Does the one with traction control really change much, unless you have a traction issue? Take care. Tom Worthington

Nope. Same as the MSD 7531, no traction issues, no advantage to using one. I doubt it's accurate enough to "ride the dots" and make the car/dragster run the exact dial all the time.....

Get something to "see" the tree to control the start of the race, I think that's where most of the race takes place. Seems a lot of cars/dragsters don't have a big issue repeating in the 1/8, the 1/4 is a little different, especially with wind.

And what about the Davis unit that’ll plug into Dominator EFI? Does this set any tattle tale of prior use?

You can use the Davis Box as an add-on to the Holley system, or simply use their traction control device.

Either way, it will be in the Global Folder (which has ALL the tuning params). So, unless someone doesn't datalog the run, and uses a small notebook computer or one of the Holley Touchscreen Displays to swap a "normal" setup into there after a pass, anyone with a laptop and the knowledge of the Holley EFI system could tell there was some "cheating" going on!

Those are some pretty impressive numbers and I think they make a statement. As far as I know, no one has ever had the nerve to suggest there is cheating at a practice tree race. Take care. Tom Worthington

I counted 10 redlights in 51 runs or almost 20% red.

Definitely not cheating.

How many brands of ecu's with different software can you come up with just off the top of your head? I can think of more than a handful. So tech folks need a laptop with all the different softwares to check this stuff. People have been claiming cheating for decades. But the efi software has come a long way in the past 5. Really it's up to the user to have the determine what features are not legal and for them to have the integrity to not use them.

Bucky, I gotta ask. Is any of this software doing anything other than controlling a traction issue? From what I'm reading, it kinda sounds like that is all it is. And if all it is doing is taking away power to control a spin, isn't that going to adversely impact an ET prediction also? Take care. Tom Worthington

Practice tree races are a different animal. You're basically set up to be perfect, particularly in an event like this that was Best 2 out of 3... gives you some wiggle room to be more aggressive. Note that 6 of the 10 reds were -.002 or -.001. "In real life", you'd probably adjust at least another .005 into it, if not .010 or more for bottom bulb or footbrake racing. The last year that I did full-season stats, my reds were 11%. Still too high. I'd like to see it around 6%, but my car isn't where I'd like to be. Made some changes over the winter to try to get it to react better. Real-life green light average is usually .017-.020 for a season.

At the Christmas Tree Extravaganza practice tree race in December, I got to Rnd 6 of the Bottom Bulb race, and was runner-up in the Top Bulb race leaving off the bottom. 10.9% red, .011 green light average. I did try leaving off the top once and was .055. LOL Went back to the bottom and was .003, .004, .001, .000. I did have a .040 in the semis where I COMPLETELY failed to let go of the bottom, and just got lucky that the other guy was red. I did the same thing late in a couple of other practice tree races, too. smh... Brain's gettin' rusty.

I'm proud of my stats, but the important takeaway is that there are numerous guys that are demonstrably BETTER. There are some incredible talents out there. That's just how our sport has evolved, and the serious level of training that some people do.

I highly recommend Luke Bogacki's ThisIsBracketRacing Offseason Practice Tree Challenge. It's a free facebook group. They do two weeks of drills for bottom bulb, and two weeks of drills for top bulb. It WILL make you better. It's done for the season, but you can go back and review any of the drills from this year as well as previous years.

If you designed your own device, could it be capable of more than just controlling traction loss? Take care. Tom Worthington

That's already been answered Tom. Yes it is the same software and function. The idea is to map rpm on a normal run, and create targets for rpm for the entire run. And make these targets slightly less than a normal run. So it is always running restricted slightly by the timing. Ideally, the system has enough resolution to repeat within a tight margin....tighter than you could normally see on most competitive cars. This is all theory, but is exactly why the slew rate controllers were outlawed for bracket racing. But frankly, I don't know anyone who has shown how good the resolution is on the slew controllers. It isn't exactly something that those using it want to show off. And not something that those who aren't, want to invest in or be connected to. I thought I remember a contributor here....thought it was Jok, writing an article about slew rate. And I thought a test was to follow. I never saw the follow up.
So it exists, and just has to be hidden.
But, what a lot don't realize is that the msd's aren't the only ones that have slew rate in their software. I really don't know what can be done to police this.
