Smooth Throttle for UpRev

Shamrock · 12-19-2012, 08:08 AM

Wstar are you saying to try the curve 2300 as opposed to the older "linear"

wstar · 12-19-2012, 08:42 AM

I was, yes. I've been running the Curve2300 map since I added that to the first post over a year ago, and it works great for me. The previous map I had published (which is Linear on the charts in the first post now), in practice produces a surge of responsiveness in the upper range of the pedal followed by a flat-spot, so it's just not as precise, predictable, and controllable as the Curve2300 one. The point of the Curve2300 map is to (a) solve the "ECU doesn't fully open the throttle at low revs" problem while also (b) providing a smooth, predictable response so that you can do nuanced throttle work and not be surprised by variations in the effect of a given amount of pedal travel in different parts of the range.

All of that said, though, none of this work has been updated for UpRev's latest findings a few months ago. They cracked at least some of the real VVEL control tables, and this mystery throttle table is undoubtedly tightly linked with those, and they probably know more about all of these related tables than they used to. At some point I need to take a look at what they've got and what it means for all of this.

If you are referring to the throttle table above it has nothing to do with VVEL this is what I came up with to counter measure the bad throttle response below 2200 rpm,all I did was to get the throttle blades to open quickly.

They're definitely inter-related, since VVEL is what's really doing the throttling. Part of the reason the understanding of the throttle table was fuzzy back when I was working on this was precisely because the VVEL stuff wasn't yet figured out. I imagine someone at UpRev now understands the throttle stuff much better than before.

The version above is a modified from yours and fixes all low speed issuses I just haven't found out how to get the Hex code on the site yet.

wstar · 12-19-2012, 04:23 PM

Yeah I have yet to see any version above, just blank spaces in your posts, so I have no idea what we're talking about

You don't see the throttle map I posted?

shaun66 · 12-19-2012, 07:22 PM

I don't see anything either.

Shamrock · 12-20-2012, 06:45 AM

Nor do I

Ok yeah I can see the pic of your map here. Any details on how you arrived at those values and/or the intent, etc?

I kept your 3800 row the same but everytime I changed a top number (800 RPM)I changed the whole row to keep the row the same from 800 to 6800 RPM.
Your 2300 map is good I have driving around with it for awhile,all that was needed was to get the throttle blades to open quickley,so I got them open quickley and then brought the cruve back to roughly the same way you had it in the 2300 map.
When you have this map in Osiris and pull it up in the 2 demensional map and do the same with your 2300 map you can over lap them and see extactly what and how I changed it.

Hex code finally up for my throttle map.

Shamrock · 01-21-2013, 03:24 PM

What is your throttle map?
