Tuning Freedom On The Cheap, 0411 PCM Swap, LS PCM On A SBC GMT/400 OBS Chevy Truck.
Вставка
- Опубліковано 24 сер 2024
- Being honest..... the black box computer that runs these trucks from the factory sucks as far as freedom to tune and get the maximum performance out of your OBS Chevy Truck, even SBC LT1s can do this swap. The Holley is definitely superior, we all know this. Until things change for me I'm going to be keeping budget in mind, even when things do change I'm probably still going to be a budget bang for buck guy. Hopefully this video helps so you guys don't make the same mistake I did.

Glad you was able to figure out how to make it run better.
I would have done the same thing and for got all about the EGR valve. Great video 👍🏾
Appreciate it my dude. I’m gonna put it on the dyno In a couple weeks then put the 0411 with a high octane tune in it to see how much HP it can add.
@@RCSmith90 can't wait to see that video 👍🏾
The wires in the little black terminal is a ground used only on a 96-97 black box
Yeah it’s odd. It’s almost like it grounds its self. I found a diagram that showed the wire on pin loops around like a foot and a half then goes to the other pin in the same harness.
Was going to add that little point myself lol. Yup
Woah woah woah dublins EKG bible? Nice!
@@1Ezk GOOOD EYE DUDE!! Good eye. 👁️
Video I was waiting for .
If you need more detail I can send you the link to one of the guys that gets a little more in detail.
Also I’m going to take the truck to get Dyno’d as is, then swap in the other pcm you see at the end. It has a high octain tune. Then dyno it again to see what it does.
@@RCSmith90 can’t wait
Remove your damn buzzer box! Just unplug it and toss.
😂😂😂 good idea
I've been trying to email lextech for a pin out spreadsheet where did you get yours please respond
@@croomsracingengines9265 I got mine from Lextech. Do you have his actual email address?
How does the LS computer mount in the black box mount
It gets flipped upside down, then it it’s in place. You can trim the edges with a rotors tool where the computer mounts into to get it to sit right side up. Only thing with that is you have to extend a few of the wires by a couple inches. I’ll be doing that eventually.
Great video! Doing the same swap on my 97 and was also womdering what egr block off kit was that?
Thanks man! Appreciate it. The original link I had doesn’t work anymore. But I found it

I’m in the process of doing this swap. I also opt to send the PCM to lextech for a startup tune. Only thing I don’t quite get is the trans range switch, did you have to mess with that?
I didn’t have to mess with that as far as I know. I don’t believe Lextech mentioned anything about that in my application.
Glad you’re doing this swap too! Well worth the benefits.
Hey man, did the 4 colored connectors off your black box labeled C1,C2 and so forth? I can’t seem to find the markings to know which is C1,C2,C3&C4 (Blue,Red,White,Black)

(Black Box Connectors)
C1 Blue
C2 Red
C3 White
C4 Black
I appreciate it!!
@@carlomendoza8588 no problem man.
Does he still offer the spread sheets? Do you have a contact for him?
Yeah he does. I can put his email here. As soon as you have it let me know so I can delete it. Don’t want to many people getting a hold of it to protect him.
Ok awesome!
Got it I appreciate it!
@@kjsdfhjlkashf no problem
@@RCSmith90 I'd like to get with him about deleting the black box from a 97 Sonoma. I have HP tuners so not having to send out a pcm to have it updated would be nice.
Plz
Where can I find his email?
@@RCSmith90 ok I got it
@@RCSmith90 thank you
@@DJHunt89 no problem
