^^ is it the same E55 that you guys talking ??

Common people, take some responsibility for your actions,
Who knew beating the **** out of my car may break parts.
No offense to the OP, sounds like he gets it, but some of the other user on here are quick to point a finger.

Thanks for the support guys. I have come to the conclusion that it was my fault that my engine blew. I should have not overrevved it so many times. This has happened to me while racing the 2JZ lexus.

chawkins2001

You think it is blown brotha? What was your Rev limiter set at?

mbt53

I'm sorry for you man, guess you're so unlucky ...

iAMGod

Perhaps, but a bit of coincidence no? TCU tunes followed by 2 blown engines, it is a bit concerning.

e500slr

2 blown engines from the same TCU tune in a short period? I agree that does sound a little suspicious.

sorry for your loss man,

How about people raising the rev limiter on stock fuel injectors. That only raises the possibilities of going lean due to the injectors being static.

People really need to stop blaming the TCU upgrade in it's self because they sound like morons.

keith954

^^^^This is the problem, not the TCU tune. It was cold out, and with all those mods he didn't even have bigger injectors let a lone the TTM fuel rail. It sucks and it sounded like he had the injectors and fuel rail waiting for him at TTM.

He needs to remove the heads to see the damage

chawkins2001

I don't think it is the tcu tune. The modded car plus cold temps, no fuel rail and injectors, no data logging device is a deadly combo. Then you throw in bouncing off the limiter ended it all. The tcu tune that allowed the 200rpm increase just insured the damage had incurred, it was not the contributing factor IMO.

loungn14

agreed. But like jerry stated, since his ecu was another company, the redline was set by the other tuner.

It sucks, it really does. This is also the reason why I tell everyone that we talk to to do bruces rail and injectors. Its simply not worth the problems that could happen, expecially with the winter months and temps that we are starting to see...

GT-ER

I've said it before and I'll say it again. With my mods below ( minus injectors ) my stock injectors went static after 5,500rpm...and it was mid 80's low 90's at the time of testing. At lower temps ( 30-40* like some of you are seeing ) I would imagine that by 5,000rpm they would go static and by 6500 you car is freaking LEAN.

what engines are you referring to?

Helli217

A TCU tune on a stock ECU (I only have cooling mods) is not going to have an issue with tranny shifting past fuel cut correct? I guess I don't really understand which control unit is controlling the shift. Does TCU control the shift point solely while the ECU will cut fuel/spark? I am eventually going to do an EC ECU tune, then later rail/injectors/pulley/retune, but I want to make sure my stock ECU won't be cutting fuel before or near shift points with TCU tune installed by itself.
Either way I want stock shift points.

loungn14

right on the money...

yup, its the same car his "friend" is posting about....

you will be fine....

unfortunately this is a fuel related issue.

Johnny....if there is anything we can help you with let us know...

between us and bruce we should be able to find anything for ya....

or just go v12 and call it a day! lol

skratch77

Time outtt.i thougt the tcu raises the shifts to 6800 how does that have anything to to with his ecu tune.

Open her up and if you have bent valves and not a melted piston you over revved the car from the tcu tune.

From tcu tune site





Improvements Include:

- Modification of Torque Management Settings

- Full "M" manual mode and "S" summer mode.

- Reduced Slippage

- Faster Shifting

- Raised RPM Limiter

- Gears hold when in manual mod

- Raised Torque Limiters

Well, I know what my next mod is going to be... *emails Bruce*

you must have missed the other post in this thread by jerry.....

The stock TCU rev limiter is 6600 RPM. His rpm limiter was increased by 200 RPM, which is what I do for all of them. I'm talking TCU, not ECU. I never touched the ECU rev limiter since it was not sent in with the TCU. Other tuners on this forum who tune TCU's use a 250 or 300 RPM increase.

Please keep in mind that when you "bounce" off a rev limiter, you are actually hitting the ECU rev limiter, not the TCU.

