Don't make it complicated. Do your settings, flash your map. Done.

So do I have to get a custom tune or can I just run a mhd backend tune with my jb4 and be good to go with xhp stage 3? Will I get all the benefits of xhp I don't understand i see alot of old posts saying it didnt work well but there has been updates since then I didn't know if the issues have been sorted out im not interested in getting a custom tune.

You are reading about the flash process and people not sticking to what the app tells them, right before flash: Disconnect JB4 before flashing.

Besides that, you can use xHP with JB4 just like everyone else.

I run jb4 with mhd backend and xhp stage 3. Not an issue

Done!

It looked somewhat complicated for me cos i didn't expect it would be that simple. ...thx anyway.

Can anyone recommend a setting/intensity level for the throttle blip?

I left most of them as is, but changed my 2->1 to -25% and my 3->2 to -10% to remove the lurch I was getting on the blip in the lower gears especially 2->1

Best is to try for yourself. There are people with Stage 3 that turn it up all the way and then they are others that back down certain shifts.

With the Stages 1,2,3 we set a baseline for many things in the transmission, but the custom features allow to further tailor each Stage to your personal likings, within a certain range.

The next app release will feature even more of that!

Based on the analysis below One may appreciate high revving cars and in general the importance of transmission, gear ratios etc.
The analysis is a reasonable representation and explains the basics but obviously has assumptions.
1. No traction loss
2. Gear ratios used are 6spd auto from 2007 e92
3. Redline 7k, and no ecu nannies like torque limit
4. Shape of curve below will vary based on your tune etc.
5. No drag (altho drag will only make the higher gears worse)
and few more im sure

Graph below shows acc on yaxis and rpm on x. The shape of the curve which mirrors the torque curve will depend on your car. I have shown dashed lines to demonstrate if the torque falls off at a faster rate after 6k.

Well i think the graph shows it, riding on 1st acceleration is the highest, you can go 6500rpm+ on 1st and still have higher acc than anwhere in 2nd! notice this shift point advances forward (meaning shift rpm keeps dropping as can clearly be seen by the arrows) as you move UP thru the gears since the acceleration in the next gear keeps getting closer. Make sense?
Also notice the dashed lines - if your torque falls off quicker obviously the shift rpm reduces as can be seen clearly.
Something missing in this whole graph? HP.
Sgop335

Thanks for the detailed info and graphing it. I think I understand the concept.

For a dummy like me, can I have a dumbed down answer?

I have custom tunes with stage 2+ hardware + inlets and have 1 93 octane map and one e60 map on and E90 n54 xdrive auto car.

For power levels in this range, what would the optimal shift points be (for the drag strip) for each upshift?

Maybe 5,800 RPM's? Maybe a bit higher for the 1 --> 2 shift?

Thanks!

For those that have put some miles on D MODE in both stage 2 and stage 3, what are your impressions?

Subjectively is there a noticeable difference. S and M mode impressions are well documented, but I haven't seen as much feedback specific to D mode in each of these stages.

Dumbed down answer would still depend on how the torque curve (aka acceleration) drops with rpm. Clearly not all torque curves are the same!
A log for each would answer that.
I can run virtual dynojet and demonstrate.

I guess D mode in both is about the same.
I do notice for my transmission that Stage 2 feels better than Stage 3 in D mode.

I found S to be to harsh in Stage 3. It did quite a bit of lurching. Didn't like it. I am now back to stage 2.

For M mode, Stage 3 transforms the car. I loved the Stage 3 manual mode, but the other modes for Stage 3 made it unusable as a daily driver for me.

I haven't bought the option that allows changing the shift points. That's on my to do list. I am looking forward for a min RPM in gear function so that the car won'd downshift and have me cruising at 1200-1500 RPM. I drove a manual for lots of years and I like creating with the RPMs higher so I don't need to downshift for every maneuver. I know gas mileage will suffer. I can live with that.

I experienced the same lurching in stage 3 until I had a transmission service done. The fluid change and adaptation reset really helped. Shifts are smooth and crisp now. In all stages.

What does the transmission service consist of? How did you reset the transmission adaptation?

Depends on your mileage. Usually fluid change every 40k miles, then second time around, you'd want to change the transmission filter pan and the bolts. I'm unsure about resetting adaptation.

xHP automatically resets its adaptation after first long process of flashing. Then it won't do it with any update to follow (unless instructed). The app has the option to reset adaption manually though.

Try resetting throttle adaptation in MHD first.

Sgop335 I hear you. Here are a bunch of 1/4 mile runs from the last time I was at the track. Can you please give me some recommendations, based on these?

Obviously I don't need each run analyzed - just figured I'd share all the data I have available.

Thank you!

2 runs: https://datazap.me/u/mfish123/55-deg...e-14-mile-runs
3 runs: https://datazap.me/u/mfish123/55-deg...3-14-mile-runs

techwiz Thanks for the feedback. I'm looking forward to more customization options.

I actually paid a bit more to get a custom map but I was heavily involved. Basically I took the backed up Alpina map from my car and loaded it in turnerpro. I then drove around a bazillion times closely monitoring accelerator pedal position and shifting behavior under different situations, in each gear and changed the D mode shift map until I got it how I liked it. it was a lot of driving, testing, logging, tweaking in tunerpro, flashing the new revision, rinse repeat. It was quite tedious. You can control both upshifts and downshifts in every gear.

I'm the same as you in that I prefer a slightly higher shift point (not the WOT max shift point) in every day driving. I then sent this map to Xhp, paid the fee and they incorporated my D mode shiftmap into the tweaks they did 2 stage 2. Money well spent.

I would imagine they could give you a hybrid of stage 2 D and S modes with stage 3 m mode fairly easily.

With my limited knowledge I couldn't quite get the 6 --> 5 downshift how I wanted it and just based on my impressions they were able to tweak for me.

So maybe all my self tweaking was overkill and you could describe what you're looking for and then can make it a reality based on your description.

Gotcha! Not that I ever reset anything, I thought it did initially after flashing xHP.

Some good data there, useful for the community! Results are shown below and I think it speaks for itself. Acceleration is in arbitrary units (but all relative). As can be seen, 1st gear shows highest acceleration up to approx. 6000rpm. It tapers quite strong at 6500rpm. Black arrow show shift RPM to maintain highest acceleration.
It appears a shift point of 6100 rpm suits well for at least the first 4 gears.
