Programmable ignition

This looks like the thing all us LPG nuts are after:

Website is a bit light on detail, air/water temperature correction, MAP sensor? Looks like its PC programmable and can hold 2 advance curves. Cost $330. Anybody game to experiment?

Finally! Thanks heaps Dom. the version thyve got is only 2 bar range so no god for decent turbo setups.

uses rpm, map and an aux , 2.5D

Next model will have 6 bar range $400? Full 3D Tunings .,.yeehaa

I thought 2 bar was about 28psi? If so that's plenty for me. Did you find out if they have air temp correction?

Nah not quite. it has a two bar range, this includes vacuum before boost.
i dont know how much vac an engine generates before boost, but you could use it with some off boost compromise if you werent running too much boost.


i want 17 to 22 psi so i have to wait for the next version.

Yes the aux input is mapped thus if you use it as air temp, it acts as barometric correction.

Pumba.

My motor has about 16 inches of mercury vacuum at idle. I think that is a little lower than stock due to the cam. It has about .450 thou lift and maybe 10 degrees more duration than stock. It was sold as a GRA Stage 1.

I don't know what that means in terms of the programmable ignitions 2 bar range.

Dunno bout mercury vac can someone enlighten us?

well boost is pressure right ,turbo/supercharger
then you get no pressure the point were boost begins, hard to explain this.

then thers vac , the engine is triyng to ingest more air than the turbo/throttle allow. anything before boost, eg idle.

imagine it as a range, so:

-14.7 -7 0 +7 +14.7 psi thas a two bar range

just dont know how to convert16inchs of mercury to the above.
