AFR Reading on NB Sensor?

Post by phoenix3d »

Hi Phillip...

Could you please check out the "AFR" readings when in Narrow Band Mode.....

I constantly get 14.7:1 at 0V.....? On stim

MT & Megatunix Read correctly....

When I change to Wideband Mode (Obviously with a Wide Band Stim connected) it read correct.... (Specific 9-19:1 TechEdge Sensor)

What Could it be? :?

Cheers
Gordon.

Hi Phillip...

Sorry brain farted... forgot to mention firmware....

We were playing on my buddies MS1 - HR11d....

Don't have logs or msq's... but can try get some for you by the weekend if I can get hold of my Buddy....

We were trying to dyno the car.... But could not get his NB sensor to read properly.... So we switched back to MT and All was perfect...
We had a second look in Megatunix.. and that was correct aswell....

So we thought we were being stupid..... Tried TS again... No luck... Read 14.7:1 with the car no running, as well as Sensor unplugged.....?

Thanks for the reply..

Yeah, I probably need to see the project as it is certain that something is just miss configured in your TunerStudioProject.

Does MS1 output the WB sensor value when the engine isn't running? Seems like it doesn't. Can't remember.
