Welcome Timothy,

 

It is great to hear about your project, especially so since you are only= a couple of hundred miles away.

 

Another thing you might consider trying in addition to Ed's good advice,= is to utilize the injector backup function.  With the engine ope= rating below the staging MAP in the normal configuration, it was only using= the primary injectors.  If you force the system to use just the secondary injectors by engaging the injector backup= configuration, this might tell you if one or more of the primary injectors= is not working properly.  Of course it is possible for one or more of= the secondary injectors to also be malfunctioning, but that would be unusually bad luck.

All,

  This is my first post to the forum, but I hav= e utilized the archive to gather information and assist me through my RV-10= build process.  All the information in this forum has been tremendous= .

The EM3 was working as advertised and oil pr= essure and temp was excellent. 


I did another start today, still had to keep the col= d start on.  I quickly changed it to MODE 3 and attempted to increase the injecto= r flow rate.  This was a task, she did not want to run and boy was she rough.  I continued to increase the injector flow rate, but I could not get to idle= smoothly.  I went back to MODE 0 and turned the cold start back on and she smoo= thed out.  It was 95 degrees today here in Colorado Spring and I shut her down = as water temp reach 200.
