WTF-DYNO RESULTS AFTER 55 INSTALL

DYNO PULL WAS ON A MUSTANG DYNO - FRONT ROLLERS WERE DRIVEN OFF OF REAR ROLLERS- HAD TO ROLLED INTO 3RD GEAR SO MAX TORQUE IS LIKELY MISTAKENLY DOWN-did not see the car in person the engine came from, visually it had the amg tags on intake-im hoping its just the dyno , but their are some shady beaches out there. not ruling that out yet.
ANYWAYS 225MAX HP
241 MAX TORQUE-AFR WAS LEAN MAX 15.3 TO LOW OF 13.6 AVG 14.8-
ECU IS GOING OUT FOR A TUNE

IVE SEEN POSTING IN WHICH THOSE WHO HAVE DONE THE SWAP ARE SHOWING GOOD BASELINE NUMBERS- ????? DYNO IS BEING USED AND DOES ANYBODY HAVE ANY REAL UNMANIPULTAED DYNO RUNS BEFORE AND AFTER

PLEASE EMAIL ME YOUR THOUGHTS AND ADVICE

Should to see the E-prom map of the ECU, it may not relearn the new out-put of the Engine power,,

Is the dyno reads correctly, some dynos didn't gives a correct reading of frequencies,

its happened to me with "2" bad unofficial daynos.....

there should be no badge on the intake of the 55's, or 43's for that matter. if there is a badge, someone put it on there as a phony and i'd be even more skeptical.

if you can get the engine number or part # off the block, that would be what you need. let me know the number and i can look it up for you.

i've had a dyno give me blatantly false reults before, to the point i thought there was something wrong with my car... over 100 hp down and dropping each pull. but it was infact the dyno... the car was as rock solid as ever.

the difference to the 55 motor is huge, you should be able to tell by driving the car easily if it's a 55 or a 43.

Swap

Engine checks out 113986 on block
It's extremely lean- gotta get it in the air and checks e brake drums, dyno guy wrapped the straps around the rear control arms and pulled on the ebrake cable in the process , noted smell and figured it out- hoping nothing is seizing inside pulling my power down!

A dyno (engine or chassis) is a truth sayer and heart breaker for most....I have used every kind on the planet as a tuner and instructor and the secret is repeatability. A Mustang is a good dyno...but is "stingy" on numbers compared to the long time industry standard in chassis dynos...a Dynojet 248c. If there are repeated variations in the testing method (cell temp, airflow, operator technique, software setup, etc.) that negates the effectiveness of the unit as a testing or tuning tool.

Is the Mustang unit you are using an AWD version? I didn't understand the comment about the front rollers and rear rollers....if it has both, it is an AWD unit and setup is completely different than for a 2WD. Automatic cars should be dynoed in the 1-1 gear.....3rd for a 4 speed box, etc. The trick is getting it to the correct RPM to keep it from trying to kick down a gear when you start the pull.

Your A/F is obviously a source of concern...but remember that factory calibrations err on the side of emissions and leaner is cleaner. Sweet spot for an N/A engine is 12.7 or so....and on a boosted application it depends on fuel system and amount of manifold pressure....but mid 11's is not bad to start.

Good luck...and if you have specific questions, shoot them at me and I will try to help!

500E Signal Rot
On my friends C43, after the 5.4l swap, it dyno'd at 284.72 rwhp and 309.89 torque. Thinking he could gain more power, he had a performance ECU tune done. It was suppose to be a E55 tune. After the tune and some driving time, he went back on the dyno and noticed a power drop to 280.22 rwhp and 292.50 torque. The AF after the tune, went from 14 to 12.

Based on the experiences, I wouldn't recommend any type of tune to the C43 ECU.

As for the power drop, I don't know what to say, but your numbers represent a 4.3l motor, not a 5.4l motor.

Dyno

Yes the dyno was an AWD set up- Ecu is going to dynocomp for tuning, I'm going to rerun the dyno at the same spot just got comparison then take it to another location That has the dyno jet .
Agreed the mustang was very stingy, the car feels much better than the c43 engine, but not 100%
Anxious to see the change with Ecu tune

I assume your Engine pulled from "W215 CL55",

is the Injectors green with OEM #: "113 078 01 49", Bosch #: "0280 155 839".....??

Saw a YouTube video where a dude did a before and after with his C55/43. The C43 stock ecu fetched better numbers than the E55 tune.

Stingy or conservative would mean 20-30 RWHP less on a 550 RWHP car in my world....on a Mustang as compared to a Dynojet.

When I had my swap done I had this issue until I changed my maf. Low dyno #'s and ran extremely lean. Changed the maf and the car became an entirely different beast. A/f 's became beautiful.

is there any difference between MAF's for C43 and E55 cars?
i assume you bought a new MAF designed for e55 engine?

your car was running lean with c43 maf fitted to e55 engine?

The mafs for all the V8 m113 motors,4.3,5.0,5.5 are all the same. When the maf goes bad these are some of the usual symptoms.

my bad, i thought there were different version maf's for each m113 AMG engine.
i had mine changed maybe 6 years ago.

maf's don't last long do they?
should they be changed on regular basis maybe every 5 years or so, just to be on the safe side avoiding lean fuel mixture?
I don't have CEL safety feature on my euro C43 only US spec. cars had the CEL.

my car runs strong and its the same maf I put in back in 2k5.
I guess for maintenance purposes it would be a good thing. I will perhaps change mine soon .

I would say that if the MAF is not causing any concerns nor code errors, don't change it, but that's just my personal opinion....
