In Chamber Testing

Do those combination spark plug + pressure transducer mimic the typical (NGK) spark plugs we normally run?
Mazda went with the surface gap spark plug design for a reason.
Do they have a spark plug that is surface gap also?
I think we all know that shrouded versus unshrouded spark plug electrodes do change the way the engine responds?

I sent the company who makes them request to make bespoke version in heat range and type I need (modified NGK) and got quoted 5k or 7.5k for one plug only! I decided to not get it lol (things may have changed since then, was 6+ years ago now). Though this was many years ago before I spent 50k on VBOX gear and my Pico scope set up.

The specific multi function super response sensor I use on the Pico is like $1+k only measures to 500psi though or 3.4Mpa can do running tests with it just not high powered ones, I am looking for another sensor that is as accurate and fast (>1% FS) and lower cost lol.

My next engine I will machine the rotor housings to fit three sensors permanently equidistant into the engine and map the whole cycle, see how excited I get haha. Can tell you from running a car permanently VBOX equipped after a year or more of looking at reams of information you do get slightly over it Then again I have been doing crap like this since 1991 (beginning of mech eng study), combine that with the internet age now where every single customer/peer is a mech eng enthusiast/expert cause of wiki and forums lol and it gets on your nerves needing to explain shit over and over in a never ending attempt to educate some cunts.

Barry how much are TFX charging now for a system? and the generic plug sensor btw (like the one you have pictured)?
