Hi guys, i have been reading from this forum for far to long with out posting, mostly because i felt lost in the welth of information around...
Quick intro about myself:
I am a firstly a Mechanic with 15+ years of experience on both cars & bikes. Specialising in performance engine building / blueprinting / EFI system fitting, tuning or more recently Reflashing for NA, turbo'd, supercharged & NOS setups(both cars & bikes)
Enough about me & on to the serious stuff...
I work for a company Called Tokyo Motorsports in Perth, Western Australia, We have been reflashing Mitsubishi EVO's & the V35/V36 skyline's & 350/370z more recently delving into Suzuki motorcycles. Both the mitsubishi & nissan software have the ability to live tune. (mitsubishi software is openecu)(nissan software is Uprev)
Anyone with with enough tuning exp will know that live tuning is by far the most effective & accurate way of building a satisfactory fuel & ignition map for any given application, due to the ability to see gains or losses even with the smallest changes without the chance of other affecting factors changing the results.
I will be honest with everyone, i do not even pretend to know how to program software, but being able to use live tuning software on ECU's fitted to factory vehicles makes tuning much less time consuming & much more accurate, & a better end result to our customers.
Given all the above "drible" i would like to put it out there to the Software guy's... I & hopefully many other professional tuners would really like to see real time / live tuning added to the ECU editor software.
I would be more than happy to give as much help & information as i can to get this function added . I believe if it can be done with Mitsi's & Nissans it can be done with the Bikes.
Hope this takes less time to read as it took to right........

You could do the same with Power Commander maps but I think that misses the point.
The piggy back systems have only allowed people to live tune fuel for so long that I think many have forgotten about ignition and/or secondary throttle. We know the factory use these maps to de-tune the engine. Re-tuning it would be a lot easier if you could edit them live.

Of course it misses the point but isn't the point that you can't given the hardware constraints of the current range of ECUs?
Hi guys, glad this post has got some ppls attention..
The reason I/we would like to see live tuning in the software is 2-fold.
Firstly, Instead of auto tune...
With auto tune, we are trying to interface an external module (WB02) to an ECU that was never intended to see that signal, add that to logging software created for the ECU(which was not intended to see WB02), combine that with not knowing what other fueling maps are being overlaid to get the actual measured WB02 (accel enrich, air / water compensation...ect) and finally add in an unmeasurebale amount of delay between the O2 sensor - WB02 module - ECU - logging software..... and then to top it all off, taking multiple individual cells samples and giving a average representation.
Secondly, The idea behind remapping the factory ecu first & foremost is to save paying for an extra (box) allowing tunability,What would be the point of buying a PC3/5..ect for each bike to be tuned then only use it on the dyno & then spend extra time trying to inIterpolate the map over to the factory ecu map.
It also eliminates all of the things i mentioned above (overlapping modules / maps) Specially on any bike running closed loop fuel / ignition control. (add fuel with PC3/5 factroy ecu looks at O2 sensor whilst crusing, sees rich mixture & starts pulling fuel, defeats the purpose dont u think? not to mention it will be lean next time unitl ecu adds fuel back in..)
Ridgeracer: i will post up an extract from the Uprev software instructions hopefully that gives u more info on how they do it, it sounds very much like what u mentioned in your first reply. I would be very interested in helping you or your colleuges in testing a live tuning feature. As a workshop we have access to full in-house dyno facillity & test bikes.
