Need wiring diagram for ECU on a 98 E430
The piggy back is a module that allows a laptop to make real time changes to parameters that affect the engine and performance, i'm still wondering if it will make a nice difference in performance.
I am only going with a piggy-back system because I'm not going to fully build my benz, but enough to the benz to require more/better fuel and ignition management. Supercharger is in mind, and with a piggy-back system I'm going with, I can control additional fuel injector(s) if required.
I will give you an example. Let just say you got a good breathing intake system. Hi-flow Filter, port/polish intake manifold/ port match heads. You will create a lean condition, if the stock ECU program is unable to compensate for this, it might go in to a limp(safe) mode, by allowing you to modify the signal of the ECU, you are able to trick the ECU to thinking of something completely different.
It's almost like purchasing a "chip". Only difference is that you or a tuner are able to make changes in real time, instead of having your chip reprogrammed to what they think your car needs.
