C32 FUEL INJECTOR UPGRADE
Hi, wanting to upgrade fuel injectors to 550cc, most aftermarket one's need some sort of modification I think, but I read somewhere that the sl500,g55,ml430 flow at 550cc pn a1130780249, can someone please be kind enough to advise me if this is correct and also if they will drop straight in the c32, thanks and safe motoring sickooli. ps or if anyone knows an aftermarket product which can plug and play.

I can tell you what I'm running. Bosch 0280158117
You can search ebay for 0280158117. They are Bosch EV14 550cc 48mm injector. I got mine from Eurocharged. Also search for these: LS2 LS3 LS7 EV6 Engine wire Harness to LS1 LS6 LT1 EV1 Injector Adapters . Will make install much easier.

Don't buy used a1130780249 injectors. New ones will cost you $$$.

Bosch 0280156304
I use these Bosch 0280156304 (A1130780123), they are a Mercedes drop in and show to flow 542.3CC per minute on the Weiss chart, though I don't have any track times to see how well they do.

Perhaps you don't need a tune for Bosch 0280156304 (A1130780123). I ran it without a tune. They are standard OEM replacements for 2006 E55 and are also listed in EPC as replacements for the C32 injectors. They are rated at 542CC but at 55PSI while other flow numbers are shown at lower PSI. Bosch 0280158117 flow 575CC at C32 standard fuel rail pressure of 58PSI. Either choice is fine, depending on the price.

It's little weird to me Lenin, (396cc vs 542cc) is high jumped without tuning..?!?,
i think MB replace (072 to 304), to let you bring the car to them to reprogramming the ECU to the latest updated version of AFR..!
what do you think..?
ZAYED,,

For my current Bosch 0280158117 injectors I did get a tune from EC and recommend that it should be done by everyone that is going with larger injectors.

You must have a tune if you change your injector size significantly. The ecu can only accommodate to a small degree and only in closed loop mode, NOT open loop ie WOT. If the car runs without a tune it will foul plugs, ruin cats, be slower and less economical. A tune will adjust the load maps, duty cycles and prevent those things.

Comparing at 3bars it is 400cc stock vs 480cc for the 2006 injectors,
after testing some cars the mercedes updated the injectors without updating the ecu afr,
my brother has cls55 p30 which has the 304 injectors from factory, i test it myself on the dyno, i watched the afr on dyno stock ecu with the 304 injectors then i flashed with the 2003 ecu, the afr remain the same no change, don't ask me how![nix](https://mbworld.org/forums/images/smilies/nixweiss.gif)
but with the 2003 software it get back like 25 hp it went from 510-515 crank to like 490hp but the afr has remain the same, maybe cause the p30 file has more hp from factory.
