Thanks!

I know that you normally drive around in "M" mode, but if you could also do a few pulls in "S" to show how the TCU runs in that mode also, that would be really helpful.

On my car "M" mode is so sluggish and lazy between shifts that I gave up using it almost immediately... I don't know how guys can crack off fast shifts with it in an E55. I hear the E63 is MUCH better in manual mode than our cars.

thats weird my car is like that in s mode,Ill tell it to shift and it keeps pulling for like 2 seconds and then shifts when it feels like it.M mode is 5x better

GregMB

My "M" mode acts just like you described your "S" mode.....

I call for the upshift.....then wait.....wait.....wait......then after a couple of seconds (and quite a few extra RPMs) the transmission finally upshifts. You almost have to anticipate the upshift and ask for it about 500RPMs sooner than you actually want it just to get the timing right.

It was a real disappointment. I couldn't figure out why guys even cared about upgrading to the fancier E63 paddles on the steering wheel, because the shifts were so lousy that I wouldn't ever want to use them.

Weird.

Hey J, if you get a chance can you shoot a vid with the trans in drive and make a half throttle from 0 to 65 so that we can the trans shift by itself. thx

I drive in M mode because there isn't that delay between shifts in S mode. M mode is far more responsive especially with the TCU.

Johncy2000

Will do bro! After lunch I will post another vid.

Does it rev-match on the downshifts?

Johncy2000

No it does not rev match upon downshifting. I wish it did though. lol That would just be awesome.

Interesting you say that because if I drive in M mode and hit the button to shift the car doesn't actually shift for several hundred rpms after I hit the button. Like at the track I would want to shift around 6300rpms so I would hit the button before even getting to 6000rpms, it sucks how slow the transmission is. Faster times were had with it in S mode.

Johncy2000

The delay between pressing the botton and shifting has greatly been reduced.

Hammer Down

That part IS cool but the important factor here is.... has the shift times in "S" mode been increased? Its well known that at the track "S" mode is quicker than "M"

What was the cost for the flash?
Also, did you have to send in both the TCU and ECU together?
Thanks for sharing the vid, your 55 does sounds sweet.

I would like to know as well.. does the shift feel stronger in S mode?

Also. how was removal / installation of TCU?

Is it hard to get to / remove?

What was turn aroung from EC?

I have been very tempted, but always seem to have at least one mod on the burner..

urbamworm

The flash is $650 which only the TCU is sent to them.

loungn14

they have....

no need to send both ecu and tcu. If you have a tune from another tuner, you can send your ecu to remove the torque limitors though. Makes a big difference.

Yes, S is stronger. DO IT...its awesome.

http://www.eurocharged.com/C32_TCU_R...structions.pdf *(same as e55) Will take about 5-10 mins to do.

We tune it and send it back the same day we get it. Ie next day it to us on monday, we get it /tune it/ send it back on tuesday next day for reinstall wed.

Johncy2000

Thanks loungn14 for the TCU flash you Eurocharged guys are elite!

Johncy2000

For those wanting to remove the TCU:
1. Remove Passenger floor mat.
2. Pull back on the carpet where the foot normally sits.
3. Remove black foam cover
4. Remove two 10mm nuts and pull the metal frame which holds the TCU out.
5. Unhook TCU (Black box that says Siemens on it) It has two connectors connected to it.
6. Remove two 8mm nuts holding the TCU.
7. Ship to Jerry.
8. Receive TCU in mail and do the reverse.
9. Enjoy your newly woken up beast!!

God, that music is awful.

Here some driving music.

Very relaxing music! I like Wiz Khalifa though. He is legit right now.

Your car sounds brutal, and sure pulls hard!

Johncy2000

Thank you very much! I tried all kinds of different exhaust configuration until I found the right one. I am 110% satisfied with it right now.

GT-ER

Yeah, every time I try M mode I hit the rev limiter a little bit. It's a BILLION times better than my G35's auto tranny was in manual mode but it still kinda sucks.

Johncy2000

Ya its no DSG but its pretty fast!

GregMB

Is there a writeup somewhere on your website that describes this mod in more detail?

I'm having a hard time differentiating some of these terms, and which ones are included in different tuning packages you offer.

TCU tune creates a stronger (Harder) shift and higher shift point. Think "B&M Shift Kit" This is done on the TCU which is sent to EC (Picture provided in thread)

A compliment to the TCU tune is to increase your rev limiter to allow shifting to take place later in the power band and removes torque management. This is accomplished with an ECU tune. EC can do the complete ECU tune, or if you have a tune already that you are happy with, they can modify the file to change only the RPM, torque management.


I hope that helps. Two different tunes that go together like PB and J
