LS tune help

[Lshungy]

Hi to all !!
Have only been using HP tuners for a few months now and its been a very quick learning curve !! I have a couple of quick question to try and get my head around how this software works and try and figure my problems first before i post up some tuning logs and files etc .
1 : In the EQ open loop table can you command a lower ratio than 1 in the low map { say 40-60 kpa } range to lean out cruise AF ratios ??? Ive tried changing the numbers but they dont respond in the scanner when logging . I can get them to change going above 1 before PE engages for a smoother transition or part throttle overtake etc but not below .
2 : Ive tried every effort to enable the lean cruise tables but have had no luck { yes its an AUS based platform ECM } the only thing that slightly happens is that is does lean out but only at a higher than commanded rpm range approx 500rpm but this puts my cruise speed to high .
3 : Ive also discovered that I can change OS systems to take advantage of the RTT features but under my OS tab in editor I have a blank page which apparently means I have a custom OS {not sure what that is } and I need to re flash back to original to enable those functions ???

Ill leave it at that for now except that this is a Mafless SD tune .
Bit of a back story to this vehicle / tune which i can explain but dont want to complicate the thread.

Any questions please ask and ill try to figure the tune/logs uploading in the meantime.
Cheers Carl.

You need to post your tune and a log. Especially since there isn't a lot of people familiar with the differences for the AUS versions.

Plus any information on the build/mods and what you are actually working on.

Looks like they have worked , so a bit of background info.
This a conversion for myself nothing uncommon ,LS1 5.7L into a 105 series landcruiser with a turbo 400 trans. Short story is the ECM I'm currently using is not the original from the motor originally purchased { apparently lost by the first guy } This lead me to getting a simple stand alone harness made by another guy who was also able to supply another ECM which I asked for to have a basic setup flashed into it enough to get me around the block to check for leaks / pressures / gears etc etc which it did . Wasn't the best but drivable . Time passes and I get the car all sorted ready to go to the dyno to have it properly tuned and all the idles/ cold starts sorted etc . Car comes back driving like it should with no problems whatsoever.
Put quite a few K's on the car enjoying it but it sort of lacked a bit of torque and just felt a bit flat all round. Kept telling myself that it was just a mild motor , heavy car , tall tyres gearing etc and maybe that's how it was .
Well curiosity got the better of me and I purchased HP tuners .
A bit of simple looking around on the basic tables lead me to find that the dyno guy had set up the spark tables what appears to be correctly then just taken a blanket 9 or 10 deg out across the whole table , no wonder it felt flat !!
So ive done small changes here and there which has made a huge difference but im now starting to chase a bit of economy if possible hence my first questions ..
Basic engine mods small cam , shorty 4-1 factory headers with modified larger collectors, high flowing exhaust no cats,Maffless pipe with cold air snorkel feeding an aftermarket airbox.
Hope this helps Cheers Carl..

Anyone?s Crystal ball working today ?

[Lshungy]

Ok so I'm guessing there's not many Aus based guys on here ?
Would I be better off get a different stock ECM and starting again ??
Cheers Carl.
