I have been unknowingly fighting injectors for a little bit now (turns out I dont suck as much at tuning as I thought), do you recommend flow testing after pulling and cleaning injectors? They are...

Another update for the crowd- changed injector data to known LS2 data, and the car drives even nicer. With that change I nudged the VE table a bit (still in closed loop SD) and the tune generally...

Update for all. Tune is feeling MUCH better now. Disabled the O2s and went full open loop off the wideband, seems much more predictable. With the O2s enabled my long term trims were massively...

Don't have a ton of feedback for you without a bin, would want to see your VE table, target idle, etc... And try out tunezilla for sharing logs, I really like it as its easy to share and quite...

Glad to hear that's working for you, did you seg swap? That bin is a 6L and has different injector flow rates

Set up a barebone PCV setup and roughed in some injector data from a GTO... From what I looked into- a good VE table should balance out what I haven't touched.

Set my default&minimum injector...

I am confident there are no leaks beforehand, I can investigate further- but the PCV and injector issues certainly need addressed. Thanks for all the help

Good to know, will investigate a comparable bin if I can find one... After a few seconds of thinking, I believe you are right on the money with the PCV potentially being an issue. Certainly seems to...

Yikes, thought I had this one pretty good. Its a returnless LS2 style intake manifold and fuel rail. Stock LQ4 bottom end, Elgin E1840P, LS2 Heads, upgraded springs and pushrods. Not running EGR (but...

Update for those following along from home.

Edited the tune a bit- modified idle airflow & spark values, changed idle to 900. Seems happier, but around a minute or two into each start my O2...

https://log.tunezilla.com/s/pMgoXXUT Here is the latest idle log I have here. Still working out the table with a fresh XDF/bin combo.

With a new tune all together based off the 04 Silv 6.0L Manual...

Youre a legend! Thanks for sending this over, should give me a solid start. The seg swap I just put together was making me a bit nervous haha

I had a somewhat happy engine with torque parameters disabled with my stock 5.3 before this, thought I could get away with it again. I will go ahead and try a more proper seg swap.

Those VE tables...

That makes sense, thanks for the reply! I will continue to investigate. All fuel trims are deep into the negatives, so I am assuming I can tune a bit leaner just based on that for regular cruising,...

Additional log from this session. From 136seconds to 200 or so its a 1,2,3 from dead. Died trying to let out the clutch a few times...

Any help is extremely...

I am struggling to get a decent tune on my swap project- its a cammed LQ4 (sloppy stage 2 copy cat cam) currently MAF disabled trying to set my VE table. My wideband is on the driver side right next...

I'm glad I saw this, I will have to try PCM Logger. I have been digging into OBDWiz and TunerPro to try and Log my wideband over EGR for a few hours now and I am really struggling to make sense of...

Here is the stock 6.0 tune from the actual LQ4, but it is DBC not DBW. I am not sure if I can segment swap all of the DBW parameters over from my 5.3 tune, but if I can this bin works great with my...

Sorry to Hijack this thread, but I have a similar request. I am still learning (enough to remove VATS, codes, trans, fans etc) but am not comfortable for setting my cammed base tune. I have a Sloppy...

Out of curiousity, do the DLLs need to be specific names for the XDF to know which checksum DLL to use? Interested in that Universal Patcher though, ill have to take a peek!

I have come to the conclusion of this: I am going to try and write a 12587603 P59 bin onto my PCM, as I have the ability to delete VATs etc. I also have a 6 spd corvette 12587603 bin that I will use...

Apologies on the delay, thanks Dave- you've given me a starting point. Looks like a 4.8 manual is the best path forward!

Hey Dave thanks for taking the time! What are the odds you have a HDW 12580786 DBW 5.3 manual bin lying around? I am not sure if im ready to run the copy paste marathon, still wrapping my head around...

Hello all, I am fairly new to the world of tuning and had a question regarding XDF and bin setups. I have a nice XDF and Bin for my ECU and deleted VATS quickly (keeping stock tune for now as there...

Hello all, working on a 1987 BMW 325e- currently refreshing the entire chassis and throwing in a 5.3 iron block (the aluminum 6.0 sent a rod through the block and hid nicely behind the AC compressor....
