MSD Ultra 6AL Plus Ignition Boxes

The new Ultra 6AL Plus ignition boxes deliver full MSD power in a compact, lighter package! The Ultra 6AL Series continues to use a high-speed controller that can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm limits, while maintaining precise timing and accurate rev limiting. The circuits and controller of the MSD have been thoroughly filtered to create protection against Electro Magnetic Interference (EMI). Ultra 6AL Series features a capacitive discharge ignition design. (The majority of stock ignition systems are inductive ignitions, in which the coil must store and step up the voltage to maximum strength in between each firing. At higher RPM, since there's less time to charge the coil to full capacity, the voltage falls short of reaching maximum energywhich results in a loss of power or top end miss.)

MSD Ultra 6AL Plus ignition box details:

* High conversion efficiency ensures minimal heat generation and maximum spark energy output with less current draw from the battery
* High RPM operation and maximum output using the Blaster HVC, PN 8252 or HVC II, PN 8253
* Powerful capacitive discharge of multiple sparks improves performance
* Consistently high spark energy of 135mJ to 150mJ for every firing, from idle to redline RPM
* Increase spark series duration lasts for 18 of crankshaft rotation
* Easily installs on 4, 6, 8-cylinder engines with distributors
* Operates on most 7 to 28 volt electrical systems
* Connects to points, magnetic pickups, and hall/crank input distributors
* Bluetooth connectivity to mobile app interface for settings and monitors
* MSD CAN communication for easy connectivity to MSDView using a CAN MSD Hub and Power Grid USB or CAN-USB Bridge 89982 product
* Straight USB port to easily connect to MSDView using a laptop
* Fully protected against an open coil, shorted coil and open load
* Compact design full MSD power
* Quickens throttle response and improves starting
* Tach Output
* Launch, Burnout, and Step Retard activation inputs available. This ignition box has a built-in tri step RPM rev limit controlled by the mobile app
* Mobile app available settings: Step retard value, Launch RPM value, Burnout RPM value, Max (Race) RPM Value
* Programmable Step Retard: On Ramp time, Off Delay, Off Ramp Time, Engine RPM for activation
* Programmable Start Retard through rotary switches: 0, 10, 20 degrees
* Programmable cylinder selection through rotary switches: 4, 6, and 8 cylinders
* Alerts and monitors available
* High level of security connection from phone to Ignition box (encryption), including sequence in push button implementation
* Maximum programmable retard of 35 degrees
* Programmable timing curves in 2D plots or 3D tables (RPM vs Timing vs MAP Pressure); you can plot the 3-D graph and edit a table 20x20 either from mobile app (phone) or from MSDView (laptop)
* Programmable Launch Timing (seconds vs degrees after launch wire activation)
* MAP sensor interface up to 400 kPA (58 psi / 4 Bars)
* Capable of programming cylinder selection and start retard without a computer or app for old school racers (like 6425 or 6428 box)

It serves it's purpose!!
Size: 1 Panel, Color: Black
Product really works well & serves it's purpose! Great height & width. It's flimsy, but it will stand still when put in place.

Zero stars
Size: 1 Panel, Color: Black
The bars are impossible to screw in all the way so it’s not sturdy at all, trash and waste of time

Great product, sturdy and well made. Easy assembly.
Size: 3 Panel, Color: Beige
These are awesome! They were easy to assemble. They are lightweight and easy to move. I was able to easily put all 6 pieces -(I ordered two sets)-into the back of my SUV at once, by myself (and I'm a short, older lady). Quality material. Very sturdy and steady. The first set I opened was a used one and did not include instructions, but it was still very easy to assemble and figure out. I recommend using a battery powered screwdriver. With that, the assembly of all 6 panels took less than 45 minutes.

Defective product
Size: 1 Panel, Color: Black
All screws cannot fit with each connectors. The Allen key provided is useless because it doesn’t fit into screws.

Love it, happy with the price
Size: 1 Panel, Color: Black
I have been using this product for a month now. I'm absolutely thrilled with my new Room Divider. It's has made a significant difference in my home. The divider is not only stylish and well-crafted but also incredibly functional. It has effectively separated my open space into cozy, distinct areas, enhancing privacy. Assembly was a breeze, and it's built to last. This room divider has truly transformed my living space, and I couldn't be happier.
