Banks issues

[Azdc]

Hey guys.. I have a 2024 l5p and recently installed the banks derringer, intake, turbo inlet, map sensor spacers, pedal monster and idash setup.

Long story short, I’ve had nothing but issues.. I’ve been working with the banks team to troubleshoot this surging symptom, where the truck feels really choppy under low amounts of acceleration. It’s most notable at around 45-55 mph when you roll into the throttle about 10-15% of the way.. it just starts stuttering/surging.

Most recently I got a range of codes which dropped my truck into limp mode. Most of the codes appeared related to MAF sensor issues. I then dropped the banks bypass plug into the derringer, and surprisingly found the truck is still surging. Thinking this is now actually related to the intake and their MAF adapter rather than the derringer.

Has anyone else experienced this? Starting to go a little crazy in how many weeks I’ve been dealing with my truck feeling so terrible.

That's a lot of coin to have that issue.

I would remove the pedal commander and eliminate that aspect. Can't believe it would be mapped wrong, but I've seen some weird sh!t. Especially electrons controlling something compared to mechanical controls.

 

[Azdc]

Yeah it’s definitely frustrating. Being able to do everything at once has definitely muddied the waters in terms of convicting where the issue is, but you’re right I should at the very least remove the pedalmonster to rule that out as well, will be giving that a shot today.

Ditch the spacers I had nothing but problems with mine. I have a very similar setup to you shy of the turbo inlet. Zero issues since removed.

I agree on the spacers, weren't banks but s&b. They just move the soot problem away from being easily cleaned.

Were you seeing other problems?

I had the lag and codes as well. The surge/lag happened immediately following the code was thrown. Difference with mine and OP's is his being a 24 has 2 sensors/spacers, mine a 22 has a single.

Helped a buddy install his banks turbo inlet, no issues for weeks. He then gets the intake. Soon as the intake went on, he described the same problems you have with stuttering etc under lower speeds like that since.

Banks has really messed this one up. This is why I refuse to install any performance parts on mine. I only run VSE's fuel filter setup, CCV and catch can. I also have the banks rear end cover and I run both MAF spacers no issues. Did you clean your sensors when you installed them? That might be part of your issue. Never clean those. Replace. Once a year.

Appreciate all the wisdom guys. I did not clean the map sensors when I installed the spacers, they were dirty but not too bad so left them as is. Luckily my truck only has about 7k miles… I did go ahead and remove the spacers today though.

So intake, turbo inlet, derringer/pedal monster both disabled and it still surges. Really think it has to do with their intake and the adapter they created for the MAF sensor.

I have a 25' with the spacers installed and no issues. One thing that I've noticed, and the master tech at Chevy told me, was that these trucks require a certain number of ignition cycles to actually clear these codes and have them reset. I installed Banks oil-trans-diff pan and it threw a code. No limp home. No reduction in power. Truck still drove great, but I had a CEL. Nothing else on the vehicle changed, but after 7-10 times of starting it and putting a few miles on it (approximately 50), the code went away and was not stored either because we used GM's diag scanner.

It might suck but, pull everything off and reinstall everything one thing at a time, then take it for a drive. I'm sure you'll find the culprit that way.

I would agree with your assessment. None of the issues you describe have been brought up until that intake came into the market.

My other concern about this intake is that GM keeps releasing over the air updates - some of which could potentially include different air to fuel ratio changes etc. I'm not an electrical guy, but whats not to say the banks software in that adapter is only good for GM version X. Are they going to provide updates? Is in it even possible to update that banks module? Or will the updates come through the idash? And how long will they take to come?

I have that same investment in Banks as AZDC along with boost tubes and all cool runner pans and diff cover. I have had issues also…since the derringer install for the most part. I installed my Banks CAI before the Derringer and didn’t have issues until the Derringer installed. I just finished a trip with tow over 1500 miles and have IDash Pro digital values that are two dashes and I have to power cycle to get the digital values back by unplugging the OBD and reset/Banks IDash restart everything to get the values to come back. My surging and “shuttering” seemed to stop after the latest Derringer update to 1.08. Have you updated the latest Derringer software? What is my main issue now is having to power cycle and restart the Banks IDash. Every time I check for DTC codes and clear any I loose the IDash values in the Derringer/Pedal Monster combo screen when I go back to normal operation. Overall it’s working better with the 1.08 update it’s just the power cycling reset for me is my annoyance now. I’ve sent Banks videos and texts and waiting to hear back from them as I type this to see what they say about the fix….Banks so far for me has been excellent with response.

I have 3k miles on my 25 AT4 and I was driving back from Ohio and the CEL came on with code P04DB. I have the Wehrli CAI and intake air horn installed. I have had the same Banks Pedal Monster installed on a Sierra 1500 and a RAM 2500 prior to it. I had no issues with the Pedal Monster on either. I had the Banks MAP sensor spacers waiting to install with the Derringer and boost tubes next week. I did not experience any drivability issues after the code but only had about 100 miles left on the trip. I pulled the MAP sensors, cleaned with MAF cleaning fluid and installed the spacers. The CEL is gone and I ran the diagnostics and it shows no codes both with ONSTAR GMC app and with my Innova 5410 scanner.

Looking for an update on this as I am getting ready to install my Banks CAI, inlet, boost tubes, all 3 pans, iDash Pro, and derringer. I don't feel like installing "problems" since my stock truck (24 AT4x diesel HD) has had zero issues in 13k miles since new.

Thanks !!
