Im tryin to build a LS turbo, wanna run about 12 to 15 out of a T3/T4 whats the best FMU to run either 10:1 or 12:1 what the better chooce

12 to 15 psi is a no go with a FMU. Get yourself some 450c dsm injectors and do some searching in the engine management forum.
Post **** too.

Big tree little rope.

yea you could probly get by on a couple runs every now and then at 12psi with a fmu and walbro 255 pump. but you will not be able to do it everyday you will blow sooner or later

Jesus christ you make me sick. chip ur ecu its cheap as ---- and easy as hell borrow a wideband or get a job and buy one. Read a little FMU is a big no no dumbass.

bitchasscracker

it not cheap. its not easy. you have to practicly be a computer genius to undersatnd the programs used to tune.

www.moates.net (sorry xenocron@$19) $15 chip kit = 1/4 price of fmu

If I can operate it anyone can, it just takes a little messing around with, understanding how to tune willhelp you understand soo much more about you're setup and car. We are sooooo lucky to have these tuning tools available to us its dissapointing that people still use FMU's, AFC's or especially other engine management like e-manage, or aem.

ok and who is going to burn the chip ? desoder your stock chip and resoder the new one the tune it you need a wideband, a laptop, yada yada the list goes on

I'd feel much better just sending the ecu out to xenocron and have it come back running on a basemap. I rock basemaps, and probably always will.

he's obiously got a computer, I tuned my first turbo setup on a desktop by watching my afr's and busting out a calculator You can get a willems for less than $30, hell people throw em away you could prolly get one alot cheeper than that, Borrow a wideband if u have to. damnit that alot of boost to trust a FMU with. Maximize power and longevity of the setup, I dont understand why you wouldnt want to.

If you are going to run an fmu just keep the camera rolling, rape every panty ripper like its ur last, at least you should get a few good pics/vids out of it.
