NEW: OpenFlash Tablet for F series M3/4/5/6

[OpenFlash]

Greetings!
We recently purchased our own F10 M5 Competition Package and have been burning the midnight oil. Which means that the OFT for the F series M cars is only a few weeks from public release. Price for the OFT has yet to be determined. But it will include:

-OpenFlash Tablet (v2) handheld
-Free unencrypted off-the-shelf tune files (Stage 1, 2 and 3)
-Free user tuning software with definition files

Custom E-Tuning service will also available for those who want a more vehicle specific calibration.

Official dyno results will start to trickle in next week. Have a great weekend

Sub'd, looking forward to dyno results!

Interested in this. When do you think it will be released?

Saw the prelim numbers for stage 1. I won't spill the beans but people will be very pleased.

edit: just noticed they already posted prelim numbers in another thread

F series M car OFT will be released this month. Just wrapping up OTS map development right now

Thanks! We will be posting official dyno results within the next 7-10 days just before we go public release.

Awesome! I'm very interested in this and will most likely go with your tune. One thing I'd like your opinion on though is what sort of, if any, maintenance would you suggest be done before flashing the tune? And do you suggest changing and gaping the spark plugs before/after flashing?

Thanks

Just standard maintenance will be fine. And of course, we recommend the use of a good quality premium fuel. As for gapping plugs, it’s unnecesary. The only time we have ever run into misfire is when the tune is excessively aggressive and forcing the DME to pull back timing or when boost is too high while running OEM catalysts which will cause excessive backpressure. In both these cases, the fix is a properly calibrated tune, not ignition system tweaks

I totally agree with you on gaping the plugs so I'm happy to hear that answer, as for fuel I've only got access to 91 oct here in Utah so will you be doing an ots 91 tune?

in for results

I'm glad to see that n54 platform development didn't stop after we moved on other platforms.

Anthony and Aditya will also be using this account to post info/support customers from time to time

Any hope for rolling anti-lag? Boost by gear? Cold start delete?

We can perform cold-start delete changes.
We have exposed the "Boost By Gear" tables -- a.k.a. Torque Factor Gradient with Sport Switch (or Sport Plus)



I haven't come across any table for rolling anti-lag in the ECU code.

Sorry what is the 0.00 to 9.00 axis?

Current Gear.

Ahh cool thanks. Seems interesting to me that at 3000rpm it is lower in 1st gear, higher in 2nd and 3rd, then back down in 4th to 7th.

You have free control over all of them from the looks - correct?

One final question sorry, what exactly is the value - it can't be in bar or psi?

We have absolute control over the system. To the experienced eye, this table is setup absolutely perfect (read more below).

It is a Factor. Not BAR or PSI.

Keep in mind 3k is the "sweet spot" where the engine will try to produce a LOT of Torque. Check out our dyno graphs.

In gears 2-3 there is less exhaust energy because the engine accelerates very quickly. The table factor is HIGHER in these gears so that the WGDC controller will know to operate at a higher duty cycle. HIGHER WGDC = MORE Exhaust energy directed to the turbine wheel. This will help the turbo speed up to achieve the appropriate boost targets.

In gears 4-7 there is a more exhaust energy available because the engine accelerates slower. The table factor is LOWER in these gears so that the WGDC controller will know to operate at a LOWER duty cycle. LOWER WGDC = LESS exhaust energy is directed to the turbine wheel. This will help the turbine wheel slow down so that it wont overboost.

Gear 1 - the table is commanding less TQ to control TQ and wheel spin - less TQ = more traction!
Gear 2-3 -- See the description above.
Gear 4-7 -- See the desctiption above.

Fantastic, thanks. Looking at the post I'm linking to below and combining that info, you'd be able to reduce the boost slightly in first (even with 305/30r20 Pilot Sport 4S I don't get grip in first) keep it stock in second, then in 3rd to 7th slightly change the settings to match the torque curve to around 550ftlbs as per your dyno.

https://f10.m5post.com/forums/showthread.php?t=1529275

If one was on Pure Stage 2 turbos I imagine you'd be able to keep at 550ftlbs to about 6500rpm or even 7000rpm? At the moment the torque drops off at about 6100rpm. All on 93 octane only, no meth.

Finally, can you change the sport displays to match what the car is doing? Silly I know....

How long has it taken you to get your tunes?

The auto generation process did not work and searching for my calibration code on the support site provided no results.

I uploaded my original ECU file three days ago and am still waiting.

Needless to say, this is pretty frustrating.
