    Thanks! Worst case, it's a 5.3, easy to replace. I sent off the oil for analysis and it came back perfect, so I know I'm not hammering out bearings or anything.

    No critique? I've been driving the car in the wild weather and temp swings we've been having in Texas lately. It feels great and I haven't noticed any glaring issues.

    5.3 LM7 1989 Firebird, first tune

    I've spent a lot of time tuning this car and just finished a T56 swap, which necessitated going trough it again. I bought this car in highschool and finally got it finished up, mechanically at least....

    Interesting, I have a 2006 Jeep Liberty KJ 2.8 CRD that uses a similar setup to your JK I believe. I'll have to see if I can get them to add this TCM to their list as well.

    For anyone who may wind up here on a search, HPT cannot edit certain parameters and there are a number of different strategies that were used for 7.3 vehicles. In addition to that, Ford used adaptive...

    2001 7.3 tuning failure

    Has anyone tuned or tried to tune a 7.3 yet?

    I have noticed a lot of odd or possibly incomplete tables in HPT. If I try to click the 2-1 Downshift TV pressure table, HPT crashes. Under Engine...

    Help needed on 2011 F-250 6.7

    I just bought a 2011 F250 6.7 4x4 FX4, I have HP Tuners for my GM F-Body cars, but I haven't tuned a diesel with it yet. The first thing I did was compare it to the closest stock file I could find....

    Wideband and new NB O2s will be next for sure. Shoestring budget at the moment. Isn't just changing the stoich to 14.3 without modifying anything else a bit careless? It certainly smells god aweful...

    No such luck with the O2 changes. I got the driver's side to read a decent bit, but it is still weak. I'm going to replace the O2s and try again. Here is the tune and log from today.

    I'll give my tables some adjustment and see how it does. I see yours are modified by about the same values as the other thread stated, I'll keep increasing the O2 Integrator delay until I get some...

    That's what I am tinkering with now. I went ahead and replaced everything in the tune file with 5.3 stock tables first so I know what baseline I'm working with. The only thing not from the 5.3 data...
  12. Thanks for taking a look! When I was going back...

    Thanks for taking a look! When I was going back through to cobble the tune together last night, I smoothed out the main spark and idle/gear spark tables and made them a bit less..."Canned". VE looks...

    Ok, I cobbled together an entirely new tune file. For some reason the original I posted was not behaving. I went through page by page and made sure everything was changed over to 5.7 data, it's a...

    When you blip the throttle the trim cell changes to one that's probably not being hit frequently if at all. When you are holding high idle at 1500rpm and the cell trims again to roughly what normal...

    Try this one I attached, I've noticed with the new version I can't modify any OS properties. This one might be unlocked.

    That's what is bothering me, I read a bit about modfying O2 switch points...
  16. Installed longtubes, now STFT/LTFT at idle are pulling fuel out

    I have a 5.3 LM7 with a SLP 234/228 cam, LS1 intake, and longtube headers. Previously the car had manifolds which I knew would hold it back. It was tuned with the manifolds on it, and after...

    Converter dying or tuning error?

    Attached is a log and config file I use to log trips in the car. The issue starts right around the 7 minute mark. I have a 2002 Z28 with a stock 4L60E. I've tuned the shift tables, TCC duty max/min...

    I smoother VE and made some small timing changes. I don't have a wideband yet so I am playing conservative with WOT and PE tuning. I'd rather be slightly rich than forcing it too lean during hot days...

    The PE values are stock. I was told that they weren't used for LS1 cars the way they are tuned.

    Stock is:
    15kpa for MAP enable
    Hot PE throttle is disabled by being set at 285*
    PE Delay is...
  20. Anyone mind reviewing my tune and log file?

    I have a 2002 Z28 that is mostly stock outside of the catback and SLP lid. It has about 144k miles on it and I just got the car after being repaired (it was hit by a drunk). I'm just starting to...

    Attached is a stock tune from my 2006 SRT8. It is a NGC3 CAN car. You will need to use the beta software to read it.

    I have a 2006 SRT8 as well. Apparently they came with one of two ECMs, the NGC3 or NGC3 CAN. The NGC3 CAN seems to present some issues and is only supported in the 2.25 beta. I have done some fan...

    Awesome write up and answers some questions I had about why my hot start seems to be slower compared to a cold start. I'll have to give this a try, thanks!

    I'm likely giving the wrong impression, but there is a confidence that an engine should start with. Generally on start up, the revs hit ~1500 or so, and immediately drop to desired cold idle RPM,...

    Tuning for a quicker start?

    I've always had one big gripe about the LS motors on start up: All of them seem to start slowly.

    I have had 3 LS cars and 2 LS trucks. The common issue with all of them is that especially on a...
