That is a very good idea. Running a Cobb Stage 2+ on my car initially set at ST (stock throttle mapping) mode. When I switched over to the linear map it was much easier to modulate throttle in D and find where downshifts hit etc.

Still do not prefer D by any means, it is more bearable that way. Mostly use Sport and Manual modes, unless HWY cruising or warming up.

As far as you know would these values also work with Cobb, right?

Also, correct me if I'm wrong but the Requested Torque % (Low) corresponds with D mode and therefore the values you posted should go in this table right? (My understanding is that requested torque % (high) is for S mode)

here are my actual torque request maps (3):



does anyone know what are the differences between them (high vs low vs driver ) ??

Now we're talking!

Anyone have a good throttle map for the Alpina flash with a Cobb?

I don't have a Cobb but if people can confirm that it can make the D mode better in Alpina, I will buy it ASAP.

Are the tables you posted just the unmodified OFT maps provided by Shiv or did you modify these to help with the shortcomings of Alpina D mode?

According to the Cobb tuning guide, "On non M, IS, or manual vehicles(anything without an M, D/S or sport button) only Requested Torque - High is used. Requested Torque Low is active any time the M/Sport or DS is active.

Thanks for clarifying. I probably should have checked the tuning guide first. Looks like for my application (an automatic 335i) requested torque high is D mode and requested torque low is DS and manual mode.

@ls3c6 Are you using the same values in your requested torque (low) table as you are in the (high) table? If they are different please post the (low) table too if you wouldn't mind. I noticed that, at least with Cobb, if you change the scaling in either the low or high table it changes the scaling in both tables and makes the scaling of the columns match.

My concern is that if the DS / manual mode table has the same values as the D mode that the throttle might be too touchy in DS / manual mode. Either way I'll try it with both tables matching but if you've already discover ed what works best for both tables, it would help me get this ironed out more quickly without trying to re invent the wheel. Thanks in advance!

I'm going to put them in both high/low, but I drive in D 99.9% of the time so I only have in high for now... it makes alpina good to me

I'm having the same problem where it shows the car on a lift after flashing the 7603527. The Alpina flash and 7601494 flashes fine but the 7601494's shifts in M and S are way slower than the Alpina flash. I never knew how fast and hard the Alpina flash shifted until I flashed the 1494

I don't remember how the OEM flash feels like but the 1494 definitely seems to feel the same if not worse than the OEM flash.

I am so sick of the drive mode from the Alpina flash... Makes the car sound like it has a CVT.

@steve.kodra, did you find a solution to the problem?

@ls3c6 and @steve.kodra I just tried these values in the torque request (high) table with Cobb. Big improvement to D mode!

Its much more eager to down shift. Also, as long as you keep your foot on the gas a little bit while trying to accelerate moderately it will upshift much higher than 1500 RPMs and you don't have to feel like you're trying to force it to hold gears. In other words the upshift points are natural for the rate of acceleration and power you are requesting with the gas pedal.

I really like how fast the shifts happen even in D mode. None of those slow, laggy, wishy wash shifts where you feel the pause in acceleration with the other trans flashes. And depsite the speed of the shifts there actually less perceptible than the other flashes - very smooth.

The only small thing I don't still like that probably can't be cured with throttle mapping is being in 6th gear at 40 mph. We kind of get that dead zone when we're cruising between 40 and 50 mph and then want to accelerate when we're already in 6th. But now if you give a little intentional stab (not rolling into) to the gas pedal I can most of the time get a nice predictable downshift to 5th gear. Worst case if it doesn't downshift at least we have fast spooling turbos with lots of low end torque and can get moving in 6th gear even at such low RPMs.

I can confirm that this has fixed the laggy D mode with the Alpina flash.

Steve also suggested changing the driver requested torque table in addition to the high/low %, I have not tried it:

Code:
Requested Torque (Driver)								
	0.00	3.00	10.01	14.99	30.00	50.00	80.00	100.00
0	0.0	5.5	16.5	27.5	44.0	66.0	88.0	100.0
10	0.0	4.4	9.3	16.5	27.5	55.0	88.0	100.0
30	0.0	1.7	4.4	8.8	16.5	38.5	88.0	100.0
50	0.0	1.1	4.2	6.6	13.2	33.0	77.0	100.0
62	0.0	1.1	3.5	5.5	12.1	29.7	66.0	100.0
93	0.0	0.6	2.6	4.4	11.0	26.4	66.0	100.0
124	0.0	0.6	2.2	3.8	8.8	24.2	66.0	100.0
155	0.0	0.6	2.0	3.3	7.7	22.0	66.0	100.0
try it guys, I'm tired of flashing... let me know if it makes things any better yet

can anyone share a good IJE0S bin for 08 335xi/6at/dci/93oc otherwise stock?

What exactly is driver requested torque?

The throttle vs requested torque solution makes sense. I read that the TCU uses throttle position to determine its shift points rather than requested torque. It's basically making the trans think that we are under more load than we are.

Slick.

Cant wait to try it.

Maybe the stock Alpina B3 ECU has different requested torque mapping thus making it more drivable?

I'll try this today and report back if I can know the following:

Is the speed (y axis) on this table kph or mph? I'm thinking kph but just want to be sure before I edit it in ATR.

Also, I see the y axis for speed is scaled differently than the default values - is that intentional?

Thanks for the feedback. Being that you're in Europe and being that the first 4 rows (0, 10, 30, and 50) look unaltered and match the modified table, I'm pretty darn sure its in kph.

Can you show us your "low" map too ?

I 've flashed Steve Kodra Torque request %(high) map, Alpina B3 "D mode" behaviour is better, but still not what I'm expecting.
It's still upshifting too fast in my opinion.

Maybe I should go further with this high map, or do you think I should mod the driver map too, as sugested by Steve to LS3C6 ??

I don't believe we will ever get the Alpina to act like the 1494 in normal driving conditions. The trick with increasing the "Requested Torque %" tables is going to be our best bet. You are not going to hurt anything by giving it a try. I have done this change on many cars already. IF...the pedal is a bit too touchy for you with the tables listed in previous posts, change the x-axis values as shown below.

I had to revert to stock values until I can figure out why these values cause limp mode / torque limit malfunction at part throttle, see my thread

I've tried with this request torque % (driver) map, but no improvment.
I'll try today with higher values on request torque % (high).
