Rolling anti lag

Post by 93supercoupe »

So i tried roll racing a brand new GTR the other day, and the only reason he got in front of me is because he out spooled me. I tried brake boosting but it isnt relaibale enough. So i was thinking of rolling anti-lag.

I was thinking if we could use an activation switch, and have NO defined RPM. So when you hit the switch, it would use the current RPM and implement the settings you have in the anti-lag feilds.

So basically exactly it is now, but not requiring a RPM. Just when you hit the switch, it just keeps the car at the current RPM? and allows you to load it up?

Is that possible? Maybe can be added to the next firmware? Talking with EFI analytics they told me this would have to be done on the firmware/MS side.

I reached out to James about this, but i wanted to see maybe theres a way to manipulate what we already have to do this?

Any thoughts?

thinking about this more, you wouldnt really need to implement any timing retard or fuel enrichment but just a RPM limiter that activates on an input at any RPM.

So is there a way to use the flat shift function? variable launch?

But then how would u maintain a steady speed?

Couldn't you abuse speed based launch control to limit your speed and rpms? Use a switch to activate it and disable it to launch. It even has retard if it would be useful.

but you would need a defined RPM.

What im suggesting is just have a switched Input that when active, limits it you to its current RPM.

Thats basically all im asking for. Hit a button, and it stays limited at its current RPM.

I generally race from a standing start, so don't have much use for it.........

well im sure im not the only turbo car on here that likes to race from a roll. Not every car i see on the highway that wants to race is willing to stop traffic and go from a dig.

what about using the variable launch with a potentiometer and can just wind the rev limit up or down like a volume control.

My apologies!

I actually did understand your question. As I get older, I seem to be tiring of picking up the pieces and dealing with the aftermath! Perhaps it's just the 38 years of cop in me.

Race on! I just hope no one here is a victim!

I would have to agree with the street roll racing, but on th same account i have attended roll race events at airstrips before where it's 100 over your start mph and would be trick to use my linelock button on the shifter to maintain say 30mph in second with a little retarded timing possibly building a mild amount of boost

Hey Nate! :D

If there's a need, there's a need and I have no intention of disparaging that need.

Probably over reaction on my part! :oops: But what I said is based on a whole lot of real life experience and my genuine concern for everyone.

Take care..... and above all..... Be safe! :D

Yeah, I once had some terse words with a street squid about the difference between 'street racers' and 'road racers' - road racers drive up my adrenaline, street racers drive up my insurance rates! :x

Ken,

I don't think you're overreacting. Being concerned about the safety of people who don't choose to be in a racing situation (with all the risks associated with it, and more so in street racing) should not be a difficult thing to understand. But it isn't as obvious to everyone apparently.

The feature could be setup side by side with the 3 step feature. Have it sub programmed for vss = 0 use burnout revlimit, then if vss above xx mph then capture current vss or rpm and maintain using x timing when tps above xx%

Why not setup the als properly. Just set the minimum rpm to something like 2000rpm.

It works exceptionally well. I scare passengers with it all the time. Off throttle from 3000rpm i see 10psi of boost.

You need an air bypass valve or a throttle kicker, then setup the als options as needed.

Or do what us rally boy's do. Left foot brake....!!

LOL im not coordinated enough to left foot break consistently.

I think we are taking this entire thing out of context. All i want is the ability to load the car while rolling, at any RPM. Can we do this?

PS- i am not a street racer. But im not an angel either. I dont condone street racing, but there are other places a feature like this can be applied.

Other systems already offer this feature.

with out seeing what you are talking about, the Antilag that is already in the MS3 will do this.
