The MAP table has nothing to do with what the MAP sensor can handle. I had arbitrarily thought that 43"Hg was a reasonable target for max boost for this application so I spread the MAP table over that range. This only means that the last MAP table address is used at any MP above 42". The MAP sensor continues to increase the fuel delivery all the way to 60" Hg. So, the question is, do you find that you need a different mixture compensation factor between 42" and 45"? I haven't heard anyone say that but let me know if that is the case. I would suggest adjusting the MAP table at your highest intended operating MP and see if it is a problem.

All EC2/3s in the rectangular box (past 8 years or so) use 2 BAR MAP sensors which work up to 60" Hg MP.

Dave,

The top bin, += 127, on my EC-2 is 41.8 inches of manifold pressure.=A0 Does yours go higher?=A0

I just figured= that Tracy had something in mind when he set those limits.=A0 What does the EC-2 do when you go outside its limits?=A0 Does it keep everything the same as the last time it saw an instruction?

I have no inte= ntion of boosting my setup and I am roughly at sea level, (55 Ft ), so with ram air, I might be able to see 31 inches.=A0 The rest I will never use.
