Thanks. I was just worried that with a different axis the data wasn’t exactly as “PNP” as I thought it should be.

No one?? Has anyone else noticed that the x-axis on ID's Excel spreadsheet has different incremental numbers than the relevant table(s) in their VCM Editor table(s)? Or that sometimes when you paste,...

Hi,
Firstly, I am not a tuner, but I have managed to do the basics on my Magnuson blown LS3 Vette, with a lot of help from HPT Forum moderator schpenxel. But, I've just recently done a flex fuel...

There’s a bunch of injector data that need to be changed, like short pulse adder vs effective pulse width, offset vs. injector pulse width vs MAP and voltage offset. But you need to have the right...

I’m not sure if this will work, but if the A/C pressure sensor connector is still there, I suggest that you would plug that onto a pressure sensor (even if you don’t have the A/C installed/connected...

As far as I know, the Gen IV GM phasers are “parked” at 8* advanced (I think there are some other designs at 6* adv., iirc), which means that is physically as much advance as you can get, because...

Apologies for just posting this now. Attached is the standard/canned Magnuson Heartbeat tune, according to the guy that sent it to me:

The Heartbeat C6 blower comes with LS9 injectors. What size pulley is on it? I should have some tunes for the standard 96mm pulley and for a 90mm pulley with the stock LS3 cam. I'll look and post...

Noted with thanks. Good to know. I'm not going to trouble it for a while anyhow.

Thanks. Will do that and test it.

Thanks, I will try that. You’re suggesting multiplying the whole MAF table by 1.2, correct?
I will also add what I can to my list of PIDs as well. Thanks again.

No offense taken. I looked at the PIDs you have and I have most of those listed as channels, although not in the graph section of the scanner. I’m not using equivalence ratio but I do have commanded...

Attached is a very short scan of the car at idle yesterday. It actually starts easily and idles pretty decent, but once I touch the throttle the rpms start to oscillate up and down. It also has a...

FWIW: Here's what my truck's tune looks like as of today. I have the phaser starting to move from park at 1200 RPM, reaching the "straight up" or 0* position at around 4500 RPM and reaching the fully...

I think so, I drove it around yesterday for a long time and sat with it idling in the driveway on the brake for about 15 minutes straight and the surge was gone. I had done this phaser mod before,...

I‘Ve been running a Mast VVT cam in my ‘08 Sierra Denali for over 6 years now. When I did it I was cursing myself for months because nobody, including Mast themselves, could (or would) help me with...

Thanks. That’s what I thought. It’s now in a 4.5” dia. tube compared to the stock Magnuson aircleaner housing, which is like a 2”X4” oval shape where the MAF is located.

Thanks again for your help. I struggle to to keep up with you guys, but I learn something new on here every day.

Yep, that’s what I have always understood - only populate your layout with as many PIDs as you need, because adding more only slows down the polling rate (if that’s the right term?).
But what I was...

Okay. Thanks, I'll create another layout with those PIDS and see how that works. BTW: From that screenshot that you posted, I see that your layout is completely different from mine and some of the...

This what has always baffled me. It only happens at WOT, at the top of the RPM band, and almost always happens only in 3rd gear? I was wondering if it was hitting the limiter and then going into REP...

I’ll give that scaler a try, once I get it on the road, thanks. When you say “back off the throttle opening rates”, what do you mean? I thought we couldn’t mess with those settings?

Thanks, I’ll take a closer look at the log shortly. I hadn’t even noticed that. Weird that it’s moving timing around like that. I haven’t had a problem with mixing non-oxygenated non-E race gas with...

No, I haven?t tried the NW yet. The log I posted was from a few weeks back.
I had already done the slave segment update which added the P1516 DTC adjustment, and then, on the advice of a very...

What part of the log are you looking at? It typically pulls 8 degrees of timing on each shift via TM. I have never seen KR on this car, or heard knock. I typically run this thing on a 50/50 mixture...
