w211 e55 amy low bhp dyno results

Seems you have a great deal of varied advice here, it does seem you are down on power from what you have posted, am sure MSL will get to the bottom of it all, and you will get to enjoy your car again, I hope your problem is very quickly resolved.
My last thing I would mention, is once the blatant issue you have is fixed, don't get too hung up on the numbers, loads of it is, who did what, in what manner on the dyno, the proof will be on track, to a big degree, seen it lots of times, people shout they have this or that, then on track, it's all totally different, get your car fixed, if your up for it, run it at an event, you will soon see where you are, unfortunately I suspect, then it will become a mission as with a good few of us previously, to create more power, expending further big monies, unless you are strong enough to keep your ego in check, best of luck with it all, look forward to meeting up some time.:thumb:

Thanks for the great message. I will see what happens and hopefully make it to an event soon. Seems to be the only true proof of power seeing what times can put down on a track
 
All dyno's vary, id take it back to the 1st place and get it done again. Also did either put it into Dyno mode?

I think they did but i wasn't present for the latest dyno i have a video of it but thats all. Im pretty sure its the ic pump as after driving it a bit on first start up the belt chirp is there but seems to go as the car warms up. The power loss isn't as dramatic as others have described but i haven't had a chance to open it up on a open road yet
 
just seen this post

i know JD and prestige guys very well and surprised if it wasnt done correctly.

every dyno reads different, i havent taken mine on prestiges dyno yet.

take a trip to acid in Brum and see what the readings are. give him a call.

not sure AMD are AMG experts, they are very VAG orientated.

where abouts you based? maybe other E55 owners can be taken out for a spin to compare?

I have faith in JD's skills also that is why I'm so confused whats going on with my car. Its a huge power loss and i can't find any record of an e55k doing it to anyone else, but then again I've not seen a recorded loss from a car running a failed intercooler pump.

After running the car today some pulls didn't feel as savage as they used to but then i felt like the power was back a couple of times.

Im based in thurrock near lakeside i'd be happy to let another e55 owner drive the car and tell me what they think if anyone is local
 
Could I ask to weather you have got to the bottom of the power issue with your E55 car yet?? if so, interested to know what it was..

Once you have the new pump fitted, my personal advice here would be to get the car to a Merc experienced dyno, and get the map re inspected, if its incorrect, you may potentially will be doing untold damage your engine. I am saying this as from the posts within this thread infer a differing opinion from differing parties that seem/may have worked on your car, thats very concerning, in your shoes, and very much more so to me, that those said parties do not seem to be advising you the reason for this power loss, and to which route you should be going. Having paid and had these dynos , these people should be helping and advising you here, not you asking for our help, to which I add, I am sure we are are all happy to give, but those you have paid are surposed to be experts. I am not putting you down here, just passing on my experience from my own 55, if I were nearer to you, I would be happy for you to test my car and me yours, to hopefully assist you, but we are a little away from each other. I hope the pump is the issue, but would re say that may be best to get the map checked again. My own car has a Euro charged ECU map, but I had West Tuning recheck it when my faith in them transpired. As other have said, visit Acid at MSL, he will look after you, loads of M113K knowledge there.
Best of luck with it all,:thumb:

I have had and am getting on going advice from the company that dyno'd the car. I just have learned from experience with these Mercedes that the easiest and most cost effective way to problem solve is to ask a wide range of people.

I just need to understand for my self how a map can go bad before I pump more money into getting something that should not be able to change re done.

I've been on to acid at Msl hopefully he can offer an explanation, will let you know his thoughts.
 
So I fitted the new IC pump over the weekend which I had a few issues with but it's done now. Went for a drive yesterday when it was warm in the afternoon, I am still getting some heat soak but not as bad as it was. Also my gear box seems slow to change down in Sport mode as if my throttle isn't as sensitive as it was.
 
do a gearbox & throttle adaptations reset

Sneaky ECU Reset,
1. Turn the ignition key to the on (not start) position.
2. Press the gas pedal to the floor and hold for five seconds.
3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.
4. Wait at least two minutes for ECU to reset.
The ECU reset procedure only erases the ADAPTIVE transmission & throttle settings. It does not erase any of the fuel/timing or other programming.


then let it will relearn your driving style

How do you know your still getting Heat soak?

I could feel the power die off after a couple of hard pulls it was a hot day though and I was trying to make it do it. After a late evening run today it was pulling good again.

I will give this a try is this the same as disconnecting battery out of interest?
 
Great will do.
Hey Jamie, did you ever discover the reason for the low BHP dyno results? Ive just had my CLS55 dynoed. Stock car, only mod is an x pipe, 116K miles, 13 service stamps, and all I got was 421BHP at the crank. Seems like we have the same issue. Had it remapped and it produced 478 BHP, but this is what it should be making without the map. From your experience, can you help???

Jamie has not been back for over 2 years so I imagine may well not be.

If you are in Staffs, your best bet would be to take it to Acid at MSLP and get it health-checked.

From what I remember when I had my E55K, very few M113Ks produce the quoted or less power - most ran close to 500 standard (mine was 510 standard).

So I can well imagine something is a miss on your one but there are a possible few causes.

Acid knows these cars inside out and quite literally has tested the M113K to destruction himself.

Thanks John. Ive rang Acids mobile, left a text message but Ive had no response. Perhaps he's on hols. I'll try again in the new year.

Quite possible he is away until the New Year.
He will get to the bottom of your issue.
