Rev after throttle input

[BraskaBurban]

I am new to HP Tuners. I recently did a cam swap and DOD delete on a 5.3 gen IV LS. For the initial startup these are the changes I made:

ENGINE- IDLE-RPM-BASE SETPOINT
850

ENGINE-FUEL-LEAN/FUEL SAVING
DOD DISABLE

ENGINE-IDLE-AIRFLOW-AIRFLOW FINAL MINIMUM
+20%

ENGINE DIAG- DTCS-
DISABLE P3400-P3449

ENGINE-IDLE-RPM-STARTUP-P/N
SET MIN TO 850

ENGINE-IDLE-RPM-STARTUP- IN GEAR
ALL TO 850

The truck starts and will idle but if I touch the throttle and let off the truck will command more than 20% throttle and hold 2500 RPM until I shut it off.

I have made no other changes other than those above.

I do not see your tune file or a log file or the specs on what cam you used.

[BraskaBurban]

I attached the tune file here my cam is 272/291, 218 int./229 exh @ 050, lift is 0.541 int./0.530 exh. and LSA is 111. STARTUP STEP 1.hpt

Throttle Learn

Without Scan Tool - Learn Procedure

Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
Start and idle the engine in PARK for 3 minutes.
With a scan tool, monitor desired and actual RPM.
The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
Ignition OFF for 60 seconds.
Start and idle the engine in PARK for 3 minutes.
After the 3 minute run time the engine should be idling normal.

Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.
⇒ If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
After the drive cycle, the engine should be idling normally.
⇒ If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.
Once the engine speed has returned to normal, clear DTCs and return to the diagnostic that referred you here.

there are alot of things that go along to get it dialed in.

i though can help getting it all sorted out with our remote tuning services [email protected] or DM me so we can talk about it

Another one with this bullshit. FFS.

Post a data log after the throttle relearn if you are still having issues

[MeshaalMMT]

just offering a service. sorry if that offended you

[blindsquirrel]

Then help HERE. Stop trying to lure people away to a private spot like you're either starting a cult or running a timeshare getaway.

[danmw2003]

Just guessing here, but adding 20% to BRAF seems excessive. If that's what you did, I'd probably lower that some. Might be why the rpm is hanging. Just a guess though.

No need to be sorry. He thinks it's his forum.

I agree with blind, advertising post from people that don’t help are annoying. I just checked out his post history and he hasn’t really added anything to the threads he has posted in.
