Possible ecu upgrade?

[tdcoats]

I have a 1995 ranger with a 95 model 175 hp mercury black max xri efi. The ecu is bad and it id the last analog style. Does anyone know if i can upgrade to a digital ecu which supposedly started in 1996. I dont know if the gauges and harness are compatible and or if anything else will need upgraded as well? Thank you

You may want to have this moved to the Merc forum, this is a rather specific question about a Merc and you might get quicker and better answers there.

Thank you. I was wondering that but this site is difficult to navigate/operate from a phone

Best news ive had in a while thank you very much... idk how to hook up to or read the computers... can u by chance tell me what the tps needs to be set at or what all i need to ensure with the tps itself

send me an email address (pm if ya prefer) and i'll send ya a pdf file that has your motor in it.... it will have information, instructions on tha tps for most Merc/Mariner V6 motors....

tdcoats@yahoo..... you the man.. i put a new stator, trigger plate, voltage regulators, fuel pump to find out the ecu is also bad and 1 year from being rebuildable..

sent.. be aware of tha ecu "fixes".. its a very tricky deal.. even tha so called big name "fixers" can't get it right a lot of tha time.. it really depends on "whats broke inside"... jmo

I see.. i appriciate that. Im going to try and find an ecu from a good engine. A digital one if possible

Just buy a new one from Brucato and avoid someones else's problem. I would not buy a used ECU unless the seller would stand behind it or I could send it off to be checked before shellin out the $$$$

That seems like a really fair price backed by so much supporting evidence