I have customers who have had their TCU tuned for over 2 years. I feel it was another fuel issue with Cyl 8.

Enjoy the holidays guys and I'm sorry to hear about this so close to xmas.

I'll be unavailable until next week but feel free to call my cell with any questions!

loungn14

smart man....

skratch77

He is hitting a new rev limiter that went from 6500 to 6800 you even say in your add the tcu raises shift points....How is that not over revving the engine?

IM not talking about when the car bounced off its limiter,im talking about the engine spinning at 6800 rpms.

Look at jimpros videos of after his tcu tune and it looks like his car goes all the way to 7k....sorry to say this but that engine will not last long hitting 7 grand and your tcu tune was NOT around even 4 months ago.

you can search the forum about jerry saying he has tcu stuff and is beta testing it.

2 years ago Jerry wasnt even with Eurocharged and was LET tuning and just about to join up with you guys.

He did not have a tcu tune out and other tuners DONT raise the rev limit on these engines,I dont know who told you that.They wont I asked to get mine done and they said NO WAY.

I cant believe that you dont even bring up that maybe the car revving to 6800 might have caused it to float a few valves.

Here is a stock car with your tcu tune,its going past the stock rev limit and you even say in your add the tcu will raise the rpm limits

http://www.youtube.com/watch?v=Jj9Kb...eature=related

Normal responce from you would be to point fingers to the fueling and not even care that your tcu might have caused this issue.What will you say if johncy has a crap load of bent valves when he opens it up?

The ecu bent em? LOL

320 dreamer

Skratch77 i think ot goes something like this. not gospel mind you just my take on it.
the oem setup is 6200 rpm ecu limit and the trans shifts at 5800 or close to it. new mods raise the ecu to 6500 rpm and the trans mod to 6800 rpm so the trans isnt trying to shift at the same time the ecu is cutting fuel at the rev limit . if the tcu is raised and the ecu isnt then there could be a conflict between the 2 units. i know the tcu and ecu have to work in unison to make the car happy.

skratch77

My car will hit 6500 in M mode and it did that bone stock...It might of been 6400 but it def went up there and would hit the rev limiter if I didnt shift it fast enough.

These videos on youtube show E55s hitting rpms higher than 6500 so it dosnt matter what is the blame,the engine is hitting close to 7k and dont matter if its a combo of the tcu,ecu or any tune on the car.I dont think its SAFE to rev our cars past 6500 rpms and having 500+ ftlbs at that rpm cant be good on some of the highly modded cars.

I never,NEVER take my car past 5k in 3rd on the street and will only do it a few times at the track.

I am pushing my luck and just made 548whp in 3rd gear with stock fueling.My goal was 550 and came close to it.I didnt even bother posting it up but I have cams and that is why my top end is so good.My car peaked hp at like 6200 rpms and is a monster on the street

I am droping the boost down to a 168 or stock pulley and even at stock boost I would not rev my car past the factory limit

sales@eurocharged.com

Where did I say I tuned those TCU's? I have sold a few Kleemann TCU tunes (among others) over the years and I was referring to them.

I started Eurocharged, so the "join up with you guys" comment is wrong as well....

The fact is, our TCU tune is safer than any other currently being offered. Just like other tuners on this forum, we start with OEM software from another AMG model. As with any tune we do, the customer may request what RPM limiter they want to run.

I converted 2 Kleemann TCU tunes this week and I can assure you the RPM limiter was set to 6850 RPM.

I'm sure Jim (Jakpro) will chime in. He requested that his RPM limiter be set at a certain point and I set it.

I'm sorry, but moving the RPM limiter up by 200 RPM's will not cause the engine to float a few valves.

Again, there are 2 RPM limiters. One for the engine and one for the transmission. If his motor over revved, then his RPM limiter was too high in the ECU....

No matter what you guys think you might know, the transmission RPM limiter cannot and will not overide the ECU RPM limiter....period.
