I just wanted to contribute a number for this one engine.
I have several Jetcat setups with Gaspar's devices (tele1/2/3 or FC) and I'm slowly converting to CTUs (just got two more from Danny last week) so it will be interesting to compare the "pre-calculated" (by the ECU) numbers from the Jetcats to the CTU. FWIW, I have found the Jetcat calculations to be pretty close, at least on the P200 and the P300.

Oh, I didn't read your comment as that, no worries
Its funny with the JetCats and their fuel calculation, I have found that all my P20SX are off by at least 10%, some even 30%, but P160 and P180 I have are all reasonably spot on (maybe 5% or so off).
With the CTU you can however finetune this as much as you like, I have seen a guy with a sense for details getting his close to 1% for the fuel
