Yes; I have the EM2.  As I mentioned, it is currently using the default = correction table.  I had spent some effort during the dyno runs to correctly = map it out for my injectors and engine, and then sent the EC2 back to = Tracy to update for = use with the EM2 not realizing that the new chip would loose all the settings I = had done.  In that update I had discussed with Tracy about the = difference in the primary and secondary injector flow rates, and he made some = adjustment to aid the balance.

 

I’ve looked at the = correction table profile and it looks OK.
