My question was:  if the MAP table gives 14.7 A/F ratio with the manual knob in the 12:00 oclock position, what would be the most likely A/F ratio with the knob all the way clockwise?  Does it have the capability of richening it to 12.65??

The short answer is “Yes, and beyond”.

 

Now I have more questions.  I went over and copied down the information in my MAP table today.  I was surprised to learn that the manifold pressures for all addresses from 0 to 63 were set to Zero.  I expected to find actual manifold pressures in there. 

My understanding is that in that range of the table it chooses the table address based on rpm.  Once you tune it in that range the correction numbers will likely not be 0.0.  For my setup it never uses cells below about 17-18, or above about 47-48 where the rpm and MAP fall outside the range; so those cells are 0.

 

I also discovered that staging was not set.  At least, there is never an astrick showing up above the V in Volt.  I assume I can not change the staging unless the engine is running???   All this was done with the engine not running if that matters for any of the data.

You will not see an * unless you are in track mode with the engine running.  The stage point can only be set with the engine running, and at the MAP where you want it to stage.

 

My Renesis engine has not been torn down, so it still has the factory nominal timing setting.  Does anyone know what this setting is??  The timing adjustment setting on the EC-2 is set to Zero.  Due to some of the recent discussions on timing, I am thinking that may have been a factor in not making as much power as others when static running.  I have been only able to get 53-5400 rpm, while others could get over 6000.

Set the timing as instructed in the EC2 manual.  Assuming you have 2.85:1 redrive you should have over 6000 static rpm (I’d say closer to 7000); if 2.17:1 you’re about right.

 

Hope this helps,
