Barry,

I have number 298.   I've done 3 test runs and once she has started to ramp up, no problems.  I'm using Kero with a 5% Aeroshell oil mix at the moment.  I've got a few question related to ECU setting and these are:

1.  The idle speed being higher than the set 45k.  Idle is a little lower than 47k rpm.  I'll try adjusting the pump power down as Barry recommends.   The fuel pump i have is the stock fuel pump(black casing, grey pump head).  Is that a flight works pump? 

2.  Start cycle - from a cold start, i will get a time out warning on the first start attempt so i have to reset on the Tx and and then on the second start attempt, she will ramp nicely.  I have the throttle cut switch programmed on my 11X-zero so this makes it quite easy.

I think this may be related to the butane/gas settings and/or bottle pressure.  I use autostart and with glow plug power at 33, gas at 88% now.   Thinking of setting gas to 100% but i will try a new bottle to see if a higher pressure bottle will allow startup on the first attempt.  Any ideas?

3.  I have throttle response set to Half-Expo at the moment and i get a smooth, clean ramp up from 50% power all the way to 100%.  It takes about 4-5 seconds for WOT to come in.  On Linear, 50% to 100% resulted in a pause/surging then it would go to 100% cleanly after that.  Would adjusting the fuel pump setting down eliminate the pause/surging?  I was hoping to use a linear setting. 

Thanks in advance guys!  appreciate the help!

Regards

Rob
