The Digital Multi-Retard provides four different stages of retard along with an adjustable start retard feature - all of this with no modules!

The MSD Multi-Retard uses a high speed RISC microcontroller to direct the timing functions. This controller can make ex­tremely quick compensations to the timing while maintaining accuracy to within 1°. There is also an innovative Magnetic Pick-Up Compensation cir­cuit built-in to allow for rock-steady timing with a variety of different mag pick-ups.

There are four separate retard stages that can be activated independently or together for a to­tal sum of retards. Each stage is adjustable from 0° - 9° and a maximum of 20° of retard can be pulled out. On top of these great features, there is also an optional start retard circuit that can be programmed to retard the timing 5°, 10°, 15° or 20° during cranking. The Digital Multi-Retard can be used on 4, 6 or 8-cylinder engines and must be used with an MSD Ignition Control.

Good looks but cheap fabric
Size: Large, Color: Light Blue
The sizing is about right, but the fabric is really cheap, flimsy and rough. Disappointed and this is going back

Nice!
Size: Medium, Color: Bright Blue
My husband loves these. He’s got black, navy, bright blue, burgundy, grey…. and I’m sure I may be missing some! They hold up nicely after repeated washings in cold water in the machine and I always hang to dry. For golf they are fabulous because they are non constricting and comfortable while playing in the hot Florida sun which he does on a daily basis. They run very true to size….he takes his usual medium and they fit perfectly. Highly recommend!

I am thoroughly impressed with this Amazon Essentials white shirt. For the price, the quality is outstanding. The fabric feels soft, breathable, and has a good weight to it

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.
