Can ya post the MSQ and log here I wonder ?

[petew]

I'll post a screenshot. Gotta take it for a drive and get it to misbehave first.

So finally got a chance to log a drive. Here's a screen shot of what's going on...

Low throttle jerkiness.png

Seems to be happening right down the bottom of the map, not matter the revs. 40-60kpa. The higher the revs the less jerky it is.

Looks like your timing is bouncing between a couple of cells when the rpm fluctuations occur, may need to tweak/smooth that area?

Is that from the Accel PW spike? (yellow)

.....also can you post a screen shot of just the SPK Spark Advance and the AFR and the AFR Taget 1

AFR sensor is junk. Only works intermittently.

What AFR are you using? Have you tried to recalibrate it? Hope you get it figured out.

You can't tune if you don't have a reliable O2 sensor.............

Yeah, got a new one. Need to fit it, but I also need to move it. There are a few other life things getting in the way of that at the moment. It's an innovate LC2.

BTW, I bumped up the cells in the trouble zone and it smoothed things out some.

but I also need to move it.

Where is the old location and the new location ?

[petew]

Old location is just before the muffler. New location is on the bend much nearer the turbo.

Reason I asked is cause of the debate of length from turbo etc. Innovate says 24" downstream of the turbo.
