I have a 2000 ls1 with a torque v2 and prc 225 heads. The converter is a circle d 3600. I am running speed density and am currently trying to tune the ve tables using a wideband. The problem I am...

Thanks MMGT1,
here is another scan where I only used 20. sorry I didn't post the config earlier but here it is now. I am using an ngk wideband. This scan is with another maf just like it and it...

Really no one?

Did you mean after the cats?

You can have an extra bung welded in and put the wideband on that bung and leave the o2 sensors plugged in still. Although idk why it would benefit to have them still active. If your tuning with a...

So it is normal for our maf frequency to swing a bit?

I had an issue something similar to this. My maf frequency looks spikey when going wot but everywhere else looks good. Cant seem to get any response whatsoever on this forum. Im starting to lose...

Anyone?

On the scan attached, at every wide open throttle you can see how the calc cylair value has several spikes. The maf frequency is a little spikey too but it seems like the calc cylair is amplified a...

It is a zex wet kit shooting into the intake tract. It hasn't backfired at all with this new build and it didn't backfire before. Just when I would use the juice at the end of a pass it would pop. I...

I have an ls1 with ls6 intake torquer v2 prc 225 heads and a 3600 circle d converter. Should I enable dfco if I am going to be using a 175 shot of nitrous. The reason I ask is before I built this...

Ok cool thanks I appreciate the advice. How do you go about adjusting the timing? Do you basically just guess at it with what you know and monitor knock retard?

Ok thanks ill give that a try. Maybe I should hook up straight to the battery as well. So when you tune the ve tables do you still keep it in 1:1 and drive steady down a road?

When logging I actually stay steady in one cell until it gathers around 50 counts then gradually increase throttle to get into the next cell. I am using Greg Banish's method of tuning the maf with...

Also im taking these readings while driving down the road in first gear reaching every point for at least 50 counts

I am tuning an ls1 which I recently installed a torquer v2 and prc 225 heads with a 4l80 transmission. I just got started on the tuning and haven't got far. This is the config file I am using with...
