Striped down vx tune

[pas94]

I think the chip is stock I'm guessing that it was changed back at some stage.
looking at the check sum cf the one I down loaded here all looks to be the same ... Oh well time to try flash tool I guess, unless I can work out the new check sum with the vats turned off.

Actually using the difference tool shows differences looks like it might be good after all

what do you guys think? timing map looks odd like 10 deg less timing than the one I'm comparing it to maybe I have the wrong xdf or bin or they put timing in somewhere else?

needs VY V6_$060B v2.4 xdf to read

[pas94]

thanks wizard, what would be the factory bin for this ? I cant see it on the page there, the one i have tried looks better with the other xdf
Also is there any way I can calculate a new check sum? I can't rember how I did this with a mem cal I assume it would need up dating there too or does it not look at it on start up?
IE if you change settings in tuner pro (non realtime) and try to reflash (eprom burner)wouldn't it need a new check sum?

i differenced it against a couple of the stock bins off here not many changes p/e airflow limit to try save fuel and lower fan temps and all the other normal chiptorque mods

[pas94]

Normal torque chip mods...?

[pas94]

Any idea on the above question about check sum? That's all that's stopping me now.

A good xdf will re calculate that for you and or flash tool as well. Look at the enhanced bin's they have it set to AA which makes the code by pass that check. Set it to AA then when flashing let flash tool do its calculate function and should be good.

normally flash with vl400's flashtool that automagically fixes checksum for me LOL
