Cool!

Now I remember why I didn't go through with it. No cruise control...........I could care less about SRM, but I am kinda weary about giving cruise control up. None of my S13s had it. Come to think of it, none of my other cars had it except the Tahoe.

However I liked the ETC off. Wonder if uprev can have it moved to a selected map rather than global setting so we can get a choice of turning it on or off on the fly..

Ah, mmmmm... Looking at your car's list on your profile, I wonder why? The EX35 is like a Honda Del Sol performance wise... :roflpuke2:

I asked him to disable it so that the throttle control would be more like 1:1, but he said that it didn't work that way. I hope he was wrong and that does work for this application, but that would be a bit frightening if he would make a mistake like that AND he has been tuning my car for quite some time now.

I'm pretty sure ETC can be on or off for separate maps -- easy to test.

Note: Okay to turn off for MT, but not so good for AT. Seems to put more strain on the trans during shifts.

:iagree: Not good for AT , did that last year and it sucked!

it is under "settings".. and not under throttle menu :(

Good to know about the ATs. Maybe that is why Omar was quick to say that it was a nogo. My maps are locked from UPREV anyway AND I am no where near my car to test the theory.

Oh, crap -- that's right.

Never mind...

I've also been told by Mark@Abbey Motorsport (UK) that ECT off cannot be done for one map only but is a global setting.
I wish it wasn't true

I have a Tuner version and yes it is true! It is one for all Map setting.

If you want it off, just PM me I can do it for free! Pretty easy to change it as long as the MAP is not locked.

Yeah the table still doesn't make intuitive sense to me though. The tuner I used (as in, the dyno-tuning professional) seemed to know what he was doing and set all "3800" values in the last few columns though, and that seems to correspond to WOT at full pedal.

It's clear from experimenting that this table does affect how the throttle reacts to pedal input, but both of the non-obvious labels seem like secondary effects. The position of the throttle butterfly will determine airflow, and that combined with RPM is pretty much going to define load or driving force or whatever. It just seems like one of these axes must be mislabeled for this to be a throttle table.

Maybe this will help explain driving force values
Car Physics

After trying all the maps except the Awgd8 blend 2/3 map (thought i loaded it but i didnt), here is my feedback. Bear in mind that this is my daily car, 6MT and i drive pretty sedately but like to make sure the Z gets some respect at the lights.

wstar smooth throttle: Improvement over stock, too smooth for my likings. For those who have followed my lengthy random loss of throttle response posts, i think this map is the cause of all my grief and pointless searching. No discredit to wstar at all, but after switching for the Awgd8 maps i've clocked 1200 faultless kilometres. It was very weird because i ran the wstar map for ages then all of a sudden the throttle started acting up and required a restart to cure. It got so bad that even a few minutes after a restart it would act up. Then it became every time i drove more than 20mins. It went to the dealer, they couldnt find anything but it didnt come back for almost 2 weeks then it came back. Then it became really random. Anyway, i'm glad to be enjoying my Z again.

Awgd8 v1: Improvement over wstar's map, more pokey but it made me crave more.
Awgd8 v2: This is my favourite. It rips hard from 2200rpm upwards. Screams by 3000rpm and really wakes up the intakes and exhaust.
Awgd8 v3: Similar to Awgd8 v1 in normal street driving. Pretty strong and keen from mid to high rpm. But the low rpm range of this map just doesnt have the punch of v2. I will load the blend map in a few minutes and give it a run.

Thanks to everyone for their contributions to thia valuable thread!

So how many of you are using this modified mapping?

That's potentially quite useful, but a lot of math.

Are there any calculators that might make it easier to apply those ideas to the uprev tables?

I guess one could be made in excel...?

I have been using my MAP 2/3 blend for a while now. I specifically created those AWGD8 maps for my 5 speed A/T 2008 EX35 VQ35HR crossover. Some members here used the map I made, but it could only be felt the difference on the Auto tranny. For Manual tranny, the majority feel the best improvement if they just turn off the Electronic throttle Map setting via Uprev.

I am surprised that it worked out for the manual. Did you try turning off the Electronic throttle control via uprev? I heard this is way better performance if your car is Manual. So basically, when you turn it off, you are not using any of our Throttle Mapping, but direct 1:1 from pedal position and throttle opening...
