Eurocharged tune review

[eko1]

I had a box tune put on my car in January. Eurocharged had all the info regarding mods done to my car. Everything seemed to be running well. Approximately 3 weeks later I had a check engine light appear that showed that both primary cats were below operating threshold. I had never seen any catalytic codes prior and codes from both banks appeared at the same time. I thought maybe the cats were clogged so I had an exhaust shop cut them out to inspect. They were both melted through as if someone had taken a torch to them. This was especially unfortunate because my state requires emissions. I have shorty headers beacause I wanted to keep my OEM cats. Condition of cats: At this point, I suspected the car may be running rich, so I took it to a shop to put it on a dyno to check afr. As demonstrated in the charts below, the car was running very rich. The lowest sniffer reading is 10 and it was flatlining there indicating it was well below 10. Logging showed the ecu started pulling up to 12 degrees of timing starting at 3000 rpm and adding fuel. First and third runs on eurocharged tune with cat delete: After these runs, another e55 was put on the dyno for tuning after longtubes. The car ran exceptionally well after the mods and reflash. I decided to have this shop tune my car on the spot rather than going back and forth with EC for further tuning and verification time on the dyno. I had already spent enough time, energy, and money on the situation. My car was tuned and within 3 runs it was running much better. New tune (third run) vs Eurocharged tune. The car is and was running properly. It was not heat soaked on any runs, and ait were normal and consistent. All runs were done in 3rd gear. Mods are 168mm, shorty headers, larger heat exchanger, and johnson pump. I have contacted Eurocharged to give them an opportunity to refund me but they do not think it is tune related. They contend that they are not aware of this happening to other cars, setting up fueling is very easy, and it may also be an existing problem with my car. Whether my experience is unique or not, this is what occured. It is my opinion that the tune was not set up right for my car. Overall, I am not satisfied with their product and service.

Well heres a chance to run some 200 cell cats to get the proper power out of those headers...
Been on Eurocharged tune for 1 year, daily drive and beat the **** out of my car and zero issues... havent seen anyone else with this issue either.

How many miles on your car?

I am very happy with my EC tune. I ran my car with stock cats for over 2 years with a EC tune on it without any issues.

[edmond1129]

I have EC tune too, not remotely but I read the stock file and send to Jerry then he send me back the file. The car feel a lot more powerful after tune. I dont have anything to read the AFR, I only have a little problem that the car is vibrating at 2000rpm. I am not sure if it is related to the tune or exhaust mod I have done to the car, other than that the car runs great.

You got a box tune... See bold.

I have been running an EC tune for over a year with stock cats and I have passed inspection twice.

Why are you the only one out of thousands of tunes?

It's ridiculous that you compare box tune with shortys to long tubes with a dyno tune. It's also ridiculous that you would pay for a retune instead of taking a free retune from EC IMO.

Ive burned out primaries on multiple other cars that were stock FYI. I also have contemporaries that have blowtorched out cats to maintain visual inspection.

Are you the first owner? How many miles on the car?

Don't scare me man! I'm about to get an EC tune with my LTH!

Don't be afraid my friend. ALL of the EC gang do GREAT work

From many years of experience in the automobile industry, you burn up cats from running lean not rich. You clog up cats when you run rich, burn oil, or contaminants such as coolant. So blaming EC for their tuning and stating that their "rich" tune caused your cats to burn up is completely false because their tune actually saved your motor.

[Exotic-metal55]

Yes, no way a box tune burnt your cats. Naturally aspirated cars run way, way leaner than that.

[KLR CLS]

2 years running EC tune on a highly modded car running stock cats here. No codes, no issues passing inspection , 1000's of smiles. I highly doubt you blew out cats in 3 week either. Pre-existing condition I would bet.

[nanayaw6]

I have a pair of each of OEM primary cats, secondary cats and manifolds if you need cats all in pristine condition. Will have a thread up after work

Bingo...a ton of bad info here....I'd be curious to see your IATs. From the description it sounds lke your IATs triggered the ECU to dump fuel and pull timing - a common symptom of a bad IC / heat exchanger pump.

[eko1]

While this matter in surely up to interpretation, I believe I received a tune that poorly performed on my car. To summerize:

I had no codes
put EC tune on car
got catalytic codes
cats are melted
dyno shows car dumping fuel
put different tune on car same day without any changes
car runs as it should

I am sure the vast majority of EC tunes perform as expected, otherwise they would not be in business. I feel that for some reason mine was not set up correctly for my car.

In retrospect I should have taken the car and had it tuned on the rollers or verified the remote tune immediately.

[eko1]

On a side note:

Lean conditions equals a hot combustion chamber and cool gasses with no unburnt fuel.

Rich conditions equals a cool combustion chamber and hot gasses as unburnt fuel ignites in the exhaust.

The cat is the hottest part of the exhaust because it combusts unburnt fuel, one of its primary duties.

Also, as stateed, the aits were normal. This is evidenced in the dyno charts as the car did not dump fuel after the new tune was added and made 30hp more.

[RedBullJnky]

You still haven't stated how many miles are on your car, Or the fact that you have "NEW" cats on your car for your new tune. Be honest and state ALL facts, before you try and blame the EC tune. I mean, how come you didn't just have EC retune after you put in the new cats, especially since it is free.

[tbal]

im guess around the 100k miles mark..

[RedBullJnky]

my guess is over 100k

Lol you should have made 40 more with LTs and no primaries

[eko1]

The car has 90K.

It has a test pipe welded in and all runs were done with test pipe.

I have shorty headers. I made the decision to go with this shop's tune because I saw an E55 that was just fitted with LT get retuned. It ran well and I was impressed. I am busy and I wanted to get the car done right that day.

[malahhaor]

How much was it for the shop to retune your car?
EC has free retuned, wouldn't it make sence to ask them to try and correct it first to see if their tune is truly bad? Also why would you get a box tune if you have a modified vehicle?
Even NA engine with just headers will need a retune and if you go anywhere north of that on your mods it's suggested to do a dyno tune.
What type of communications have you had with EC? Can we have more details?
I know my cars aren't anywhere close to the power your pulling but I've had EC done on last 3 cars and all have been fine. S500 had it for almost two years and was at 96k miles when I sold it with 0 issues
Thanks

[ValerSterling]

I am not sure if it is related to the tune or exhaust mod I have done to the car

[cahiil55k]

Maybe you and BenJ got the same pig rich tune.

Perhaps. I'm reflashing tomorrow so we will see if that solves my issues.

OK I just logged my 100% stock car, stock tune yesterday. I wanted to get a ton of stock data prior to modifying. FWIW, the stock tune goes into the 10.x AFR at redline according to my Innovative wideband. Most of the time AFRs are in the low 11s. But from ~5000 onward the AFRs are in the 10s. PM me and I can send you the files.

So to me, it tells me that your base tune was spot on (compared to the factory tune). Could you lean in up a bit and get a few more hp, sure, but do you really want to ? Obviously the AMG engineers wanted the car to run plenty rich above 5000 rpm and probably know why ....I personally would like to keep the tune more like 11.0 - 11.5 area, but the hp difference will be negligible.

It's hard to compare the AFRs from a wideband to a tailpipe sniffer. Sniffers usually read leaner, up to 0.5 bar from what I've seen personally. My stock dynojet pull didn't dip into the 10's until 5750rpm, or ~112mph, in a 3rd gear pull.
