Stop the competition in your 2017-2019 GM 6.6L Duramax L5P with the Banks Power 66682 Derringer Tuner (Gen2). This value priced, feature packed tuner gives you torque and power gains across the full RPM range. Starting off at idle, and marching to the shift point in each gear. Designed to use multiple data inputs such as throttle position, RPM, vehicle speed, AFR, knock, and coolant temp just like your engine's ECU. It's microprocessor based electronics are able to actively and safely optimize calibrations in real time, unlike other products on the market.The Derringer has three switched settings: Stock, Plus and Sport. Sport produces Best in Class performance knocks you back in your seat. The Plus setting is for work use and has great mid-range feel. When running Plus with a loaded work truck and/or pulling a trailer, your on ramp merging speeds and passing times are greatly improved. The Derringer is the only tuner that actually utilizes your truck’s ECU to make intelligent calculations!
The electronics are molded into a waterproof connector, which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as the iDash 1.8 Super Gauge/Control Center. The Derringer connects in line with the Throttle Inlet Pressure (TIP) and Manifold Absolute Pressure (MAP) sensors. But, unlike others it also connects to the vehicle's OBDII diagnostic bus connector. A CAN (controller area network) transceiver chip communicates with OBD or B-Bus allowing our microprocessors to talk with the vehicle. And, Derringer's special coolant temp watchdog prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer, you just choose your setting.
AutoRate
Unlike the fixed tuning used by others, the Derringer calibration is continuously adjusting to provide you the peak possible performance under every driving condition. By utilizing the power of the OBD-II data, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level
Exhaust Gas Temperature (EGT) – The Derringer senses your engine’s EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
Altitude compensation – The Derringer senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.
Diesel Particulate Filter (DPF) Regen – The Derringer tuner constantly monitors your DPF regen status and will optimize its calibration to ensure the DPF regen process completes successfully.
Accelerator Pedal Monitoring – The Derringer senses accelerator pedal position to roll in additional power progressively, optimizing partthrottle fuel economy and giving max power when you ask for it.
Coolant Temperature Monitoring – The Derringer senses coolant temp to control added power. During warmup, no power is added below 120° F, then power is ramped in and fully available above 150° If the coolant overheats for any reason, the Derringer starts removing its power at 230° F and additional power is totally removed if you exceed 240° F.
Full Power Timer – If set on Sport level, the Derringer allows for 30 seconds of wide open throttle before transitioning to the recommended power level for sustained tow/haul. (Our research has shown that the stock L5P when at full power will hit 1450° EGT and after a minute or so will pull out fuel to cool things down. So, we do the same thing.)
TransCommand Active Transmission Safety System
In addition to AutoRate Adaptive Tuning, the Derringer utilizes key engine and transmission parameters to enhance shift performance and improve the longevity of your transmission. Because the competitors lack the essential OBD-II data, they always add power at wide open throttle—no matter what! This can cause excessive transmission slip, torque converter clutch slip and even 170 HP engine derates in order for the transmission to complete the shift. This harms the overall performance and degrades your transmission. The Derringer is meticulously calibrated and extensively tested to properly modulate power during shifting, optimizing performance and safety
Intelligent Shift Tuning – The transmission shift request signal is monitored to optimize the power level prior to the shift protecting the transmission, increasing shift speed and avoiding ECU power derates. Boost and Fuel by Gear – Gear based calibration allows for optimum traction and performance Torque Converter Clutch Slip Monitoring – The Derringer adjusts to modulate TCC slip to safe levels. Transmission Slip Monitoring – The Derringer adjusts calibration to modulate transmission slip to safe levels
ActiveSafety
The Derringer is the only tuner on the market to include ‘Active Safety’, an active failsafe system that utilizes bypass relays to smoothly transition your vehicle to stock power levels in the event of any trouble signs in the Derringer. The system constantly monitors various parameters at over 50 times a second to ensure that everything is operating as it should. If any competitive tuners loose power or fail in any way, they will instantly trigger a “limp home” mode where all power is lost and the vehicle dangerously slows to a crawl. If the same fault condition occurs to the Derringer it will gracefully remove its additional power and return to stock power levels without a hitch
Internal self-diagnostics checks health of the system 50 times per second Monitors MAP and FRP signals for out of range condition (disconnected or short circuit) Watchdog timer constantly monitors CPU activity Active safety engages if 12-volt power is lost to the Derringer tuner
iDash 1.8 Additional Features
The iDash 1.8 provides addition features to your Derringer Tuner. The 6 power levels can be changed on-the-fly with the iDash, and the optimized Derringer Layout allows you to view vital data from multiple engine or transmission paramters. In addition, the system can be expanded with other Banks Bus products (not included). 6 Power Levels with on-the-fly adjustability Optimized Degginer layout to view vital data Regen status displayed over power level when regen is active Power added bar graph shows Derringer power being added On-screen Derringer status indicator

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it!
I live in Florida and flat tires are just part of living here!
Saved my life twice already and is absolutely self explaining!
Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well.
When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean.
I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me.
Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,.
Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.
