Hi guys,

Just finished my 55 swap on sunday and had a CEL come on after driving maybe 80 miles.

My car is running is a 2000 running the latest version of ME2.0 (tiptronics, newer cluster, ASP)

I scanned the codes and got the following:
P0170(Fuel Trim Malfunction,Bank1)
PO173(Fuel Trim Malfunction,Bank2)

It also showed that the 02 sensor on bank 2 sensor 2, was stuck reading ~760 with very little fluctuation maybe 10 points.

I changed the MAF and did a reset but the CEL is back.

I am still running the 430 software waiting for a tuner to get back to me. However if this is caused by a malfunctioning part I will need to replace it before I get my tune.

Car is not sputtering or having any issues I can detect.

Thanks for the help guys

That code usually reflects a MAF failure. Since you've already changed that, I don't know. Did you switch it with another used MAF or brand new? Double checked to make sure the plug is fully engaged? Hopefully someone smarter than I can jump in and give you more. I would think it is either sensor related or you've got a vacuum leak post-MAF. Did you swap intake manifolds, throttle, etc.? Any opportunities there? Leave a vacuum line off?

Before the MAF issue becomes super noticeable, it will start causing power reduction at wide open throttle. Maybe give that a try and see if you notice anything. Of course jumping from the 430 to the 55, you might not have the most calibrated butt dyno yet, but it might be worth a shot.

You need to see what your fuel mixture adaptations are at, both at idle and part load. Depending what they are at will tell you what is going on, lean or rich and when. I'm guessing you're not using an MB tester because they don't call it fuel trims.
Look for the obvious air leaks and check fuel pressure...

But one question I have, which injectors are you running? You should be running the ones from your original car if you're running the stock software. If you are running the 55 injectors, that is your problem. This is not an issue with the c43 swaps because those cars use same injectors but your 430 had different injectors. If they are different color, they're different flow.

You can run the 55 injectors if you are tuned for them. Better be tuned on dyno though and you still might have issues because dyno tuning is only good for wot. I'd stick with stock injector, should be enough for the 55, you'll know if its not.

Oh and by the way you're on me 2.8 not 2.0

Hey guys THANKS for all the feedback.

No power loss that I can tell, but I have nothing to compare it to. It pulls very hard all the way to red. But have only done this once as I am stilling running stock software and dont want to be lean.

Hey Benzslo,

Thanks again. I am running the bigger (green) 55 injectors. I am hopefully getting the car tuned next week. Are you sure with regards to the ME2.8 as I dont have the speed option for the cluster?

benzslo

Yes, me 2.8

Make absolutely sure your tuner knows you have the 55 injectors. If they have tuned enough mbs they should have a 55 file ready to go that they can use and not screw around. If they don't.. I'd stick with your stock injectors.

ME2.0 C43/E55 (Green) injector 217cc,

ME2.0/ME2.8 CLK430 (Gray or Orange) injector 199cc,

ME2.8 E55/CLK55 (Beige) injector 283cc

*while you have ME2.8, you can go with (Green) 217cc, or (Beige) 283cc, as optional..

ZAYED,,

benzslo

That isn't correct, my e55 motor was 2.8 and used green injectors. Also my ml55 is 2.8 and has green injectors.
You should only run what the me thinks it has, or else you'll have issues like what the op has, there is no optional unless your tune is changed for them.

I had green 217cc, with my ME2.0, when i went to the dealer to order greens, they said it's replaced with new #, which is beige 283cc,

if you see the last update version of 11/2000 to 12/2002 ME2.8, you will notice its equipped it with beige 283cc instead of old green 217cc ...!@!

ZAYED,,

I am not trying to argue here but I don't believe that for a second. Just because a parts guy says something, don't take it as fact, parts guys screw up, I see it every single day, no exxageration.

If that were true, what if you replaced one injector only, you'd have a severely mismatched set. You guys can think what you want I said what I did.

Sick430, Whats your VIN number?

Clk55 was ME2.0 upto 06/00. I imagine the 430 was also.

Hey Bro

most C43's are on this forum are 98-99 cars fitted with factory GREEN injectors 217cc.
if you wanna play and replace the C43 engine with an M113.980 engine from E55AMG?

