Moving old Holden Tune parameters to new operating system

[68problemchild]

Hello All.

I have an operating system (Holden) originally programmed in 2010 with an E38 and T42. This was one of the initial matings of the E38 (todays motor is an LSX 376 crate motor) system using a 4L70E tranny.

After much effort from you all, this was working and performed well for about 6 years.

Recently the computer failed and I put in a new E38 and T42 for a 4 speed from Speartech. It has their stock tune. Since my tune and shifts were all pretty much perfect, I am trying to move the data from the old Holden operating system to todays op systems. (I got the computers today)

The software cannot "compare" the tunes since they are different operating systems.

Can anyone help move the basic tune data from one op system to the next? Is this doable? I hate to start from scratch.

Thanks so much in advance your input and ideas!

Warmest regards,

You have to open 2 instances of the tunetool, one on your old file, the other on your new file...

then for each table, you have to manually copy-with-labels from the old, and past-with-labels to the new.


If you could generate a file with all zeros in it, you could then generate a script to write the differences from zero into your new file.

Thank you very much. For clarification, I select and copy with labels the "description tab" or the "value tab"? I then paste into the new OS tune matching table? That is it?

Appreciate all the assistance for newbie here.


In the alternative, I know this setup is relatively common now.

Anyone have an LSX 376 (Iron not aluminum) E38 Crate tune for OS 12617631 and or
4L70E T42 OS 24239927?

What is the original Holden OS for ECM and TCM? Some items may be applicable, some not.

...

for lists of parameters, yes on the Description header immediately above each list.

For 2D and 3D tables, click in upper left blank tile (so the whole table/surface highlights), go rightclick->Copy-with-Labels.

What Joe said Pat, but not knowing what you have in the 12612381 OS, i.e. which areas are revised, best to leave the 12617631 idle & ETC area etc alone. At least initially. As they are different stock/from the factory.

Hard to know really without seeing them.

Hey Ian, how're you doing...

Good thanks Joe! You? Good winter there in So Cal?

Yes, good thanks, we only had near freezing temperature only one night; it has been warm enough to wear shorts/tshirt during daytime. And it rained a lot so now we're out of drought conditions.
