We were on I 70 about 40 miles west of Baltimore MD. It was 102 degrees on a Friday at 4:30PM and we had our 40' 5TH wheel in tow. There was an accident and traffic quickly came to a stop. The MEDIVAC chopper flew in so we knew we were stuck for a while.

After about 10 minutes of idling the engine stalled. I cycled the key off and tried to restart it. The engine ran like the key was being rapidly cycled on and off. The engine stalled and would not start.

I checked for codes in the Banks tuner and found none. I checked for OBDII codes and found 10 . Lost communication with ECU and low voltage to just about every sensor in the system.


The MEDIVAC chopper was leaving and I was desperate to get moving. I tried to clear the codes but my Banks tuner would not respond. I popped the hood jumped out of the truck and disconnected the Banks 6 Gun from the ECU and reconnected the stock connectors. The engine started and ran fine. We drove over 150 miles to our campsite with no problems.

The next morning I reconnected the Banks 6 Gun. The truck started and seemed to run OK. I took it out for a 30 mile drive. It ran fine so I let it idle for a while. After about 10 minutes it stalled and would not restart. Once I disconnected the Banks 6 Gun it started and ran fine.

I emailed Banks twice in the last two weeks and they have not responded. If I ever get this resolved by either Banks or myself I'll let you know.

Give it a smack with a 3 lb. sledge and recycle it. Next get a PPE no more issues. Use the IQ for monitoring stuff if you have it. Can't save those 6 guns from underhood heat the record stands. It's to dangerous to run that stuff maybe put it under the dash if you have to run that brand it will work better without the heat from engine on it. Good Luck..

Sounds like there's a connection problem in your wire harness. PM me your phone number and I'll get one of our tech guys to give you a call and get the harness tested for you:)

So when the module under the hood gets heatsoaked it causes a bad connection in the wire harness,good luck on that one!

Same problem I had.. Banks Claimed some bs story... when I took it in. It seems this problem has happened multiple times.

He's had this on his truck since 2007:rolleyes:

You think you've seen it twice, you haven't. Both of your tuners were just fine, the problem was in your harness. If the tuner is overheated it will shut itself off, throw a code on the LED's and the engine will run at the stock power output. It won't ever shut the truck off.

You'll here from James in our tech support shortly:D

here we go again :cool: :coolnana::boxing::duh::smashfrea

If the problem was in my "harness" why couldn't any of your tech guys figure that out?

Their only ideas were some magnetic pulse or being under dozens of high voltage power lines.

And both trucks had the six guns installed at bank's shop.

According to my sales men both tuners were built 9 months apart from each other. And were installed a few weeks apart...

Does that mean your installers did something wrong?

You'll here from James in our tech support shortly:D
Jeff, James called me yesterday but I didn't have time to talk. I'll be calling him today. Thanks

As you were told when we took them off for you, the tuners tested fine, they did not trip on an overheat, there was no heat soak problem, but you didn't want to wait to have the harness checked. You just came in, wanted us to remove it and then take off. Ever since then you've been claiming there was a heat problem when you really have no idea:rolleyes:

Jeff, James called me yesterday but I didn't have time to talk. I'll be calling him today. Thanks

I saw that, if you can't reach him direct just give me a call here:D

Mr. Barker, I have had this exact same issue on 2 different occasions this year. My 6gun PDA has been in since June 07 as well.

Only seems to happen when IAT is extremely high. As in parked in Idle on a very hot day with the AC running. Same symptons, same issues. Truck dies, truck will not start. checked for codes: First time was crankcase sensor & injector harness issues. It ended up costing me over $ 120 CAD for new pigtail on # 7 injector until I realized it was the Banks system...and nothing to do with the stock set up at all.

2nd time, same environment: super hot humid day over 100F, AC running parked in idle. Truck dies...this time I did what most of us learn..pull the banks off and get moving.!

There is an issue here to do with heat. What the heat is affecting, I do not know...but affecting the system, it most definitely does. I suspect it is the module...or the connectors...or something that I have done.


Now..to be fair and to help in understanding what I have done, I had applied to both of my connectors, a bit of dielectric grease...(I live and drive in an environment that in winter time is somewhat corrosive in the amount of road salt used and as such it seemed to be a prudent thing to do).

