I've been looking for a good ignition for my nitrous application that would include a timing retard, rpm window switch, and a rev limiter. So far I've come up with the mallory 685, which looks awesome and kicks the crap out of the msd digital 6 which requires the use of additional window switch boxes and such. Any other good "all in 1" ignition boxes out there?

 

My friends and I have had nothing but problems with the digital 6 ignitions. I am using the 6A with a single stage start/retard add on box that total cost me $135.

 

i have had a digital 6 in for a year with no problems and yes it does need another window switch

That's cool, but I'm not interested in extra add ons. I'm looking for exactly what the title states. Just wanted to know if anyone knows of any other ignitions out there similar to the malory 685, or one with maybe even more features like a progressive controller?

 

I have a mallory 685 on my vette and love it. It doesn't do progressive control, but it has timing retard and window switch functions.

FWIW, my car is a six speed. I was able to use multiple WOT switches inside the center console to activate 3 stages of N20. I have one switch set up so it's pressed when the car is in first gear, another in 2nd, another in third, and another in 4th. The thrid and 4th gear switches activate the same circuit though. I come out on a 75 shot, grab another 75 in 2nd for a total of 150, and then hit it with another 100 in third for a max of 250. It's great for on the street too. Whatever gear I am in, the N20 system sprays the right shot.

E-mail me if you want a wiring diagram.
