Sorry, I am only familiar with EFI Live and a little bit with HPTuners.

In EFI Live you can tell it which platforum you have as well as select which type of throttle body under the options.

 

Too bad the jet one isnt that intuitive...

May have to break down and spend 600 plus bucks and get me efi live

 

I didn't see the ability to do that in HPT.

I could be wrong as I am not as familiar with it.

I have never tried to change it either.

I know if you use a Van Operating system and you have the correct computer it should function.

The Vans had DBC from the factory all the way up to 07 from what I read.

 

So who's done this.

 

Ok I have done this, had to learn myself and lt1swap.com was very helpful as well. As long as your pcm has the IAC driver chip it is a simple switch in system options to turn it on then you add the 7 wires 3 for tps and 4 for iac and good to go. whatever platform your pcm was out of then ETC should be set to 1 if it is DBW then you change it to 0 and tps and iac will work. All my trucks are swaps and all DBC

 

I have to locate a pcm. Pretty sure mine doesn't support it. It I have access to some 04 express van ones so one should work. I need to check the service number on mine. I've been reading on lt1swap.

 

what tables in the idle tab need to be changed. I have a tune file from a DBC 5.3. Do I need to copy that data? If so how much of it?

 

tables should be the same because the air needed for idle is the same

 

The IAC reset position is 0
and the park position airflow table is 0
does this need to be changed?

 

would I be able to do the sway if I had engine wiring harness for DBC motor and intake and tb and ecm ?
