Slightly higher CHT's - 2-4 deg C I have Map 2 at 24 deg fixed and the other Map 1 as variable with rpm & manifold pressure Leaned out at 12L/hr at about 2150 rpm at about 2-3000ft - on the fly switching from Map 2 fixed timing to Map 1 variable gives an approx 1 L/hr drop in fuel flow for the s...

Yes - got full LAA Mod approval after 5hrs test flying and then a general update report after 25hrs but all good and no problems. Regretfully my Grand Rapids EIS 4000 (what a great bit of kit that is!!) is an earlier board version without the 2 tacho inputs. Recently fitted a B&C 30A 433H gear d...

Yes thats almost correct, except I don't power down the EDIS module - only the power to the coil pack is interrupted during a/c power/'mag' checks. - correct otherwise. I did a current draw vs RPM tabulation/graph for the LAA as part of my Mod application - I recall it was about 1.05Amps at 14.4 sup...

Possibly - my article Home Brew Ignition was in the LAA Light Aviation mag in Aug 2011. If it was, I'm really pleased :D to hear that as I wanted to inspire others to try it out. I was mainly thinking of UK LAA guys but its fantastic if it has reached across the world. I also did articles on Electri...

Hi the B&C Overvolt system is really good. I use it. http://www.bandc.biz/over-voltageprotectionmodule.aspx Well done on getting the ignition up & running - I am currently getting installation approval via UK LAA (delegated regulator for Permit a/c from the main CAA). Did you similarly have ...

I have done the same in an a/c - except I kept one Slick mag ie self contained ignition. I use a relay in the power to coil pack wire. I have wired it such that the normally spring loaded closed contacts feed the coil pack in the default position. The relay coil has a permanant live taken from the c...

Number of PIP pulses

Brent /anyone Can you confirm how many teeth must pass the VRS before the missing tooth passes it in order that the EDIS4 can process and calculate the advance/spark the coil. (I realise that as a bare minimum the missing tooth must go past the VRS and for the crank to rotate round to the calculated...

seems to me the EDIS /coil sys / trigger is a lot different to the std kettering coil / points setup. On EDIS, if you slowly rotate the engine insuffiently fast to cause a spark there is no point at which the coil resistance is connected to the power supply ie O amps - unlike, as you say, with a con...

That's a big fuse rating.
My bench test showed a current draw of 1.05 Amps at 3000rpm (EDIS4) - this was MJ, EDIS & coil pak combined.

It does indeed act as a barometer when the engine is not running, since the MAP4250 sensor is an absolute pressure sensor and so measures atmospheric pressure. It is not uncommon on sunny 'high pressure ) days to see 1040 -1045 millibar ( 1 mbar is exactly the same as 100 Pa ). I suggested to Brent ...

3.2.1 Source Code

Brent Will you be making the above available.
I would be very interested in how you have coded both the dual mapping and the cranking rpm advance.
Thanks

Even simpler way to do this is to fit a 1k resistor in place of L1 as before. Then on the wiring away from the MJ plug, just connect the VRef line and the Option lines together and wire these both to the Map switching switch ( switch to chassis earth for Map1 and switch open for Map 2) Hey presto, n...

Changed the Max232 to a Max 232ACPE in a socket.
Checked it first on the configurator to see if reading & writing worked - it did.
Tried to update firmware to V3.2.1 and it worked first time and updated perfectly.
Problem solved - thanks everyone.

Steve
