Tuning Noob Need Help with Initial Setup

[blizz99]

Well, I'm trying to figure out how to get the car to idle right and be able to tune. Some help would be highly appreciated. Here's a log of my idle. I'm pretty sure my problem is that it's not going into closed loop. Let me know what you guys think.

The first things i noticed is that everything points toward it being lean. check your o2 sensor and make sure it'd working correctly and plugged in. also your airflow per rev is quite high. have you done a boost leak test?

Your Grams per rev are up at .4
It needs to be at .25grams per rev.

You will need to adjust the MAF comp sliders at 0-50-100Hz until you see it the grams per rev come into .25.

Or just do the MAF Auto adjust.

Hey man yea i had the same issue what i did as a quick fix was narrow band simulation. All you have to do is log you wideband then just check the box.

I just put in a new o2 sensor

I'll do that today and see what happens

Can you do that in ver2 or is that only ver3?

 

[jdigitty]

I'm not sure. I have Ver.3. It's on the tabs on the left it says "NBO2 sim".

Did you ever find out what the actual issue was?
