ISO gen3 ls tuning advise

Having issues trying to tune new set up. My experience is limited, I will try to explain as best as possible. I have a 1987 rx7 with a 2004 6.0 lq9 with a stage 3 btr cam. It is mated to a manual ar5 transmission. The electronic throttle valve is a 2004 along with the tac module and pedal all from a 2004 silverado.

From what I have read and tried I believe I'm having issues with my silverado tune because it is from an automatic transmission. With the speed sensor unplugged I can drive it with good power bun no drivability, it stalls during down shifting even with dfco parameters disabled. With speed sensor connected it is hugely reduced in power and still has stalling problems, even with idle increased and spark timing modified for cam.

I have tried a 2004 corvette manual trans tune but quickly learned that the truck ITV setup will not respond properly. So then I attempted segment swapping using ls droid. I used the corvette bin file and swapped a 2004 escalade engine and systems segments over. Unfortunately the throttle still responds as it did with the stock corvette tune. I'm using tunerpro to tune. Last year I had a stock 2004 5.3 and was able to get it working well enough to drive with the manual trans but it still had lots of drivebility issues. With the cam in the 6.0 it is nearly impossible to drive.

If someone could give me some advice or point me in the right direction or even better send me a base tune that I could start with. I'm using 12587603 bin files. Thanks!

Maybe try using universal patcher for segment swap, or you can with U/P compare tables of different OS's and copy everything over to a manual bin? I think if your tune is somewhat close, I would try using U/p to seg swap.

I would swap trans and trans diag

Thanks for the advise, I will try this out later today. As far as my tune being close, probably not. I'm just using base files I've found on this site to segment swap and will build from there. I will post my results. Thanks again

If you could post up the bin you used that had good throttle response, I could swap one for you to try if I get a chance.

If you could do that for me it would greatly appreciated. Attached is the stock 6.0 lq9 tune that was working well with my throttle setup. From there I should be able to get it tuned. Thanks Ralmo94!

I just downloaded that bin, and was able to swap a manual segment to it.

To Segment Swap with U/P
Utilities > Patcher
Original File - Select the one with the engine cal you want to use
Swap Segments
Select segment to swap [ trans cal ]
Extract from File [ file with segment you want to swap in ]
Apply
Extract from file [trans diag ]
Apply
OK
Save Bin { give it a new name as [ Seg Swaped LQ9 Manual ] or something }

More Screen Shots

Side Note, Both Files Show stock Checksums in U/P

File with Manual Trans I used

1GCEC14X04Z123261_4_3_2WD_manual_(12587603)

From Same thread the Escalade bin is on

Perfect, if you could repost it I will give it a try hopefully tonight.

Ah, got it, thanks

The Manual Bin?
Here it is.

So I've tried swapping the manual and manual diag segments to the lq9 file, it was successful in the process but the result that it would not Rev past 1500 rpm with or without wheel speed. I have read about a simular experience on another post.
The next thing I tried was to swap the engine cal and engine diag segments to the manual bin. The result was a crank no start situation. The only change that was made aside from this was deleting the vats.

My question is can someone get me this file in .bin format 1GCEK14V14Z268035. It would be greatly appreciated as there seems to be a little more than just swapping the segments to get this combination to work. Thanks

I'll take a closer look when I get back to my laptop, maybe this evening

here is the one I swapped, if you post yours, i could see if is the same or not

the one with a 2 at the end of the file name I did some quessing to the differences between the escalade and the manual bin. looks like the manual bin wasn't a DBW.
Included is the log of changes from the first modified bin

Here are those files, the 2 bin files are the trans segment swaps and the word document is the engine seg swap. That's how I have it on my phone as I am at work rn.

Other file

I ran both bins through the difference tool in tuner pro, they BOTH are the same as the one I uploaded. That means they are the same file, even checksums are the same.
Are you Writing Entire? It doesn't make any sense that you have different results with two files that the only thing different is the file names.

OS Checksum 1: D2E8 [OK] Checksum2: F683 [stock]
EngineCal Checksum 1: D1A5 [OK] Checksum2: FDB0 [stock]
EngineDiag Checksum 1: 5414 [OK] Checksum2: 6939 [stock]
TransCal Checksum 1: 4F7E [OK] Checksum2: 7C9F [stock]
TransDiag Checksum 1: 452F [OK] Checksum2: 7DE2 [stock]
Fuel Checksum 1: EBD7 [OK] Checksum2: 1A7C [stock]
System Checksum 1: 21FF [OK] Checksum2: C7C2 [stock]
Speedometer Checksum 1: F11D [OK] Checksum2: 150D [stock]

Repeat: All 3 files, the two you uploaded, and the one I swapped, all have the same checksums.

I realize you are probably using a seperate speedometer, but have you logged to see how far off vehicle speed is?

I Know you said you have a cam, have you dialed in your VE tables yet? Are you using a MAF?

What are you using for VSS? how many pulses per revolution?

Thats all I can think of right now

I also downloaded a manual Colorado tune from HP repository, Suposidly with ar5 ?
it shows a 40 pulse per rev sensor

Doing some quick math with the help of google,

Stock tire size for 87 rx7

185/70-14 24.2 tall 834 r per mile
76 circumference

4.10 ratio Stock ratio ?

40 ppr ? found in colorodo hp tuner file

834 * 4.10 = 3419.4 trans revs per mile

3419.4 x 40 = 136776 vss pulses per mile

So i Made the changes to the attatched bin

Make sure you write entire

Any updates?

Yes, I've been meaning to post an update. The segment swap worked perfectly, the not reving past 1500 was an issue with the abuse management settings. I still have some surging issues. It idles fine but as soon as it sees about 2 mph even without touching the throttle it starts surging excessively then dies. I believe I still have a long road ahead of me figuring tuning out but having the segment swap done put me light years ahead. Thanks for your help!

Great. Does it go lean wen it surges, or is it something else.
Can you confirm vss sensor pulse count, gear ratio and tire size
