Engine is one I am building from drawing board up for an aircraft that I am also building, hence the low rpm as it is direct drive.
- Static ground revs no more than 2700 other wise the propeller tips will break the sound barrier (inefficient)
- guessing: 3000 RPM (=50 rev / sec) = 330 m/sec, circumference = 6.6m. Is the propeller dia ~ 2meter ?
- we put as much pitch on prop as to limit revs
- also engine internals would not take high rpm (the internal forces go up by the square of the revs])
- legs out of bed in the sky causes one to sweat a bit , thats why we use the fan to keep us cool

Injectors are out of a Nissan 280z are 2.6 ohms [ barbed tail, will consider changing ] and best idea of cc rate is 270.
- we do not recommend low-Z injectors even on ground.
Is there a manual directly relating to VEMs tune 0.10.14 I am finding it impossible to go forward without better information. Basicly the Members page have answers but generally dont say how they got them it is also a pain to wade through such a lot of data and not really gaining much
It now seems that the MAP guage on main screen is directly controlled by the movement of the throttle , The d TPS/dt digits below this heading[reading at255 at 100% throttle] are the same as in the MAP gauge [main screen] these change as the throttle is moved is moved and read the same. So far all that is connected are Grnds TPS,IAT,Crank Cam sensors,clt, computer cable, power. There 24 rules completed no errors .some help would be nice Thanks!
Waiting two of your working days three of mine,--- so far, for help is of no use to me. Will most likely book this experience up as an expensive learning curve.To say that I am disappointed is a rather large understatement.
The software is running alphaN, instead of speeddensity, that´s why the mapsignal is the same as TPS/skassa
Thanks, so what do I get into to change this?
You might want to setup a build page on the forum.

In any case your alpha-n rpm must be 0 to the ecu to run
speed density.
You should find this in the Alpha-N/Speed density settings menu under the Base settings menu
Thanks sorted that bit, will consider forum idea