But it may be that this grease is getting so warm as to flow somewhat and llow cross connection on some ofo the pins to cause a short or miscommunication...?? I have since cleaned out that product from both sets of connectors as well as cleaned the OEM receptacles and have not had the issue since ... but then it hasn't been very warm up here with temps in 70's only...so will have to wait till next summer to see if the dielctric grease was the culprit

I had the same problem. Tow my camper on a hot day, stop and let the truck idle for a few minutes, truck starts running on 2 or 3 cylinders and sets about 10 codes. 'Take the 6 Gun off, reset the codes and the truck runs fine. Banks wouldn't talk to me directly because I bought from one of their authorized dealers instead of factory direct. The dealer had me try a couple of things but I had no way of knowing if they worked till it got really hot under the hood.

I finally got authorization to send it back to Banks but again I had no way of knowing if it was fixed until it got hot which by the way it wasn't. By this time, the warranty had run out and we were going on an extended trip so I just threw the tuner in a box with some other junk in my garage where it's been for about 2 years.

It's unlikley the grease is the problem as dielctric is non-conductive. Any time the connection is broken it will cause numerous codes and drivability problems. The modual overheating WON'T cuase this. An overheated unit will simply shut off and the truck will run stock. It would basicly be the same thing if you pull the fuse out of the harness. This is one of the saftey features we put in the unit itself. If the truck is dropping cylinders and setting a bunch of codes the problem is in the harness. One or more of the connection pins is either loose or not seated. The best way to check the connectors is to un-plug them and VERY GENTLY pull back on the pins with some needle nose plyers. A loose pin will "click" back into position. If the connectors are good then you need to call our tech support department, or the dealer you bought it from, to get the harness tested or replaced.

Is it the same unit you sold here?:

Talked with Banks tech support yesterday. They want me to send them my tuner for testing. I'll have to wait and see if they find anything.

I'll let you know when we get it back in:D

Yeah Mr Barker, that's it. At the time I posted the for sale, I hadn't seen any posts of similar problems so I figured maybe it's my truck. After all your tech department had just checked it out. Nobody bought it, you interested?

So you didn't install it after you got it back?

Yes sir I did. Ran fine till I towed my camper on on a hot, 95 degree day. I stopped and let the truck idle for a few minutes while checking into the campground. When I pulled away, the truck started skipping and CEL came on. I took the tuner off and reset the codes and the truck has ran fine since.

Mr Barker, I didn't post this to bash you or Banks. They're great tunes, at least the 20 and 40 hp tunes are great. (I never ran it above that.) The truck with the tuner installed crapped out about 6 times, all on hot days and all while towing when under hood temps were likely very high. I posted to support the other guys who have had similar problems. Isolated or not, there is a problem somewhere. If it happens with the tuner but has never happened without the 6-Gun installed.....well

I guess I made a mistake by shopping around for the best price because it basically blocked me from any direct contact with Banks technical support. I'm long out of warranty and do not have an agenda. Have a good life......

Once again, you sent in the tuner only, not the harness. The problem is in your harness. I just find it strange that I can't seem to find any questions from you (pm or otherwise) reguarding the shut down problem until this year. I also find it strange that you tried to sell the tuner with a problem like that.

I sent them all that I have, which is the tuner and associated cables including a six position knob.

As I mentioned previously, I called Banks tech support and got the recording saying that if I bought from an authorized dealer then I should contact that dealer. I don't know you and have not bought anything from you so as far as I know, you would have told me the same thing. I did talk to the selling dealer three or four times. He had me try a some things which worked until I guess it was hot enough under the hood. He got authorization for the return, I sent the unit directly to Banks along with a note.

The idea to sell it may have not been thought out very well. I figured that if your techs checked it and sent it back, then it must be my truck. At the time, I wasn't aware of anyone else having the problem. As I said in a previous post on a different thread, I'm glad I didn't sell it. If I had and the buyer had a problem, I would have refunded his money. If I'm gonna screw somebody and make an enemy, there needs to be more than 200 bux involved......
