Bill,


Today I spent some time in my plane trying all the permutations and comb= inations of applying power to the primary injectors, secondary injectors, a= nd grounding EC2 pin 30 with the cold switch.

As a result, my guess is that this behavior is most likely not an i= ndication of a problem to be solved.

Bill,


Turning on the cold start switch is intended to give you a muc= h richer mixture when both the primary and secondary injectors are enabled.=   So your system is working correctly in this regard.


Disabling the secondary injectors with the DPDT switch is intended = to both cut the power to the secondary injectors and enable the cold s= tart function (as if the cold switch was turned on).  This should have= no effect on the engine at MAP below the staging threshold since the engine would be running on only the primary injec= tors just like it was before flipping the secondary disable switch. 

Your previous statement:

"= With the engine idling at about 1400 rpm, and the mixture at about 14.7, I = turned off the secondary and the engine ran a little differently and the mi= xture went to about 13.0."

is troubling since doing this should have had no effect whatsoever. = ; Is the mixture change persistent and reproducible?  If the mixt= ure eventually (within a few seconds) returns to the original value, then y= our system is most likely working correctly in this regard too.
