Thanks all, we share the same opinion. Shotty work from a "pro"..

Is this not the narrowband readings? I don’t think he went to closed loop after dyno which would cause issues right?

Just wanted to report a k, good tip on checking out the fuel pump! Not enough capacity in the stock regulator and fuel was boiling in the pump...

@Rob@HPTuners If you want to make it easier to tune SD for regular people, then please add simple screen where: 1) there are 3 sliders for Slope,...

You dont have to program it. If it set a DTC, turn truck on to service mode and clear it. then start engine. shut off and let everything go to sleep...

Never mind base running idle airflow lol. I?ll get it figured out eventually.

What is braf? I?m going to make the changes Yall have outlined in a couple hours and update

@Alvin, I am tuning the ECM that is in the vehicle already, that is what I am trying to say. It reads off a 2011 GMC Yukon VIN. Someone must have put...

I was looking for that photo but couldnt remember where i seen that at.

I need to turn off close loop enable by changing ECT vs IAT cells to 284.

I thought i had turned the closed loop off in the tune file. Could you check the tune file and see where I made the mistake?

I still don't understand why you are not tuning the ecm that's in the vehicle already. Unless this is a swap You can't copy things blindly...

Do you understand you are not helping things leaving it in closed loop with one sensor off line like that? It looks like you left the sensor...

VE from cammed 4.8 with LS3 manifold and adapter plates. Swapped into a lexis SC400 used in 7-24 hour races in that Lucky dog racing league. ...

Alvin, I had the wideband in the passenger side. I need to purchase an adapter to have the wideband in the exhaust in the rear.

Sorry @Alvin, I did not mean to say I "stuck in a 2011 Yukon file". I meant it as in the tune is "stuck" in a 2011 Yukon file. The ECM in this truck...

Yikes!

Tune File

If the OS is incompatible with the fans it would be easy to build a discrete - PWM converter with an arduino. Very easy.

I followed the instructions and added each file. It seems to add as a picture instead of a hpl or hpt file.

I'l bet you didn't address the IVT terms with your scaling.

I don't understand why you "stuck in a 2011 yukon file" Why did you do this? There are a ton of things I see off in this tuning. The high...

I don't see how you can leave them stock with boost, really.

in my first reply here I talk about how complicated it is. My reply was simple to match to OP's simple comment.

You can log "throttle cracker airflow" and "Throttle follower airflow" to get an idea as to what is added when. When it is coasting.. it still...

Your passenger side O2 sensor is bad which is causing the fuel trims to dump as much fuel as possible on that side. I'd get that fixed and change...

BRAF is too low from experience. Log STIT and LTIT to see how far this table is off. The VE is going to be the foundation for tuning this thing and...
