So i was thinking after reading bout walked U's runs etc. Would it be possible for a V2 map that does not have boost decay? For people who want that little bit extra/dont mind being on the edge? I think it would be nice to be able to run it for those drag race situations.

I am also curious to know how the boost decay works. What does it base the conditions on? Some peoples cars who have more mods like IC/possibly upgraded oil cooler/radiator I would think wont need as much boost decay if at all. It would be nice to have a map that doesn't have boost decay for these reasons. Sometimes i would rather push the car hard and then let it cool off "manually" vs having it done in software.

What are yalls thoughts?

From Shiv's other post in regards to 2.02...

"Boost decay rate with respect to time under boost has also been reduced."

When I read that it seems as if the longer time you under boost the more it will decay it.....

I am sure someone else will chime in.....

I tested 2.02 on the track, with 20-30 minute sessions.

My terminal speeds on the straights did not change over the various runs. The caveat is that my statement means that I'm within a few mph since when you're doing 140+ and trying to slow your ass down before the curve, you aren't staring at the speedo.

I think the boost decay feature is a good thing.
Sure it was a bit obvious that after about the 4th back to back 40-130 mph run with Walked U's car the other night, it was pulling back timing as by the 5th run, his car seemed to be slowing a decent amount.

But keep in mind, how often are you doing back to back to back to back to back 40-130 mph WOT runs with literally about 20 seconds in between each??
Even on a track, you have a lot more braking time and aren't going from 40-130 too often (usually on the one long straight on the track).
And on a drag strip, you only do it once every 2-3 minutes at BEST, and more often once every hour.

Personally, I'd rather have the boost decay feature to save the engine a bit rather than being able to do 5-6 back to back 40-130 mph runs without it.
There really was no reason for Walked U and Terry to do more than 3 or 4 runs anyway. It was clear at that point the cars were even.
Terry seemed to be able to pull a bit by the 5th and 6th run though, since the boost decay feature in v2.02 was in full affect.
Better safe than sorry at that point.

I agree the boost decay is a great feature and will run it 99% of the time... but it would be nice to have the ability to not run it that 1%.

Also when people get their cars modded to handle higher temps etc it would be nice to not have it as much. Maybe have it an option like the boost %. Normal boost decay half as much and none? If someone has a car that has an upgraded IC,oil cooler, radiator they dont need to worry about the heat/wear as much. Maybe if possible setup the boost decay to run on engine temps or something along those lines vs time at full boost?

I was just going to start a thread about this "issue".

Even with less boos decay for 2.0.2 map, Walked U was still complaining that after a few back to back runs, he car felt like v1.47

I am wondering if Shiv can give us a map with:

* - Low boost decay
* - Low detuning

Shiv, Eugene...any thoughts?

[e.n335]

Let's get everything working stable before U try to break new records.

My 2 cents.

There was mention at some point of a few different v2.02 maps. 1 with oil cooler/ 1 without with different decay rates...

I'm OK with the current decay feature. Doesn't appear to affect my laptimes from Lap1 to Lap9. That said, the track is an absolute torture test on the turbos.

For an average 25 minute session, you are on brake less than 1 minute total. If you aren't threshold braking and are spending more time on the brakes, you are going to be slower than ass.

I'd estimate 80%+ of the time on track, I'm on full boost. The PROcede calculates boost decay based on average solenoid duty cycle (per shiv). The only point when I'm not on full boost is in the very very very short braking period and then approaching the apex. After that, it's all the way, all the time.

Ya I think shiv will be working on all the nice fine tuning for everyone. Like Micheal said the boost decay feature is for saftey.

I really do beat the crap out of my car. I feel bad since I don't give it time to rest sometimes. All it takes is 10-15 secs tho of cruising I have found to get the power back. But at last all i have is a beta.

Trust me the boost decay isnt nearly as harsh as 2.0.1.

Im just a picky autobahn racer..... I do like 15 back to back runs

True, but that often depends on the track too.
There are some tracks where you can't go WOT when exiting every corner, or in a tight chicane, or a decreasing radius bend, or opposite angle downhill sweeper, etc.
In those cases it's smooth and steady throttle not just balls to the wall, or you'll be car to the wall.

I know it's tempting to want to do 5-6 back to back runs (40-120+) in as short of time as possible, but the better thing to do would be to do 3-4 max then give it a rest for a bit, then do a couple more if you want in the opposite direction (if possible).

Personally, if you get 2-3 good runs where it was fair and both left at the same time and nobody misshifted or anything, there's no reason to do more.
If someone jumps or missshifts, end the run, there's no reason to continue, as it won't show a true outcome anyway.
Plus no reason to press your luck past 2-3 good runs.

Shiv is just protecting himself too. Don't want to do damage to an engine and have someone say, "my engine blew up because of the PROcede" or yada yada. That wouldn't do customers or him any good.

yes, but if you have a FMIC, and an oil cooler, aren't your harsh conditons actually less harsh than those that are stock?

Exactly! You may be pushing the car hard but you have improved "safety" hardware so the software doesnt need to hold back as much.
