    Major differences between 48 and 128?

    the 128 is the biggest ems i've ever seen for sure, at the size of a large laptop/small desktop i'd hope it is stupidly powerful lol

Then someone will inevitably say "without a basline on the same car, same dyno, and same day, it doesn't mean $#@! fail, fail, fail, you suck." My favorite part will be when Shiv's dyno numbers come into the conversation, even though that is completely irrelivant. Also, RB's, $#@! singles, Cobb, flapper valve bypass, long cranks, 4 meth nozzles, Level 10, bus driver uppercut. LOL

    J.K. now lets see those dynos.
    Nothing means %$#@, we can all just compare vehicle weight with driver in it and trap speed....dyno is a tool....

    I am not asking for a gaurentee. I am just wondering if the car will or will not pass an OBDII emissions tests.

    Probably the best comparison of overall power right there.

    Sooooo, does that mean you guys will be putting together an Atco meet soon? I'm down!

    yeah sorry i read that before, but most of it doesn't mean much to me

    i don't know the differences in really meaningful ways other than 128 has 12 injector outputs and the 48 has 4.

    ED: and the 48 doesn't do DBW throttle, and a couple of other things.

    in supras pro48 is a stand alone ecu/ems. All the stuff listed is included. 4 injectors though? We can make it 6 I assume? Is there a need. Will these injectors be in addition to the DI? If so does this mean we have to have the mani? Sorry don't know much about pro efi

    With the pro48 on a engine more than 4 cylinders you run semi-sequentialClick here to enlarge

    The power/economy difference is negligible. However you obviously lose ability to add/sub fuel per cylinder

    Is that 4 injectors total? If you wanted to do 6 in the manifold and 6 in the head (DI) that would require the 12 injector model, correct?

    Yes. However we have totally revamped the project. You guys will be getting a totally different ecu.... The 112!!!!!

    Ok guys! First off, no $#@!ing, screaming, kicking, complaining of any sort allowed!

    I personally have about 14k tied up in this project. Between shipping the car 2300 miles, shipping myself 3 times, all the parts blah blah blah. The cars staying and I'm getting back on the plane now with Angie. This is where we are...

    All of this will be overcome in a matter of weeks.

    For whatever reason BMW decided to use a 3 tooth cam trigger wheel. Although the crank is a normal 60-2. This caused 2 issues. One, we were not able to control the vanos. Two, because of one when the DME did not see ignition flyback from the coils(we were controlling them) it freaked the F*&% out and rolled the cams into a limp mode state that reduced power by at least 80%, throttle went to nill and the car was PISSED! All this took days to confirm on the lab scope and dyno. Ultimately ran us out of time on this trip. We have to get home and handle business.

    What are we doing now?

    The software engineers are going to start writing the code tomorrow morning. This is a daunting task and takes a few weeks and about 10k. DONE! In the works. This is not another project left behind like others.

    What are going to be your options?

    #1 FULL engine control! DME will only be used as basically a dash board ecu to keep all your comforts in tact. Like CA and all the other goodies. A new unreleased 112 box will have 100% engine control. Fuel, Ignition, VANOS, Fly-by-wire throttle, twin wideband, DI, Port. The biggest advantages of the new box is 3 channel Can Bus and size. The plug is on the end instead of the middle and will be significantly easier to mount.

    #2 Piggy style hook up with a pro48 and a cobb flash. The cobb will solely be used to erase DME codes that will throw the car into limp mode, rolling the cams into a unbearable state. The pro48 will give you full ignition control, fuel and throttle. This will be a much cheaper option, but obviously more versatile than all others currently. It will be especially great for the guys who already have a cobb ap. The only downside to this is that we will have to run a second coil harness to keep the factory DME from turning off DI when it sees the coils are not hooked up. Not a big deal though.

    The 3 trigger wheel was our biggest hurdle. Although our car will more than likely run a 128 box initially it will be turned into a 112 down the road. We will be trying to get back out here in 4 weeks or so. But it could possibly take 10. Just being honest!

    This was not the way we planned this trip for certain. My pockets hurt!! But everyone involved is certain that this is one of the most untapped applications of all currently. With more cars sold than probably any other.....ever!

    Any one who wants to join on thursday at atco, look for me with the matte black GTR. Watch out LostMarine. I heard about you doubling the boost. No worries though, I've got a major F*%$ You up my sleeve!! Remember, we've never launched yet and also havn't turned up the boost more than factory wastegates would allow. Click here to enlarge

    Thanks so much for the reply and honesty. I was just literally driving by the Scottsdale airport today. Was with the wife so couldn't stop in. We will wait patiently, but, hurry!

    brand new kinda custom or something?

    is it anythign cut down from the 128, or is it pretty much a custom 128 for the n54?

    Couldn't agree more about this being one of the most untapped applications around. The amount that this platform can take thus far is already proof of that. Looking forward to seeing you on Thursday!

    Wow, you guys are really putting your money where your mouth is.

    The BMW DMEs have been monitoring coil flyback for a long time - helps detect misfire due to a weak or dead coil. I don't even know what the direct injector pattern looks like. Lots of things to "work around."

    I'd pay $3000 just for the traction control capabilities of the ProEFI. You'd KILL people on a road course with real traction control holding back 400+lb-ft of torque until it's fully capable of unleashing it down the straights. It would be practically cheating. Click here to enlarge

    And I know the project has changed direction on the ECU, but 4 injector outputs would just be using 3 as phased batch-fire. I don't think, however, that CAN based wheel speed/traction control would be as fast as reading wheel speed inputs directly.
