Steve:

First confirm your timing as per Lynn’s commen= ts.

Did you start with every mode set to ZERO? 1 through= 9?? Mixture knob in center???

Your fuel map is 128 bins wide x 256 bins high as in= an X/Y graph, with ZERO settings on the vertical scale.

My map is displayed with Ed’s EFISM and is 0 t= o 256 on the vertical scale; I think Tracy’s EM displays it as -128 t= o +128.

After setting Mode 3 and Mode 2, all your settings s= hould still read either 0 or 128.

At this point, your fuel flow is based on 23” = MP and 0 or 128 fuel value.

I would expect as you open the throttle that more fu= el will be required at 30” MP Vs 23” – has always been tr= ue with my engine.

Have you confirmed that you actually have a staging-= point; i.e., where the injectors flip from just PRI to both PRI and SEC? &#= 8211; Very important to confirm where it is.

Confirm both Timing and Staging; repeat Modes 3 and = 2 then use Mode 1 to tune fuel bin value at WOT.

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


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. 3. Run her up to ~23” and adjusted Injector Flow Rate - Mode #3 for = approx Lamba of 1 on Wide Band
4. Set Idle of approx 1200RPM Adjusted Injection Dynamic Range - Mode #2 f= or same.

All OK to this point. Adjustments made in Mode #2 and #3 of EC2 reflect cl= early 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 m= issing as more power comes on and is quite severe. (Not missing now and the= n, but constant)
Selecting between A and B computers (Backup CAS) makes no difference)
