What did irregular map signals = look like in terms of engine running on your engine?
What engine/setup do you have?

Hi Steve
Just my 2 cents, I had irregular map signals so I installed a = mig welding tip for .6 wire and that sorted it out simply for = me.

Hi Guys

We did further testing of the Renesis today. Would really appreciate = your heads on this.
Last series of tests we had this major missing and noise which I think = is fuel exploding in the exhaust.
This happens at various RPM=E2=80=99s based on load from the adjustable = prop.
With fine pitch it would spin out to just over 7000rpm before striking = this mayhem.
With medium pitch it would get to 6000rpm before the same symptoms.
=46rom memory these were both at about 22-23 inches of Hg.
My Wideband O2 is malfunctioning at present.
The narrowband response time appears to slow to discover what the = mixture is doing during the episodes.

Also still having trouble with the EM3. Sometimes display reads what = appears to be an error message and at other times stops reading RPM.
The Skyview Engine monitor has the same issue at the same RPM so appears = directly related.
I changed the input on the Skyview to the Standard RPM input as I = incorrectly fed the injector pulse to the lower voltage input, but this = made no difference.

I had wondered if the secondary injectors weren=E2=80=99t getting power = and as a consequence when it staged to all 4 injectors the trouble = began.
Using the EM3 display (staging asterisk) and switching power off to the = secondaries I was able to ascertain that the secondaries appear to be = functioning fine.
I did notice that the point of staging appears to be not solid.
This takes me back to Ed=E2=80=99s comments re damping the manifold = signal to the EC2.
Sorry Ed, you might have had it right last week. I thought because it = was running so smoothly up to 23 inches that it wasn=E2=80=99t a signal = issue.
Maybe the wavelength/timing of those pulses at ~6000rpm matches the = manifold signal tap position!

Ed, you mentioned either small orifice or accumulator. I estimate the = volume of the signal line to be approx 18 cubic centimetres.
My gut was that the accumulator required to damp the signal would need = to be an order of magnitude larger. (total guess)
So maybe 180 cc=E2=80=99s but thats half a Coke can! Seem=E2=80=99s way = to big.
Ed, did I understand you right that a small fuel filter can do the = trick? I thought they would only be about 10 cc=E2=80=99s in volume.
I suppose if the pulses are very narrow/short maybe thats all to takes = to damp out the pulses.

Can I ask the group please. Who had trouble with manifold signal and = what was the solution that worked best.
Paul Lamar advocates tapping the signal from the oil injection ports. = Has/is anyone using this solution?

Thanks very much everyone.
