this is just a thread to discuss something that i have been pondering for a couple of weeks now. but first a little story-
i recently bought a new motorbike and put a new exhaust and air filter on it. to maximise the performance gains i decided to get a fuel controller. i ended up buying a Bazzaz brand fuel controller and also an o2 sensor with self mapping module. this ecu piggy back/fuel controller comes with a wiring harness that intercepts the signal sent from the ecu to the injectors, throttle position sensor, gear position sensor and the crank position sensor. to install it all i had to do was remove the plug from the injectors/sensor, put the bazzaz plug onto the injector/sensor and then the factory plug was inserted into an extra plug provided on the Bazzaz wiring harness so as it would not interrupt the signal sent from the factory ecu.
why does this not exist for cars? it may, but i have not seen anything like it. the fuel controller cost me less than $300. if you want to get the auto tune controller with o2 sensor then that is an extra $250. i ended up buying both, plugging it into my laptop clicking on the start log button and went for a ride. it keeps logging data until you click stop on the laptop when you reconnect once you come home. even if you turn off the ignition it will resume once you start riding again. it really is faultless.
here are some photos of the system if my works dont quite describe it well enough
supplied harness, which for my bike controls both sets of injectors which other brand ecu piggy backs do not

it comes with the capability to store 2 fuel maps which are switchable by removing this wire, or you can buy a push button from Bazzaz. this has been used to run a map for normal fuel and also e-85

the fuel controller itself is generic and not specific to any vehicle. with some wiring know how and imagination i cannot see why someone couldnt wire in the 3 required sensors and the injectors and be on your way? the actual tuning of the bike is dead easy, just set your target Air Fuel Ratio and go for a ride/drive. come back and retrieve the logged data and it will tell you where you are lean/rich every 500rpm and 5% increments of throttle (as you can see in the above photo). From there you can apply your own changes or just accept the program's recommendations and apply all. you can also select groups of cells and smooth the data automatically to eliminate random spikes.
i am in no way involved with this company i would just like to get other opinions from people who think this can/cant be done?
