Thanks.

That's what I have for my crank and cam signals currently.
This Express Van tune is going to work to get it started. Just need to put some miles on data logging and dialing in.

Thanks.
Yep, found that.

Also, research has me at now using an 03 Express Van tune as GM still has it as DBC with the CNP.

I got All Data diagrams for the 03 as well, so I believe I'm good to...

Thanks.

Didn't understand what you were saying.
So the computer uses that table to isolate the issue?
Not to tell the coils when to throw a spark?

I was going thru pin outs for 02 F body because I read of guys were using that OS, and hit a snag with the front VSS. I'm running a 4L80e. The F bodies must have only come with 4L60e's?

I guess...

Thanks.

I was looking at the firing order of the Express Van tune and seen old school firing order.
I have a 5.3 swap in my El Camino and didn't even realize the firing orders had changed after...

Thanks.

Really? There is a place to type?
Never seen a typing window before.

I know how to click stuff.
I found system and firing order. Looks easy enough to change that.
I also found ETC...

Thanks.

8.1 has a different firing order, but that is easy to change, I think?
Just use HP Tuners to change it?

I found some tables for the 36 LB GTP injectors I have, so just copy and paste...

Thanks. Will pick a tune that I can find a good diagram for as I believe this to be of utmost importance.
Will need to be a drive by cable system.

Dizzy is now a cam sensor, 1X, and I have a 24X...

I don't think so any 454's on the 0411. I have a 1998 Vortec 454 I'm stroking and that came with a dizzy, not coils for every spark plug. I got an 0411 ECM and harness currently from an 01 Express...

I have a 496 block coming from the machine shop soon. I will assemble it and spark her up on the stand.
I have 24x crank reluctor and 1x cam sensors.

My 0411 is from an Express Van with only 1...

Thanks.

How is it down there in the States? Just walk into any computer store and buy a piece of air straightener?

Under 100 bucks? Wow. Ain't gonna happen up here.

Thanks.

That's a nice one.

Thanks.

I got the welder.

Thanks.

Too poor to spend 4 bills for the complete unit. It's double the cost up here, north of the border. I'm sure I can make up the same thing.
Does the one you linked have an air straightener...

Thanks.

These both come with just the card I see.
That's checking Rock Auto's site for Corvettes with the LS3 and LS7.

I'm working on some intake tube plumbing for my BBC 496 stroker. My throttle body is 90 mm and accepts a 4" size inlet tube.
I need a MAF sensor to finish the plumbing.
My PCM is an Express Van...

I cannot open a tune other than what's in my computer's files.

I go to defaults and for .hpt files, it tells me there is no installed app in my computer.

I updated to latest version and still...

How you enjoying the learning curve?

Be careful with spark advance if you change the tune. I developed piston slap after going a bit too extreme.
Or perhaps the 5.3 gets piston slap commonly?...

My 5.3 (DBW) 2004 is stalling out in the last two days on start up and once after driving a few minutes.
I noticed my wide band reading 10:1.
I scanned this morning until it stalled. Fuel trims...

I know this is not supported, so just want to post the problem and see what smarter minds here can figure out.

About 6 weeks ago, driving on the highway, an exhaust pipe broke off and I had to...

I guess I'll have to answer my own question/issue.
I found a thread from a couple years back about the same thing.
...

WT? :confused:
I just noticed the TCC shows applied in 1st as soon as I take off.
Does the scanner just say applied even if it it's not?

Thanks.
Will check it out.

Thanks. My dyno program comes out at 375 ft lbs and 359 HP.

How about the torque management. What does that actually do?

Thanks. I find it can't even spin the tires. There is a lot of power there, but won't cut loose. What can be done for that?

The car is 3500 LBS with 3.73:1 posi.
