Subject: [FlyRot= ary] Re: more staging and tuning

Interesting results Steve.&n= bsp; I didn't think a simple across the board increase would be that effect= ive.  In view of your earlier results I made a minor change to the EC2= /3 software to bump up the injector pulse width but only when the staging p= oint is reached.   This only applies to the setup for same sized = primary & secondary injectors.  With the much larger secondaries o= n the 4 port Renesis the mixture goes rich instead of lean at the staging p= oint (unless  Mode 6 is adjusted to compensate).

I have not fli= ght tested the change yet.

Ah, Ok Steve, thanks for the explanation.&nb= sp; That's when your adjustment was made (with pulse lengthening HW) in ord= er to show the results on the right hand side of the plot - got it.

Ok, makes sense that if adjusting the map takes care of the stagin= g "bog" then it=E2=80=99s the equivalent of adding 1.2 msec (fuel equivalen= t) to the values in the Fuel MAP.

Ed,

Those perturbations you see are the res= ult of engaging the pulse width addition hardware and the readjustment of m= odes 3 and 2 along with a momentary manual mixture change that was unnecess= ary.  I should have labeled three regions on the plot with the area yo= u are referring to as a readjustment period.

=0A

 

=0A

That plot was= a quick attempt at showing the effect of the pulse width addition in a sin= gle session.  The adjustments were probably not the best since it was = cold, windy, and our latest snowstorm was just getting started.  Since= this data was collected in my back yard, I try to keep the sessions short = for the neighbor=E2=80=99s benefit.  So far, though,  the horses = just across the alley are the only neighbors that have shown any interest.<= /SPAN>

I suspect that adding the injector lag time is a large par= t of what adjusting the MAP table is doing when using either of the two tun= ing methods described previously.  The second method may be easier jus= t because the step in the table at staging has already been eliminated.&nbs= p;

I presume the perturbation we see in th= e right side of left plot (Tuning Plot1.jpg)  as you decrease engine r= pm (and I see a tweak of the manual mixture control -- perhaps to keep the = engine from dying?) - the O2 sensor bobbing between rich and lean.  I = do not see that pertubation on the right plot -  is this (bobbing= between rich and lean)  due to the controller causing the injectors t= o actually cut off (not open) due to the 1.2 msec delay not being compensat= ed for???

If one = had the controller map math, it might be possible to add the "1.2msec"= of fuel missing by increasing the MAP value in each bin???  Howe= ver,  I guess (even if possible) it would be easier to compensate by u= sing your method 1 or 2.
