You are prepared to lose most of the convenience functions of the car ?
I think you'll be surprised at what little is lost. If I give throttle control to the elite, ill lose cruise control, and that's it. Not too big of a deal if you ask me.

I think canbus is gonna freak out but good luck and let us know, have plenty of Advil or aspirin on hand because it's not going to be fun
As do most people. Most get overwhelmed with the amount of canbus information, I'm not concerned with that.
with a parallel install, the oem ecu still works as normal as it always would. It just wont know that it's sending output signals to dummy load resistors instead of the ignition and injection circuits
(closed loop fuel lambda target will have to be adjusted in an oem map in order to not throw codes for the long term and short term fuel trims, more on that later..)
ignition has no real feedback loop, so as long as the engine isn't misfiring, the ecu can't determine an issue there...
canbus is left with the oem ecu... it's sending and receiving information like it always has. canbus communication isn't affected like most people think.. engine electronics aren't omnipotent, they are simply input and output controllers. as long as the data input is within the limits of running correctly, there isn't an issue.
I believe he meant how long before you have results, not how much timing is in the tune
Lol, good catch. Im hoping to ve completely done by springtime. My work schedule is like 60 hours a week, so i get 8 hours or so on one weekday and possibly some extra time on the weekends. Ive still got a few more things to order and some answers to find on a few things.
Nice! Good luck to you. You're way smarter than I'll ever be. I would get scared of even starting something like this, plus I have no electronics knowledge
Hey Mitch whats up buddy! It looks like you didn't give up. Nice!! BUt, the obvious question why not just buy the tuning software that the tuners use tune your stock computer?

For a variety of reasons.
1. background, i've had a little bit of experience with haltech systems in the past. they're very user friendly, have great support, and continual support. that in itself is something you won't find with the oem software or oem reinnovative software. I dont know the first place to start with trying to find answers and instructions to doing using the software/hardware properly.
2. Flexibility. While the E55 will be getting the Elite 2500, my goal is to use it on another vehicle I own as well. (95 turbo honda civic) 1 ecu, adapter harnesses, less money.
3. More control, and better control. The possibilities are nearly endless of what I can control based on any parameter or set of parameters or conditions, as well as being able to add sensors for more control.
chances are if you're running nitrous and/or water meth on your car, you're running some type of controller, I just took it a step further... a Big step further.

I see your point, I don't know the resolution of the maps the tuners here are using. My guess is like every 500 rpm? Just a guess… But, yea haltech is awesome. you can get a lot more resolution for the fuel and ignition maps not to mention some other very nifty options.
Good luck, I am looking forward to seeing what you make of this. I am glad someone is doing this finally!
Canbus has been on several cars that have had standalones on them for years, nothing new here. Just don't cut off its feedback signals (or make fake ones) and you should be ok, MB or not. (not making light of OP's work, just stating it may not be as complex as it seems, its been already done with cars with just as complex a Canbus system)

Quoted for truth! The "its gonna freak out the canbus" talk is foolishness lol

GL on your quest sir.
Ill have a table set up rather wide. 17x17 non linear or something near it. Ypu want more cells in the idle, cruise, and light accel areas than you do in mid and high accel areas.tables woll peak at 8k rpm and 30psi. (unreachable windows, but the goal is a table setup that I never have to add to later)
