411 PCM into 1997 L31 truck

[hog]

Hello.

I and a few friends have come up with a conversion for the Vortec 350/305 1996-1999 GMC/Chev truck owners.

Take a 411 PCM from a 2001-2002 Chevrolet Express Van that was equipped with the 411 silverbodied PCM, swap to the dual 80 pin connectors, and flash the PCM with an 01-02 Express Van cal. file.

Advantages: No more 5800 rpm rev limit like there was with teh 1996-2000 "blackbox" 4 connector PCM's. No matter what tuning suite or Pro Tuner you use, you can enter the rev limiter fuel shutoff to 7000 rpm and the rev limit will be around 5800 rpm.
Another advantage is the ability to install a custom O/S for 2 or 3 BAR forced induction.

Currently I am using Tunercats OBD2 to tune my 1997 truck.

#1. My question is does HPTuners support the 2001-2002 L31 Vortec 350 GEN 1E equipped express Vans??
I see HPTuners supports the 01-06 5.7L workhorse, and the 01-02 5.3L V8 engine.
#2. Is there a 2 or 3 BAR custom O/S that my forced induction friends can use in their trucks with the 411 PCM?

Those of you who are interested, here is the link to our "blackbox" to 411 PCM swap.

Also here is a link to our Marine Intake manifold swap that allows larger conventional injectors to be used in the 1996-2002 L31 Vortec 350 and L30 Vortec 305 smallblock truck engines. Originally these engines come with a restrictive intake that comes with a 19 pph poppet style injector spider. Now I am running a 24 pph EV6 style injector which flows at 28.3 pph at the Vortecs 60psi of rail pressure.
With this intake, there is no more 400 crank hp power limit in our trucks. This intake swap is more of a bonus for the forced induction crowd, but I have noticed better power in the 4000-5800 rpm range on my stock longblock Vortec 350.

Thanks for your time and any help you can provide. If you have any questions, by all means, fire away. Us 1996-1999 SBC V8 Vortec guys can finally make some real power like you GEn 3/4 guys can.

Hopefully HPTuners can support our needs. If it does I can pass the info along and all my friends can use HPTuners for their tuning/scanning needs.

Try to read the pcm...it should read out but might not load...if it doesnt load send it to me at support at hptuners dot com and I should be able to get it supported. If it doesnt read send me a vcm suite infolog & I'll see what I can do.

I was able to down load & open a file from a 2002 GMC Savana van that had the 5.7 Vortec engine. The supported vehicle list incorrectly lists this vehicle as a Gen III engine. This is the thread were I posted the file.

I have a buddy that wants to tuning help with his 1997 1500, so will their be a possibility of support on the truck, or will there have to be a computer swap?

PCM swap, unless you go DST or GMT.

I was wondering if someone can email me the spreadsheet of the pinouts for the 96-97 to 411 swap I've been hearing about.

Thank you.

Has anyone confirmed that a 2 bar OS exists for the 0411 express calibrations?

[EC_Tune]

Doing one right now...

[twinturbo]

So, do I just add the 2 bar enhancement for the gen3 to the file?

[wheelerman420]

Are the v6 and v8 pcms the same? Just different calibration files? Im thinking about this swap, I have an extra v6 ecm lying around. I am a mechanic for a local shop, and i looked up part numbers for the ecm's and they all come back as a 12200411. Could it be possible that they are all the same hardware just different programming?

Yeah, be ready to use 4 credits. Be sure you KNOW EXACTLY what calibration file you are flashing. Also you will have to disable a few mil errors, and vats. Other than that you will be really happy with your end result, I was.

P.S. The newer style injectors also make a BIG difference if installd at the same time. Damn poppets! GMs biggest mistake.

giong to use TPI off of a 1986 Camaro with EV6 injectors
