Ok, So I got my A/F gauge installed the other day and tonight I got it all calibrated and working correctly. Then I went out on a test drive. What I saw is REALLY scaring me.

When I am just cruising around my A/F stays around 14.3-14.5 which is pretty much were it should be. However as soon as I get on it and the W/M comes on my A/F drops down into the 10.2-11.2 range!!!! THAT IS LEAN! This can not be good for my engine. I am almost thinking about taking it all out of the car so i don't blow something up! Should I be worried about this? I need your opinions.

That's rich.

Did you just slap the W/M and not get retuned?

You could prolly do some tweaking and work the timing/boost a bit.

 

Ok, so if I go in and advance the timing it will fix that problem?

Josh

 

Well the best thing to do would be to log your car. That way you can see what is exactly going on.

 

Ok, what blocks should I log? I am new to this whole tuning thing so I want to make sure I am doing it right.

can u explain where the w/m kit and the a/f reading is installed on the car? like where the injection point is and where the a/f sensor is

 

The w/m is injecting in the bi-pipes. One on each side. The A/F is getting a reading from the wideband O2 that is installed in the exhaust system.

yeah everyone I know has to get a tune once they get the w/m kit or jsut a mister here is link for a mister and what he did after the install.

I'm more or less just thinking that it's misreading the results and not taking the w/m kit into account, but you said it was calibrated to factor that in, right?

You should, as said before timing and boost should be adjusted to get the best results.

You aren't misfiring or pre-igniting are you?

 

Nope. It runs great! It pulls forever too because of the lower IAT temps.
