you just clear out the cloudsQuote:
Ideally you want it just above what PSI you are reading and may read in the future in better DA. This will make the SD equations fit the best.
Leaving the MAP per air mass(M) and MAP at zero air mass(b) tables stock he would need to use 30-31 PSI to see 1.5-1.6 engine load. Mx+b=y. x is air mass in LBs, derived from MAF lb/min and y is calculated MAP. Start at the calculated MAP MAX in inHg and work backwards you will get air mass values. divide those by the engine displacement value 0.00183 and you will get the maximum load values.
example at 4286RPm
At 31 psi
63inHg=2.44inHg+x(19,865inHg/Lbm)
60.56inHg=x(19,865inHg/Lbm)
0.00305Lbm= x
0.00305/0.00183= 1.67 engine load.
If it was lower:
at 23 psi
47inHg=2.44inHg+x(19,865inHg/Lbm)
44.56inHg= x(19,865inhg/Lbm)
0.0022Lbm=x
0.0022/0.00183= 1.23 engine load
