BTW, after too many years of being to busy to work on my Renesis /
Glass Goose project, it looks like I may be slowing down enough to
restart. Luckily I have been flying (Skymaster) in the interim.
Lots of catching up to do!
You may remember that I have a Bruce Turrentine Renesis 6-port and
Tracy's EC-2 and redrive. I see that the EC-2 only supports 4
injectors, while I have 6 altogether. Do you know if anyone with a
similar configuration simply did not use (blocked off) the two engine
block injector ports (red injectors)? Or it necessary to use all 6
injectors?
You may also recall that I built a small intake with throttle body
based on the original intake manifold, so I don't have the long
runners. I realize this will produce less HP, but I only need about
180-190 -- which might make the center injectors less important? ( I
can also re-do the intake relatively easily if needed.)
Thanks,
Scott Gettings
Perhaps some one will read this and respond. In theory you do not
need them with Tracy's EFI. However tuning with Tracy's is always a
pain in the butt :-)
It is pretty easy to do your own EFI with a Maximite. The easiest
hardware control computer in the world to program.
Not a very steep learning curve. I can help with out a lot of time or
trouble and you would be doing all 1000 people on here a big favour
as it would be open source. You could use all six injectors for
smother running.

I will definitely have a lot of catching up to do! So the Maximite
will handle both the EFI and ignition coils? The programming is
beyond me, but my brother might also help. I assume I could test
the Maximite on my RX-8?
I will look for a source unless you have one handy.

Version 2 is now out with higher performance.
The web site does not do it justice. Some times I think CG doesn’t
understand just exactly what it does. It is like a complete DOS
computer running QB with a solid state 64Gig hard disk.
"The CGMMSTICK and CGCOLORMAX have the Maximite BASIC (MMBasic)
interpreter programmed into the PIC32 microcontroller. "
Not only is the BASIC interpreter programmed into the PIC32
microcontroller the programming editor and a disk operating system is
also built in to the microcontroller.
The Maxm+doc jpg shows a Maximite set up next to another computer
running the PIC BASIC pdf doc for rapid access to any BASIC command
info. This is a major breakthrough in the ease of programming micro
controllers.
For $57 it is an extreme bargain.
BTW
Harbor Freight sells a low cost one cylinder piston engine. Perfect
for getting your feet wet in EFI.
Once you get that to work expanding the number of injectors is a
piece of cake.

To get on step in the water quicker 250HP might be a good idea.
The p-port conversion is inexpensive and makes the manifold easier.
Put two injectors in each intake pipe. For redundancy, set it up to
run one on each with one Maximite and the other two with another.
You could set up the ignition the same way. One for leading and the
other for trailing. Or one to run 1 leading and 2 trailing and the other
for 1 trailing and 2 leading. Better insurance on keeping the power up.
