my point is how many times are you willing to shell out £350 every time it gets tuned, (thats how much it costs me) before it's right, whereas you use the ecu that the tuner you trust knows inside out and will do a great job with all should be fine and dandy.
and besides, most ecu's that most decent tuners use are all far superior to whats offered on this site, theres loads to choose from, that are all feature rich, and are much better well known systems like
omex
emerald
link
dta
motec
bosch
hks
the list goes on
i think we'll have to agree to disagree on this one sam.
as for tuning pints, it doest really matter with basic upgrades etc,
but the likes of motec hks omex etc, wouldnt bother investing in technology that will do 32x32 if it wasnt really worth it would they,
the idea of the extra tuning points is to reduce the ammount of guess work the computer does.
I think we will, but I think you're missing my point slightly. If you read what I've said you'llsee I've clearly said that if your chosen tuner does an ECU that does everything you want then that is great, but if not you need a new tuner. Otherwise you'll only be disappointed. Plus my experience with tuning my ECU is irrelevant seeing as I've only had it done once and you can't tell if you trust a tuner without trying them. Google WGT Auto Developments and read about their reputation in Mazda circles, you'll see why I chose them.
32x32 is all good if your ECU only looks at the cell it's on, otherwise it's not needed. Interpolation isn't 'guesswork', it's actually damn accurate and provides a lovely smooth drive, as smooth as my Dads Motec powered MX5. As for the technology that goes into it, I'm not buying it. Very little technology goes into 32x32, and the vast majority of ECU's still use serial ports to tune them. You try finding a modern laptop with a serial port, you'll only find them on expensive service laptops. Also I'm more interested in closed loop capabilties than 32x32, as it's much better for getting spot on running. The numbers your tuner put in may not be right in all conditions and that's where some ECU's will trim or add fuel based on what what their sensors are telling them, even if the tuner told them something else, obviously you give it an authority level so you still control how much it can change things. I suppose what you really need to remember is that the end user is still the driver, not the tuner, and so it's them that the ECU manufacturers are selling to, and 32x32 sounds a lot better if you don't fully understand what you're on about.
As for a tuner I trust, it's me. I'll be tuning my Megasquirt from now on. Done shit loads of research and I can safely say tuners are next to muggers!
