Anyone have any experience with cutler efi? Found a fair deal on 2 systems, but can't find any software or really any info on the ecm. Could I adapt a mefi 4 ecm to the harness?

cutler I believe was bought out by holley a couple of years ago

More than a couple, from what I understand Arizona speed bought them and then Holley did

read this story that I written it is 4 pages long and has a lot of info about the Hirel / Cutler EFI

I just bought one and it came with a manual.. I may be able to take it apart and scan it for you if you'd like....


Interesting... The pictures in your article are of a Cutler system I just purchased.. LOL

I have one with a flashed mefi and rc injectors rail mounted reg . Batch fire , off the shelf gm iac map ect tps ect.all the money is in the throttle body ecu .i think what sets it appart from your ram jet or 525 efi set ups it just looks cool . The early manifold mounted ecus crapped out and just looked wrong . But its the only game in town where you can throw a holley and a 7psi pump in a box on the boat and get home if something goes bad (intake mounted ecu takes a dump) beyond that prob a toss up between that and the usual asm bbc fuelie conversion.have another intake and set 46lbhr injectors batch fire harness no tb ecm or rails on ebay has been met with crickets ..

So the cutler ecm is self tuning only? I'd rather have some control and set it up how I want it

A Quote from the manual....

"The ECM tunes by seeking out the peak torque an engine can produce at a given load point. After every new point is tuned the ECM uses this new point as well all other previously saved points to build a fuel map optimized for the engine"

The Cutler setup was a first back in the day. It was finicky at best on the tuning. At times you had to fool the computer into getting the tune to work properly. No one would give up the software to talk to it. I have several ECU's sitting in a box, some known good, some known bad and some just, in the box.. If you get a good deal on the manifolds and hardware, you could go to a different ecu to control them. I use Megasquirt on my motor and it is easy to tune compared to the Cutler.
Hope that helps.

What cfm are the throttle bodies?
