BPW and Injector math

[EagleMark]

I moved these fuel pressure posts here Greg...

There's some polishing to do, thanks for the mask names on sheets. It's a lot of info, but all you have to fill in is White Boxs first set. Last st are optional calculations.

Were you happening to run up to 49% IDC on the old one?

I would have to fire up the laptop, and check a log, but I am pretty sure I was hitting around 38% (would really be around 80%) and IPW would not go higher than 4.2ms, which is fine at 4K rpm but not at 6K.

I am really super lost in this thread and its all 99% over my head. But did I read something right, saying that the injector duty cycle % display in the 0D ADX is wrong?

So far everything I've checked is only half... try this!

Tried that ADX and if it is correct, then I am going well over 100% DC when in PE and hammering on it. I saw the DC go up to 119.02% on a recored log when I was hammering on it. TPS 73%, MAP 90, 4000 RPM, and in PE. WB AFR was still at 12.6, so it wasnt going lean, but I cant speak for weather the injectors were going static.

Are you 100% sure it is displaying the correct DC %?

Exact same time data sample on the normal adx was 59.51% DC

Sorry, for got you were MPFI, change the 4 to a 2 in conversion.

TBI IDC (%) = [4 * IPW (ms) * RPM]/1200
MPFI IDC (%) = [2 * IPW (ms) * RPM]/1200

Ok, did that and it changed back to what it was before in the old ADX. Same time stamp data sample listed above, its 59.51%. So I'm guessing I'm good?
