Steve,


Has the small opening between the trailing spark plug and the main chamber =
been modified?

Hi Guys

Today we got back into finding the terrible missing breakdown problem with =
the Renesis.
We had a list of faultfinding paths to follow but solved it with the first =
change.
Turned out to be the plugs. Swapped in the NGKBR10EIX (after grinding down =
a plug socket) and no more problem.

So she now does the following I think reasonably rich:
WOT Prop set fine               7467 RPM 29.8 Inches EGT=92s 1647&1497 23.7=
 GPH Fuel Pressure 43PSI Oil Pressure 68PSI
WOT Prop set course     5407 RPM 30.3 Inches EGT=92s 1579&1494 16.7 GPH Fue=
l Pressure 43PSI Oil Pressure 56PSI

The EM3 fuel flow is not calibrated yet so not sure how close the GPH likel=
y to be and therefore power levels.
I wonder what HP she is making.

Checked the dwell: See photo showing Rotor #1 T and L signals to D585 coils=
. Appears to be close to 4mSec=92s
Checked the signal from the CAS=92s: See photo of signals coming from the P=
rimary and Backup CAS (Primary is 4.8vPk-Pk and Backup 1.9vPk-Pk????)
I disconnected the Backup CAS and Engine still runs on B so??? (I=92m sure =
I set BUSENSOR in the code)
Sorry about the glare on the CRO screen.
