MSD 7535 digital ignition

I am selling a used MSD 7535 in "Like New" condition. This was mounted inside my car, not the engine compartment. This box is in perfect working order. It had never been out of the car untill now. Any questions can be directed to me at any time.

$550.00

Here are some details from MSD's web site:

The 7537 Programmable Digital-7 Ignition Control will deliver more tuning opportunities than you thought possible! Racers running normally aspirated, nitrous oxide or forced induction systems can all take advantage of the PN 7535.You can easily map out a timing curve for each gear (up to six), so you can match the timing exactly to the rpm and load on the engine. For nitrous applications, there are separate step retards that can even be ramped on and off over time. For blower or turbo cars, there is a separate map that lets you program a timing curve based on boost pressure. This is set in increments down to 0.25-psia for every 0.1 degrees. If you're going the boost route you will need to purchase a MAP sensor to meet your application (see below). delivers a stout 190 millijoule spark with 535 volts of primary voltage, so even with high boost pressures the fuel is going to get lit. All of this power and adjustments are managed by a very quick 40Mhz RISC microprocessor.

Map a timing curve based on boost pressure.
Plot timing curves down to 0.1 degrees every 100 rpm.
Control each cylinder's ignition timing by up to 10 degrees.
Select different rpm shift points for each gear shift.
Program a specific timing curve for each gear.
Three stages of retard for multiple nitrous systems.
