Nope....even custom bins take only 2 mins after the initial install.

Just make sure to shut off ignition upon completion and wait until the DME goes into sleep mode before restarting engine (3 mins).

Otherwise, you may find the tranny gets stuck in 3rd gear for a few hundred feet

I am only talking about DCT. AT is a complete different world. As i understood just set everything to 0 and it should work fine.

Has anyone tried the Clutch intervention correction in an AT to see what it does?

Ive already read it. I didn't understand why he said he didnt know when it applied to AT and DCT. I assume throttle blipping applies the same in manual mode.

I am running further customized values for weeks now without issues and shifts with sport button on are brutal awesome. Don´t expect people to share their final values here though.

I don´t understand what your tuner is talking about. I thought tuning knowledge is something that you gain due experience and testing.
I tested for weeks with tons of flashes to understand.

Your "tuner" shouldn´t be working any different. Of course he will say "Bruh. I have no DCT car" ..

Unless of course your tuner is RFP. Then just wait until he can steal values or finally finds mine and adjusts 0.00x in the values.

Your shifts are brutal awesome in sport. Good to know. Is this full throttle, part throttle or both? Quicker shifts you mean? Did you have to change all the tables to get the effect or just the basic correction?

Ok thanks

(i assume you meant MT)

I have I8A0S and a MT, i was about to give a try (zeroing the tables) with RFP stage 2 map like Ilma, but i am a bit afraid with the 2D59 DME error thing ( explained on post #1) that make the throttle pedal unresponsive (it could be a bit dangerous on open road).

Anyone found a solution so far for this problem for I8A0S (with MT) ?
(or running it with no problem?)
vtl mentionned the car that triggered this had a single turbo and a custom bin, maybe it runs ok with a OTS map & stock turbos?

I also have I8A0S and 6MT. Zeroed out tables on my BMS E85 bin the other day and have not had any issues so far. Running stock turbos.
It wasn't as much of a difference I was expecting in response though.
Low RPM (1500-2500) feels the same. But above that if I stab the pedal it definitely feels like the throttle plate opens faster. Exhaust note has more of a grunt on roll in.

Okay thanks, cool i will try as soon as possible

I thought it was the opposite, like feeling most of the difference at low rpm when looking these tables stock values , it seems to already move towards 0 at high rpms, and higher values are at low rpm. (Assuming columns are rpm ??)

Did you zeroed all tables? basic corrections, clutch intervention and vehicle speed?

2007BMW335i · 06-26-2019, 01:15 PM

I read through but may have missed it. I'm I8AOS AT, can I locate the tables with the IJxxx.XDF in the original post?

Also I'm just getting started with my own custom tune, I'm still 20 whp short of a Wedge (Ken) custom tune. I can't figure out how to look at his special MHD map. (which I understand) But I want to be able to do this myself.

The Tuning guide I'm using mentions a Load to psi conversion and a Psi to load conversion. I can't find that in my XDF. I have a N20 tmap and MBoost in MHD but I can't figure out how get past 22 psi with a 220 load. I saw posts about custom map conversion and split load tables, but that info was quite old and having an auto trans I don't want to report low loads at high boost. Any tips?

I'm currently using map conversion 7.7 @ 0.5v and 47 @ 4.65v (should be 50.27) thinking that is reporting 3 psi low at 36psi which will give me about 1.5-2 psi over at 22 psi, this is not the way it should be done, I know that much.

Yup all tables zero except Basic correction-Vehicle speed was set to .001 across the board. That was based on what I saw other users MT tables were set at. I did reset throttle adaptions after flashing the bin. I cant remember if I've seen that mentioned in this thread and if its recommended or not. I reset adaptions after a flash out of habit.

Ok thanks

I flashed the RFP stage 2 to test it, honnestly i don't see much difference between RFP Stage 2 and MHD Stage 2+.

Next step is that i will take the throttle value from the 1M bin and will apply them to the RFP bin to test

I will report asap.

brakthru · 07-09-2019, 06:54 AM

Ok guys, my tuner updated my maps with all throttle values zero. I've been running these values a few days now. Car drives much better. Acceleration is near instant and shifts are quick and crisp. Accelerating in and out of corners is much better especially mid corner. Traction control seems to be more relaxed. Car feels more relaxed, smoother and normal. Easier to spin or get the rear end out. I must say the results I'm giving is with the BMS pedal tuner. If you don't have it, I would recommend it. Combined with the throttle tables, the car is amazing and fun to drive. I have an Automatic trans and use stock boost characteristics. I don't like linear. I'm running xhp stage 3 with no weird boost oscillation. All of these features combined truly transformed the car.

I have tried the throttle tables without the pedal tuner and it still makes a nice difference. However, the pedal tuner now actually is allowed to work much more effectively like it should. I can't wait to get in the car everyday just to drive it. Feels great!

Also note, results may vary slightly depending on how your tune is setup.

Hi all.
Old thread i know, and i apologise in advance for it.

Ive applied these changes to my BEF .bin, and damn, the smoothness is incredible, and it works amazingly.

I do however have a question,
I have a 2009 335i E92 with DCT.
sometimes from a standstill when i begin to accelerate, the car bogs down, almost as if it wants to stall.
I am not sure whether to atribute this to the DCT, or the engine, but it was happening before i did the updates to the throttle as inidcated in the thread,

haas anyone ever had this issue/quirk? id like to find out if its hardware or software related, but i cant be sure, im probably shooting in the dark with the question, but who knows, worth an ask.

Thanks guys

Jeffman · 07-11-2019, 10:03 AM

Anybody try this yet on a 335xi 6AT IJEOS with MHD/MOTIV FlexFuel, xHP Stage 3 and xDelete?
This is my setup and I will be experimenting with this in the coming weeks. Like to know if any others have a similar setup and how setting the 6AT tables all to zero has worked out so far.

riczon.335i · 07-11-2019, 12:58 PM

Jake @ Motiv is currently custom tuning my car at the moment and he will be adding these tables into my tune once we have dialed things in. I'll report back once my tune is refined and ready to go.

you should create an own thread with a proper title. To me it doesn´t sound to be correlated to this topic here.

Anyone know if MHD is planning to integrate this into the OTS maps?

They've indicated it will be a flash time option "at some time in the future"

studio54 · 07-17-2019, 04:42 AM

So in the RFP Stage 2 bin, I zeroed all the tables except "Basic Correction Vehicle Speed" because it's explained in the first post that it only affect neutral if i understood correctly.
(135i 6 MT).

After a road test, it made a difference, but not a lot, i really feel it in first gear, and a bit in the low rpm with other gears.

Like N54_ABQ, it's not a big difference with mine.

No errors for the moment.
