Do you want the programmable mercury 849 or the new merc digital a13 those are not programmable another option is Brendan power has a new ecu that is coming out shortly and it is a really good one

[MUDSHARK]

I have a 849 that has taken a dump, way too rich, wanted to try the A13. I have no idea why the 849 went south. Going to replace chip with one from Marles but I’m not sure it will clear up my issues. It’s a cheap enough option to try.

849's don't take a chip. You probably have a 11350.

..If you have a DDT,,plug it in and the temp readings should be your local area temps,,,if your temps say 225 your temp sender in ecu is bad,,,it will run rich.Check the M.A.P
sensor reading....base line from merc is 160 on 4 button and 14.6 on otc or merc with cartridge..Your ecu can be repaired if those sensors are bad.

Who can repair the ECU if the sensors are bad?

The 849 still have prom chips

[capteliminator]

My bad, I have 2 of them and didnt know that!

The 849 still have prom chips

.......no...only 11350 ecus have chips....The 849 a6 and a13 are the ecus

that are able to be reprogramed,they still have the M.A.P sensor that can be replaced if bad.......

The 11350's have removable Chips that can be replaced as you and I both know. The 849849 A6 has a PROM (Programmable Read Only Memory) chip (its PROM code is 7119) its manufactured as blank memory then programmed but its potted and cant be removed but can be reprogrammed. The 849849 A 13 doesnt have a Potted PROM Chip. Its a ROM (Read Only memory) and is Programmed during the Manufacturing process and cant be reprogrammed.

Did 2 fattened a6 chips last week

OK,I just opened an A6 ecu and a A13 ecu,they both have a removable chip that you can program...Why would you remove it to { fatten it up},when you can do it via a computer program?
