Push the pedal harder/longer?

 

Yes lol. I'll also try lowering the resolution to make target throttle ramp up quicker. But I guess that's a 'no' on a separate/hidden map when off load?

 

I haven't seen anything that would let you alter the throttle map when clutch-in but go back to normal when clutch out.

 

Yup.. the throttle maps don't work off of load, simply pedal position. Like you said, you can just increase the sensitivity and see how you like it.

I don't have a problem heel toeing with the desensitized throttle maps. I do have a lighter flywheel installed as well which certainly helps. The AP2 flywheel is the real problem.

 

My suggestion would be modifying the actual pedal. Install a spacer or a thicker pedal.

 

Thanks. All good points!

 

Really don't understand your comment about me not caring about 60% vs 80% throttle. LOL. I care very much.

At higher speeds, you want more control over torque output at the high end of the throttle. The stock tune is setup like this. So when you're going through a high speed kink at 1G at 110mph, a slight lift of the throttle doesn't transfer as much weight as compared to lower speeds where you can get away with a bit more weight transfer for autox purposes etc.


Clearly, you disagree with me and the engineers at Honda.

 

Huh? The "stock tune" very much limits throttle resolution at higher speeds, due to the "ramping" of the actual throttle plate opening more with the same throttle pedal position. You said above "I didn't notice a difference." I was merely saying that I noticed a CLEAR difference and if you couldn't notice a difference, then good for you.

Having the new throttle/speed table allows the throttle to work as it actually should have.. honda clearly flubbed this one imo.

 

I wish I had more time to post about this, but I wanted to share my findings about the new throttle tables. Since I currently daily drive 2 Hondas with DBW ITB's on FlashPro, I have to be VERY careful about upgrading FlashPro firmware. If I upgrade to a bad version of firmware on the wrong Honda at the wrong time, I'm stuck like chuck, so I waited until a few days ago to upgrade my S2000 firmware...

Thankfully, the new firmware worked fine, aside from a relatively minor TPLATE calibration difference. Even better is that the new functionality seems to work VERY well to improve drivability of the ITB's. The drivability was already very good, but now it's really hard to tell it's not a conventional throttle body. The "on / off switch" effect that ITB's are known for is totally correctable!

Here are my current throttle tables, which make the throttle sensitivity dynamic by vehicle speed AND engine speed! At low speeds the throttle pedal is deadened at the low end, and the high speeds the throttle pedal is deadened at the high end. The same occurs by RPM, so the result is a throttle response that is much more intuitive than anything I've driven before. It's definitely more intuitive than any cable throttle system could be.

Note that the stock equivalent tables use a max index of 100, which winds up having the same result as the previous generation tables (4 unused columns). However, if you increase the max index to 144.1 in the throttle index table, those 4 columns in the throttle mapping table become useful, so I took advantage of them! Unfortunately, the index table does not have a column for anything above 90% of the throttle pedal. This means that 90% is treated the same as 100%, which means that the top 10% of pedal travel is meaningless.

Also note that if you change the max throttle index to anything higher than 100 without reducing the max values of the throttle index mapping by an equal amount, you'll throw a hard CEL the moment you push the pedal to the point that the ECU commands anything greater than 100% throttle. Basically, the target throttle map should not have any values higher than 100 unless your throttle index forces the ECU to ignore those columns.

Here are the same views for the OEM tables

 

I guess the question still becomes when it is all said and done. What throttle percentage value actually equates to say a half open throttle plate? If you utilize the full 144% does that mean that if you really wanted the throttle plate half way open at full throttle would you enter 72%?
