    I've been messing with this table for a couple weeks now. For me it added low end torque off boost. Only reason I didn't post about it was I'm getting hesitations after messing with it but I'm 85% sure its a hardware issue. (About to go do injector's now, I have 4 index 2's in there right now :scared-eek: )

    I'm starting this thread to compile knowledge of all tables related to Torque and Load in the DME. I already believe the "Requested Torque (Driver)" table has been defined / used incorrectly, and have started that thread here: http://www.bimmerboost.com/showthread.php?68690-Requested-Torque-(Driver)-Discussion&p=656853#post656853 I made that separate for now, as to compile the testing results strictly limited to that tables changes, in one place. Two other torque tables I was able to deduce their purpose from the DAMOS (I'm fairly certain). Torque Loss (Homo) and Torque Loss (Strat). These tables should probably not be modified. It appears they are actually modeled torque losses due to friciton / drag inside the engine. Cobb missed one, as there is a third as well, (Homo+Strat). That just means there is a modeled torque loss for each of the engines 3 operating DI strategies. The only time I could see changes to these tables being useful is when load is being scaled. Then you could copy / paste say the 200 load vals up a column or two, to where the scaling would place it, then interpolate out those vals to the "now empty" 160 / 200 load cells. More to come.

    So this is interesting... in the DAMOS, the table "Requested Torque (Driver)" (many of us are unsure of it's exact purpose), it's table data is defined as a % (of torque), not an actual torque value, as it was defined in Cobb and in our XDFs. Also of note, in the DAMOS it is called "relative desired moment at rear wheel", aka. requested torque % to the wheels. This would mean, with our current values, at 100% pedal, we are only requesting 73.8% of torque. The DAMOS calibration for this table is also different, in that it requests a full 100% at 100% pedal, along w/ a different gradient at the various speeds. I would like for you all to test these values and report back on anything you notice. Before / after logs showing requested torque, actual torque, requested load, actual load, boost set point / target, and boost will be very helpful. I think this table may help out low end driveability, as well as maybe even increase top end power :) I am testing as well, interested to hear what you all think. Here are the values to try:

    Are there any JB4 guys who have logs of a type4 bog coming up before these table changes, and not coming up after? I don't see how changing calculated torque is going to effect a type4 bog but would be interested to see logs of it in action. Before the knock tables we used a similar technique to force load really low (with torque higher) to get down to a less sensitive part of the knock tables.

    Ahh ok, well that makes sense. As the cars algorithms trace the load to torque and start hitting the bottom right of those tables, it would approach the torque ceiling, and start dialing back setpoint. I never used BB so I never experienced this. I jumped straight from Cobb to MHD, my ceilings were always way out of the way. Load and mg/stk of airflow seem to be the main calcs in the DME for boost target setpoint, it seems the torque mon. stuff can reduce it then if it approaches a ceiling val.

    The Epic Road Trip 2015 was a great success. For those who missed the event you missed a truly EPCI adventure. Over the 10 days the group was together we covered over 1600 miles and saw over nine national parks and three state parks. One thing with these trips is there is no way to really recap all the moments of the event. While the images help show you the sights and who was there, it cannot convey the stories shared and the new stories made. For example everyone there if you ask about Fosters you will hear a great story being told. The images below are just a glimpse of the 9000 images posted to the website. Feel free to explore the images and hope to see you in 2017 for the next Epic Road Trip. See all the images here: http://www.raddrives.com/albums/2015-Epic_Road_Trip/Tom/index.html ----------------------------------

    It changes it on a flash only map too! The DME references the load to torque look up, afr to torque look up, torque decay by RPM, etc, etc, to determine its boost set point for any given load target. Part of this process is working through the torque limiter tables which is where the load to torque table is directly applied. Originally torque was capped at ~500nm and we would scale down the load to torque to "increase" the set point. I haven't looked at the table changes but based on the logs I'd presume you're doing the opposite here, increasing the load to torque calculation. When you do this with BB where torque is capped at ~500nm, then the result is the boost set point dropping to stay under the torque maximum values. On the other hand if you do it on MHD where you've set the torque cap at 1500nm, then it won't change the set point as you won't be coming up on a torque cap as easily. In short, if you want to run those values for some reason make sure the torque ceiling is also raised well out of the way. Which requires MHD.

