I was wonder if anyone has had a problem with hitting the rev limiter after having a tcu tune. Not realy sure if its the rev limiter or torque limiter. Right before every shift under wot trottle the car almost pauses before shifting. I have s/c pulley, and ecu tune.

I have it and I was hoping someone on this forum would have it fixed by now so the same could be done to my car.

AMG3.2

Yes, this also happens to me and a few other members on the forums.

I was told by Eurocharged that I was hitting a torque limiter. It would be good if they could give more info on this, but so far that's all I know.

I'm not sure if there is a fix for it so I just usually shift before 6.5k to avoid hitting this limiter.

Yeah, just call them up and get a reflash, they can get rid of the torque limiter. Happens more often when it's cold.

AMG3.2

My torque limiters weren't removed, they were just lifted up a bit. I don't think they remove them completely.

Im assuming that going back to the stock shift points would eliminate this problem or is the torque limiters being raised the cause of problem. I would hate to lose the raised shift points for no reason its just driving me crazy like it is.

AMG3.2

I have no clue, you would have to talk to Eurocharged about it.

if your not datalogging you should be. the delay has much more going on

AMG3.2

320 Dreamer, wouldn't Eurocharged have already figured something out if this was a problem? I know your suggestion is only trying to help but I mean we bought a product, and now we have to do R&D to figure out if it's beneficial?

This doesn't sound right...

Flame suit on just in case.

This problem is the only reason I am hesitant about getting the tcu tune. I want faster shifts but not if it means creating problems.

Could someone please explain what the torque limiter is?

Justsaymo01

I'm calling them today about sending it back and getting the shift points put back to stock settings. I'm confused because if its the torque limiter and it wasn't a problem before at the stock settings and now that it's raised it is, what's the advantage. I'll keep you'll updated!

Eurocharged was very willing to work with me to solve this issue back 3 weeks ago when notified them of the problem. I just have been too busy to work on this which will involve:

1. getting the remote ECU cable and reflashing the ECU to lower power output at the 2-3 shift and maybe other points.

2. if that does not work then the TCU will need to be sent back.

AMG3.2

So I called Eurocharged today and I asked them about the pause in between shifts. I was informed that a few others were also having this same problem and that a C32 was going to go in for further testing. Adam said for me to give them a call back to see if they have fixed the problem which might actually be in the ECU.

I really like the TCU tune and I'm hoping I don't have to go back to stock.

Hopefully, they get the TCU and ECU sorted out with regards to AFR readings.

I am going to dyno my car Tuesday and get AFR readings with my current versions of the ECU and TCU software. Hopefully, I get a good AFR throughout the rev band.

I will for sure post them up by Tuesday night so everyone can see. I am also curious as to compare my WHP with that of Eurocharged's graph on their Dyno Dynamics. I will be on a Mustang dyno so it should be some what similar.

My TCU is with Jerry right now. I asked to have the TCU matched to my Stage 2 ECU tune done last October. I also told him I am willing to reflash my ECU if needed to provide a better setup. I will report back what he recommends. I'm sure they are looking at all variables. I'm in no rush with the snowfall this week.

Please keep us posted on any developments. It is great you guys are sorting this out so hopefully those of us who have to ship our tcu around the world don't have to go through the same problems. The stock 1.5 second shifts are very underwhelming.

AMG3.2

Well I've talked to a few people and I've decided that a dyno run would be pointless. I'm going to give eurocharged a call back on Wednesday since they told me to give them a ring and ill see what they have come up with.

Edit: I found this over at the Crossfire forums. Looks they one of the guys over there is having the problem as well.

Gave Eurocharged a call back today and they still haven't gotten the C32 in for testing due to rain. I was told to call back Thursday or Friday when they would most likely have it figured out. I'm pretty stoked to have an answer since I've been told to take it easy on the car until they come up with something. It's seriously boring to drive the car until 3K RPM's...

C32maximus

I just heard from Jerry. The updated program has been loaded onto my TCU and is waiting for testing. Sounds good to me. I just ordered two new 615K's for my rear to test it out properly.

I really hope the problem gets resolved as I also experience the same thing. I don't drive my car much so it hasn't bothered me too much. Do your 265s rub at all? I contemplated getting 265s but went with 255s instead.

Justsaymo01

They just recieved my tcu today im not sure exactly whats going to be done to it but I mentioned to them about going back to the original shift points or ajusting the torque limiters. I havent ran my car car at the track yet since all of my upgrades, but knowing my car is going to hit the rev limiter between shifts isnt going to give me a very good e.t. If for some reason they cant figure it out im going to have buy another factory tcu. Yea, it bugs me that bad!

inflectionpt

I gotta think Eurocharged can at least restore the TCU to stock settings. I'd be very surprised if they can't.

C32maximus

My 265s are mounted on 18X9 +35 with 1 deg of neg camber with the plastic tabs shaved down. They do not rub. However my new wheels will be 18X9.5 +35 which will stick out 6mm more and will probably rub. Nothing a little fender rolling won't fix. After having 19" and 20" on the car nothing beats the handling and traction off the line of a good quality 18" tire.

AMG3.2

Nice, can't wait until mine is fixed!

Well its the Air to Fuel ratio that I'm worried about lol not ET. But, you shouldn't have to buy a new TCU. They can flash the TCU back to stock. This is my plan if the new version doesn't work. I'm crossing my finger though because I really like controlling the gears.

Justsaymo01

Ok maybe I was jumping the gun a little on maybe having to buy another tcu. I need to just give them a chance to resolve the problem.

AMG3.2

+1 They should be able to do it.
