ECM Recalibration
I am looking for someone who will recalibrate a merc ECM. I bought a used one...correct part, but wrong calibration. It is an MEFI3. Dan

OK...I added headers last year and have been told I sould re-program the ECU. I don't want to be running too lean.

Is anything done to help bump the top end at all?

i am told you can certainly tweak the calibration. the issue is getting it right. btw is it ecu or ecm?

ECU: Engine Control Unit
ECM: Engine Control Module
->no difference, just to the liking of the manufacturer

You can get the ECU to push stock motors some more, but will have to run premium fuel. Weigh the cost vs. gains. Give mark a call, no harm in asking.

His pricing was quite reasonable, stayed in phone contact and was prompt. So, from a very pleased customer I highly recommend Mark, at Precision Marine (504) 469-7463
for any ECM recal or related issues. Dan
