Hi G= uys
Could I get some feedback on process and my thinking here.
I=92m seeking to tune in our EC2 Renesis 4 port with Elec adjustable pro= p


Steps so far (can only run for 15mins before overheating)
OAT is presently 33-40C 91-104F
Prop set course

1. EC2 Injector and Coil diagnostics all good
2. With 2 squirts she starts well after approx 2-3 revs of the starter.<= /span>3. Run her up to ~23=94 and adjusted Injector Flow Rate - Mode #3 for ap= prox Lamba of 1 on Wide Band
4. Set Idle of approx 1200RPM Adjusted Injection Dynamic Range - Mode #2= for same.

All OK to this point. Adjustments made in Mode #2 and #3 of EC2 reflect = clearly on Wideband O2.
Switching between A and B computers makes no difference.

Now opening throttle up gets us to approx 5000 rpm (course Prop) but its= missing as more power comes on and is quite severe. (Not missing now and t= hen, but constant)
Selecting between A and B computers (Backup CAS) makes no difference)
