Hi there Steve

Thanks for the help.

I am intrigued that c. directs to adjust the Mode #3= at a MAP below staging.

Tracy’s notes say at approx 23”.

I thought mode #3 would be for above staging.

 

I’ll go back and re read.

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 pr= op


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 a= pprox Lamba of 1 on Wide Band
4. Set Idle of approx 1200RPM Adjusted Injection Dynamic Range - Mode #2 fo= r same.

All OK to this point. Adjustments made in Mode #2 and #3 of EC2 reflect cle= arly 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 mi= ssing 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)
