Yep that was the issue. So glad it was simple!

It has been about a year since I've used my interface, but I got it out today and am having an issue. My laptop makes a noise to let me know it's plugged in and the interface's power light is on. ...

I know they're suppose to constantly be changing, but I feel mine are acting too erratically. No DTC's are showing. The engine is a 350 Vortec running a 411 pcm in a 2000 Blazer. What would cause...

I have a 5.7 Vortec running a 411 PCM and a 2002 Chevy Express van tune in a 2000 Chevy Blazer. I have a flat response(2 wire) knock sensor and am wondering which detection mode it should be in,...

So what do you suggest I do?

Correct. Why does it not make sense?

Yes.


I don't know on that one.


Correct. It's that I've been told by a bunch of people that the NV3500's aren't a trans that you want to be too hard on. If it was a auto or a t56 then I...

Yes you're correct. I found a guy that has almost the identical setup only with a near stock exhaust and stock manifolds, I think his dyno sheet showed him making about 50hp more than me. I figured...

Dyno showed 229rwhp.

I have a 350 Vortec in my 00 Blazer. The tune is just about right. I took it to a dyno tuner and he said he didn't really have to change anything, but I still think I should be getting more hp and...

Thank you. It says I do not have a license for this file. Why is that? I even just pulled the tune that I put on my PCM and it says I do not have the license for it.

I installed a new hard drive on my laptop and when I installed the suite and opened it up for the first time it's asking for my application key. Where can I find this at?

also how do I tell if it's tuned for the resonant or flat response knock sensor? As stated it needs to be for the LS1, single wire.

Thought I'd bump this. I'm still having the no knock reading problem. Since the 350 Vortec sensor was under warranty I went and picked up another one. I'm getting a reading from it, but the PCM...

I just checked the wire from the pcm to the knock sensor connector (since I had to extend it for the swap) and it's good. Put a ground to the knock sensor and banged around the engine. No reading...

Well I tried putting the wire into #9 and still got the same outcome.

Thank you so much for clearing that up! Now how can I find out if mine is calibrated for resonant or flat response? Do I just need to try it in C1 Pin 9 or is that too dangerous to attempt?

I was just told by a guy that did the same exact swap as me (only he has a 96 model Blazer) that he has his knock sensor wire plugged into C1 Blue 9 and he's getting a reading. He put it into C1...

Here's the current tune and matching log.


All I can tell you is that I have a 1 wire knock sensor. I seen that the 5.7 and 4.3 sensors are different so I got a 5.7, but no change. I'm...

I've tried various tunes and have yet to get a reading from my knock sensor in hp tuners. I've checked the wiring and all is good, the knock sensor is brand new too. I threw my old 4.3 knock sensor...

Yeah that was the problem, just had to turn the EGR back on

I have a 2000 S10 Blazer with a 350 Vortec and 411 PCM. I have a NGK AFX wideband and have it all hooked up, but am having problems getting it to read in the scanner. I have it hooked up to blue...

I was told this could be done and that there's a how to thread on here somewhere, but I cannot locate it. Can anyone help me out?

Well here's the story behind all of that... I called Jesse and explained exactly what I wanted which was the 01 Express van tune and what was done to my engine, he said it would be no problem. Well...