Wouldn't it be best to find an E55 engine from the same year the car is?
Say if car is a 98-99 year model, then I should look for an 98-99 E55 donor engine, because this E55 engine already had GREEN 217cc injectors fitted from factory.
Early W210 E55AMG cars shared the same injectors with C43AMG, because of this maybe the C43 ECU software will match and work better with GREEN 217cc injectors because the C43 ECU still might believe the original C43 engine still is in the car?
E55 engine with GREEN injector tricks out the C43 ecu because they share the same GREEN 217cc injectors?

would it be best if I find an E55 engine from a 98- 99 car?
I have found an 2001 engine but this car probably had the ME2.8 with beige 283cc injectors?
should I look for a 98-99 car or should I go for the LAST factory updated E55 engine from a 2001 car and install my C43 GREEN 217cc injectors onto this 2001 engine, this way the C43 ECU will think I'm still using the C43 engine?
what do you think?

Believe what you want to Believe..!,

i'm usually not go to the part guy to ask such ques., i went to the AMG exclusive section, talking to Mr. Oliver Hanord, 21 years MB/AMG Tech. exclusive Manager, he said;

usually MB update every last version of every model, you can see the last version of 92 KE system & 95 LH system & 2002 ME system,

Examples; they replaced injectors in 95 E500 from 197cc to 216cc & 98 S600 injectors from 197.6cc to 218.2cc, also you can see 06 W211 E55, they replace injectors from 397cc to 543cc,

https://mbworld.org/forums/w211-amg/...injectors.html

your MB technician, try that, then dig your experience here,

i didn't tune my ECU yet, i replace the injectors to the beige 283cc, pleased with them, no any issues, car runs great..

Bro,

98 to 2002 5.4l Engines are the same, just little minor things should to be changed, like TB/harness/oil pan/heated hoses,

i put 2002 5.4l Engine in my friend C43, change the harness & TB only, keep 283cc injectors, without tune, his car runs perfectly,,

we are here mixing about C43 & 5.4l Engines, think about it, why MB Engineers increases injectors cc's in the last version of 5.4l Engines,

i can't believe it's by "coincidence"...

what do you think..?

" i put 2002 5.4l Engine in my friend C43, change the harness & TB only, keep 283cc injectors, without tune, his car runs perfectly,,

your friends c43, is it a 98 or 99 car?
does he still use stock C43 ECU without a tune up?
If I buy an 2001 engine, this will not be a problem for me to install in my 1999 C43?

from Kaype's thread i think he said that early E55 had the same injectors like C43 have if i remember correct?
when MB updates a part they have found a solution and improvement for better performance and maybe gasmileage?

cm60k

He got 98 C43, without tuning,

5.4l from CLK55/E55 will fit perfectly, but you have to change oil pan if you get 5.4l from ML55/S55,

Good point Dennis, we discuss about injectors in Fabian's thread, early C43/E55 sharing the same greens injectors,

As you mentioned; definitely MB increasing cc's for a reason, also why MB still using same injector cc in CLK430/E430 till 2002..?,

that means MB Engineers knows that 5.4l should to have more fueling cc/ha, isn't..?

ZAYED,,

KJI3jflarryfe93

technicians replaced the injectors for 5.4L because engine needs more fuel spray for better performance and fun with the heavy right foot, step on pedal to the metal

i found an 2001 w210 engine with 150000KM this is one of the last and best engines i believe?
now i only have to get the dineros to buy the engine.

cm60k

Good Explanation bro., you may right..,,

personally; i prefer Engines from late 5.4L models..

ZAYED,,

KJI3jflarryfe93

i personally think the last years of a model cycle is the best years when cars recieved improved updates, these cars/engines must be stronger than earlier models

So new development. I had a failed MAF at home that I installed to see what would happen with the codes. After clearing the current codes I installed the MAF a got a P0100 right away. I did not get the P0170 & P0173 even after driving for a while (50 miles). After going back to the good MAF I got the P0170 & P0173 after clearing the old codes and driving for 30 miles. Codes were cleared with handheld and battery disconnect.
