So are you doing this via sending in the factory ECU for reprogram? The Alpha-N technology of the stock ecu is about as smart as a chalkboard eraser, primarilly operating via throttle position and rpm, offset slightly via manifold vaccuum (not pressure) and coolant temp (barely)?
With all due respect, just pulling timing across the board isn't a good idea for a boosted motor, when there's no boost reference signal or MAP sensor to the ECU. It's not very often that two boosted systems are identical, in identical conditions, so how does it adjust for what the engine actually NEEDS, or how/can it be tuned differently for a .5bar boosted system (7.2psi) or a 1bar (14.5 psi) boosten system, or is it a fixed adjustement across the board for any system? Something is better than nothing, I'll give you that, but if pay for this, can it be done differently for either of my boosted sleds with different boost levels?
I've seen it posted that you've made it rpm/load based? How? The stock ecu has no provisions for a positive value MAP sensor, and simply adding a positive value MAP sensor puts it's reading beyong the OEM calibration range, in which it has no idea what to do with such sensor values? Is your system an actual re-flash of the stock ECU, or a slight of hand, plug and play harness to fool certiain input values? Unless you've decoded the Mitsubishi ECU operating language, I'm not seeing how you only change the few things you do, when if you have developed software to actually re-tune the ecu, why not go further with with the other parameters that Yamaha doesn't use within it? I'm sure you've figured out (not saying why) that it's not the only thing that ECU is used on? Doesn't sound to me that it's a software based change, but rather more like a "resistor" based modification for the affected sensor inputs? Either way is completely your perogitave, and while marginally effective, you may consider being more transparent with your methodology as there are may of us that understand this technology very well. If it is in fact a re-flash, it would be nice to know the difficulties of reversing the modification if the need should arise, or if this is a permanent modification, unlike a piggyback controller whch can simply be unplugged?
Running a boost referenced piggyback can control fuel requirements, but having timing and fuel controlled by different "boxes" is a recipe for complications since one hand doesn't know what thte other is doing, and neither knows what it really should be doing. I do work with boosed engines and ecu programming for a living, and again, with all due respect, I'm more than a little bit "fuzzy" on the loic and excecution of this system, and for the justification of customer cost?
While I know you've been working very hard on it, and I have to praise the efforts you've made, I'm only touching on what I think is a logical and technical topic to justify the price you are asking, when this is something that still must be used in conjunction with a fuel tuner, only retards timing via rpm (load based isn't possible without additional components, and the OEM ecu wouldn't recognize them anyway) and isn't something that can be removed easilly if the user needs to in an emergency?
Please describe in somewhat greater detail what this entails, and what will make us spend hundreds of dollars on it?