    Thanks, I'll give that a try. I have a mutimeter but I can't remember how to use it. I'll have to read up on it again as I suck at electrical. He's the main guy helping me this far over on the other forum That's what I'm thinking too but now it won't go away. Those two codes won't clear anymore and I can't drive the car. I'm going to try to swap CPS sensors next. Luckily my other car is a 535i so I don't have to buy parts to diagnose. 1. Logs are on the other thread. Low pressure side is fine. High pressure is extremely low. 2. I doubt our issues are linked but who knows. No, I don't have any issues filling up. Thanks for the input. I've tried two tmap sensors, stock and the N20.

    I think the axles(DSS) and diff have been okay in non XI styles(wormgear) I think it was the drive shaft couplers that have been breaking if I remember correctly. But when launching aggressively who knows what kind of weaknesses will be uncovered. Who knows, suspension might become a popular upgrade again :) Its interesting how some mods/upgrades fuel the rest of the aftermarket

    Okey Guys! I have some good news:D Sorry for my bad english hope you all understand! I believe the people have this problem drives a Comp turbo with a VM kit right? blue smoke when off trottle or WOT. You may find out that the oil return was quit difficult to install (because of the hard return line) and what ive seen the most people have there oil return on the side (so not on the bottom) because this was the easy way to do! Than it looks like this: And you guys have these problems to i think: So allot of oil in the compressorside and turbine side! I was thinking how is that possible. and i found the problem! its because the oil return nipple is not 100% straight on the bottom. A small oil film stays in the middle housing and presses true the seals when off gas (because than there comes space between the wheel and seal) and press it true the sealing. Now i cut off the hard oil return at around 3inches just after the corner and to the block i used a flexible hose that Payam delivered with the kit (normaly uses small piece down under) When the nipple is on this place you may find out you have really less space because its close to the T4 flange and close to the compressorhouse (to mounth te bolt). But there is a perfect position! Now with the oil feed on the top and the oil return down under it looks like this: This helped me and i have no more blue smoke or oil burning :laughing-rofl: Hope this help you guys! Kind regards, Marco Netherlands

    Thought I'd share some details on a project I've been working on. It's a bluetooth enabled ethanol content analyzer kit, with an additional 0-5v output for JB4 integration. Here's some pics of the OEM modified fuel line: Quick connect fittings installed for the ethanol sensor: Bluetooth data output: JB4 data output displayed over meth gauge (using the pin 15 meth 0-5v input): Also logging correctly over the meth gauge: If anyone is interested, I'm selling the individual components and a complete install kit: http://bimmerboost.com/showthread.php?68688-e85-bluetooth-content-analyzers-and-installation-kits!

