Yes it is still needed !

So Yuri, sorry it took some time... 
I got the data out of a 4DP-10 which was the TZ 4DP2 from '93 . It can be seen that they used a very high numbers of ignition timing because of using the AVGAS fuel. The blade PV open very rapidly compared to the rotary ones.



Attached the excel file..

Thanks
Excellent work as usually ...

I can't thank you enough Juergen. That is the exact model of my 4dp.
Ultimately I will run it on a Zeel. Thanks.

[Yuri]

A 4dp-20 cdi will be interesting to compare

9A looks similar to what I ended up settling on at the dyno with the 3MA
99 unleaded

[Yuri]

Can you remove the 7k one that is not a 100% TPS

You gotta love that 4dp curve. It says "I'm designed to go like stink!"

[Yuri]

We must get neal to send his 4tw cdi to see a unleaded curve

Hi guys, thanks for the feedback. As Yuri wrote, it would be very interesting to see a "unleaded" curve. That should show some lower values at least around peak power...
