WIDEBAND: Is this normal? - TriStateTuners.com :: Home of Tristate Auto Enthusiast

*****THIS IS JEFFROS SPEC V********

I installed my wide band today.

The o2 sensor is near the bottom of the downpipe (before the divorced pipe meets back)

At idle its around 14.7, driving its goes any where from 13.5-14.5 and at full boost (16psi) its around 10.6

I'll post a video of it when I get home.

EDIT: Also, when I'm driving and if I come to a stop 50% of the time my car will just stall out. Any idea why? I've recently installed a front mount and the BOV is recirc with the greddy recirc kit.

The wideband readings sound normal. Does it seem like its going up and down really fast while cruising?

You might have a vac leak or did not reconnect all of the vac hoses that are supposed to be hooked up?

10.6 sounds a bit rich for only pushing 16psi... I dont know much about performance but for the videos and what I have read online, only Id say 20-25 psi + takes that much fuel... Id think you should be around high 11s for A/F but again, I dont know that much when it comes to A/F and tuning stuff.

Your idle A/F is dead on perfect if its at 14.7 but you want to get progressively more rich higher in the RPMs and load.

10.6 is fine. stock sucks for fuel trims.

Your car is stalling because well you dont have any Engine Management listed and without that your car is going to run...well like ****.

Jeffros Spec V · 05-10-2007, 11:11 PM

My car didn"t start stalling until I put my front mount on. Maybe I missed a vaccum line or something but I dont think I did.

get engine management, otherwise your wideband is just a light show. engine management. EM. got it?

Jeffros Spec V · 05-10-2007, 11:23 PM

I'm sure I have something.

There is no way my car would run how it does without it. I'm going to take it to Andy soon and have him check my **** out.

EM can't live without it.

dude you also are running at tune if there "was" one for a TMIC with stock BPV. stop modding and properly tune. recheck all those couplers since you mentioned that one blew off earlier. seriously its time to tune.

I have one thing left to do before tune w00t! w00t!

Tunes are for drunks and guys with to much money. Questions concerning not knowing what your doing and for the children.

yep prefectly normal thats where the stock airfuel trims are set which is kind of crazy. if you leave the boost alone and get those afrs to about 11.4 11.5 or so you will notice a huge increase in power and you will get wayy better gas millage.

Yeah, I need to get that things cranked up. Once I put my wastegate on I'll get tuned.
