Whats involved in swapping the regulator? Dropping the oil pan and a skinny wrench.
Thanks for the link. I guess I would need to fabricate an adapter to fit in the sparkplug hole.

Hi Bobby.
No idea on the plug change. Haven’t changed anything.
I had previously had one of the plugs fail as I tested it on top of the motor in diagnostic mode?
Whether it was part of a bad batch. I don’t know how plugs go bad.
I thought the gap was similar. Not sure what tracy has in the EC2 that may be attenuating its signal.
I haven’t checked the calibration of the oil sender, but was a little concerned about the pressure being a bit low.
Interesting your was also low. Whats involved in swapping the regulator?
Any theory as to how the plug change corrected the problem? Plug wire routing change?
CAS (Primary is 4.8vPk-Pk and Backup 1.9vPk-Pk????) - Back up CAS has a larger gap to the trigger wheel?
I wonder what HP she is making - Me too!
Oil Pressure 56PSI - I had similar oil pressure and swapped the stock 2004 regulator for the Racing Beat Street 90-95 PSI. I now see 88-92 psi at all but idle rpm. I have carburetor jets in the e-shaft oil ports.
Can you point me to the $22 pressure transducer you used to capture the pressure plots?
Bobby

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’s 1647&1497 23.7 GPH Fuel Pressure 43PSI Oil Pressure 68PSI
WOT Prop set course 5407 RPM 30.3 Inches EGT’s 1579&1494 16.7 GPH Fuel Pressure 43PSI Oil Pressure 56PSI
The EM3 fuel flow is not calibrated yet so not sure how close the GPH likely 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’s Checked the signal from the CAS’s: See photo of signals coming from the Primary and Backup I disconnected the Backup CAS and Engine still runs on B so??? (I’m sure I set BUSENSOR in the code) Sorry about the glare on the CRO screen.
