, then “T”in to the line between the turbo compressor housing and the boost controller.
The “min rpm”setting must be changed in the hidden settings. To access the hidden settings, hold the left arrow key down on the xic while powering it up or starting the sled then continue to hold it until the xic finishes the startup sequence. It will stop on a screen that has a lock code. From there use the right arrow key and toggle to “min rpm”. For the 800 set min rpm to 50 and for the 1000 set min rpm to 56. This will limit the fuel start to 4500 rpm on the 800 and 4200 rpm on the 1000.
Continue to toggle to the right and confirm that the tachpulse setting on the xic is set at the number 2. There may have been some proclimb xics gone out at tachpulse 3.
Now continue to toggle to the right until the threshold screen. Set this number in the negative 8 value to start. I will have a guide for where this number should be for a set elevation range. Now set main fuel at 50 for the 800s and 55 for the 1000.
Now toggle right arrow to the rpm trim screens. They start at 3000 rpm and go up every 250 rpm.
1000 settings
3000-3750 -20
4000-5000 – 25
5250-5750 – 20
6000 – 15
6250 – 10
6500 – 5
6750 0
7000 +2
7250 + 4
7500-9000 + 8
At this point, I would like to use the threshold number as an altitude compensation number.
Below is a guide of where the threshold should be set vs elevation
0-2500 ft – 6 value
2500 4000 ft -8 value
4-5500 ft – 9 value
5500-7000 ft – 10 value
7000-9500 ft – 11 value.
All above are threshold in the negative settings.
The threshold should only have to be touched 2- 4 times a day. Maybe once or twice going up in elevation and once or twice coming down.
This is a very easy adjustment that takes a few seconds and makes a huge difference on how the sled will perform.
If fueling needs to be adjusted for the top end fueling then we suggest that you use the top end trim numbers and set them up or down a couple points at a time to get your desired afr reading at wide open throttle."
