Be sure to set the RTT Mode under the general engine tab, I forgot to enable it there, so when scanning and hitting the RTT button, it activated RTT but left everything greyed out. OOPS!

My camaro does the same thing, it will idle fine but let it sit there for a while idleing and the AFR will start going from 14.7 area to like 18:1 for no reason does it both in closed loop and open...
I am having the problem where I tuned my VE and MAF by wideband in open loop and got the %error down close enough to zero for my liking. After the VE and MAF were tuned I put the car back in closed...
Mine runs very lean on idel from time to time as well, not sure what is going on. The enrichment is from the OLFA during startup correct, it is commanding like mid 12's to 13's but it is idleing at...
How do you turn off LTIT and do you turn it back on when done RAF tuning?
Just noticed a new release date of 5/2
I think the one I got was from 4/28, maybe it is addressed here
What changed or what bugs were addressed
How do you disable the LTIT and is that just temporary while tuning or do you leave it off all together?
I d/l the new release and cant get RTT to work anymore.
Before 2.22 it worked fine. Now when I connect the scanner I get the RTT icon to popup and it opens the new window for it, but all the...
My OLFA is set up showing enrichment, i think it is the MAF table maybe I played around with it some more to see, it was showing my trims quite positive after doing an OLMAF tune with wideband
Make sure EGR is enabled otherwise it wont record therefore giving you zeros
Look under Engine->General->EGR Enabled
I will do a log when I get home and post it, but my LTFT are -2 to 2 pretty much all over and my WOT afr is on the money, so I believe my fueling is plenty good enough outside of idle. my idle trims...
Are you referring to LTIT and STIT?
I will do a cold start log using the Russ K config and post it up later
What else should I monitor?
OK lets bring this back up...
I am still getting that dang Random Misfire code seems like every other time I drive, but notice it really when it sits idleing for a while. I still have the same...
I am having an issue with my idle and going way lean from time to time. I have done a few of the russ k idle-config tunings on the RAF. it doesnt stumble or hunt for idle, that part is just fine. ...
I would think you would not want to disable PE, I mean that enrichment is taken into account in your cammanded afr which is being checked against your wideband.
Again sorry for the confusion on that, I wrote it at 2am on a work night :D
I tweaked it some and added a few notes to the end about that issue
Its not perfect but it will definately help you out...
The reason I put the CL then OL was for my case where my trims were somewhat aggressive while in cl, so I used closed loop just to get the trims closer to zero before i went to OL and keep my fueling...
I added a revised version to the first post
Thanks for the input 5LE, i will do some updates
Narrowbands are the stock oxygen sensor, only accurate at 14.7u afr
Widebands are aftermarket sensors which are more accurate for tuning where the a/f is not 14.7 such as wide open throttle or power...
Could a mod look this over and maybe make a sticky of some sort, if not no biggie
If anybody has any corrections or additions let me know so I can update my write-up
I have seen a lot of how to...

That is slightly smaller then my cam and I have mine idle at 900, so just start with what is in the link to get your idle...
Cool thanks, just making sure I didnt loose a previous enhancement
I have the older serial port HPTuners (it is licensed for all 2001 and 2002 F-Bodies) and I recently purchased the 1 Bar MAF enhancement for my own car. It worked great, but my question is... my...
the reason i ask is because when i was in OLSD mode and maf unplugged when scanning the timing table seemed wrobg it was all at the top of table instead of all over rthe tablwe
