Understand WhatEverYouDoYouDoItAtYourOwnRisk
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.
Basic info
- number of cylinders
trigger
- primary trigger = HALL
- pattern= 7 teeth rising 38deg BTDC number 1 [ can shift if this is not early enough][ sensor gave a better signal on rising,[wide tooth]]
- secondary trigger cam= HALL
- pattern,= single tooth rising TDC number 1[was set up for VR]
Ignition outputs
number,=7 stick coils, inductance [not known ]
Injectors =7 = 225cc High Z
Discussion
- Is there a manual directly relating to VemsTune 0.10.14 I am finding it impossible to go forward without better information.
- it has a help. It has many features, but the basic features are not hard to handle. Tutorial is in the works (separate manual other than the help is not planned: everything should be in the help).
Basicly the Members page have answers but generally don't say how they got them it is also a pain to wade through such a lot of data and not really gaining much.
You will not be able to set the parameters one-by-one. We will use a starting setup, and modify the bits according to your wiring. So:
Start by describing your system above, THEMATICALLY organized by subsystem. So we can help you get a starting setup. Note that even the cylinder count is missing !
Fill in this page above.
It now seems that the MAP guage on main screen is directly controlled by the movement of the throttle
The software is running alphaN, instead of speeddensity, that´s why the mapsignal is the same as TPS/skassa
- correct, if set in alpha-N mode (than rather "load")
- will be speed density if settig both hybrid_rpm to 0 RPM
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
