I=E2=80=99m using the standard 4 = port injectors.
I could check with a cro if they = are maxed out.

Hi Steve

What size are your = injectors and fuel pressure setting? I had those symtoms when using too = small injectors, changed to 60lb deka's, no probs since.

 I used a sensor on = the prop for my efis rpm.

Hi Guys

Did the first high power testing of our setup yesterday.
Renesis 4 port EC2 RD1-C electric pitch adjustable prop on Glasair Super = II RG
Engine sounded good.
On a fine pitch setting she spun out to 7200rpm.
On a course pitch she gets just over 6000rpm.
Our intake manifold is a modified original Renesis.
The length is shortened, Secondaries Valve removed, but kept the = Variable Intake Valve.
Primary and secondary runners are different lengths now unlike the = original setup unfortunately.
At 6000-7000rpm opening the valve provides another 200rpm so dynamic = charging appears to be
working despite the primaries being shorter than the secondaries.

Confession time!
Experienced a small fire from the exhaust where I had some insulation = rap.
Turned out I had a very small oil leak from the sump had dropped a small = amount of Mobile#1 on the exhaust wrap which then ignited.
Had extinguishers at the ready so no damage done. I subsequently found = quite a few of the sump bolts were loose (poor on my part).
= Hopefully no more leaking oil. Thankful to find the problem on the = ground while testing!

A few issues came up and I would appreciate your brains and wisdom:
1. RPM above 6000 the Dynon Skyview and the EM3 stop reading correctly - = both take their tach input from Injector #1.
   Now if it was just the Skyview units I=E2=80=99d look at = the signal level. But the EM3 is also playing up and has me stuck = pondering at present.
   It seemed to go intermittent but and perhaps come good = above 7000rpm?

2. On the course pitch, as soon as the rpm gets to 6000 and I continue = to open the throttle, it goes from smooth to massive missing and rpm = drop.
   Any thoughts here?
   Related to point #1 above? Don=E2=80=99t think so as on = fine pitch rpm doesn=E2=80=99t read properly but spins faster with no = missing.
   Don=E2=80=99t recall mixture when this happened.
   I think its related to load?
   What could cause this?
   a. Fueling - I tried adjusting mixture but with no success. = Thinking I need to experiment more with mixture when this massive = missing occurs.

 b. Spark? Coils are D585=E2=80=99s
   c. Manifold pressure fluctuations feeding back into EC2 = creating fueling issues?

Thanks in advance for your thinking on my problems.
