I would also go to Engine Diagnostics--Airflow--P0086 and make that 8000rpm.
I zero out the maf table except the first two cells. Here is a screen shot. I have tried as high as 15 in those two...

Big thumbs up. Didn't know that.
I bought a Whipple that was for a 2019 Silverado from a buyer that was about to send it back. It was for a direct injected truck.
I called Whipple to see if I...

When you say the donor vehicle is a 2019----isn't that a DI engine you are putting into your '03? If so, your '59 is not going to fire the injectors.
I put a 2015 L83 in a 2000 Camaro and used a...

What about 2highpsi ?

Assuming the key is ON---
Mine does this sometimes. When the message comes on, leave the key on, unplug the HPTuners cord from the laptop, it should make a noise, replug it, again it should make a...

I don't know about the calculated torque stuff, but here is what I did to reduce some of the timing dip during shifts. ---Not saying it is correct, but it makes the shifts a little crisper? I have...

How about this?

Got it

Is there a way to do the relearn when there is multiple DTC's---rear O2's, heaters, no emergency brake connection, and a couple more. HPT has the O2 dtc's blocked out so cannot turn off that stuff. ...

I'm using their IAT sensor, but not MAP. You can get the info quick if you call them.

What is non projected for Gen5 heads other than the Brisk that you recommended? Thanks

I reduced timing to 10 degrees at wot, made two runs and only got .4 degrees knock retard on one of them. Now to get my E85 sensor wired up and I will be OK. I reduced the last row of timing from...

Did you call Motion to get the correct math?

No, nobody around here has Brisk plugs---podunk Fl. , but I did the 45's on the exhaust and went down to the local parts store and got some "guaranteed" octane booster. It kept the knock down to...

Time for some better fuel. Took out about 3-4 degrees of timing, and left it rich. Still knocks.
Be back later

I added 10% fuel from 127kpa up to 255---from 4000rpm to 6800rpm.
10 degrees knock retard. Looks like I will be shifting at 4000rpm. I guess some better fuel is required? Is any of that octane...

I can do that. Thanks
Here is a new log with the knock sensor sensitivity at 129---still knocks.

I changed the knock sensor number to 129.. Bad thing is, I don't know if the wideband is correct, so I can't adjust anything til I get a new one. Crap!! I will check to see if the knock goes away...

Cam is CamMotion 230/248, LSA 115.5, Timing 4.5 advance, Intake CL 111.0, Exhaust CL 120.0, .631/.629 lift @1.8, Overlap 8.6
IAT's will get up to 127 with a longer pull.
First post shows closer...

I thought I replied?? Don't know where it went
The Gen 5 heads use a longer plug. Would the shorter BR7's work?

That's what I used before---your recommendation. These Gen 5 heads take a lot longer plug. I don't know how that short plug would work out??

I had a LS3 that was 10.9 compression with a Magnuson at about 12psi and never had a knock problem. The spark table for this engine is the same one that I used for that setup.

Iat is in the blower lower housing. Post blower.
Thanks

Since the two widebands do not agree, I am concerned that this is not going to be right. The only time the widebands are used is when I am tuning my car. They don't stay in the exhaust every day.
