Still plodding along down here in = Houston trying to=20 develop my 13b. It is starting up with some difficulty when I = first get to=20 the hangar and running more smoothly as I ease my way through the auto = program=20 routines. I spent Tuesday and Wednesday (my weekend) doing a lot = of "I=20 gotta get back to that" tasks and made some wire connections permanent, = secured=20 my panel <g>(...even if fiberglass, it is a pain to work with = a=20 floppy panel), replaced some wires (my oil temp wire was toast....thus = causing=20 44 degrees to read for oil temp on the EM with no change. It = is=20 reading true now that that one pesky little wire has been replaced and=20 rerun.

I am still having problems with = Controller=20 "B". When I switch from A to B, the engine seems to want to stall, = since=20 the engine will not restart for a few hours (so far) after a run I flip = back to=20 A before this happens. At higher RPM I can make the switch between = controllers and it does not stall, but runs significantly rougher. = Could=20 this just be due to the Auto Program refinements not yet being = transferred to=20 "B"?

After my various efforts of the last = few days I=20 decided to run some base diagnostics on the machine since I had made so = many=20 little changes/improvements(?) over the last few days. Meaning I = did the=20 diagnostic modes on the coils and the injectors. When I first = arrived I=20 started the engine and started tweaking and testing. One of the = test I=20 performed was to disable the primaries and secondary's in = succession. When=20 I disable the secondary's I did not notice any change in the way the = engine=20 sounded, but when I disable the primaries the engine would start to shut = down...so I quickly flipped the switch back up to the on position to = avoid the=20 shut down. I did this a few more times over the next couple of = minutes=20 with the same results. Hmmmmm. Anyway, I decided to put this = to the=20 side for a moment and I pushed the throttle to WOT. WOW, the temps = rose=20 pretty darn quickly at full throttle.....the temps were staying around = 150 ish=20 at idle and the lower RPM, but really soared at full tilt. The = displayed=20 RPM on the EM are still jumping all over the place since I have not = addressed=20 this issue as of yet....flickers from 2000, to 4800, to 1200 back to = 2000, to=20 4900 ish with a few numbers in what I think in the correct range = predominating=20 the various numbers. I was a bit disappointed that the highest = number I=20 saw with WOT was only about 4999 ish. Seems low. Is the fact = the=20 engine only has a few hours on it and or is still not tweaked a reason = for this,=20 or is this expected sitting half in, half out of the hangar....yeah, the = prop=20 bit is outside in the sunshine <g>?

Finally, for tonight anyway, back to = the=20 injectors. After my data gathering run was complete I went to the=20 diagnostic mode on the ECU. When I tested the injectors as if they = were=20 firing at 3000 rpm I disable the primaries and could clearly hear the=20 secondary's clicking away from inside the cabin. When I disabled = the=20 secondary's I couldn't hear anything until I stuck my head outside the=20 cabin. When I went around to the engine I could clearly hear the = primaries=20 clicking away, but at a MUCH reduced volume of the secondary's. = Does this=20 matter. Do the two different types have this significant of a = sound=20 difference? Could this explain the about mentioned shutting down = with the=20 injectors were turned off during the engine run?

As always guys, thanks for your kind=20 considerations. As I have mentioned before all commentary is=20 welcome. I am not insulted by the most basic suggestions and=20 observations. I am way to close to it at times to notice the = obvious but=20 open enough to learn what I didn't even know I didn't know.

Eventually I may get over the sensation = that every=20 time I run the thing, let alone run it at high RPM, that I am doing some = great=20 harm as opposed to just be pleased and amazed that this engine Dave = Staten and I=20 built actually runs at all.

Like my messy and cluttered = hangar....these messy=20 and cluttered emails are signs of PROGRESS (yeah, that's = it)

All the best,

Chris
