I have been searching the boards and other places and really cant find what I am looking for. I have a LC1 wideband and gauge that I hooked up this weekend and the gauge and all is working perfect, I just need to know if the AFR is supposed to bounce around like crazy, at idle it sits at 14.5-14.8 slowly moving and I think thats normal. Under WOT it sits at 13.2 but what is getting me is part throttle driving I am bouncing from the upper 13's to the low 15's like crazy. Is my tune that far off and if I get it dialed is it supposed to sit around 14.7 and move around slowly? It cycles as fast as a narrow band sensor and I can barely tell where its at. Thanks!

 

???????????????Let me ask it a different way. How does your wideband react, does it stay around 14.7 or does it bounce all over the place ex. 14-15.00 AFR, OR worse. I dont know what it is supposed to do, bounce around or stay steady

 

its going to bounce around a little bit.....

 

Thanks for the reply, but I am wondering if it is supposed to bounce a little 14.5-14.9 OR 13's-15's. I see the number moving in the gauge so fast there is no way to tell what it is running, is that normal

 

Check for an Air leak. In steady state throttle cruising mine varys about +- .15. 14.5 to 14.7. Mine is hooked up off of the serial connection.

 

Will check for vacuum leaks, it sits at 14.5-14.7 at idle , I just think my tune is fk'ed up.

 

Not vacuum, exhaust air leaks.

 

In the controller settings what do you have the reporting rate set to? Instant? Slow it down to 1/6

 

Probably is Instant, whatever is default. I logged into the controller settings last night and some how changed my AFR values and I am reading 17 AFR driving down the road. Tried to set them back to the factory settings and damn thing would not update, would just sit there and do nothing, led flashing at me but I will try it again tonight and slow it down. THANK You!
