I downloaded the bin from my car and edited that.

Do i have to upload a custom bin for the vy v6 flash ecu's ? I thought you used to stock image.

You can used the stock bin you got from your car but there are 2 XDF files that are for the VY.
You need to make sure you have the right XDF or the changes you make won't work.

Are you trying to increase the target afr or are you trying to increase fuel so what your wide band is reading matches your target afr?

Just switch to enhanced code and start again. Great code and all matching and high quality XDF and ADX files.
Only way to do it in my opinion.

Tuning doesn't work like that. AFR has very little effect on power compared to timing.

One does not just "tune the car". Maybe it is a good idea for you to take a step back and do alot of reading before you go any further. Read this forum especially the Holden ECU & Custom Code sections, and the FAQ.

Custom code section. From what was said earlier. Your bin is modified but nothing logical so fair chance your XDF is mismatched. What are you using for logging AFR now?

Dyno Dynamics Dyno

Obviously my xdf is not correct for the bin file in my car which is why I am not getting any changes in fueling.

I want to see if it will make more if i lean it out a bit, its running 12.8afr in the top end and I would like to try it at around 13.3 and see if it makes some more power, if not try going down to 12.5 and see what it does.

There are 2 xdf's that were available that i saw, I was using 24060a v2.63 , all other maps looked fine, but when i changed to 24060b v2.41 the inj mult map has no 0's in it now.

I will try put it back on the dyno today after I finish my other jobs and see what is left in it.

So far I have got 135rwkw from a stock 320,000km v6 with just a upgraded panel filter and a set of headers and 2.5" exhaust.

Does that sound about right for it? the car had 114kw completly standard.

Should be a little in it when I find out what fueling it likes.

Cheers

Was able to tune the fueling when using the correct XDF file.

Found this engine lost power when i leaned it out, put a little extra fuel in it and it gained 2 or 3 kw.
