Dennis,

I put 5.4l from W210, and run C43 ECU, without any tune, it runs great, i raced many 55's with good luck>>thankss god..,

Fabian is right, it's an optional for ECU fuel remap, but it's NOT necessary to do it, while you have ME2.0 with W5 shifter,

swapping an Engine is a good choice, if you want to go with ME2.8, you will have to get donor CLK55 to switch everything,,

lot lot lot of job>>>need relax>>OMG..

When i installed Injectors from late 5.4l model, better start & more more acce. response..

I'm getting confused here what to do if I should stick with c43 software after doing the engine swap or send the ecu to a tuner for E55 software update?


here's a youtube video.
If you click on Show more info + read the comments in this link you can see some people say, car will go worse and lose power with an E55 flash and the recommendation is to stick with C43 software this way ecu will adapt to engine?

Stock ECU

E55 software mapping = car lost some HP/TQ

seems like keeping the C43 software without remapping to E55 software is the best solution according to both youtube videos information.

I heard many complaints with 55 remap from good experience guys,

in my case; i didn't tune my car yet, but definitely im soo pleased with the results with stock C43 ECU,,

that may concern with tuner touch it self, need very good tuner to deal with it..

how is your fuel consumption with stock C43 software if you drive in normal conditions VS if you drive like a shaitan on the road with your heavy right foot on the axxelerator?

fuel tank is 62 litres. with normal driving conditions, do you get cheap gas mileage?
How far do you go on 62 litres of fuel with legal driving?

I asume E55 engine will drink more fuel because the c43 software is not correct for this engine?
How far do you go on 62 litres of fuel when driving like a car thief?

i wouldn't let an incompetent tuner touch my ecy if i had it reflashed, they would probably fukk up everything?!

hmn ... at least, i never made such a modification with the original ecu so everyhing is theory but:

When you use the 4.3L Engine with its injectors the ME opens the valves for around 2-3ms. when you switch the engine to 5.5L and also install the larger injectors it should be no difference for the ME ... the ME only measures the time it opens the valves, not the output of the valve itself.

So, after a little brainstorming, i would say: yes, you can go with your original C43 software. maybe not optimal and the best way would be to get hands on a original C55 Software ... but it should work without problems as long as you use the correct infjectors for the 5.5L ME2.0 Engine! ME2.8 Engines uses different injectors, dont know if they are compatible.

greetings.

what you're saying is that year 2001 engines get updated ME2.8 and different injectors compared to say year 1999 E55 engine with ME2.0 electronics and old style injectors?

when i find an engine at the junkyard, they are complete with injectors

kaype

jep ...

ME2.0 4.3L
ME2.0 5.5L
ME2.8 4.3L
ME2.8 5.5L

all have different injectors...

KJI3jflarryfe93

i will look for a 1999 non-tiptronic car, perhaps this engine will suit better for my car as it uses older version injectors

thanks for your help

kaype

Everything before 07/2000 is fine and has ME2.0

greetings, Fabian

Yeah.!, it's eating fuel a lot>>lot, i'm also using 98 RON fuel, thats helps to eat more i believe..,

honestly; i didn't compare normal VS hard conditions for fuel consumption, not that care about it.,,

with old injectors, i'm always facing faulty O2 sensors, but after replace them to newer version, NO more O2 sensors in the ECU memory..

ZAYED,,

KJI3jflarryfe93

brotha, you live in UAE, gas is cheap there, where i live gas is expensive.
i always use 95 octane as it's cheaper.
do you ever drive in normal conditions or is it always flat out 100%, do you see the gas-needle drop fast in normal conditions?

how far of distance KM do you get on full tank 62 litres with normal driving conditions?

thanks

Dude ... a AMG is not supposed to save fuel...

My E430 took around 13.5L/100km, after the switch to E55 it took around 15.5L/100km (both 95 Octane) and now with the supercharged engine i am at 18.5L/100km but with 102 Octane Fuel...

Nothing comes from nothing ... if you want to save fuel you´ll need to take a C200 Diesel

cm60k

Dennis,

I agree with Fabian about saving fuel, most guys know they will save some $$$ in their wallet for fuel, little more fuel with correct ECU/ROM map = more power..,,

i didn't count anything about fuel consumption, that's one of my bad habit..

ZAYED,,

KJI3jflarryfe93

you misunderstood me about gas consumption, reason i asked about gas mileage is because if i install an e55 engine it will work with the wrong ecu from c43 amg.
113.944 engine for c43 amg paired with correct c43 ecu gives correct gas consumption.
113.980 engine from e55 amg paired with wrong ecu from c43 amg, what will gas consumption be like= will gas consumption increase to an abnormal use of gas or will it be the same or similar like when i had the stock c43 engine?

you are absolutely right, if you wanna save gas an AMG is the wrong car for ya!

I have the final question for engines fitted with ME2.8/EGS52 electronics.
would an E55AMG engine from 09/2001 work in my 1999 c43 amg if I removed the wire harness, ME2.0/EGS51 and throttle body from my c43 engine and fit these parts to to this E55 AMG engine from 09/2001 with ME2.8/EGS52 electronics?
Meaning I will be swapping parts between engines to fit my c43amg?

kaype

The engine would use more gas, as i said in my posting above the ME opens the injectors for the time X ... 4.3L injectors have less fuel output the the 5.5L injectors so the 4.3ME will open the injectors the same time but more fuel will pass the injector. So you´ll have more fuel consumption of course, but not because of the 4.3ME.

Yes, you can take the 09/2001 Engine and use your old harness and TB, anything else should be plug ´n play.

greetings, Fabian

great news about this: Yes, you can take the 09/2001 Engine and use your old harness and TB, anything else should be plug ´n play.

would it be any good idea to swap injectors from my c43 engine and put them on the E55 engine instead, the ME2.0 ecu might read the data more accurate and give correct fuel spray from injectors?

thanks

As i remember; 98-99 E55 uses the same injectors with C43, (which is Green color),,

but MB replace them in all M113 5.4l from 00 to 2006 with bigger injectors, (which is Beige/Yellow color)..

ZAYED,,

KJI3jflarryfe93

then i can put my c43 injectors into the 2001 E55 engine, put the c43 wireloom, the c43 throttlebody, then it's only a plug n fit into the car.
after installing the engine i have to let the engine adapt to c43 ecu when i drive my car.
is it that simple to make the engine swap and make it work correct?

cm60k

Exactly, as you described, swap the E55 Engine only, everything else will be from your Exist C43..

i would recommend to keep the injectors from the E55 engine!

our friend Zayed says 98-99 E55 have the same green injectors like c43
newer version injectors are of course better with more high flow for gasoline.

maybe the older version E55 injectors might give a more accurate spray with ME2.0 from C43 ecu?

cm60k

That's may related to the Engine displacement, 4.2l>>5.4l, ECU could reads more fuel RON before & after, then save it to the data/file memory,

but not soo sure about that, just a THEORY..!!

ZAYED,,

kaype

just checked part Numbers.

C43 (M113.944) and E55 (M113.980) Engines with ME2.0 HAVE the same Injectors.

But changing Injecors on the N/A M113 is no big deal so i would say ... if you can find a ME2.8 5.5L Engine go with that injectors, if it wont work well, switch to the C43 Injectors. I really cant say what the ME2.0 makes of it ... the only ME2.0 i ever had was in my old E430 and i am happy that i have switched to ME2.8 and then to ME2.8.1
