I'm looking to do 411 swap but can only find 5.3 silverado ECM at local yard they keep saying there interchangeable what's the best route to get the express van tune onto the silverado ECM thanks

[CalEditor@pcmcalibrators]

all of the 0411 are the same. The van calibration has the same OS as a Vette or a Astro van. You need a truck calibration for a truck and a van calibration for a van. You need an S10 calibration in an S10. If you put a van calibration in a Camaro you have issues.

I. Don't mean to ask stupid ? But just so I under stand. Correctly use the truck ECM an copy past the values for the van engine sence it's a 5.3 going to a 97 5.7 I'm doing the 411 swap in a 97 silverado

[CalEditor@pcmcalibrators]

I would not use the van calibration at all. The van calibration would be all wrong and you would need to do a bunch of work arounds to fix/patch it up to work in a truck.
I would use a 5.7L 0411 out of a truck and be done with it.

They don't make any 5.7 411 in a truck that's the problem they say to use 01-02 express van braise it uses the same 5.7 vortec an 4l60e an uses a 411 ECM but if u no were I can get a stock 411 with a 5.7 I'm Intrested then I an start re pinning thanks

Strange I even have a 2003 5.7L truck calibration how could that be. Oh wait you don't have that facts

GMT-400 was built from 1988 to 2006 --> YES 2006, but they did not have 5.7 in them in 2006 they had 8.1L and they were 15,000 lbs trucks. Mexico Only

The 2004 GMT -400 used the 8.1L and the 2004 Chevy NPR used the Gen III engine. The NPR is the Izusu tilt cab. The landscaper vehicle of choise

In 2003 the NPR used the 5.7L with an 0411. The GMT-400 had an 8.1L

In 2002 to NPR had the 5.7L and the GMT-400 had the 8.1L or the 6.5L ---> yes they still used the 6.5L in Mexico in 2002.

use a express van tune or gmc savanna tune for the 96-99 vortec trucks with a 5.7L. You 4wd low will not up shift but other then that its a simple swap.

[wyochimneysweep]

calediter could you add 4wd ratio tables to a gmc savanna file?

Why would you use an Express van calibration?
You have 4000 parameters in the calibration most of them you can not see. Why would you just not run a truck calibration in a truck?

As far as a 0411 swap in on a 5.0 or 5.7L GMT-400 you could use a 4.3L calibration and build it out. That would take just a few minutes to do.

Were do we get these files than

Also what is missing or make it not shod in 4low

I would need to look over a calibration

We have 2500 calibration files in our repository. I give them out as needed. I will post a few up later tonight. I am working out an issue in a tune currently

[1badcj]

Thanks

[CalEditor@pcmcalibrators]

Thanks

These are the same file. I just changed the year so it will show a workhorse vs a Holden. It is actually neither

[1badcj]

That's for a non Ls 5.7

[CalEditor@pcmcalibrators]

That's for a non Ls 5.7

Look at the tach settings
The calibration is a HVS 5.7L
High Voltage Switch (HVS) -- It has a distributor

[1badcj]

Perfect thanks

[wyochimneysweep]

I don't see anything for 4wd settings in the file?
