For those who are running dual lightspeed 11 ignition systems. What is the drop off on A and B you are seeing during runup at 1700 rpms?
Thanks

For both runup (not really necessary) or in cruise: Amost imperceptable using Van's tach.

Should be minimal drop

Try cleaning or changing plugs. Klaus showed me great technique for shutting down. This has made hot starts and fowling non issues. Lean for 20 seconds at idle the. Turn off ignition at the same time you ICO fuel. When you go to restart don't touch mixture until engine fires. Works great every time.

Ditto that. The interconnect seems to compensate quite well if one box or the other is off.

On a 1.4 hour flight in leaned cruise the drop off on both A and B was 60 rpms each.
At 4500 feet these were my numbers:
21.2 MAP
2300 rpm
oil pressure 74
oil temp 178
CHT 343/338/333/338
EGT 1333/1388/1326/1388
fuel pressure 26
5.6 gph at 64% power
O320 160 hp Lycoming Fi dual lightspeed 11

Return trip: Leaned
3500'
20.4 map
2320 rpm
oil p 74
oil t 180
CHT 351/348/342/345
EGT 1317/1411/1318/1368
152 mph GS 163 6.2 gph

I still have a drop of of 60-70 rpms leaned 1700 runup on A and B.
Any thoughts? The plane fly's nice and smooth in cruise. The stumbling on final and taxi is concerning and can be helped somewhat by leaning.

What is your secret? How do you get 64% power on 5.6 gph?

 

[sirlegin]

O320 fi dual lightspeed with a Catto 3 blade prop. I get the same mpg as my Mini Cooper
It's not an anomaly, Walt can verify as he is my go to man.
