I thought everything was zero=E2=80=99= ed since last program but I=E2=80=99ll go through and reset all = settings.
I thought given the parameters set at = chip program such as RX8, Staging Point and Large Secondaries I = wouldn=E2=80=99t need to play with timing or with Mode 6.
But I=E2=80=99ll go through all of them now.

3. Set Mode 3 Inj Flow Rate
4. Set Mode = 2 Dynamic Range
5. Set Mode 6 Sec Inj = Differential
6. Go to WOT and check adjust = mixture 

A = couple more questions for you guys:

3. Sounds like EC2=E2=80=99s advance curve is not flat, what = advance setting for what RPM for stock Renesis 4-port?

I=E2=80=99ll then check the staging point is at = 15.5=E2=80=9D

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=E2=80=99s EFISM and is 0 to 256 on the vertical scale; = I think Tracy=E2=80=99s EM displays it as -128 to +128.
After = setting Mode 3 and Mode 2, all your settings should still read either 0 = or 128.
At this point, your fuel flow is based on 23=E2=80=9D MP and = 0 or 128 fuel value.
I would expect as you open the throttle that more fuel will = be required at 30=E2=80=9D MP Vs 23=E2=80=9D =E2=80=93 has always been = true 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? =E2=80=93= 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=E2=80=99= m seeking to tune in our EC2 Renesis 4 port with Elec adjustable = prop


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=E2=80=9D 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 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 then, but constant)
Selecting between A and B computers (Backup CAS) makes = no difference)
