New to efilive doing PCM swap have a couple questions

[Cool28]

Ok so on the ECM swap says download your current program off the ECM. Where do I go and do that? I did the read PCM calibration in tune tool was that the right thing to do? After that do I have to clear the data in the new 0411 ECM or just copy it over? If someone could link me a post about it cause I couldn't find anything on search odd enough

[joecar]

Yes, from the tunetool, read the calibration and save it to file.

What PCM are you swapping from...?

[Cool28]

I'm swaping from a ls1a ECM to a 0411 ecm.

[Cool28]

Also since I have unlimited 98 tuning I take my vin from the ls1a ECM wouldn't count against my vin license amount?

[Taz]

EFILive tuning licences are not VIN dependent, they are controller dependent. You may tune as many LS1-A PCMs as you like - free of charge. You are now swaping to an LS1-B PCM - this will require a tuning licence - irrelevent of the VIN in the LS1-B PCM.

Ah ok thanks

[joecar]

You will have to copy tables from the LS1A to the LS1B...

open two instances of the tunetool, and use copy-with-labels and paste-with-labels to get the columns/rows aligned correctly; there will be a few tables that don't fit; when done copying tables, save the LS1B file and do a full flash;

a good LS1B file to use is the 12212156 file with the trans segment matching your actual trans.

[Cool28]

Ok so if I used the12212156 file with a 4l80e trans segment and just copy the rest of the tables not segments over on all the rest of the stuff correct? I'm running a 4l80 on 98 that why the ECM upgrade

[Cool28]

And a changed segment for the fuel guage

[Cool28]

Well ok the ls1a has alot less tables then the ls1b. Do I just leave that stuff in there as is then?

[joecar]

Yes, just leave the tables that can't be copied; copy all the other tables.

[Cool28]

ok thank you :)

[Cool28]

Ok been looking at the files and starting to get a feel for it. I have a tune that is a 98 -02 tune with the segment in it. Now can I just upload that into the new ECM and call it done or is there a reason I'm not seeing to upload my stock tune first then upload the 98-02 tune?

Right now I'm adjusting shift point of this 4l80e segment I swapped in.

[joecar]

You mean a 98->02 conversion tune (based on the 02 file, with 98 tables copied in)...?

Your stock 98 tune will not upload into the 0411 PCM; so just simply full flash the 98->02 conversion tune into the 0411 PCM.

[Cool28]

Ok yep that's what I was wondering thanks again. This tuning stuff pretty fun. Just have to figure out what I'm doing lol

[joecar]

Follow the links in my sig...

[Cool28]

Well programmed the new ECM. Put the 4l80 segment in from a express van and changed the shift times and stuff like that. Only thing in scan tool it shows 4wd is that going to be a problem?
