Hi,
I'm gonna be shooting another extra 50 dry on top of a 120 dry shot.

How much % increase in fuel do you think I would require in PE (power enrichment)

5%
10%
15%

To keep me safe for a trial run. I just don't want to be too lean or too rich.

Thanks

 

Here's the basics.
14.7 / PE multiplier = commanded a/f at WOT

So, if ya want a set a/f just add in the correct PE multiplier. A little rich is not a bad idea if you don't have a wide band, however, you can use the NB for a general idea.
Here are some of the multipliers:
1.300 = 11.31:1 a/f ratio
1.275 = 11.53:1
1.245 = 11.80:1
1.205 = 12.20:1
1.170 = 12.56:1
1.150 = 12.78:1
1.130 = 13.00:1
So you can figure your multiplier out to what ever ratio you want. Remember to also set your PE RPM activation point to below your low rpm setting on your WS, this will help with lean spikes.

I wouldn't waste the time on the 50 shot, not even for "testing" purposes. Throw the 100 in there, and check it out. Leave PE about set to about 12.5:1 and have fun.

 

10%...

 

Holy Cowbells....haven't seen you out in a while. Of course, I've been out of the net myself with Flight School.

 

Is is wanting to add 50 MORE to his 120 shot he is already running.

Thanks Robert, I understand

the PE rpm activation is 2800, my nitrous activates at 3200 and I do have a wideband. I just did not want to be lean and fry something.
