I got this greddy e-manage off ebay:

do i need a wideband O2 sensor with this emanage? what else do i need? what injectors do i need? I've looked around to try and find out what injectors i need to run my expected power range (300-350 rwhp) but i can't find a solid answer. And i'm kind of confused as to what the e-manage uses to control a/f. as in, does it come with the wideband o2?

basically i've been looking at this website:

http://fc3spro.com/TECH/FM2W/power.htm

and doing everything except the ignition (i've heard more often that the ignition can handle the power-please confirm-), electric fan(it's just simpler to keep stock and it works fine i've heard-please confirm-), fuel pump upgrade (already have FD pump-is it good for this power?) and engine rebuild and porting (already done 15,000 miles ago) up to stage IV+. does this sound like a good way to go?

I don't need a turbo timer due to the turbo being water-cooled also right?

 

rx7ryan - Yes, you will need a Wideband O2. you will not be able to properly tune your car safely without it. I'm not sure what size injectors you should go with, someone else will know that

The way AFR (Air To Fuel Ratio) is controlled is by controlling your injectors. If you want to raise your AFR (leaner), its done by lowering the number on your VE (volumetric efficency) in the table (using the laptop/computer), and the Emanage will cause your injectors to not be open so long, letting less fuel in the engine, getting a higher Air To Fuel Ratio.

From what I understand, the stock igition is good for up to 500 HP.. Someone will correct me if I'm wrong.

Your stock fan should be sufficent, assuming its in good working order. you definately want to test that.

Sounds like you're on top of everything else.

 

so, what's a good wideband to go with for the e-manage? and what injectors? 1000cc/1000cc? hi- lo- impedance? is the FD pump enough to handle the kind of power i'm looking to achieve? I don't need a turbo timer due to the turbo being water-cooled also right?

I think I might have a stage I BNR upgrade. I"m remembering stage II from what the previous owner said and what i thought the receipt said, but i look at the cold side of the turbo and it looks stock a.k.a. lettering on it and a hardline curved around it. does that mean i have a stage I? and can i even reach 350 rwhp with that?

well, i was really trying to find out if i have to get a certain wideband o2 or do i just get a kit (o2 & gauge). and if someone could answer the other questions that would be great. thanks.
