Thanks for that.

So with Requested Torque Mon Factor A & B, were they not able to be changed and flashed with BBFlash? Do you suspect that a limit applied by one or both of these tables were being hit prior to changing them?

They are tables for low throttle mapping. With the checksums fixed you can set the monitors to 1.0 and then increase load as a function of pedal input for improved response and drivablity. The BB software does not properly compute the check sum when changing them thus they have to be left stock in those maps.

Hi, peeps!

Ok, here are my findings so far.

I flashed using a HTC one M8, to read the file, it took 2% battery power, about 15 mins.
To write the file, it took just over 18 mins, this took 5-6% of my batter power.

I did not read/write using a charger attached to my car.
I strongly recommend using the charger as my car struggled to start when the flashing was complete.

I'm running the supplied Stage 1 on 98 RON flash
BMS DCI's
Cobb FMIC
Stock exhaust with resonator removed and replaced with an X-Pipe + PE Mod.

Is the stage 1 flash safe with my mods?

I've not had chance to give it a good run yet....

The reason I ask is it feels insanely quick. Induction noise is so much louder, Throttle response is really nice compared to the Sedox file.
Just feels so strong.


If all is safe, ill do some logs tomorrow as its raining here :-(

Stg 2 93 was a little to aggressive for my car with VRSF d0wn p1pes and intakes.

Can you explain further? Too aggressive of timing? AFRs? Boost?

Timing corrections. Wedge said it was too aggressive for my car. Loaded 91 map and still getting timing corrections.

Are the "off the shelf" flashes customised for Euro or US based cars?

Hi Guys,

I have made some logs. How do i get them to the right people?

The power seems inconsistent, boost seems to be a little all over the place... corrections on cylinders like others are reporting.

Cheers

Gareth



Update:

Done

Timing is Ok not dangerous or anything a lot of people see -3 corrections for various reasons. If you see more than -3 corrections then you gotta pay attention.

But something is up with your boost, It builds slightly slow, but if you're on old stock turbos its possible. You might have a very small boost leak somewhere. But more importantly in the 3rd log boost takes a dump for a reason I can't see, it doesn't look like timing or fuel related. Also your PID boost management needs work you're never quite hitting target. But these are Beta maps looks like the tuner is taking a cautious approach... I think hes still working on them.. remember were beta.

Good to see the tuner is being careful.

Honestly something just occurred to me... It might be your DV's... I never run into it because one of the first things I do/I have my friends do when tuning is dump the stock ones... they're not made for more than 10 psi. I'd venture thats a good guess for the big boost dump too in log #3

Hi,

Thanks for your quick reply!
The most i have had is -3 corrections

The car has done 49k miles, so turbos aren't "really" old, i don't think

I do have stock DV's.

I just done the "reset fault code"(i think it was) on the app, took it for another drive and it feels strong again!

Yeah, i know beta is a work in progress

I'm also in the beta group, I'm running the E40 map...

What kind of timing targets does the stage 2 93 octane map have?

My requested torque values are much lower than stock anyway. A worse pedal feel is a small price to pay for way better shifting in Alpina D mode. The trans definitely considers pedal position when shifting independent of the actual torque it is requesting.

Does anyone know if changing the top axis last break point for requested torque tables higher than 69.92 will work with MHD?

Shoot me an email @ spencerakimball@gmail.com

I'm also interested in this, as well as a few other things that I'm tweaking in my custom E50 bin - would love to bounce some ideas off of you during the beta testing period to try and get some maps built out... Are you 6AT?

Throttle appears to be pegged at 81 for some reason as well

That's the max angle of the throttle body plate.

Aha! Thought it was a similar value to the JB's throttle percentile

I'm also wanting to test the BMS E85 map. I8A0S AT - still get lots of post-shift flatlining, very excited that it could be fixed but want to see it with my own eyes

Here are the logs of Stage 1 v3

http://www.***********/u/ghaz335i/sta...og=0&data=4-16

From what I have heard, the corrections are worrying?

Excuse the logs, had cars about, so couldn't get a perfect pull.

Just want to leave a small review. Ever since my single turbo install my shift times felt like they doubled (at a minimum). Could not resolve the issue no matter what I tried. Well I tried one of Terry's MHD specific backend flashes today and like magic my shifts are as fast as ever. The checksumming in MHD allows for more tables to be altered and this was the missing piece to the puzzle. The flash went smoothly on my $20 ebay INPA cable. Very nice app!

Found the same results, when I installed my RBs I had tons of shift issues. Since going to the MHD flash using a Wedge/BuraQ tune shifting problems are a thing of the past. I am waiting for good weather for a track night my previous times I believe will easily be eclipsed. Now if only my TFT inlets would get here this week.

Yes the new torque checksums are going to come in most handy for automatic cars running > 20psi at higher RPM. Any automatic trans running a single turbo or even modified twins should use our higher load MHD maps as a starting point. I'll be posting maps with boost/AFR curves for single turbo, single turbo 100% E85, and twin turbo 50% E85. From those three maps customers can modify them as they need in TunerPro.

MHD and I also came up with a nifty way to have special pricing for JB4 users. He's going to program the flash tool to zero out the base duty cycle table when flashing JB4 back end maps. The JB4 ignores the duty cycle and flash only maps require it so it's a nice simple way to differentiate between the two models. Note, BMS is not going to get paid for any of this. We're doing the work to provide you guys flash maps within the MHD environment for free. Just as we did for the BimmerBoost & Cobb environments. With MHD out though we'll definitely be dropping all Cobb support ASAP.

Also note, because we're working for free, we're not going to spend much time discussing the fine details of the maps. We'll make them and post them. And any further discussion or questions about them will be handled on the forum only.

So does this mean purchasing the flasher module ($69) will not be required, and rather a lower cost module will be available for JB4 users?

If this is the case it'd be great if dmacpro91 could get involved with this. Id love to be able to flash using his current app (which i've paid for), with perhaps an in-app purchase to use MHDs flashing code. The we have an all-in-one flashing and logging solution for those of us wishing to use it purely with JB4.
