ATI FMU installation on an 02' LS1

**TedsB4Csled** · 06-03-2008, 04:27 AM

Anyone have any instruction, diagrams, good info on installing an ATI FMU on an 02' LS1? I am considering a simple STS Turbo and want a little more fuel management. Also, will this benefit me if not using a turbo? -Or should I install it with forced injection when the time comes? A Walbro pump may eventually follow.
Thanks!

definatly do the feul pump with the turbo install and the meth but these guys have a good intercooler set up for the sts kit. with the sts kit you will want a boost controller because you loose some boost pushing it to the front and also if you do intercooler. I want to do the intercooler because I don't want to have to fill a meth tank all the time. plus the sts kit pushes about 5lbs stock and you can run 8 to 9 without hurting the motor.

How often would the meth tank need to be refilled driving normally? I'd probably use the windshield washer tank.

FMUs are dinosaur technology, why not just run a carb... Seriously though, this is what tuning is for. FMUs are sloppy and inefficient. There is no reason in the world to use one, ESPECIALLY BEING NA. They are just rising rate regulators that are greater than 1:1 against MAP.

Frost is right,

There is no need for the FMU on your car, I have only upgraded the Injectors to 42# and i am fine running on 5psi. You just need a tuner!! Frost could probably tune it.

No FMU for me. Thanks for the info.
