Can not find 747 AFCB bin. - or what is close? And also a question attached
Well I am tuning a 747 for a friend and its a first for me as I have played much with the 165 and 730's but never with a 747.
I decided to play around with bin stacker (which I have never used) always use offset on PP.
Well anyway i totally fubared the AFCB bin. Can anyone tell me what bin to use in place of (350 truck)or anyone have an AFCB? I already gave the guy his stock prom back after I loaded it.
Can not seem to find it searching.
My other question:
The engine is basically stock but stroked to 383 and in a flatbed.. I see the 747 does not have the simple cylinder volume constant. So should I just scale the VE first, or is there something with the BPW?.. I seen some sort of equation of what the BPW is derived from on 747 but did not really understand.

Val = 1461.5 * (VOL/RATE)
VOL = Vol of 1 Cylinder in liters, (0.7125l)
RATE = Injector flow in gms/sec
5.7l = 7.71 gms/sec (61.2#/HR)
(VOL/RATE) = 0.0924 l/gm/sec
40 #/hr = 5.0399152222 gms/sec
55 #/hr = 6.92988343056 gms/sec
61.2 #/hr = 7.71107029 gms/sec
65 #/hr = 8.18986223611 gms/sec
80 #/hr = 10.0798304444 gms/sec

I take this equation: Val = 1461.5 * (VOL/RATE) but I modify it. It never comes out right if you plug everything in. I'll use ASDU as an example. I KNOW ASDU BPW is 135 and I know the fuel injector rating is 55pph. If you use this equation for ASDU the says the BPW should be 150 but it's not in the bin.
So take the bin you're starting with. ASDU has a BPW of 135. I take 135=x * (.7125 / 6.929). X = 1312.9, which is the constant for ASDU that I will use.
BUT you're running a 383 that has a cyl volume of .7845 L. So if you start with ASDU AND 55 pph injectors...BPW = 1312.9 * (.7845 / 6.929).
I've used this method before and nailed it every time. I think it's because the proper fueling also depends in the VE#1 and VE#2 tables.

Well I just figured them out assuming 61# injectors (stock on 350?) and BPW came out to 147 for the 383 using the first equation you showed me .... Also when firured out for stock it did come out to 135 as supposed to.
But guess what, If you just take 135 stock asdu BPW fon 350 and just devide that by 350 then multiply by 383 it also gives you 147.. And seems alot more simple.
I loaded the asdu BIN, I assume this is a 5.7/auto bin? It did have BPW of 135 and converter lock/unlock settings accurate.
Thanks for your help, Now just waiting on my G2 from craig.
P.S. Is my conversion right?
