SD = no MAF
OL = no LTFT
CL = LTFT

MAF can be use in OL and CL.
The "tutorial" tells you after tuning in OLSD,
enable LTFTs (CLSD) and check that LTFTs are between 0% and -5%.
This will not happen period.
If you want LTFTs between 0% and -5% then tune with them and
use your WBO2 for WOT.It sounds like you may need a new O2 sensor.
With the LC-1 when a sensor goes bad you can see
unreasonable AFR under load when you know it should not be or
it may get Error 8.
If AFR at WOT was really that lean you would know it.
If the car pulls and does not miss or get KR most likely the sensor is shot.

For the 0 to -5% on the long fuel trims, what rpms should I look at?

Here is at a 55 HWY speed... So, why is one at -6.2 and the other one at -.8? How can you get those closer together?







And suppose I go to the track and temps are different, thats going to mess with my AF right? How would I adjust it?

bank1 and bank2 LTFTs will be off from each other,
that is a fact of life with the LS1.
Reset them before logging and drive for a while, LTFTs take a little time to settle
Tuning with LTFTs and WBO2
Use the average LTFT of both banks.

Ill change the 02 out on that side to see if it will help get closer to 0, its the same side where I have my WB02, maybe both are on its way out since its the same side.. I have another WB02 on its way. How would you reset your LTFT?

So, what is the pros to all this.. I mean is it suppose to net more power, easier to adjust, etc?? On a SD tune, how far off does your tune go, AF wise, when the weather changes?

There are sometimes I go to the track and in the morning its 50* out, so if I tuned the car in 80* weather will that cause my tune to be wacked? If so, do I just add some percentage to B0101 to lean it out?

I think I am going to leave it in SD and give it a try.. The car pulled really hard until I let out of it due to me seeing 60 on my AF gauge.

Reset LTFTs with the scan tool. SHFT+CTRL+F2
Pro apposed to what?
OLSD has none IMO.

To reset it wouldnt you have to load up the same tune so it starts "learning" from scratch? From what I understand what your saying will be the same as just opening up another log, youll still get the same LTFT's.

Uggg, which way should I try to dial in the car then, am I just wasting my time woth OLSD?

Im wannting to get the car dialed in down low for driveability.. It wants to die (but will catch itself) when I have to stop pretty quick.. From what you guys have told me I have to do all this 1st before I try the idle tuning so I might as well do it right. Why do it OLSD then?

You can do RAFIG at any time and you can manually reset LTFTs without reflashing.

Ok, now what is this RAFIG you speak off?

I still dont see how reseting the LTFT's on the scan tool will reset the PCM so it erases all old info/data.

[mr.prick]

The first post in the idle tuning link in my sig has a link explaining RAFIG process.
RAFIG is a calc.pid that you add to {B4307}
IAC - Short term correction + IAC - Long term correction = CALC.RAFIG

[waterbug1999]

Ok.. ill see how much I dont understand about that and get back to ya. lol

Should I do the idle tuning 1st since its in that thread?

Whats the pros to tuning RAFIG?


Thanks for your help by the way.

So question.. went out and I saw my commanded AF was 12.45 (WB02 was about the same) at WOT, how do I up a little to get close to 13.1?
