Marc, Simple digital systems in Canada markets a system with

secondary

injectors for boosted

engines. They have a good rep wiiith everyone I've talked to that

uses

their stuff. Point of fact

in Livermore there is a 1/2 scale p-38 using two suzuki swift

engines,

(normally aspirated), they

could never get it to run correctly on the stock injection but the

SD

system worked perfectly on

both engines. Why the stocker didn't work is a mystery to me.

Probably

fuel delivery related but

the Simple Digital system worked great. They also have a rotary

specific

system. They don't offer

a 3 rotor version so far. Tracy at rws can probably set up a system

for

the secondary injectors as

well. Bill Jepson

Bill,
I have Tracy's fi/ign sytems set up for turbocharging. However, no one
to my knowledge (incl tracy) has made an integrated turbocharger
electronic control system suitable for aircraft uses (car ones are
avail, but the control logic might not work for our uses, I just don't
know). This system would be electronically integrated with the fi/ign
computer, and have provisions for either turbo-normalizing to a set
point or selective boost over your pressure altitude.....and it would
stipulate a blow off valve as part of the installation for safety's
sake!