    EDIT - first and foremost, this DIY kit is AT YOUR OWN RISK. Dealing with fuel is dangerous, so please use your head... Hi guys, What you see here is my ethanol content sensor installation kit. This will allow you to install a continental flex fuel sensor in between the gas tank and the engine compartment. I have modified the kit slightly to now include 100% OEM fuel lines that are modified to accept the flex fuel sensor. This will maintain 100% reliability and safety. What you get - 1x modified OEM fuel line with ethanol sensor quick connect fittings to maintain stock fit and form 1x preassembled harness (power/ground/signal leads, 3 premium bullet quick disconnects, GT150 series sensor connector pinned and weather sealed) to run from content sensor to the DME box 1x allen head bolt to mount the sensor to the undercarriage 6x zip ties to fasten the content sensor harness 1x 12 volt to USB power module 1x USB cable 1x Bluetooth enabled content analyzer with harness quick disconnects The analyzer connects to any Android smartphone via a free terminal program and will broadcast your fuel composition in ethanol percent. It also has a contaminated fuel trigger. I now have e82 and e90 kits worked out and ready to go! Since I hand build these, they are put together by order. Lead time to ship is about 3 days. PM me if you'd like to order and I'll provide paypal info for payment. Costs are as follows: $130 shipped for the OEM fuel line with content sensor quick connects attached $55 shipped for the analyzer $35 shipped for the harness Or $200 for everything. The analyzer is 100% upgradeable via USB for any future code enhancements. I'll work on a prettier app in the future, but as of now it does what it needs to - tells your ethanol content, fuel temperature, sensor frequency, and sensor amplitude. You will need to provide your own sensor. They can be found for around ~60 dollars. The part number is 13577394. I'm going to building these on a per order basis, so everything will ship about 4-5 business days from time of order. Here's some pics of the kit: Full kit (note - I hadn't put the all the ends on the hoses): Content analyzer with premium bullet disconnects: Content sensor wire harness with premium bullet disconnects: Here's some pics of installation. Basically you remove your factory fuel feed line and replace it. It's very straight forward - the trickiest part is the fitting at the regulator. Remove the grey plastic C-clip off the factory junction: Press the blue plastic release into the quick disconnect housing and pull the line out. I removed the protective bracket in this pic for clarity, but it's not necessary if you work at it: Install the short line into the factor female union and reinsert into the guide clips: Install the content sensor like so using the provided bolt: Remove the back seat and regulator cover. Release the factory fuel line by GENTLY lifting all three of these clips with a small screwdriver: Unclip the factory fuel line from the undercarriage guide clips: Once unclipped you can pull out the factory line. Feed the longer line up to the gas tank from the bottom of the car. I was able to do this without issue, but it may be easier to feed the female side down instead. Make sure you end up on the same side of the factory clip that the factory line was: Insert the new line into the factory clips: Make sure you leave enough slack to prevent from rubbing on the gas tank: Connect the female quick disconnect to the content sensor. Then plug in and run the harness up into the engine compartment, zip tie where necessary: I don't have a pic of it, but remove the cowl, and run the harness in the empty channel of the wire harness guide across the engine: Insert the harness into the DME box through the medium sized grommet: You'll need to tap switched ignition and ground in the DME box for the USB power supply. I used the JB4 power wire and a ground off the JB4 harness: After that, connect the harness and USB cables, and pair the bluetooth radio with your phone. The app I'm using to read content on Android is called blueterm. It's a free and basic serial terminal program that will read out your fuel composition as text. You can see here my math was pretty close, and I'm almost at my desired e30 (guesstimating the blend at the pump): The ECA also has a 0-5v output for integration with JB4. Here's an example with the ECA plugged into JB4 via the meth flow input: This allows for live monitoring via the JB4 mobile app, as well as data logging!

    A successful AT upgrade/swap will put this car deep into the 10's at least. With enough power, this thing will be rocking 9's for sure. But before that, a lot of shit is going to break.

    The only good options I have found for mounting a escort radar detector are pretty pricey. I decided to fab up my own and it has worked great for the past year or so. Everything can be purchased at the local hardware store for less than $20. All you need is a strip of aluminum, screws, nuts, epoxy and plastic screw covers. Here are some pics it is pretty self explanatory but if you have any questions just ask.

    Still working out these details. The easiest will probably be a flash-time checkbox, so all you will have to do it set up the Load Target and Load Target Adder by Gear tables in your bin how you want them, then check the option at flash time, and everything else will be done for you.

    It ended up being a LOT more involved than a timer table, Josh@Cobb wasn't lying :) Yep, it is physically the same table, just has been renamed as it now serves a new purpose. You do not need to have the same load all the way down, you can increase it as RPM's rise, for example :) shhhh, we can't talk about this bc California lol. There may be something there though... There will be an announcement regarding this in a day or two, so keep watch. Don't want to get off topic in this thread though.
