Post Rambler (AMC, Nash) 195.6 OHV inline six maps 
Engine Mfg: Rambler (AMC)
Engine Code: na
Cylinders: 6
Displacement (cc): 195.6 cu in
Rev Limit: na
TPS or MAP: MAP
Boosted or Normally Aspirated: NA
If Boosted- max Pressure (KPa):
Modifications: 9:1 forged pistons, valve head port work, Weber 38/38, reground cam (increase LSA)
Chassis: 1961 Rambler American roadster
Notes:

this is the "old" six, not the "new" one intro'd in 64, aka the 232, 258. this is the old Nash motor that AMC stuck a new head on in '58 to tide them over until the new six. 3.125" bore x 4.25" stroke, very undersquare. practical RPM limit is 4500 rpm, but usable torque at 1200. the factory distributor provided 11 degrees mechancal 11 degrees vacuum advance for 22 total over the 5 BTDC static. as you can see the EDIS-6 is a huge improvement.

this map has more spark, even though compression is higher, probably due to improved cylinder filling and richer mixture (installed wideband AFR and runs 14:1 now).

this first of two maps(10 aug 2017) is on the current "high performance" (it's all relative, yo) build with Weber 38/38, T5 transmission and 3.42:1 axle and 24" tires. these maps were made cell by cell on the road, but 3800 up values are extrapolated.

the bins have been adjusted to better map the engine's usable range.

this map is "before" the most recent build, the engine more or less in factory trim other than a Weber 32/36 DGEV, a T14 transmission and 2.73:1 axle, 24" tires. these maps were made cell by cell on the road, but 3800 up values are extrapolated.
