Believe ive asked this question before but never got a direct answer,when tuning VE tables and my scanware shows BLM value of 118 at 3200 rpm 55 kpa - since the KPA values jump by 10's do i make the move at 50 or 60 KPA? or split diff?
To date ive been changing the one that looks out of place and its been working but I hate guessing.....

Thanks for any help.

 

You try for 128s.
There is nothing wrong about 118, if the car is running right.

 

I generally look at the rest of the data and find points closer to either coordinate...like 49 or 41. Right on the median at 45 could mean either or both 40 and 50 are off to varying degrees.

 

I would look at the scan and see if the BLMs go lower or higher on either end. So if the BLMs are closer to 128 at the 40kPa level but start to drop the closer you get to 50kPa, then I adjust the 50kPa.

 

Well i would not want my wot f/a ratio to be decided off of that.

Thanks guys for (answering) my question.
Ill try to use that info.
