We were all saddened when we heard the report of Ian's aircraft

mishap.

It

is a terrible loss for anyone that has spent years of effort in

creating

an

aircraft.
     I seem to recall that Ian was using a MicroTech ECU, as am I.

If

Ian

is still monitoring this list, I would love to hear anything at all

that

he

might be able to offer regarding how he initially leaned his engine

with

the

MicroTech, possibly with basic numbers and/or methods used. I still

have

my

head buried in the ECU manual....just hoping that Ian can give me

the

layman's leaning version, especially pertaining to initial setup.

Ian,

if

you are still online and may be able to get me started in the right
direction, please contact me off-line (since most people on the list
probably have Tracy's ECU) at  sqpilot@earthlink.net    My 13b

starts on

the

first or second revolution, and idles around 1400 rpm, but with an

EGT

of

700 degrees at 4000 rpm, I'm pretty sure I'm running rich, plus I

get

fuel

dripping out of my throttlebody upon shutdown, regardless if I shut

down

by

turning off the injectors, or turning off the fuel pump, or turning

off

the

ignition switch.  Thanks in advance for any helpful hints you may be

able to

share.  Paul Conner

Paul Connor,
Some of us who intend to use the Microtech also need to know any

possible

problems - keep the info public !

Hi Paul
I 'm also trying to sort a micro tech out. and also had a pipe blown of in
flight ,the landing had ripped of my undercarridge (this was last
Desember)but i 'm nearly flying again..
yesterday i had a look at www.microtechefi.com and i saw they had a nice
air/fuel ratio meter you can get from them , perhaps this thing will help
you to sort your leaning out problem . i've spoken to a guy here in S.A and
he will help me do the tuning (he is in racing) .My pipe had come of because
of i think a number of reasons.1 my timing was to much advanced(early) 2 the
clamps on the pipe not up to it , i'd changed them to Norma torro clamps 3 I
had a little T junction between the top of my res.to the top of the rad. to
the top of the engine for expelling air and this little shit had blocked ,
so i think i'd got a nice airpocket in the engine pressing the pipe of and 4
i had not beveld the alu pipe's so it was even more easy for the rubber pipe
to slid off.
any way ill send you the info for programming your ecu as soon as i had mine
tuned. the build in oxy .sens . in mine is way off to use is to lean the
engine out.
