Age old tech mate, BUT some ECUs don't offer much in the way of control, for example Ducati ECUs let you create as many throttle positions as you like so you may make changes to the fueling at as many points as needed, others only offer low, mid and hig, others just the overall O2 levels and so on.. It's always worth asking how fine of correction your agent can offer when mapping the stock ECU! Also some software like Tuneboy can let anyone interface with say Benneli or Triumph ECUs with no hardware, the BIG factor is the dyno opps they often don't like to work with new or unfamiliar software that's where DynoJet do we'll as most dyno opps know it and can map it...almost a standard now... An example of skilled dyno tuners is Chris at CJS Ducati, he has made and taken a LOT of time to read the raw code with Ducati ECUs and can map them as fine as he likes for example PCV can map 10 throttle positions at each 250RPM he can set as many TPs as he likes when ever he likes, he can also change fan trip temps and so on much like Tuneboy...BUT he is about then ONLY one that can map it! There are many high end ECUs other than PCs etc that again need high levels of skill to program and map...it's endless....just depends on what you want to achieve, I see in time to come user programable self mapping ECUs as standard.. And some ECUs can NOT be mapped the likes of Honda don't like people hacking into the fine work they do and make an effort to prevent it. Tuneboy http://www.tuneboy.com.au/
Thanks for the reply Arthur, it's reported as through it was some sort of break through and mentions BSD and JHS. More info to follow next month. Trust Honda to be the awkward b'stards.
I think a few manufactures play safe with the "code" they write into an ECU, in the early days of the new blade I read they use some sort of algathrithem to control wheel spin based on engine revs (it looks for peaks in rpm data and smooths them out depending on gear position such can be seen when observing the upper injectors on the rr8+), it's not traction control as such as that's normally done by front and rear wheel speed as we all know (real TC) some cheaper traction control units use the same tech but as far as I know Honda have used such tech to make the blade so good traction wise, at the time it was called "antispin" no one ever talked much more about it as tbh I don't think most have a way of reading the raw code in a Honda ECU for example I say all this as IMO it shows that the ECU is a hard nut to crack and the speeds involved processing wise make it hard to monitor what's going on.. I'm kind of trying to cram a whole days convo of ECU chit chat into a quick post....lol I think the mags are bringing to light that more and more systems and software are on the market that let dyno centres map some stock ECUs and they like to cover some old ground...lol
