The analog stuff either works or is completely dead...at least that's been my experience w/ the 6AL boxes.
I've had high speed misfires w/ the older Digital 6 Plus boxes and the Digital Multi Retard boxes, but otherwise they ran fine.
At this point, I'm all about keeping it simple. If the 6530 comes back, I'll give it another shot. If it still has issues, it's coming out of the car for good and the analog stuff goes back in...for good.
I'm far from a "serious" racer. I mostly test and tune and run the occasional street car/KOS shootout.
I have zero desire to plot a timing curve. All I want to do is pull timing out when the nitrous is activated and have a couple of rev limiters. That's it. I have all the control that I want w/ the nitrous progressive.
I don't want an MSD Grid or anything resembling Holley EFI on this car. I'm not setting the world on fire here w/ my two ton sled.
If this thing would still do a burnout on 20° of timing, I'd just manually pull the timing out, lol.
The Holley would do it that way...Once a timing curve was built or chosen. They have premade ones you can chose from, and select one of those and adjust from there or build your own. Activating the NOS would pull a set amount that you decide. Talk with Rich, at Fastman EFI...He has done some cool stuff over the years.
You never touch the base timing table once its set. I would do it that way with a 7AL box...I like how well your car performs on NOS, its amazing how fast it is on those little tires. And with the array of sensors, you can log everything you could possibly want to watch. Not everyone uses those as an EFI box, some use them to control everything and keep the carb. Or go all in....
