I understand a wideband lambda is used to measure air/fual ratio but does it replace one of the current lambdas or as well as the other two?

Depends - If ist just for a A/F Gauge, then you need to retain the stock o2 sensors for the ECU.

 

If its for a Standalone ECU management system that runs a Wideband o2 setup, then it replaces the stock o2 sensors.

So for eg i have a stock ecu, i would have to buy a a/f gauge and would that wire directly into the stock lambda? or would i get a seperate wideband with it and fit that as well as keeping my original lambdas?

You need to get a seperate wideband sensor, and fit it, while keeping your stock sensors.

Aaah i see:bow:

The AEM wideband sensor with gauge i bought set me back £180 and came with a pre-tapped hole that you have to drill and weld onto the manifold

I got an Innovate LC-1 which seems to work nicely with Nistune. This comes with a boss to weld to your exhaust at your preferred location. I just install it in the stock LHS location when I'm messing about with fuel maps and take it out when I'm done. You can leave it in but they're quite an expensive thing to wear out without good reason. They lose their calibration every few months too and need to be removed to 'free air' calibrate again if they're going to be accurate. The LC-1 can also emulate a narrowband O2 if you want to use it as a stock O2 sensor - bit beyond me though...

How much did you pay for the nistune ecu and would you recomend it?

I would 100% recommend it, 110% if you're gradually tuning your car and don't want to pay out every time you make a change for someone to burn a chip for you.

 

Price was $200 for the daughterboard, $200 for a single user software license, $110 for consult cable + few $ for shipping - Note this is Aus $. Me and Rich666 got a board each and share a software license and consult cable so it's prob cost us about £200 each. Support is excellent and the software is awesome for diagnostics etc. Of course to get the best from it you need a wideband sensor as well unless you're going to pay a tuner to map it on a rolling road (recommended for best results).

 

Cheers

Thanks for the info, ive just been looking it up on thier website. ive already got a consult cable so all i would need is a wideband, software and the daughterboard? so is this like a mapable piggy back type ecu? or a full stand alone?

It's a daughterboard that replaces the original ECU chip (you need to socket it), not sure if it's a piggyback, as that implies to me that the original chip is still in place. There's a 4 pin ribbon cable you also need to solder into the mainboard but it's really easy if you have a desoldering tool and a decent iron with a fine tip. You put the ECU back in the footwell where it came from and all programming is then done via the consult connector.

Assuming the consult cable you have is the same you'd need a daughterboard, a software license and a wideband (if you want to map it yourself).

This is what i have too..... :bow: :bow:

Have you got a stand alone jimmy or is your wideband just to keep an eye on things?

just to keep an eye on things. Eventually i will have a standalone.

There are more Custom managements out there than just Nistune and AEM :)

i have seen tried and tested Megasquirt and Megajolt (not on the 300zx) which are both fully programmable and customisable ECU. Far cheaper to buy and operate :)

 

And uber easy to use and are compatible with Narrowband and Wideband 02 Sensors too :
