So if I do the msd box and I try to use a dash out of a 2005 or so truck with all the gauges still work without the factory ecu

 

Why would you want a dash that is vin locked to the pcm you will also need the bcm

 

Well what I want to do is take the interior out of a new truck and like the wiring harness that way I can have power windows auto lights interior lights dual climate controll a/c etc
Basically I want it to look like a 72 blazer on the outside but be a 2008 or newer truck on the inside.

 

well, thats the hard way to do it but thats up to you.

 

I can buy a new ecu for 80 bucks it's doesn't have a flash on it is there anyway to flash it myself or does a dealer have to do it

 

dealer or 600 dollar software or spend less then 600 and get a fully built megasquirt 2 and buy a used msd 6010 box and the software is free for both and you can tune it your self with out all the extra bs to worry about like traction control etc.

 

That's sounds like a better way to go my only question is by deleting the factory ecu will I lose anything as far as the dash goes

 

What software out there allows u to program factory computers

 

EFILIVE and I have the ability to flash it for you. PM me if your interested

 

Ok cool do if I send u the ecu u can flash it and send it back
