Okay im fixing to buy my o2 sensors this weekend and was wondering do i need a rear also with this ecu? Before i was using a jdm ecu and i think they only use the front o2 sensor....(iirc) So does the b14 ser ecu require a rear o2 sensor??? Way i can block it out?

Yep, the B14 requires a rear 02 sensor. I don't know of a way to disable it currently.

You can also look into running an o2 sim instead so you don't have to add a bung to pipe.
So your saying i can sim the front o2 sensor??? instead of swapping it or is that only for the rear?
Does the o2 sensor have any real idleing effects??? I finaly got the fuel pump to work on my car and got it to turn over....but it was idleing bad. I swapped mafs/ re-grounded it, no change.
using ecu talk (during idle)
afm = 1.46v
tps = .048v
acc = 50, then to 75 stuck at 95 for a lil bit, then dropped down...<--is that iacv??
02 = 1.04v
lean/rich reg = 48 bit field
its all stock still havent changed nothing on the ecu you sent me....just popped it in too diagnoise a problem i was having, fixed that and said well i hear you can get it to run with a de ecu and maf so let me give it a shot....its stock bluebird inj 370cc's with the DE b14 maf.
Just adjust your k-factor, the program is currently stock. With the k-factor off you will get wierd idle stuff (it will idle rich or lean). You can tell when your getting it close when it starts to idle better.
dont have the wideband yet, so i dont know.....just trying to get it to run first...then ill futher fine tune it...i think im having a maf problem...i need to check voltages. i have the no rev past 3000 problem.....other than that with maf unhooked the car idles greats sits there and purs...just when you rev it up to like 2500 - 3000 it wants to like die, pop whatever else you wanna call it...becuase of the maf un hooked...im taking it...
another thing when the maf is hooked up its real hard to keep it running...kinda of dies....

Beg/borrow/buy/steal a wideband and adjust your k-value. You can actually ballpark this without a wideband (your stalling problems will go away) to get the car drivable, but you really need to use a wideband and dial it in.
Hey calum, i cant get that lm-1 ne more it was sold....but what about the lc-1 by innovative....it what i can afford right now with things being rough with the family.
It doesn't have a display, but you can use a laptop as a display. If you go that route I think your better off with the Z where you can add a display later. The LM1 is only $100 more if you hunt though, I'd scrimp and save for it. In a pinch you can make the lc-1 work, just a little cumbersome.
Hey calum i got a log from the car using ecutalk.....could you look over it and see how im doing?? I took the car for a spin....builds and hold boost at 7psi....lil poping noise when i let off...but i thinkits cause im running open downpipe...would that also have an affect on my idle....
hey calum i will be sending the ECU to u this week (guaranteed)on the wideband matter i have a AEM windband 02 sensor is it the the LM-1 (innovate) is better ?.
