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.

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?

I don't see anything either.

The picture is fixed shaun66 pm me and said he can see it now.

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.:hello:

What is your throttle map?

Go back to post 145 it is all there.

I've been following this thread for a while and my mind has been blown. I've been driving around with ETC off and the throttle is definitely more responsive. The UpRev guide describes ETC off has adjusting the Throttle Control Map to linear. Since your graph in the first post shows that the 2300 curve delivers more response in the mid range, wouldn't this be a better feel than ETC off?

I've copied the 2300 curve of your's and Baer383's 2515 curve and can't wait to see how it feels compared to ETC off.

What are you using to judge "better"? I haven't tried any of your maps (or messed with mine) in a long time because I was happy with how mine felt. Lately I've been doing some reading on race tuning in general and it's gotten me thinking about throttle response again, and I'll likely start playing with this stuff again in the next month or two.

What I found in one of my books that makes sense was to setup the throttle with a "Rising rate", where the (smooth!) response curve is inverted dramatically from how my Curve2300 map looks. Basically you drag out the lower part of the power curve over a lot of pedal travel, and then ramp out to full throttle fairly quickly near the end. The reasoning behind this is that you tend to be at neutral/light throttle settings when you really need fine control, and this gives it to you under those conditions. My goal with the previous map was just smooth predictability throughout, but I can see how it would be better to favor making it easy to fine-tune throttle position with your foot in the low range, sacrificing some fine control out in the, say, 75%+ throttle area.

What I mean by better is "my map"
My map gets the throttle blades to start to open up very quickly to remove any lag in the low end off of idle my curve isn't much differant than yours just my throttle blades open up faster than yours.
