Patrick. Yes that is an a to b comparison no changes except time for it to learn my setup. About 2 weeks in my weekend cruiser



The EZ system has an adjustable rev limited in the handheld. I can change it from the drivers seat!

I went with the EZ last year - stock chrysler ignition system and it runs great - follow the instructions and you will have no problems - i deviated from the system at the fuel pump / tank setup -

I got a tank and internal pump from rock valley and it's never disappointed - I've had others with external pumps loose pressure for a sec while in a corner with a low tank and I have never hit any issues at all.

Main thing is to install the power leads direct to the battery - as I had the key power off the fuse box and it was too "noisey" for the system to work properly

My madien voyage was a 300 mile trip to ocean city Md car show and 300 miles back - got 16 MPG's with the dual quad setup and driving 75 mph - it also starts instantly with no touching the throttle!!!

I highly recommend it







Very nice tank. I have been wondering what to do to put the EZ efi on my Cuda which has a stock tank that is sumped, and that looks like a very good idea...

I'm about ready to pull the trigger on the EZ-EFI as well. My only concern right now is how does the EZ-EFI handle a cam with a narrow LSA (108 degrees), long duration, and low (8") engine vacuum?




Low manifold vac and high fluctuation can be a problem. This is where systems that let you program the TPS curve as well as MAP curves can help. Mine isn't quite in that low vac range, but I did have to program the light throttle stuff around the TPS more than the MAP for lower RPM and idle characteristics to be good.

I had to set mine to run AlphaN under 1800 RPM to make it behave with a .509 cam. Basically what you are describing.

for a street car its the best option out there - the pump is a warlboro unit that is designed to run at 60-65 psi and that will handle 650 horses - well above what I am running - and it never skips a beat!
