Eurochaged
I have an appointment in April, getting mine tuned on the dyno, hope it's worth it, couldn't pass up the opportunity.

Or could you give me any info if you've done this and what the results were? I'm already paid up for the Minneapolis dyno tune in April. Thanks.
Sending my ecu this Monday. Had to do it since they charged me $300.00 which is great.

Some people have done it and then posted about how the car "felt" faster but I don't believe stuff like that. I mean, how many of us here can reset our TCU and make the car feel way faster and more alive until it re-learns our driving style again. Nothing will lie to you like the butt dyno.
I would expect speed43's custom air box and elbow would deliver better results for the money.

My problem right now is I can't get the plugs from the ecu off. I took off the top clips, but when I pull up they won't come out. I emailed Zayed and asked if I have to pull the plugs up real hard or if they slide to the side than up. Don't want to force it up just in case they slide somehow. There's no room to slide actually so has to be pulled up. Just want to be sure before forcing the plugs wires up real hard.

I have my TB that I can port and send that to you. Or you can send me yours, up to you. I also have the elbow and maf housing already so all I need is the TB. $145.00 with your TB and shipping costs, I now ship with FedEx ground because I've had bad experience with usps. pm or email if you want to proceed. Thanks.
I dont necessarily doubt that the tune might net gains over the larger airbox and porting, but the only reason i think that is because they can adjust the tune to run off of 93 octane. the car is setup to run 91, but 91 is not available almost anywhere in the states, so we all run 93 without being tuned properly for it. outside of that im not sure where much gains can be had, but im no expert, but i just know some HP cain definitely be gained from 91-93 octane if tuned properly.
i plan to have my CLK55 on a dyno to test power this season, then maybe late in the season i get a dyno tune as well and really get some good results.
any more details on eurocharged group buys or dyno tune specials? i see you mentioned one in april?

I'll post results and yes there will be before and after. I have some light modifications besides the 5.4 so it might not be typical gains for mail order tune on a stock 5.4 swap but in the ballpark I'm sure.

Turned out that my ecu has two T25 bolts, one on each side. You can't get to them unless you remove a small Phillip screw on the right side of the plastic bracket. This screw holds the whole bracket of the ecu and that other ESP box. Both will not raise up unless this little screws is removed. Once I did that I was able to raise the whole thing up and had access to the T25 bolts. Once those were removed the ecu came out.
Of course this was after I removed the connectors and some other wires that prevented the whole bracket to come up to have access to the T25 bolts. Just called eurocharged and they said my ecu is on the table waiting tune. A gtr is ahead of me at the moment. So maybe tomorrow I MIGHT get it or for sure Friday. They did tell me if they get the ecu by 12pm they will ship same day. My ecu was delivered 10:42 Am. So hopefully tomorrow.




i don't have those two T25 bolts on mine..!,
looks like U.S model is differ than Euro or Japan, or depend of the spec. of the car..!!
Thanks for sharing..

It was very simple once I did it. Before touching it I was so lost. Every forum kept instructing to pull up the ecu. And I was like why is mine so hard! Sometimes you can only read and ask around than you have to use your own brain and figure things out. Glad I had your help and PjMack or my brain would not have succeeded on it's own.
Car ran great before but it's real great now. It was a bit lean at baseline, 13.7:1
is it harmful in the long run to use the stock c43 ECU with 5.4L swap, meaning slowly killing cats with a lean fuel mixture?
cats will eventually fail when they get worn and old or clogged/poisoned from poor fuel quality, however will c43 ECU/5.4L swap help cats die a premature death running stock c43 ECU?
you are an MB tech, do you know if this is a possible issue?
how much is a Eurocharged custom tune?

13.7 is a bit lean but not enough to hurt cats. What will really kill them is way too rich. I've seen cats glowing red from being way too rich. Rich might mean a cool combustion but doesn't mean cool cats, the fuel continues to burn. It was $800 for me.
most people run their stock c43 ECU with 5.4L engine swap, they never bothered to tamper the ECU because a custom tune up costs from $500 - 800 bucks which is expensive.
people decided saving money???
main thing is that if doing the 5.4L engine swap, cats won't get screwed up running stock c43 ECU.
people can enjoy their rides for many years ahead with this engine modification without worrying about anything
