Now that I hopefully have my strakes = mostly=20 repaired I am able to focus on the engine again. So, in that vain = I have=20 been able to run it the last few days trying to get it tuned properly = and=20 hopefully reliably. We have had some cool weather.....heck, for = Houston it=20 has been downright cold dipping into the mid 40's, thus allowing me to = run the=20 engine at higher power settings for a bit longer. Also, based on=20 discussions here last week I am modifying my cooling system a bit...I = have had=20 my small hose opening on my rear iron plugged up to this time, but will = modify=20 when my new aluminum expansion tank arrives. Funny, after = following rotary=20 stuff for years I missed this apparent cooling convention.

One issue I am having is that = regardless of how=20 high I push my rpm's it appears that I am only running on the primary=20 injectors. The EM2 continues to display the asterisk even at = WOT. =20 Also, when I shut down the primaries at high rpm's (well over the = staging=20 point....3000 ish?) the engine dies...actually, it dies whenever I shut = the=20 primaries off but I would expect that at lower rpm's and idle (kinda = rough idle=20 around 1500 rpm, but also kinda expected with a medium street = port). =20 So, to confuse me more in my initial diagnostic I shut off the engine, = kill the=20 fuel pumps and place the EC2 in Mode 1, injector diagnostic. All = four=20 injectors fire away....I shut off the primaries and the secondary's = chirp=20 away. I shut off the secondary's and the primaries still clatter = on. =20 This is what I expected, it just is not doing the same thing when the = engine is=20 actually running. Thoughts?

Also, a second issue, one I was just = starting to=20 try to solve when my strakes became the priority, is that as I approach = 6000 rpm=20 on my EM2 display the indicated rpm starts jumping all over the = place....1200,=20 3543, 3333, 2650, 6314.......randomly. It is doing this even = though the=20 engine is still developing more power, obviously over 6000 rpm...as you = can tell=20 by the sound and the increased power. As I throttle back to = about=20 5900 the indicator starts displaying as expected again. Additional=20 thoughts?

As always thanks for your consideration = and=20 insights.

Finally, it is kinda kewl to have the = "airport=20 types" stop by to comment on the noise.....music...noise....music....all = in the=20 ear of the listener <g>. Today Gary Hunter, a name well = known to=20 most fast glass guys (he is also the crew chief for Bruce Bohanon's = Flying=20 Tiger) stopped by and said it sounded "strong". Wahoo. Gotta = take=20 the small victories.

Thanks again.
