575 SCi ECM tune
Does anyone know who tunes the 575 anymore? Obviously ASM isn't an option due to the myriad of bad experiences. Does anyone know of a software that allows the user to tune?

Stock tunes should not be an issue, but if your talking about on the boat, then there is MEFIburn and a couple here on OSO maybe

I have a few 575 tunes on an old computer. What exactly are you trying to do?

I can only assume the PO did not tune the ECU when he added the small pulley and SuperChiller. I think this because It seems to still have a lot of the same manners others say these have in stock form. So, I suppose the standard ECM re-flash with the Boost kit would probalby suffice. Rev limit a little higher would be nice. Can you use MEFI Burn with these then, Snap? |

Any luck unlocking your ECU? I have the same issues. Running the blower and TBI setup on my 454s, need to adjust fuel trim.

I would have the ecms tested - the injectors drivers are known to have issues and cause rich to very rich conditions also what are your map sensor readings ? what are your fuel pressure readings ? what are your coolant temp readings ?
Let me know if I can help with the ecm side and a scan report |
BUP- I havnt actually run mine yet almost done building, probably a couple weeks out. I have decent size roller cams and everyone I have talked to said they are rich from the factory. I replaced all sensors and performed a ring out of the harnesses, not worried about that. My intention was to buy MEFI burn to tune, then I stumbled upon the fact merc locked the ecm. I am looking for the code to unlock, have someone unlock it or get a generic canned tune I can start with. I don’t mind purchasing the tune and unlock but I would require the ecm to remain unlocked so i can finish tuning with a wide band.
