I need a 4L80E segment for OS 09379910. Is Holden Crazy the only place to look? I looked there and found nothing. Surely there is another repository somewhere on the wide-wide web?

What year, models used this OS? Possibly you can swap to one that has the 4L80-E available.

Im with Al on this, what car/truck is currently using this OS? If its an LS1 512kb PCM (99-02) then you can easily switch to an OS that has a direct upgrade to a COS.
Once we know what vehicle it's in, some tuners have their own vast array of stock files pulled from customer's cars. Wish I did, just have mostly P10 stuff.

If you can run OS 12212156 (512kB) on your PCM, there's a 12212156/4L80E file on the forum.
Not sure what make/model its from. I found it on Holdencrazy.com. It says 5.3 Radix, which is what I have plus an LS6 cam. The tune I have now is from a local tuner and I don't know much about it, except it is not "what my engine wants". I thought the holdencrazy tune I found might be the one Magnacharger provided with their kits, so maybe it would be a better base for me to start learning with. I full flashed it in last night and the engine would barely run it was so lean, at least 19:1 AFR. Also it never went CL.
So I think I will just load a stock 5.3 cal and see what I can/can't do. I'm afraid I'll have to bail out and send it to a dyno tuner. It is a highly modified Toyota mud truck that can't be street driven safely or legally, especially at speeds above 50MPH. So without a dyno, VE seems impossible. I just need decent idle, halfway decent part throttle, and all out WOT. I want as much power as I can sqeeze out because if I wound an engine, I can source another for aroud $400 and takes about a day and a half to swap it out.
So the file you found contains the 4L80E segment...?
No, it contained a 4L60E segment, but I decided to go ahead and flash it in anyways just to see how the engine would run. If it seemed like a good start I was going to try a little harder to find a 4L80E segment for it. It barely ran though, so I guess I'll start with a virgin 5.3 cal.
OK I didnt know if this was for your Toyota mud truck that you talked about a while ago.
Id definitely use the OS Joe posted (I always forget the exact OS number) with stock 5.3 values and a 80E trans segment. Can you post up the current tune that you have from the local tuner? If its ok of course. Not sure what can really be done without being able to AutoVE and tune spark, sounds like a mail order tune might be your best bet.
Will post it up tomorrow. It was a tune that a friend of a friend did on an LS1/ Radix car. In other words it wasn't for my truck at all. The thing runs pretty good, but it just feels like a dog. I know WOT PE AFR is too rich and I think it can take some more timing. I'm just not sure where to start since AutoVE is kinda out of the question. I want to learn this so bad, but I think it'll have to wait until someday when I build a street LSx powered vehicle. For now I'm afraid I'll have to pay a dyno shop. Unfortunately I don't know of any local that are top notch. There are plenty of them around but they don't seem to want to elaborate on what their procedures are. So I'm not sure who can build me the "perfect" tune.
I can do SOME street driving, but very little. Other than that I have a 50ft. dirt hill that I can and do raise hell up, spinning tires. Thats about all I can do.
Here is the file I have been using since last year when I completed the powertrain swap. Do you guys have any suggestions on what to ask a local tuner to try and decide who can and will build me the best tune possible? I don't want to be a douche, but I don't wan't to pay someone $500+ to copy and paste, I can do that!:bad:
Basically you want the VE mapped for PT and WOT, or do you need only WOT...?
You may be able to calculate VE for PT range using MAF, MAP, RPM, DYNAIRTMP/IAT... see CALC.VE_Table.VE in attached file.
I hate sounding like such a half-ass, but WOT is my #1 concern. I will need a fairly stable idle and will occasionally use PT, but more or less the truck is for pure abuse, so a toggle switch throttle would be ok.
I feel like I'm still in way over my head even after a year of reading on this forum. I think its because I need to start with the basics... proper scan tool set-up, and AutoVE. But that brings up my whole problem... off-road only. Can't get much hands-on.
Sounds like a tuner with a dyno may be your best bet... there really isn't any cut/paste solution.
:)
I think so too. It won't be long and my boss' truck will be running again and I will have the opportunity to tune it. Since its a street truck I'll be able to take it from the beginning and become familiar with the VE table. I look forward to it.
Are you thinking tune your boss' truck to practice AutoVE, spark tuning, etc then apply the concepts to your dirt rig? Sounds like a great idea to me!Quote:

Then later on if I make any more changes to mine I might be able to handle the calibration work.
Thank you guys so much for your time!

Got an appointment at the dyno shop Saturday morning. I pray he can find some power in it! I'll let you guys know it turns out.
Post dyno results... get the shop to include AFR/lambda in the HP/TQ graphs... (and any other info).
Will the dyno shop be using EFILive...?
No EFILive:bad:. I'll post it when its done. Thanks for keeping an eye out for me!
I have a new question. When tuning WOT A4 shift points, is there a way to set it up to shift by engine RPM only? Can I set D0910, D0915, and D0920 to unreasonable values and force the PCM to use only D0940,D0945, and D0950? Also for manual hold, I assume I can set D0913 and related so that in manual 1 and 2 the PCM will never command an upshift.
To trigger a WOT upshift, both the WOT MPH and WOT RPM have to be met...
if you set the WOT MPH to a lower value, then the WOT upshift will trigger on the WOT RPM...
e.g. if D0940 is 6000 rpm and this equals 40 mph, then set D0910 to say 30 mph.
To always hold manual 1st, set:
- D0913 to max,
- D0918 to max.
To always hold manual 2nd, set:
- D0914 to zero,
- D0919 to max.
Thanks, makes perfect sense. My truck did not get tuned Saturday. Hauled it out there got everything set up and strapped down, then the Dyno jet computer would not power up. I left it there, maybe get tuned thurs.
