[urq] Resolved! EFI + MAC-14 maxing ataround 5k RPM

[Ben Swann]

I don't know what to say about the plug and compression test - I knew I had some rich
spots and under normal driving however the carbon would burn off as things are lean on
cruise.  I did have some obvious things to address and some things I thought were off,
leading a bit astray on diagnosis.  Also, it takes awhile to do certain things - it took
me about a week to get the fuel pump issue straight and one does not always work on the
same problem at a straight shot, in fact I was sidetracked for a few weeks while dealing
with the car from Canada.  So yes, I probably should have checked them earlier, but it
is always things are somewhat obvious after the fact.

The engine still needs tuning, but I'm very pleased right now at how it is operating - a
little surging on cruise=too lean and probably still too rich under high load and RPM.
These I'll work out.

Megasquirt has a lot of parameters to deal with, and right now even with being set for
the wrong injector, other factors compensate making it run right.  I just need to get
over the learning curve on it.

Great you sussed it, and now you have well deserved rocket ship that you 
wanted. In the end it was very simple, but wouldn't an early check of 
plugs lead you to same conclusion?
Q: Could the injector timing be altered om MS, or just the amount?
