This is going to sound like just another PCV vs Bazzaz vs Flash-Tune vs ECUnleashed thread, but I assure you, it isn't.
Basically, I'm interested in reproducing the standard fuel, ignition and throttle maps for my EU (Australian) 2012 R1, so I can truly see the 'restrictions' of the stock ECU.
I put 'restrictions' in talking marks because I'm not convinced all of the gear and rpm dependent restrictions are actually restrictions. For example, having the ability to get WOT at low rpm is not going to help you in the real world - the motor can only breath a certain amount of air at low rpm. Another reason for having a 'restricted' throttle is driveability - in other words, trying to achieve a linear power curve. By nature, petrol motors do not produce linear power curves. It takes a lot of tuning to achieve a linear power curve. It means targeting efficiency around the troughs and restrictions around the peaks. Also by nature, butterfly valves do not have a linear response. Therefore it doesn't really make sense to have a 1:1 TPS vs APS relationship, or even a linear TPS vs APS relationship.
Anyway... to get back on track...
Flash-Tune and ECUnleashed claim to remove these 'restrictions', and the customers on these forums certainly back up their claims. However, I'd really like to find out for myself. And do it like an Engineer - which I am.
My first question:
Is there a way to read the OEM maps off the OEM ECU?
I'm guessing the answer is No. I'm also guessing people are going to say the Flash-Tune 'standard maps' ARE the same as my OEM maps.
Well I'm not 100% sure this is the case because a) Flash Tune is based on a US ECU, and I've got an EU ECU (which I'm lead to believe has less 'restriction'), and b) I understand the flashing process replaces the entire OEM software with a 3rd party software (it doesn't just unlock the OEM software), so we are trusting the programmers knew what the OEM maps were, and that their software can run our motors just as well if not better, which is an incredible claim in the case of Flash-Tune, where there's 1 guy vs an entire Electrical Engineering division of Yamaha with (i'd imagine) a much larger budget, facilities and knowledge base.
I could be completely wrong about the flashing process. Please feel free to correct me.
My second question:
Is there a way to intercept and manually record the ECU output signals to the sparkplugs, injectors and butterfly valves, as well as the ECU input signals from the Accelerator Position and RPM Sensors, so I could manually reproduce the fuel, ignition and throttle maps?
I'm guessing dealers have the equipment to do this, but it's not commercially available.
All of this is probably way too hard, and not worth the effort, but I thought I'd put it out there anyway.
It would be great to know what the OEM maps are for sure, instead of trusting a 3rd party. And to know what the OEM gear and rpm 'restrictions' are for sure, instead of trusting here-say on the interwebs. Then we could scientifically compare the OEM maps with Flash-Tune and ECUnleashed maps and actually see what the difference is, in absolute terms.
I'm not trying to offend anyone. I'd just like to do some experimenting.
Thanks in advance.
