Help please....
I have a 97 chevy truck with 5.7 4l60e...
I put a 355 in with flat top pistons and aggresive cam...
I ordered hp tuners allready...
I am fixin to buy a 411 pcm for my truck from this ebay post
http://cgi.ebay.com/ebaymotors/Expre...Q5fAccessories
If i get them to flash it for a 2002 express van file and writ emy 97's vin number in.
Will i still have to use 4 credits to start tunein or only 2 ???
Any help will be very much apperiated..
If you have them flash in a 2002 file with a 97 vin you won't be able to license the pcm with our software as our licensing must see a valid vin/os pair which that would not be.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
so what would u suggest i do then???
Have them flash it with the calibration file from a 97???
I have another 411 pcm i picked up from the scrap yard today?
But it wasnt in a car at the time, it was soposed to be out of a 2002 express van , but that doesnt mean it is...
It is a serv. no. 12200411 dfnn
hdw no. 09386530
What should i do?
This is all new to me....
Never tuned before but looking forward to learning..
pcm would need to be flashed with a valid vin/os pair according to gm http://tis2web.service.gm.com/tis2web
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
i missed some numbers on the vin...
its 2GCEC19R4V1264774
What am i sopposed to do with that site in that link u sent?
Wouldnt it work?
They say they flash the proper calibration programed to the specific car.
This auction is for one 12200411 Ecm that will arrive at your door ready to install with the proper calibration programed to your specific vehical. This ECM will fit the follwing application:
2001 - 2002 CHEVROLET EXPRESS 1500 V6 4.3L 262cid GAS FI N Engine VIN = W
2001 - 2002 CHEVROLET EXPRESS 1500 V8 5.0L 305cid GAS FI N Engine VIN = M
2001 - 2002 CHEVROLET EXPRESS 1500 V8 5.7L 350cid GAS FI N Engine VIN = R
2001 - 2002 CHEVROLET EXPRESS 2500 V6 4.3L 262cid GAS FI N Engine VIN = W
2001 - 2002 CHEVROLET EXPRESS 2500 V8 5.0L 305cid GAS FI N Engine VIN = M
2001 - 2002 CHEVROLET EXPRESS 2500 V8 5.7L 350cid BI-FUEL Engine VIN = R
2001 - 2002 CHEVROLET EXPRESS 2500 V8 5.7L 350cid GAS FI N Engine VIN = R
2001 - 2002 CHEVROLET EXPRESS 3500 V8 5.7L 350cid GAS FI N Engine VIN = R
2001 - 2002 CHEVROLET EXPRESS 3500 V8 8.1L 496cid GAS FI N Engine VIN = G
******GM installed this 12200411 ECM in all of the above applications. This was possible because each of these models received their specific programming from the factory. In other words, you can't simply swap a used ECM from one vehicle to the next. We are a licensed user of the same GM software that a GM garage would use to reprogram and update your computer. With your purchase we will reprogram the ECM, with the latest software updates available from GM, to your specific vehicle using your VIN (vehicle identification number).
or am i missing somthing?
How are all the other people installing 411 pcms in their pre 2000 vortec trucks?
They would be using a valid vin/os pair ie 2002 silverado vin with a 2002 silverado operating system
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
but a 2002 silverado operating system wont run a 97 style vortec setup???
Am i wrong about that?
so what do i need to do to start geting stuff moving??
Leave the vin on the express van computer alone.
It was just an example, same pcm either way.Originally Posted by rmitch1902

I might just be dense about this, but....
What exactly do i need to start tuning my 97 chevy 1500 then....
I allready have hptuners on the way...
will all i need is a , 2000-2002 computer out of a express van...
And leave the vin alone so it matches the os..?
They have the same engine and trans in the express vans as in my truck...
Your help is appreciated...
leave the vin for the express van alone. plug in wires correctly and enjoy
I'm doing this swap this coming weekend. I'll be able to help after I do the swap. Been researching a great bit and got everything I need to do it. If your getting your ecm from spareecm on ebay they will include connectors for 35 and a few extra ends. good luck
i went and got a ecm and connectors from a junkyard saturday.
I have hp tuners on the way..
So all i need to do is get a spreedsheet of the pinouts now ..
Im doing this swap too same truck as yours. I have hp tuners, and ordered the pcm from spare ecm off ebay. should be here tomorrow. If you pm lextech on the full size chevy forum he will email you a spreadsheet. Let me know of any progress you make.
I just did the swap on a 454 Truck . Having Tuning issues with it now , will post as tune improves.
i just purchased the pro version of the software and am interested in adding the wide band o2 sensor, i know it goes to the green plug on the side, what are the pinouts for that plug and what o2 sensor gets the best reviews?? ty
hey man i see you are having troubles i did this swap and you need the tuning file from an 02 express or savana with a 5.7l vortec and the proper transmission code 4l60e or 4l80e last i looked one with a 4l60e was not listed in the repository and being a mechanic i flashed mine using gm software on my otc pegisys and modified from there if you need the base program installed go to a local shop and have it flashed after you install the pcm
