Kelly,
All of the drawings on the Microtechefi.com site show four
injectors for the LTX8 units. In my emails with Paul this is the unit he
referenced. The Microtech manual does reference a Throttle Body setup that only
have two wires provided for installation. The normal product has four wires for
four injectors. It looks like Paul may have only been wired for two but the unit
does support four and injector staging.

Barry and Bobby,
I stand corrected !! Paul's "Microtech" was several years old........Does
anybody
know for sure if early versions had stageing feature ?? Dave Atkins
should
know......

Nah, his engine controller was the Microtech. I've been
looking at it too. It's Aussie, like the rest of them. Paul bought it from
Atkins, too.

Ed and All,
I may be wrong but do not believe that the
Engine Control System that Paul
had supported staged (four injectors) injection.......Again not certain
but I think
his ECS was a "Motec".........

John, I believe the TWM throttle body that Paul got
from Atkins which has injector positions comes with only two injector
positions. This throttle body was available from the distributor
(TWM) in either 2 or 4 injector model. I know from personal
experience that using the 4 injector TW (I had one initially installed) on
the 13B made a more difficult installation - because the two
injectors on the "inside" required you to position the TB a fair distance
from the engine block. So to avoid a lot of manifold work (extending
the TB further away from the block to give room for the two inside
injectors), the TB with only the two injector positions on the outside
were most favored for the aircraft installation. I believe that was
the only model sold by Atkins. I know of one other who also
flew with only two injectors, but there may be more.
Reduce fuel flow whether due to fuel selector
position or defective injector or combination during take off
would certainly be critical. As pointed out, when you lose one rotor
you lose more than 50% of your HP due to 1. Less rpm with only one
rotor ,2. drag of non-power producing rotor.

Does anyone know if and why Paul's engine was configured with one
injector per rotor?
