Tuner Pro XDF 1999-2000 F Body + Y Body

[john h]

Been working on this for awhile now. It is still a work in progress. Checksums seem to be good. Just have not had a chance to test on a vehicle yet. Use at your own risk. Let me know if something does not work.

Hi,

I just checked a .BIN i have for 1290003 and the VATS is reporting its off with your XDF, but EFI Live says its on class2.
Also a lot of the values on scalars is wrong too.
First example I can see is Fan type =77 and everything after that =0

OS Support
1290003
9360361
9381344

9360361 (1999) and 9381344 (2000) have their respective parameters at the same hex address. 1290003 is an EFILive COS for 12225074 (used by Holden from 2001 through 2004), and is completely different.

The XDF may support 9360361 and 9381344, but cannot support 1290003.

[john h]

Corrected supported OS info. I read some bad info. Can anyone confirm that the xdf will work with the 1999-2001 LS1 Holden .bin file. I could not find one.

[LRT]

If you based your work on the XDF on 9360361 and 9381344 (which are essentially the same), then these are the only two operating systems that are compatible with your XDF.

As far as your question about 1999 to 2001 Holden operating systems, these used several operating systems, and your XDF is only compatible with 9360361 and 9381344.

[john h]

I did base it on those OS's. The reason I ask about the Holden cars is Tuner CATS states that there definition file for the 1999-2001 LS1 cars also works with 1999-2001 Holden. They are not specific on what models. Most likely LS1 and the same OS numbers.

[LRT]

When working with, or creating an XDF, it is more accurate to think in terms of the operating system, rather than just the vehicle.

When it comes to Holden, sometimes they used the same operating system as North American vehicles, and sometimes they did their own thing.

Some 2000 Holdens used operating system 9381344, which should be compatible with your XDF.

[evilstuie]

Yeah, so far I've had a couple of weird OS's from Holden PCMs.
I've now got a Holden LS1 MAFless tune with COS3 1290003 unlocked that I'll post up this afternoon.
I wish I had the XDF for this one as at the moment I was told it had VATS removed but when I loaded the .BIN in EFI Live v7.5 it said VATS was still on Class-2, plus its for a manual and I need an Auto 4L60E.

I don't suppose anyone is able to modify it and send back a copy with the changes once I upload?

[john h]

That's not an easy task. I had to find certain parameters in this xdf that were not in tuner cats but are in other tuner software. Lot of it is trial and error. Might be easier to just buy efi live or pay someone to do it.

Very true.

Writing a good quality XDF takes hundreds of hours of work.

I don't know why you would choose to run an EFILive COS, as you can't adjust any parameters using Tunerpro without a matching XDF.

Post the bin if you want. I can swap in the auto trans segments and disable VATS.

[evilstuie]

Hey LRT.

Here it is.
If you're able to remove VATS, segment swap the 4L60E transmission in and maybe even set the diff ratio to 2.73 and maybe set the bank assignments to SBC order instead of LS1 that would be the best birthday present ever! :)
But even just the first 2 would be awesome and get me in the zone for starting the car up.

Thanks.

[LRT]

Attached is the BIN that you posted, which has been converted to a 4L60E (from a 6 speed manual), VATS has been disabled, and the Cylinder Bank Assignments altered as per EFI Connections instructions for use with a SBC.

[LRT]

and maybe even set the diff ratio to 2.73

There is a bit more to it than that. You would need your gear ratio and tire diameter to calculate VSS and TOSS pulses. Then you would need to adjust a couple of dozen transmission tables (shift and TCC).

[evilstuie]

Legendary!

Thanks mate. I'll try it out now.
Gear ratio is 2.73 with 225/60/15" wheels, but I'll get an exact measurement. I can give you the .BIN file of the car the transmission was out of if you can just swap those in which would be fine.
If I don't get this OS working I'll go back to the other OS, and mayeb I can throw you a few bucks through paypal just to set up the basics so I can get it to a shop to dyno tune it? :)

[evilstuie]

Just plugged it in to the car and nothing. Quickly just checked and I thinks its just a fuse, gotta head out for birthday lunch with the missus and then will figure out whats going on and let you know, fingers crossed tho. Thanks again :)

[evilstuie]

Hi LRT,
It is so close to starting, but just not quite there.

I'm gonna try adjusting the dizzy slightly to see if I can correct it, but is it possible for you to copy the L31 spark tables from this .BIN into my one?
Someone mentioned the SBC needs a bit more timing than the LS1.

[evilstuie]

It runs it runs it runs!!!!!!!

[evilstuie]

Checked yesterday and the timing is pretty rough, and it looks to be sitting around 5degrees at start and then slowly climbs to around 20 as a apply throttle and the motor warms up. Does this need to be adjusted in the tune or by moving the distributor?

