Looking for tune input

[devlmaycry]

Ok, I've had a couple of threads on here fishing for info in the past and have finally aquired an EFIlive V1 cable and have started tuning my car.... Since I finally got tired of throwing money away to other people to not do it right.

Here's my mods list:
Car: 1995 240sx
Engine: 2003 Cadillac Escalade LQ9 Iron Block 6.0L 10.1:1 compression
Heads: Pontiac G8 GT L92/LS3
Intake: 2010 Camaro pull-off LS3
Throttle body: LS2 2005 GTO 90mm DBW
Cam: EPS 222/230 .597/600 114LSA
Lifters: LS7 GMPP replacement lifters
Pushrods Manley 7.4000 stock length hardened
Springs: PAC 1518 beehive
MAF: Stock Truck MAF
Gas Pedal: 97-04 vette
TAC module: 97-04 vette
Dr. X-link For full throttle range
Transmission: 2004 GTO 6spd
Clutch: LS7 clutch kit with flywheel
Rear End: J30 VLSD R200 3.916 ratio
Tire Height 25" (255/40/17 on 17x10" rims)
Harness: Truck modded and pinned for manual trans

Anyways I'm looking for someone to take a look at the tune file and see how things are looking in there. I used the calc.vet tutorial, idle to tutorial, and the lean cruise map from the monaro. It seems to pull pretty good now, but still has some warm engine idle hunting. Right now I'm just looking to make sure I'm on the right path and take in any input on what needs corrected and what I'm doing right!

Did another log after fixing a charging issue and also fixed the mph settings for lean cruise... 200+mph was a bit high for my daily driving and lean cruise kick on. I will probably do another few logs since I noticed around 5800 and up it leans out to around 15.6.

[devlmaycry]

Im not sure i have my lean cruise figured out yet. However my logs seem to be changing the ve table less and less so Im guessing that its about right. I don't have a dyno but I know its pulling harder and driving better than it ever has.

[devlmaycry]

Things are looking ok, except I keep getting a pending p0171 p0174 for lean bank 1 and 2. Anyone have any ideas looking at the tune (or anything I need to post) as to what could be causing this?

Here's the newest log I took while driving earlier. You can see that when I'm cruising it starts to hit around 25% in my LTFT. My AFR's are still coming in around 14.6-7ish, but could this have something to do with the LC settings?

[joecar]

I think you should disable lean cruise during the tuning process... I think lean cruise may interfere with the LTFT's being correct (I may be wrong), and Calc.VET relies on the LTFT's being correct.

[devlmaycry]

I went ahead after I posted my question and removed the LC from the tune. I haven't had a chance yet to see if it fixes the issue. However, I will post again tomorrow once I reflash the PCM. I don't remember seeing the pending codes before I enabled it, and hopefully it will clear up with it off. I'm also thinking since I don't know a whole lot about LC, and info on it is scarce, I will leave it off until I can get a better understanding of it.

[devlmaycry]

Argh! This thing is starting to agravate me. I went ahead and made sure that I didn't have any air sneaking in after the MAF and sure enoughI found a couple of clamps on my intake that were a little loose so I tightened them down. Went out and did a few runs and kept getting a p1514 and went ahead and mulitplied the ETC expected airflow by 2. Now it's not wanting to idle right and hunts real bad. I thought maybe it was something do do with the AFR's from the air sneaking in and did a few runs. The MAF cal is looking good with most of the numbers reading .96 etc. The VE table was little off but nothing crazy. So now I still keep watching my LTFT top out at 25% under normal cruising. It's starting to get frustrating that I can't seem to get normal cruising right. WOT seems to be fine, but normal driving is killing me.

I will also be checking for any other posible leaks come wednesday.

[devlmaycry]

Joecar thanks to your excel sheet on the LS3 injectors I was able to get the correct IFR, and a couple other corresponding maps (as far as I know.) Now the LTFT seems to be lined out and the dead spots under regular cruise seem to be ironed out. However, the idle still wants to hunt a few times before settling on the set idle. I have tried this tune with and without the idle quide adjustments and it acts about the same. So, I'm still trying to figure that out.

Thanks :cheers:

Some of this may help with idle tuning:

Ok, I have copied over a lot of the 6.0 truck tables for things and the hunting idle seems to be gone for now. However, I still keep getting rich bank 1 and 2 codes. I think a lot of it comes from the fact my idle dips to 11.2 AFR's then comes back up to 14.7ish, and especially when I start it the AFR's stay around 11.2 to 11.5 for until the engine gets above roughly 100F. I've read through several of the idle threads, but I don't know the mechanics of what all actually pertains to idle and how it all works to be able to know where I can change it to fix it.

I have attatched a log file and the current tune file. Hopefully someone can look at it and give me a pointer on where I can adjust something to help line out this (hopefully) last little issue!

Just changed b4349 to 0.0191 vs the stock number, since I have a 90mm LS2 tb.

Noticed when I was leaving the theatre that it likes to hang up around 1500rpms and then drop down once I'm at a full stop. Earlier, and once it's warmed up all the way, it hangs at like 1000rpms and then drops down once it's at a stop. 1000rpms is ok 1500 I don't really like, and I'm 90% sure it's something in the truck tables that I don't understand.

Well after the reflash and looking into a couple more things the idle seems to be better. However, the only problem I seem to be getting is a p0172 p0175 the rich bank 1&2 codes. When I first start the car the AFR is around 11.5 then once it warms up it comes up to 14.7. However once I come to a stop from driving it dips to 11.5ish then makes it's way back up to 14.6.

The low AFR on cold start I imagine is from something in the cold start tables that I don't know how to line out. Though I don't know what's causing the AFR's in the 11's when I come to a stop.

Fingers crossed that someone with more knowledge than me will chime in with where I can start looking for this fix.

Are you doing the calc ve tutorial? your ve table looks a bit wacky.

[slows10]

Your maf table looks wrong as well.

That's the link and the guide I used. I was thinking that my MAF looked wacked where it humps it's like it just didn't pick anything up after that. I was thinking it was supposed to look like a nice smooth curve. The VE table I remember looking significantly different on the stock tune. However, despite all the looks at my thread your the only one that has mentioned that things might look a little wacky. Under normal driving things seem to be ok, but that idle is stupid rich.

That being said what do I need to do, post, or etc?
