I have the MSD DIS-4 part # 6215 that is listed on Jegs for $639.99 and I have the Programmable-Multi Channel Boost Retard Controller part # 6562 that is listed for $654.84 on Jazzproparts.com. This is what they say about the Boost Retard System:
MSD 6562 Multi-Channel Boost Retard Ignition Systems
For DIS engines receiving turbo and supercharger upgrades, the MSD Multi-Channel Boost Retard Controls are the answer for total timing control! These systems are designed for distributorless ignition systems that are already equipped with an MSD DIS-4 Ignition system. These Controls let you program a variety of performance and consistency improvements along with the ability to control the ignition timing in relation to the boost pressure. When air is being forced into the engine damaging detonation becomes a concern. These Controllers let you easily retard the timing as pressure increases to prevent detonation from occurring while performance improves. Other features that you can program include rpm shift light points, timing retard steps for each shift or in times of nitrous shots and a launch retard. Being able to pull timing out during the launch will help compensate for altering track conditions. If you have more power than tire, removing some timing will help soften the initial hit of power and prevent tire spin. With the MSD you can control how much retard is activated and the amount of time it takes (up to 2.5 seconds) until the timing is back to the run curve! By adding a sync pickup you can also control the timing of each cylinder. Being able to control the timing of each cylinder will save you from having to compromise the ignition timing in the rest of the cylinders. MSD offers a Universal Cam Sync Kit, PN 2346, that you install to sync with the number one cylinder so the ignition knows which cylinder is firing (sold separately). Programming all of these features is easy with the MSD Pro-Data+ software from your laptop. This is a Windows based program that features a plotted rpm/timing chart (and boost) for the entire run. There is also a tachometer, a timing retard and a boost pressure gauge plus a complete ladder of all of the adjustments.
I'm asking $1000 for all, it has all the software,wire harrness, never used it. My engine management system wont need all this, I could add it if I wanted to but I can program it all the way I want, the boost retard controller is nice though. Like I said, I'm asking $1000, something close might get it. Its all brand new still in boxes..
