A shame. Is it because of the older transmission?
I thought it was supposed to increase shift speeds to be similar with an smg trans.

My car is 7/2006 and xHP works just fine on Stg 2... the only thing I could go on without is the rev matching feature which I have found silly... and also displaying what gear you are in D mode is a bit distracting, for me it would make more sense in S only (and Man of course).
Besides this it works flawlessly, very happy with the overall behavior...

I made some very minor tweaks to the shift speed settings, but more or less default OTS. Last shift isnt as crisp because I had to ease off while hitting the paddle after someone switched lanes in front of me

Would def recommend doing a fluid change if you're over 100k. The flash changes a few things, I personally wasnt comfortable until i was sure everything in there was in good shape with fresh fluid.
FCP euro sells the kit ready. also...I hope you fixed your o2 sensors from that old post before modding your car more

hahah wassup bro!! yeah my bimmer down rn! I fixed the o2 sensors & installed a new water pump & thermostat & added some inlets while it's down!

But...like everyone else said. Replace the seals while you are in there. More pressure + worn/cracked seals = more problems .

sorry to bug but do you know exactly what would need to be changed? just flush the fluid & change gaskets?

I'm running the stage 3....I hate the rev match. It's pointless, and keep me of dangerous when it traffic and the car automatically wants to blip the throttle on downshifts.

I was thinking about going to stage 2 just to get rid of that.....but it sounds like stage 2 does it also.

Wish xHP would put at option in the app to turn that rev matching on and off.

Change the fluid, put a new pan/filter on, and replace the 4 sleeve seals and 1 double D seals under the valve body. Changing out the shift solenoids isn't a bad idea either......wish I would have done mine, I need to replace mine.

I'm familiar with your huge thread here and on SS. I also recall someone likening it to a CVT, but if those crisp shifts are the behaviour you're seeing with Sutphin, it honestly seems closer to DCT

yes it has torque reduction built in, it pulls timing and will shut throttle if necessary to hit torque targets between gears. my logs show roughly -20 degrees of timing pulled between gears when running xhp.

if you target say 550nm torque actual on the log, during the shift it can drop down to 200-250nm actual

nothing in the xhp tune can be 'tweaked' to change that, the only settings you can change that xhp has in the custom module would technically make it worse but supposedly shift faster(not my experience), with the torque reduction tables. xhp says pulling more power between shifts will shift quicker.

[iqraceworks]

I thought I could feel the power being reduced right before/after shifts.......guess it wasn't just in my mind.

Any way to force the DME to keep the throttle open and not pull timing between shifts? Custom tune?

You can now adjust the throttle blip by percentage in the latest version. Makes a world of a difference, no more herky jerky coming to a stop.

This can be adjusted to an extent with the Torque reduction setting under the custom module,

Lowering Torque reduction can increase load on the clutches, as more torque has to be maintained between shifts.

I'd be interested to know what the Sutphin tune does in this regard. Unfortunately mine is 01/07 so no Sutphin tunes available.

Running XHP stage 3 with custom module. Can't see any downsides and I've had it well over a year. Did the oil, filter, pan and Mechatronic Sleeves.

You are right. You can adjust it. And none of it will improve anything. It either pulls MORE power or SLOWS the shifts more depending on which way you adjust. It's junk.

As far as mine. It holds full torque and timing through the shift 1-4 and pulls 3 degrees for the 4-5 due to the small weak clutch on that gear

Not all of his tunes will do that. It will depend on your power level or custom tune request. My car is almost stock so it gets away with it.

Drive isn't meant to shift fast, its meant to be smooth. Sports and Manual mode does shift faster,

Depends on a large extent to the condition of your clutches, Sleeves and Solenoids though.

Nice! I will have to give that a try. Do I just have to reload the stage3 flash to have this new option ?

Lol I wouldn't call it junk just because it pulls timing, I'd rather it pull timing then reduce the life expectancy of the clutches.

If I recall correctly too much torque is what kills the automatic transmissions.

My car isn't stock, its Stage 1 at the moment and I intend to go Stage 1+ which should pull about 600nm.

The ZF6 is a good transmission but whatever you do its not a DCT

Can you post a video with a Vbox/Draggy to show a comparison of 0-60 or 100-200k times with Sutphin tune vs Stage 3 flash?

I posted a large thread. All the information you want is in there. Including dragy and logs.

Nothing on my tune is reducing life, I'd be much more concerned with wear on how xhp shifts than how mine does now. Xhp is violent, mine is just smooth.

If anything was going to break with this tune. It would be my car. 170k miles and never been serviced. I'm quite sure this fluid is soot black.

Also worth noting. If you don't want to run this tune, don't. I have no need to sell you the tune. I'm telling you it'll make your car better. If you don't want it to be better or like the way it is. Leave it alone, doesn't make a difference to me.

Mines similar, shifts quicker on WOT than part throttle.

Yes, the new interface is wayyy different. All the options are in the bottom right-hand corner. Basically xHP has integrated the custom map in the new version at no additional charge.

Ok I'll see if I can find your thread

Never serviced 170k???

Face-palm,

Boggles the mind how someone who hasn't serviced his car is talking about custom TCU tunes.

Haha! I like to feel the shifts, I don't like slush boxes.

According to the website, Sutphin tune needs that "Jink" XHP to work, lol

It's not that I don't want to run the Sutphin tune, I can't because his website clearly states he cannot tune pre 03/07 cars.

On a serious note, no need to be a hater or a fanatic.

You feel the shift, it just doesn't feel like garbage.

Yes, 170k no service. Itll get it this year. Also on original turbos that are nearly dead. Needs a bit of work, bought for cheap a year and 30k miles ago. Since been totaled and fixed. Runs mid 11s almost stock, works for me.

You have to update your TCU to the newer version, then you can run the Sutphin tune or the newest XHP update. From people who post on here, it sounds like it costs a few hundred dollars and coding with ista/inpa.

Well it was probably your car then, mine doesn't feel like garbage.

You mean replace the TCU itself?

I'd rather spend the money on intercooler and downpipes, plus RBT-Tuning already confirmed V3 maps are being developed for the older pre 3/07 TCU

Then there you go no upgrade needed and you get to 'feel the shifts'. Win win.

And yes you replace the trans computer with the newer version then you can flash the newer 'larger' files. Which is apparently the issue. The old cars use one that has half the capacity. At least what I understand. I have an 09 haven't dealt with it myself.

Guess it's an even better case for sutphin seeing as how his tune was able to fix what is clearly a mechanical issue with a tune while making it faster. Damn.

I might consider the TCU and Sutphin tune, after the FBO upgrades, depends how long I keep the car.

To be honest, I couldn't care less if my car is 0.2 secs slower than another, its not a drag car. I got the car because of its tunability and the fact that I like straight six engines and its fun.

If I wanted a drag car, I wouldn't have got a rear wheel drive car.
