Meth sprays on maps 3, 6, and 7 by default.

To have it hold a specific boost level while in anti-lag mode you'd also need a dedicated anti-lag boost target. Which is also something we're working on adding. The hold up on that right now is the interface. I can't add any more fields without having to redo 10x JB4 firmware versions and confusing customers with firmware to interface mismatch issues for years to come. Which we don't want to deal with.

So to get it done quickly we need to retask an existing user adjustable for it. One option might be to use the 1st gear boost limit field as the anti-lag boost limit value. Another option would be to take the map 6 1500rpm boost value as the anti-lag limit. Both values would limit the anti-lag gear regardless of gear or map, of course.

Thoughts?

As a fellow developer, I'd much rather a declaritive approach and have the interface show what it is (e.g. "Anti-lag max boost"). I think having a version control with a backwards compatible interface would be ideal.

That being said, given the two options presented, I'd do the map 6 1500rpm setting as it is basically useless (PWM is 100 at WOT on spool-up anyway).

Max boost in first gear is still useful independent of anti-lag.

These updates are awesome Terry. We appreciate it.

At some point we're going to have to redesign the interface anyway to allow for the PI integration tuning. So I'm just holding off any major interface changes until then.

Do we have a second on the map6 1500rpm boost target doubling as the anti-lag target?

Same here - if I lost first gear boost reduction my tires would cry.

Map 6 1500rpm boost value sounds perfect to change!

Worked fine for a couple days.

Then it got really cold, in the 30s and then this didn't work. I see that I have to change something for "cold weather cars", I have to go into the flash?

Or do u have a flash for it?

Thank you

Why not use the 3rd gear limit spot? If people are doing this they need to set up their car properly.

Because then you restrict the boost limit outside of anti-lag function

Do some logs of it not working and lets check it out.

Terry if you use the map 6 function, How will this effect map 6 users? Also if you use a stand alone meth kit like HSF4 how will using the anti lag feature work or will it work?

The map6 boost target at 1500 is useless anyway as no one is getting to target below 2000rpm.

Shouldn't be any problem using anti-lag with any meth kit.

Really need to get this and try a 2nd gear launch at the track.

Man for cold weather areas, I have to reflash whenever I want to drive when it is sub 40... I just tuned it out for now, any way to fix this yet? Like maybe switch the iat target to like sub 0, or even 220+?

None of the cold weather guys are willing to provide any logs on it so not much we can do until we see the data.

Not really sure if you need a log to figure it out terry. It's 22* out in the morning, I drive my car on the highway, the iat is 32*. It goes to -25* timing. Anything over let's say.. 70 load and I'm in anti lag timing, never mind if I put my foot to the floor.

Where does IAT go when engaging anti-lag mode when the IAT is 32? We can shift how the JB4 applies the function in cold weather and then you can adjust the flash table so the effect does not kick in until say 20 degrees.

Terry, when do you anticipate having the A-L max boost setting implemented?

I get surge when I try to use this every time.

Thanks

Ok tomorrow morning I will check where the iat drops too. I was under the impression that it was always around 20-21 * iat when holding the button

It's been posted for a week or so under v31.8, bottom of the N54 sticky, for evaluation.

The JB4 is set to do that but we need to find logic that works for all climate conditions. I just don't have any data on sub 40 degree weather cars to consider. Provide the data and we can work on it.

In the northern climates, we would actually have to use below zero, or maybe switch it to above 150 degrees. 20 degrees would still be to close to our normal range. Heck, I can get below that with methonal right now 😉

I think we can go to around -20f if needed. Keep the data rolling.

The ST sticky has to 12_2 firmware as the latest. [edit] I see the ISO firmware, but which version do we use for ST, 12_2?
