I'm using the Diablo Tune No DOD... for 93 octane fuel and with the DOD disabled/turned off...
the factory HP tune is just for you to make your own changes to the tune that is currently in your car, it's not a pre-set tune like the Diablo tune or 91 octane tune...

It's a problem with the 1794. I get about 1:15 myself.
It's enough though, even if your only getting 30 seconds. Take it up to crusing speed, already set up to record a log. Give it about 2 or 3 minutes to settle on cruise and trigger your log. For the WOT, well, if your can't get a quarter run in 30 seconds, you need a whole lot more than the predator. lol

Just wondering what the optimal ranges would be for the LS2 06 GTO. You mentioned in your post LEW the ranges for your Monti but where would one find the optimal O2 sensor ranges and thus calculating the correct LTFT and PE. Any help is greatfull.
they would be the same...

You haven't heard from me in a while. Did a few things. Went back to the stock tune but adjusted LTFT...they were also pretty high. Reset the PCM overnight, and just cruising for a while. So far so good.
MikeL is sending me an adjusted performance tune wiht the 4-3 downshift requiring little pedal effort. When I get it, I'll start over.
PS also changed plugs, killed my wrists in the process LOL. Went with stock Delco Iridiums.

Hey JR! That's cool... let me know how you like that new downshift setting... maybe I'll have them do that for me 
so you're running the stock/OEM tune now??

yeah slightly modified with the Predator. Fansettings and lowered LTFTs -5%. I notice the O2 readings look ok so I'm gonna leave them alone for now.
Well I got the tune back from MikeL
HOLY CRAP !! Monster tune ! I have no idea what was done, but this thing is awsome.
I originally asked to program the 4-3 downshift "easy" so it will shift with little pedal effort. I wanted this to avoid the pings when lugging @ 45-50 mph...normal driving.
Not sure what he did, but it feels like "all" the downshifts got easier, not just 4-3. And the pings part throttle @ 45mph are GONE. The tune is very responsive, feels like I gained so much performance it is outstanding.
I did detect some WOT pings over 5k but those are easy to work on with the predator....it's those part throttle ones with no adjustments for that are the killers.
I see high 11s in the LTFTs so I guess I'm running VERY lean, hence the WOT pings. Now I know how to adjust them, so off I go !!

NICE!!! Mike/Johan, can I get this shifting adjustment made to my tune??
...and if you guys are able to adjust this, then the tranny update/support must be ready, no??

I need the data viewer 3.0 and it is not available for download on the website only the new versions are. Can anyone post a link here to download the old version so I can see the correct AFR at WOT. Can't someone fix the bug in the new versions?

the new dataviewer works... they updated it...
when you get your log, if the AFR is showing incorrectly in the dataviewer, up at the top menu of the dataviewer, go to:
View > Parameter Modifiers > E40 Equivalence Ratio - Invert... and this will show the correct AFR.

they won't both be exact anyway, but as long as we get them between 0 to -2, we're good. so you can adjust the slope to -4%, then drive for about 30 miles to let the change/adjustment settle in, then do another log and see where the average ltft's are at then.

My Programmer U1794, only logs for 30 seconds before it says the log is full. I have only selected 5 parameters......
Any ideas? Monte's instructions suggest that 20-25mins of logs.

get as much as you can... it's better for getting the ltft's figured out and dialed in... he was just saying you COULD use it if it was only 30 seconds... but you want to log as long as you can... more data points gives us better info on what adjustments to make...
