[Mk2] [Turbo] Which wideband do i need?

[RyanRs]

I am looking at getting a wideband controller, i need one that will interface with my LinkPlus G3 EMS and have a AFR gauge for the dash.

When i look on google, i see so many different W/band systems and the majority look like they are just a sensor and a gauge. I see AEM do a control box for ems integration but they dont seem to come with a Gauge!!

Can anybody advise what i need! and which manufacture is best.

Thanks

Hey Ryan, i'm using the AEM on mine http://www.aemelectronics.com/wideband- ... -gauge-25/

There's an output signal to allow you to feed your ems Ticks your boxes!

[Jim Galbally]

all of them will come with a controller of some description, you cant get a gauge to read direct off a sensor. most have analog outputs that can output wither a wide or narrowband signal

ive personally used the innovate stuff before with success but didnt find the controllers very realiable, kept breaking them!

i have done alot of research into wideband controllers and guages, i got recomended to go with the PLX systems in california there are super piece of tech as there new digi guage can be daisy chained to all of there devices i one guage can give you up to 8 read outs at once, and as its digital you can download and style of guage or back round colour etc and also have an aux output and input so you can relay it to your aftermarket ecu and do away with the old crappy inacurate narrowband sensor, they also have a new range called the ob11 guage wich plugs directly into your aftermarket ecu to display all paramiters, theres so much they can do i would be here all night exsplaining, they have also won countless awards irl post you the you the link buddy

these deffantly come out on top imo

they also can ship from greace if you ask so it saves the inport tax

hope this helps buddy i was impressed with them i went and bought sum goodys off them the next day

Aem Uego is the best i have used for in-car installations

what about the new analog one?
maybe a reason why the digi one is getting cheaper?

[jimGTS]

ryan if you want to get these aems from the states, give me a shout, as i may have one to and we could go 50/50 on delivery + import duties...

[RyanRs]

cheers for the info everyone. Im thinking the AEM is going to be my best option. Jimbo, how much is it from the states? that looks like quite a good price on that link that ryan put up... £165

but if it is considerably cheaper from the states then i could go 1/2's on the shipping / import...



Must ask quickly tho... IF that is the price for a wideband kit thats linkable to an EMS & datalogger and has a gauge, then how comes the AEM controller box (no gauge) is dearer? what does it do that the gauge kit cant??

i just thort i would throw this in the equation, i dont no if you running power fc or not ryan or anyone else but im pritty sure the apexi power fc cant run wideband as the tech is dated and also no aux inputs/outputs etc can anyone else confirm this

[Jim Galbally]

you dont really need a wideband input on any ECUs. some ECUs have an easytune featyure for making basemapping similar but hardly any will use wideband inputs for the actual running. they'll still accept a narrowband input for closed loop fueling tho

[GTS GAV]

its just i have always been told by speacialists its much better to run an wideband 02 sensor to your ecu instead of the stock narrowband sensor as the narrow band isnt presise or accurate enough for tunning high hp turbocharged cars as this vid exsplained that the diffrence between 12.2 and 12.5 afr measuments can be up to 20% power loss

whoever told you that didnt really know what they were talking about mate

what he probably MEANT to say is that a narrowband sensor is only good for detecting if the car is running rich, lean , or stoich. and so is only any good for idle and cruise conditions.

therefore it is impossible to map a car with the readings from thes sensors

however 90% of aftermaret ECUs and 99% of stock ECUs will only use a narrowband O2 sensor input for closed loop fuel control under cruise conditions.

plugging a wideband input into most ECUs will do little more than enable the extra display in the ECU mapping software, the sensor will not be used for closed loop operation.

also most of these wideband controllers arent particularly reliable and most professional mapping companies would reccomend you use a normal narrowband O2 sensor for closed loop fuel control, if you really need wideband, put in a second sensor and leave the stock one there still

[GTS GAV]

ok buddy i just thort i would get someone elses oppnion seams you no your stuff thanks for takin the time to exsplain it buddy

I've always had good luck with techedge stuff since years ago.

I think alot of people including myself until you
said actually need to realise that basically 100% of cars rely on the o2 sensors input. Not a wideband readings but a narrow band
granted many many people need tuning with a afr probe up the exhaust which is basically a downpipe wideband or as good as your going to get.
loaded conditions are calculated on a stock ecu from Toyota, so they know what is good what is bad on a stock motor.
Modified is always going to be custom

in regards to power fc being old school. Granted it is old tec, but it's doing me very well including my old rev2 which is also still running a powerfc and doing very well.

Old tech or not, there still doing the business IMO.

I personally would not run a wideband to the ecu, as an extra saftey device sure I agree it's great., but hooked directly, am not sure.

I don't care if this aem unit hooks up. Monitoring afr's regardless of ecu is always a good gizmo to have.

I personally am very tempted by the new analog aem unit!
Looks quality!

LinkPlus G3 EMS and have a AFR gauge for the dash

...If it helps you I run an Innovate wideband set up with my Link G3 XLEM ECU. I actualy ditched the gauge (sold it on) because I have the Link Display so can view all the parameters through the ECU now BUT I could have kept the gauge. The Innovate gear uses a Bosch sensor and a VAG controller which is fitted as stock on allot of production cars now. Gives wideband and simulated narrowband output. I got my Innovate kit from Graham Goode Racing in Leicester (reasonable price when I bought anyway) -it was between Innovate and AEM in terms of specs when I was looking for a wideband anyway.

Yea that's your run of the mill sales pitch going on there...

i used to run innovate stuff and it was fine, BUT i had costant problems with the DA C chips on the analog outputs blowing, got thru 3 controlers before giving up just a design flaw on em i guess, everytihng else was spot on
