Maybe its hitting a similar function triggered by the throttle being 100% and or clutch-action (as reported by the clutch pedal or TCU).

That could be a consideration for V2
Yes could be, the GSR has the lower bound set to -20 over the whole table. Not sure if the table is called on the GSR though. What does your log say ?

I am considering releasing a V1.5 (just to include the lower timing limit altmap) - let me know if you guys would like this.

What about gear based MIVEC - ProTuners - is this really necessary?

I see that Cobb will be implementing KnockCEL... very interesting!

I'd like to see gear based MIVEC, for sure.

Yea no ****, cool they can steal your work That is ridiculous.

Edit: They need to accpet that they cannot keep up with ECUflash....

They just need to die on the X platform, no longer needed.

I wonder how many of Tephra's newly found tables will be in their update?


Gear based Mivec:
If you can keep the warm up tables, then yes. If you are going to use the warm up tables for low or high gear range, then no. Gear based boost control is all you need. People just need to learn how to use it. Actually, proper tuning of your Mivec will prevent surging in any gear. People just need to be realistic with their tables. (You are not going to spool an FP Red at 3000 RPM, so don't try... problem solved.)

What is the reasoning for separate warm-up MIVEC tables? The IX did not have one so I am just curious.

The X has not the EGR valve, but "produces" EGR using valves phasing (in reality, in this case it's not so correct to call it EGR since there's not a true gas recirculation). So, I think this can be one reason to have different MIVEC tables during warm-up, where having high EGR ratio is not required for emissions and can lead to combustion problems.
Then, using different valve timing you can also get higher EGT: this helps (together with other things like using less spark advance, etc.) to warm-up the cat faster.

I've had locals with good success eliminating surge with Greens while maintaining a good spoolup. I don't need the gear based tables myself (yet), but I know they can be quite beneficial.

I agree on having it done properly though, maintaining the warmup tables.

Racing, I'd like to see gear based MIVEC...

I think it would be very helpful going aggressive first 3 gears and then going more tame with 4-5th gear. Also adding different MIVEC settings for alt map would be helpful.

The IX didn't have adjustable Exhaust Cam timing.

If the Cam Timings are aggressive and the car is cold, it drives like crap and bucks.


therocket:
It would still be called EGR, it's just done by allowing exhaust to re-enter the chamber via cam timing. But yeah, no valve. This is really nice, because we can eliminate it when we want.

As golden said, gear based boost would be good for all street usage when issue arise or to fit people request/bigger turb/etc.. etc....

Yup that's really lame from them

In the end they will say you did a copy of what they did first, like it was in development when you released TephraMOD X V1

I'd personally like gear based MIVEC and or a more gear based boost.

Gear based MIVEC could help me keep my noise down a bit on the highway (yes, I'm serious... I need to do more testing but this makes my buschur bullet a cop magnet) and gear based boost was always much better for boost control (though the 3d tables on the X are very smooth at part throttle)

Tephra, I'd hate to say it but it might be a good idea to look into some kind of creative commons licensing or something. They shouldn't be able to sell something you have created without AT LEAST giving you credit.
