I have a 03 crew cab s10 with the 4.3L v6 and 4L60e. The engine is mostly stock, all I have done is a drop in K&N filter, and shaved the throttle blade. The truck has a small lift and bigger tires. I...

I think I understood most of that, but without a drawing I would have a hell of a time trying to build it, lol.

Thanks for the help though.

Any chance that the PCM has an output that changes...

I need to make something that will close a relay only when the vehicle is stopped. This needs to be independent of if the truck is in gear or the brakes are on or any of that. I was thinking of...

It won't let me view this because I'm not a member. And I don't speak french so I can't figure it out. Can someone that has the info post it in here for the rest of us. Thanks

Did those injector values work for you? I have the same injectors in my 7.4 and I'm trying to get it dialed in.

Thanks,

I have a 99 Chevy truck with the 7.4L BBC. I upgraded the stock 22# injectors with 28# injectors from a 01 Z28.

I grabbed a stock tune for a 01 Z28 from the tune repository and started making the...

Thanks, yes I am a customer, just have to get my serial number when I get home tonight.

This may be a dumb question but how do I get to this repository?

Just curious, are you changing the tune each time to do that or do you have a switch to manualy lock / unlock the TCC?

Wow, we really hijacked this guys thread, lol.

If you actualy use your truck to tow or haul alot dont bother with the 6.0, no passing power and the milage will be similar to the 350. If you use...

Thier site doesn't really answer any questions. From what I can tell it looks like they just sell custom tuned chips.

I guess I'm more interested in finding a way to tune a 6.5TD through the OBDII...

I just got the truck last year, with 216k on the clock with almost everything being factory original on the truck. The owner had the recept for every oil change and service he ever had done since he...

By that you mean HPT can tune a 6.5TD or that you have something else that can tune it?

You can get an accelerometer at radio shack fairly cheep, I think they are ment to go into laptops or something like that, you could hook it up as an external sensor and added to the spread sheets...

Just though of something else, does the 99 PCM have the capablity to do a tow/haul or performance button or is that something I would need the 0411 PCM to get? The truck doesn't have the button from...

I have a 99 K3500 with the vortec 454 and 4L80e. I use this truck to snowplow, pull a car trailer, haul stuff and I also take it out and have fun with it. I would like to remove the TM because it...

I'm installing a new distributor in my truck and I'm wondering if there is a way to use the VCM scanner to set it to the correct possition so the timing is right?

I know at the shop they use a...

Ok, sounds just like swapping over the 96-00 vortec 350 to the 0411 as far as the wiring goes.

But once you get into the PCM with the express van code, I don't think it will have OHV 7.4L on the...

What is all involved in swapping over to the 0411 PCM? Would it matter that there was never a 454 / 4L80e that ran that pcm?
