Will try some more fuel in there and see what happens, im picking this is going to be the final answer.

No.. at this time the target AFR is simply for log comparison ONLY.

In the new version you will have a target AFR table that will be used for closed loop wideband feedback.. this table WILL adjust fueling to try to maintain your target AFR.

Yeah thats what i thought. Sweet as.

Bump on V6!

I am planning on tuning my car with it this afternoon, but I need to get the fuel pump replaced before I can do so.

The wideband target feedback is definitely one of the nicest new features. It is ridiculously adjustable so you can adjust it just to your liking!

Im holding out on finishing the tune on my car, got the dyno lined up so as soon as V6 is available i can wind the boost up. Just driving it around on .8 bar with a silencer in the tailpipe atm.

Finally got a chance to try some other stuff today. Adding heaps of fuel did nothing. I like to run in mid 15's at light cruise, richened the K value til it was cruising in mid 14's and it made no difference. Then added a big block of fuel in the low zones where it has the issue, and still no difference.

Then i decided to play with fuel cut rpm, made it some fc off was a lower rpm, seems to have made a slight difference. Will test more and post up results

I always had this problem with the car bucking at low speeds/rpm until last night. I cleaned the maf with CRC and most of it went away. Before it would buck around 2k rpm. Now its closer to 1.3rpm but I blame that on the s4's. Give it a try
