Hi Rich. Built a bracket to mount it 90 deg from Renesis main CAS mount. Sorry I don’t have a photo. Tracy’s code incorporates it in the EC2. I mean there is at least a declaration in the code “BUSENSOR", but I haven’t checked the code to see if it was functional, just thought it was. I suppose I have always wondered about failure modes of the CAS. Of all failure modes I think the CAS is very low risk. I thought the weak link was the vulnerability of the wire feed itself to a broken belt etc. So Ive wondered about the point of a backup. Maybe just armour plate the signal from the one CAS. We had a Glasair III go down here in Perth - full electronic ignition on Lyc that was taken out by a belt breaking. He lost his engine, managed to put it down on a school oval but got terribly burnt.

How's did you mount the aux CAS Thanks Rich Sent from my iPhone On Aug 12, 2016, at 8:34 AM, Bobby J.

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?

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. -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
