Product Description

Product Description

MSD 6520 Digital 6-Plus Ignition Control Box

From the Manufacturer

The all new MSD Digital-6 Plus Ignition Control embraces advanced digital technology to take performance ignitions into the future. No other digital ignition can match the power and efficiency of the all new MSD Digital-6 Plus.

MSD combines race winning experience with cutting edge technology to create the most powerful Digital Ignition available. The Digital-6 Plus is Digital Done Right.

The heart of the Digital-6 Plus Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. What this means is the controller analyzes up to 15,000,000 critical instructions per second. This is over three times the speed of comparable ignitions and produces the most accurate trigger signals, timing and rev limits possible.

MSD engineers have spent an endless amount of time testing the components of the Digital-6 Plus to ensure the most efficient and reliable operation. The 6 Plus produces more power with less current draw (20% less) by incorporating an IGBT coil driver that can be controlled for improved coil saturation. Also, power MOSFET technology and high frequency magnetic converters require less input current while producing more energy and voltage.

Every spark of the Digital-6 Plus ignition is packed with 135 millijoules of spark energy and up to 535 volts. When used with the MSD Blaster HVC Coil, PN 8252, a spark with over 300 milliamps burns across the plug gap for 400 microseconds. Below 3,300 rpm the Digital-6 Plus produces a series of sparks that glows in the cylinder for up to 20° of crankshaft rotation. This incredible heat ensures combustion to produce great power, quick throttle response, smooth idle and quick starts.

To prevent any chance of Electro Magnetic Interference (EMI) a filter circuit is made up of state-of-the-art magnetic suppressor components. This, combined with the more than competent microcontroller, checks and rechecks inputs many times to determine "clean" signals before making any compensations. The magnetic input also features a unique micro-controlled feedback circuit for total EMI-free operation.

FEATURES

  • Adjustable rotary switches in 100 rpm increments.
  • Single stage retard for nitrous and top end performance.
  • LED display warns of trigger signal problems or faulty charging system.
  • Polyurethane Potted for vibration/ water protection
  • C.A.R.B Approved

    SPECIFICATIONS

    • Operating Voltage: 12-18 volts, neg. ground (Full voltage output down 7 volts supply)
    • Current Draw: 0.7 amps per 1,000 rpm (7.2 amps) with 14V bat. @ 10,000 rpm
    • RPM Range: 12,500 rpm with 14.4 volt supply
    • Spark Duration: 20° crankshaft rotation thru 3,300 rpm
    • Spark Energy: 135 millijoules per spark
    • Weight and Size: 3.7 lbs, 8.5"L x 4.5"W x 2.2"H
    • Voltage Output Max: Primary: 535 Volts delivered to coil, Secondary: 45,000 Volts (MSD HVC Coil)

This MSD control box did not work at all. So I called MSD to find out is there something I can do or needed to do and they said that the unit is defected just sent it back to Amazon. I could pay to ship it to MSD to have them check the motherboard that would cost me anywhere between $20 to $120 to check out the unit. They recommend that I sent it back to Amazon. Note I had a msd 6al on my car and it ran great I wanted to update my 66 Ford Fairlane,

DO NOT BUY FROM AMAZON
As stated above I ordered a MSD control box and it did not work.
Amazon has charged me $100 for the Box not working they knew it was junk when they sent it as stated from me and other buyers and still charged me do not waste your time with anything from Amazon.

The 1st one had a bad tach output. The 2nd seems to working great. I'm a little worried about longevity. Nice unit though with great features.
