Rolling launch control with randomiser (Motec style)

Hi guys. What do you think about this feature?
The fuel cut randomiser helps to the engine to be more stable. As the result, more stable boost can be reached at the same time with fuel cut in random cylinders.
You are welcome to watch my ugly videos about implementation of some features for a stock ecu.
P.S. CEL light blinks because fuel pressure sensor is off.

Rolling launch (activate - with brake switch and tps) This is 3rd gear.

Launch control(activate - with clutch switch and tps)
For compare
This is stock launch control (tephra mod)

This my launch control (only 2900 rpm)

Did you do this with Tephra? I looked through your Youtube and I didnt see any videos about how to, is there anywhere I can see how you did the rolling Launch control and the modified regular launch control?

If you have the disassembly skills then how about adding overrun anti lag with ignition cut & rotational idle
That's the best feature than can be added to the stock ECU!

Yes, I can make this features. But for the antilag, it is necessary to supply air to the exhaust manifold

I'm not referring to the SAS system found in Evos, I meant 'Motec' style anti lag with a throttle kick. With throttle kicked at around 20% or more TPS rotational idle is needed to prevent the engine from hitting the rev limit. Negative timing along with ignition cut would help build up boost while enough air & fuel is being pumped through the throttle kick.
Sadly, such features are available for the Subaru stock 16bit ECUs but not for Evos... yet!
