Hey,

I wanted to try and figure out the BPW between $8d and $58.

Let me explain:

First, I zero'd out the VE adder table in $58.
Next, I imported all my table data from $8d into $58.
Then, I imported all the spark advance data as well.
Double checked all constants, made sure they are the same.

The issue is the base pulse. On $8d you set cyl size, and injector constant.

On $58 you just set the BPW. Basicly, I want my BPW in the $58 bin to match, and I want to see the exact same injector PW's at each map vs rpm cell.

How do I do it?

Lemme just add something. I *know* the suposed correct match to get the bpc in $58..

BPC = 730.75 * (vol / rate)

With my 36# injectors, the BPC should be 116.79

I don't trust this produces the same PW's as entering 36 in $8d.

On an ecm bench.
I never got the two to jiv, with transposing numbers.

 

Wow Grumpy, that was quick.

So what would you do, pick a rpm vs map point, and record the pw, then do the same thing with the other code. And adjust BPC until you get the same number?

Is the VE math dead on? I.e, if one cell produces the same PW once you got the BPC figured out, will the rest or are the VE numbers completly calculated differently?
