Leak down test
Before anyone does a reflash, you should first do a cylinder leak down test.
Motor Performance before the reflash...... And performance results after reflash are worthless leak down numbers.
The big problem with reflashes is...... ( we do NOT know the leak down % on the sled Polaris is using for the mapping ).
Are they using a brand new motor ? With 3-1/2% leak down?
Are they using a 500 mile motor ? With 1-1/2% leak down that had a great cylinder finish and rings sealed up nice ?
Are they using a 500 mile motor ? With 7% leak down that has rings that are on their way out the door...... ( basicly junk )
You see if we knew everyone's numbers...... Then we could see who's sleds the reflash works on and if there is a correlation to the leak down numbers.
And there will be........
If you build a map on a sub-par motor the map is basicly worthless to everyone except another guy with the same sub-par motor with the exact same leak down.
If you build a map on a broke in motor with 1-1/2% leak down...... The Map will be awesome for everyone with a good solid top-end with good % numbers.
As I have said...... All the different results are worthless to the masses without leak down numbers

You have been busy. Maybe it’s copy and paste?
