Better for what application?


7 al 3 has all the bells and whistles..If it is a race car(drag racing) and you elect to use the 6al, and you want to use an electric shifter, a two step for the leave etc...then you will have to buy the 6AL Box,+ two step+ rpm switch+ whatever else you decide you need...the cost of all that mumbo jumbo will add up fast. With the 7AL-3 you already have all that crap built into the box...not to mention built in start retard ....much easier and probably cheaper.Definitely more simple wire up..It's a Pretty cool box .A friend of mine had some trouble with his but you will get that with any product I suppose....If it is a street car only with moderate compression the 6AL is a good box.

7AL3 is 10x the box the 6al is. 7al3 has everything built in it, Shift, Retards, High Side, Launch, Burnout, everything you need is there without purchasing any other boxes.

6al BOX= $ 226
3 STEP RETARD= $226.00
rpm SWITCH FOR SHIFTER = $100
3 STEP REV LIMITER= $80

TOTAL $632

7AL-3 = $ 645


And with the 7AL-3 you get Four built-in timing retard modules plus the start retard...vs the 3 retard modules in the above example

Plus the 7AL-3 has more spark energy.

I hope they got them working better now than they used to. I got one when they first came out. It was warrantied twice. Finally, I was just refunded my money...

What is the benefit of the digital 6 or 7? Do you program the timing curve or what?
