If have closed loop and a wideband AFR gauge will i need two lambda sensors?????

Steve

 

Yes.

 

Bugger....more money

Steve

 

but if the controller has a narrow band output why cant he use that ?

 

Just use a wideband gauge with the wideband sensor/controller...Take two bottles into the shower? Not me!

From what I understand narrowband sensors/gauges are better off in the boot anyway.

 

Im looking at something like this, but didnt know if i could use just one Lambda sensor.

You don't want to interfere with the signal from the lambda into the ECU on a closed loop conversion.

Cars that are running one lambda sensor for 2 purposes generally seem to throw lambda errors and struggle to lock to lambda at idle and under cruise.

I'm using the AEM wideband lambda kit with my AEM ECU, one lambda sensor for 2 purposes - BUT mine has been designed to do that

 

that link you have has a wideband controller which provides an emulated analog output to feed into the ECU.

providing it works properly (which i have no real experience with) it is fine

so it goes lambda -> controller/gauge -> ECU

 

but will it ? as if its a cossie ecu will the values match

 

they are programable outputs so yes

 

iirc the innovate controler can be adjusted to whatever output you want,

but i was always told to not use this function for closed loop, for the reasons will mentioned

 

so best ask who is the programmer of the closed loop software

oh and just to add the minute you mess with any settings on a innovate then it will be unreliable

 

A lot of LSU4 controllers will have two outputs so yes, you can do both with a single sensor.

 

I think i will just use the two sensors, it seems a hole lot easier.

I use XD-16 innovate kit and it work like oem lamda also. closed loop worked fine - it hold 14.7afr. and I didn't change any settings, just connect to ECU analog output. and XD-16 digital gauge has better precision then analog gauge from link, better to use xd-16.

 

there is a forum for innovate which maybe of some use
here..

Innovate seem very hit and miss at the mo as to whether they work or not, they dopn't seem so much to fail, just don't work to start with a lot of them.
Had two for a TVR, both duff, but was mapped without(closed loop) anyway perfectly.
