Hmmm, I have some mode confusion going on here. I have embedded
my comments.

When major changes like this are made you should start from scratch on
the MAP table, (reset mode 1), center Mode 6 with the program knob
at 12:00, and reset Mode 3. Then use a higher MP (24 - 26") to set
Mode 3 which is the current instructions in the latest manual.
I get that I am to reset the MAP table back
to original. My confusion is with Mode 6. I have the EC-2 and Mode
6 to set the large secondary mode is either on or off as I understand it.
I have set it to off to clear the large secondary mode. This is done with
the program knob set to 9:00. My instructions don’t address
setting the program knob to 12:00. Then I get that I am to recheck
the fuel injector flow rate with a higher MP of 24-26”.
Next do Mode 2 at lowest manifold pressure your engine runs at.
I don’t understand what I am doing
with Mode 2. One of the earlier versions of my instructions talks about
increasing the range of the manifold pressure that the EC-2 uses to make its
changes. This later one talks about idle jet adjustment. I think it
may have changed during one of my upgrades. This version is dated
7-Nov-07. Does this mode just affect the primaries and if so, when does
it stop? Thru the entire range, or just up to the stage point? Right
now, I have larger than expected primaries (330cc vs 195cc) and as a result, my
MAP table is set at -127 until staging. I am certain that this is too
low, because it is bottomed out and may actually need to go lower but can’t.
Next do Mode 6, checking the staging transition for
smoothness. Note! if staging is not smooth at the default setting
It means you haven't got Mode 6 right yet!
Again Mode 6 is just on or
off??! Are you thinking of a different mode here?
After these steps are done and working correctly, then and only then
should you start adjusting the MAP table using Mode 1 or Mode 9 (I like using 9
the best).
I recommend using the 4 yellow injectors for builders that have the 6
port engine but there is no reason the 2 red & 2 Blue setup from the 4 port
engine won't work if you follow the setup described above. It's so
smooth, I can't tell when my engine stages with this setup.
If your stumbles or otherwise misbehaves at staging, it means something is not
adjusted right. Do not accept anything less than smooth staging.
There was a hiccup at staging, but I think
it was related to the fact that the MAP table set at the bottom was not really
controlling properly just before staging. I expect that this will be
worked out when I get the MAP table adjusted.
If you think this is a complicated and difficult proceedure, you've
never had to rejet a carburetor.
Actually, Tracy, it seems to be pretty straightforward
and not too complicated after you read it a few times. It is hard for me
to get my head around how difficult it must have been for you to figure all
this out in the first place. When I set it up in autotune, it just went
to work smoothing out the engine. All I had to do was manage the throttle
to keep it on the pressure that it was tuning. I honestly think you are a
damn genius!

First, some
news..
I recently
redesigned my cooling system due to unable to run the engine for more than
about 20 min at high idle without it overheating. Now I have the good
problem. Granted it was cold..low 60s. But I was not able to get my
oil above about 145 and the water above 185! I ran it full bore
till I got tired of holding the brakes! I still need to do some work
balancing the air between the oil and water. And I didn’t have the
cowl on, so the problem is not completely solved, but I am on the right track!
Now the question.
I have the Renesis
that has the very small red primaries and the very large blue
secondaries. I recently changed them to all yellow. This removes
the need to balance the flow so much when it stages. The total output is
very similar between the two systems. Now I have a larger flow when on
the primaries and the secondaries kick in with a smaller change. I
removed the large secondary option using mode 6.
So I checked the
mixture at 22 inches manifold pressure and it seemed fine with mixture at
center setting so I deemed that I didn’t need to change the fuel flow
with mode 3. BUT when I started to let it auto tune, I noticed that it
was setting all the bins to -127 until after it staged, then it started to
build the graph that you normally see. It stages at 20 inches manifold
pressure. Is that the recommended pressure? I expected 15”??
So my question
is…Should I set the mode 3 at a lower setting? This will affect the
entire range so I am concerned that I will not have enough fuel at WOT if I do
that. Should I make an adjustment using Mode 2? I don’t
really understand what dynamic range is?? What are your thoughts?
Thanks,
