Mefi tuners

[Mike Norris]

The system itself is not that bad, but it is the actual tuning software and support that is lacking. I tuned Kyle Busch's Camaro for Detroit Speed and it was a SC'd LS engine. It took a while but actually got it pretty good.

So can it be done? Yes. It it worth the time and effort to do it? Debateable for sure. But even before it can be tuned there are a few things to find out.

Do you have the cable and USB security key? Is it already set up for a 2 bar MAP sensor for forced induction? Is it set up and wired in for wide band oxygen sensor(s)? If the answer is no to all of these, then the cost to upgrade to this point plus tuning time may well exceed the cost of going to a GM factory ECU package or any of the aftermarket kits.

Hope this helps.

No usb,it has a 2 bar map,no o2s. Ive had cars with big stuff,fast and this mefi has thrown me for a loop. Thanks for the input,the consensus seems to be to throw the mefi out and go with oem .

Probably a wise choice to ditch the MEFI 4. As others have said, it wont cause your engine to just spontaneously combust when you turn it over, however if there is no one in your area who knows their way around the system, that you would trust to tune the car, then it seems like a no brainer to switch it out. I know most people roll their eyes and groan when they hear I have a MEFI computer.
