hey guys i got a Greddy E-manage for christmas ... but i a lil worried that i wouldn't feel any difference because the engine has very little tunable parts ..... Has anyone run this Piggy Back EMS on stock injectors ?....

is this the emanage "blue"?
i just installed the emanage ultimate, on my 5sfte. to control larger injectors with the turbo.
on a stock 5s, you wont really be able to gain much from it.
no real need to control the injectors, the ecu does a decent job in stock form.

yeah the blue one , u said that u have 460cc injectors from a Rx-7 .. did u have to make any changes to ur plugs on ur injector connections ? Cuz i have the e-manage already so i need to put it to use .... can i get ur advice on that

what exactly are you trying to do with it? whats your goal? it looks like you have a stock 3sgte swap. they already have 440cc injectors in them. the ones presure2 uses would not work in the 3s.

OK really my goal right now is to find out wat i need to use the E-Manage

Cuz i got the e-manage for christmas

lagos meant by "what is your goal" was "what kind of hp range you're aiming"

well you can use it to piddle around with the timing some, lean out the high throttle fuel as its probably too rich stock, data log the engine, get a wideband O2 and you can datalog with that and play with the timing and fuel maps on the PC and see how they do in the car.

you wont see much with a stock engine, get some FI, nitrous, or atleast some boltons like intake, header, exhaust.

My Hp aim is bout 300............i am also goin to be adding a exhaust and downpipe ... also i am goin to try get some injectors , wat size i don't kno yet

im going to assume you have a 3sgte from what you have posted.
if that is the case,
your not going to hit 300whp on the stock turbo, no matter what you do fuel wise.
the stock injectors are good for ~270whp, as long as they and the rest of your fuel system is in good working order.
the DP and exhaust and intake on a jdm ecu will net you ~235+whp @ ~15-16psi
to gain much above that, your going to have to upgrade your turbo, and to get above 300whp your fueling will need to be upgraded, as well as your ems, because @~270+(IIRC i think its actually lower than that)or so whp, the AFM resolution is maxed out anyway.

read this... it will tell you what you need to do, to get to where you want to be
