MEFI 4B to AEM Infinity 3 Conversion
Well after fighting the MEFI for long enough , I am going to convert to an AEM Infinity 3 ECM with AEM's kit with plug n play harness .
Time to move forward in Technology! Unless you have the Software from GM , its cumbersome at best tuning the MEFI. The Infinity Tuner is very intuitive and full featured . It offers real time tuning with the option to save or revert . The tables have more resolution where its needed . Also does self learn with 2 Widebands . Looking forward to dynoing this set up , I'll post results. |
Would you be interested in selling you MEFI 4B Computers?
|
for 450 bucks per plug on play harness,,I'd be running a new harness or repin the mefi harness.but hey,let us know how turns out.
|
Are these ECM's supported in a marine application
|
The harness is alittle pricey , but its a time issue , customer wants the boat back to do more mods , or I would have built a harness. All in
I have less than 1600.00 in the ECM and Harness. They are Marine Rated , the molex connector on the ECM is the same style that Seadoo uses on there ECMs. |
I have a mefi 4A ecm I'd sell and those AEM's are not holding up in the marine world.
|
Ever buy this and run it? Does it have provision for gm.flex fuel sensor, still planning my personal 13-1 548s for my boat (E-85)
|
Yes , It works great , the Harness is built by Alexi at boostpower. He uses the AEM ECU on all of his engines.
I have it on a customers 572 , 4.0 whippled engine . Tuning and Data AQ are really solid , its more engineering based and can get alittle complicated. But he has over a 100 hrs on it. Yes it will do Flex fuel. It is used alot on E85 apps. |