I had this response from one of the guys on thirdgen forums:


Timing table you are looking at 34-36 deg at wot, 36-38 cruise areas, and 25-26 ish idle. In 411, the table is based on grams airflow per cycle or so. A na motor typically sees .80 or so gram/cycle. I would have to double check my logs but the max value of 1.2 i hit at 3-4 psi boost by 3600-3800 rpm so i think na motors see .80-.90 and not much more. I'll confirm that later

In general stock ls1 timingtable could be used but add 3-4 deg to it in the higher rpm higher flow areas as a ls1 sees best power around 26-28 deg while a sbc typically is 34-36. Ls1 cruisetimingcould be used. Idle areas may need increased due to larger camAre you able to either drop the other spark tables in or adjust these on my tune LRT? :) :) :)

[LRT]

so I can get it to a shop to dyno tune it? :)

You originally asked for help to get the car running, so you could then take it somewhere to have it dyno tuned.

You chose to use an EFILive COS - for which there is no XDF available. Had you used 2001 operating system 12202088, then you could have used the only OBD2 XDF created, and used Tunerpro to adjust things in the tune.

It is not really a DIY (do-it-yourself) project, when you ask someone else to do the tuning for you.

Altering the spark tables, by working in the raw binary code, would be quite a bit of work. I don't think you realize the amount of time it would take to do what you are asking.

Hey mate, sorry I assumed you were using some other software so you could just copy and paste the tables into excel, make the changes by formula and paste back into the tune file. I didn't know you were editing the tune in hex.
I didn't choose the COS3, it was the OS that was on the 3rd PCM I'd bought to try and get the car running. I had the 1074 OS which had XDFs, but Dimented's LS1 Flash tool bricked them both when trying to change to a different OS, so I was stuck with what I got.

[evilstuie]

With COS3, it's a modified version of the 12225074 OS yes?Would there be much involved in modifying the XDF for this to work with COS3?

[LRT]

First, a couple of assumptions. That you already have an accurate XDF for 12225074, and that this XDF also correctly calculates the segment Checksums.

Then, you would need to determine which parameters in the XDF are no longer used by the COS, and delete these parameters from the XDF.

Then, you would need to determine which parameters in the XDF have been altered (rescaled or repurposed) by the COS, and adjust the definition of these parameters in the XDF.

Then, you would need to locate and define all of the new parameters in the calibration created by the COS, and add these new parameter definitions (flags / scalars / tables) to the XDF.

[babywag]

If it was me I'd remove the chip(s) and burn on a supported OS, then resolder them on.

Since you have multiple bricks, seems like logical way to get 'em all back to operational?

If you choose an OS with an .xdf tuning could then be DIY

[evilstuie]

Babywag,That was my initial plan, but the programmer I bought (TL866) didn't come with the right adapter, and the BDM programmer I bought was only for 16bit controllers not the 32bit Motorola chip so I lost the energy to continue.I might see if I can get the adaptor and give it a try.

My plan was to take the car to a tuner to put on the dyno, but that is going to cost me at minimum $1000AUD, which would be fine if that was it.But I need to have the motor properly run in and have it able to idle long enough to check things like thermo fans kicking in, check for oil leaks, and all that, otherwise I'll take it to the dyno, they'll spend a day trying to tune it and at the end of the day come back to me and say there's something wrong or the plugs are fouled or the motor cooked, and take my $1000 as well.With 1500rpm the timing sits around 25 and sounds really good, but at idle its jumping between -8 and 12 and cuts out without throttle.

[LRT]

My two cents, would be what Babywag suggested - move to a 2001 OS (12202088 or 12208322) and tune it yourself, using TunerPro and the XDF and Checksum Plug-in that I posted. Dimented24x7's flash tool will work with either of those OS.

Dyno tunes aren't cheap - typical prices here begin at $650, but you are usually closer to $1000 by the time all of the issues in a conversion project are addressed.

Hello i have posted this in wrong area > So i am looking for a XDF File for 1344 Os for a 4896 pcm out of a 2000 silverado with a 5.3l lm7 with a 4l60e m30 4x4 > Or question 2 is can i just flash 2088 ,or 3372, or some other 0411 OS that is close to my pcm ????? > Is 4896 pcm not worth hassle to just go pull a 0411 and be done

[B52Bombardier1]

From what I'm told, an 896 and a 0411 are virtually the same - both 512k byte PCM's. The only virtue in a 0411 is that it logs things slightly faster.

FLASH a different Os to it closet to what it is witch should be not hard to figure out

[B52Bombardier1]

Hello,

Yes - they both have red / blue connectors and the pin outs are the same. I have two 896 PCM's and a 0411 PCM and all three can . . . and are . . . running the same software load in each.

Yes - I would give you a copy of what I have in each but that wouldn't work for you because my setup is different than yours. Also, these are running a custom OS from HP Tuners and there is no matching and publicly available XDF for it.

And finally, some slick lawyer could someday say that I'm giving away HP Tuner intellectual property and I really don't need that hassle.

Rick

[bigbill0679]

Thank You For The offer but This is Just to learn more i have not done a 4896 at all,
and to be honest i pulled wiring dia. up on this truck too see if all was the same @ pcm .
So now i will Flash it tomorrow my bench harness is @ my shop
Bought truck cheap it has rotter rear frame but i have a truck with light roll over damage perfect frame
good package then sell sell sell.
Again THANK YOU B52Bombardier and everyone else who commented
