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 Looks Nice and It Works
Color: 1 Tier-Black
I like it. It is too long for my sink area, but it still works. Next to my sink is a dish rack. One half of the caddy fits perfectly behind it, holding a 16oz bottle of dish soap and a 16oz bottle of multi-surface cleaner. The part of the caddy that fits on my sink ledge holds a sponge, scrubber and scouring pad, The caddy works great at keeping the ledge dry. It is a very nice, well-designed item. I recommend this caddy it's keeps everything organized and dry.

Good for organization, looks neat!
Color: 2 Tier-Black
I've had this for almost a year now and expect to have it for a few more; seems very durable. The drain board thingy requires consistent cleaning every few days, but its done in less than two minutes. I usually wash the entire thing every two weeks to keep it shiny as well. I am seeing a little bit of rust, but it's not too much and it's not noticeable if you don't look for it. It's great for organization and was easy to assemble. A very sturdy and well-sized product.

Serves purpose and holds what it was intended to
Color: 2 Tier-Black, Color: 2 Tier-Black
I like it. Keeps things organized and handy in small kitchen. The attachable bin holding my brushes I put on outside of unit not inside as company pics show it. That bin only has one clip to hold it in place. This makes it a little wobbly if you want to place it on the outside like I did. I used 2 trash bag twisties to help tighten it into place. Doing this made it no longer lose and the inside area space larger to hold both of my soaps. Fits everything I need it to. I appreciated the little lever on bottom that moves for water drainage. My sink design doesn’t work for the other drainage design I found these to have online.

My new kitchen favorite!!! Looks just like picture!
Color: 2 Tier-Black
Love this, looks just like picture. Fits perfect by my sink and the drain spout positions right into sink. Holds quite a few things. A kitchen must have! Well made, stays put, easy to rinse when needed and my room mate loved it too!

Great sink organizer
Color: 1 Tier-Black, Color: 1 Tier-Black
I've been searching seems like forever for something to make my kitchen sink look more organized and this caddy solves my problem!! I found a different use for the basket that holds a scrub brush since I don't use one of those. Nice design that fits my kitchen objects and no worries about removing a tray to empty water out. I used the adhesive holder to attach it to the wall behind the sink but one corner is peeling off, causing the basket to hand on that side. :( It would have been nice to have a replacement for that, but overall I'm pretty impressed with this thing!!
