Boost timing

[tooslow]

I am putting together a Novi 1500 , 440, 6 to 8 psi boost
Quesstion
I have an MSD 6AL ignition and I thought MSD offered a simple boost ref add on timing retard but I cannot find it.
For my initial Drive/ tuning can I retard the timing to say 22 degrees until I update the MSD to a unit with a boost ref retard?

BTM Boost TIming Master is all I can remember.

Yup a btm would work good for you. They work up to 15 psi

REally?...to give the Best Advice....I say sell the 6-AL....and get a Digital-6.

Problem solved....completely controllable timing....and you can use your stock electronic distributor.

The Digital 6 is a nice piece but it does not come standard with anything to progressively retard timing on boost. You would need to stack an add on to make it happen.

Personally, I'd recommend the Accel 300+ & 375+ Combo.

Way more features than the 6AL and Digital 6 offer, programmable with a handheld remote too (that also functions as gauges). No Dial/Switch crap to mess with, you can put the ignition components out of the way and use the remote to handle everything instead.

I have the 300+/375+ combo on my vehicles and love it.

My bad...I was remembering the wrong units specs.....confusing different units...its the 6530...6AL-2 I was thinking about....although your right the Digital 6+ is a nice piece and one would have to accessorize it for best operation....

But what I liked about the 6AL-2 was:

Laptop Programmable

Fully Tuneable Boost Timing Curve down to .01* every 100rpm

3 rev limits

That's the one!

Yep. That's what I run. For the guy with a old School 6al that only wants 10 psi the btm is fine.

X2 on the msd 6AL 2 programmable, you'll need a map sensor also and make sure to spend some money on a good wideband for your afr readings

Thanks, I am on a budget and the Boost Timing Master was the answer. $250 and I retain my 6AL.
