it is finished, it will be released with the next big Enginuity revamp. (Launch control, per-gear wastegate comp. and ramTune)

i know they where doing some beta testing with launch control on the 16 bit ECUs. if you go on their forums and PM one of the Devs and ask nicely they might send you the code.

We are not going to be passing it around via PM, so please do not ask. We've tested and developed launch control for the 16bit ecus as well as for the 32bit ecus (with FFS). The reason we are going to release it along with real-time tuning is because our version (RamTune) has map switching which will allow you to switch between the real-time tune and the rom (base map) tune on-the-fly (with a specific combination of defogger switch and rpm). So, in order for the launch control to be one of the parameters for map switching and real-time tuning, it has to be integrated with RamTune.

RamTune has been developed and tested on the rom side for the 16bit ecus. The fuctionality and user interface needs to be added to Enginuity, however. We have not started on real-time tuning development on the 32bit ecus yet.

If it starts to appear that RamTune will be a long ways off to being released, then perhaps I'll release launch control and per gear wastegate compensation maps which will work indepedently of real-time tuning. If this is the case, I was thinking that the launch control rpm could be setup to be adjusted as follows (16bit ecu):
1. Rev motor so that launch control limit is engaged.
2. Hit defogger button which disables launch control.
3. When launch control is in disable mode, the "real-time" limit can be set.
4. Rev motor (under the veh. speed where launch control would normally be active) and hit defogger button at the rpm you wish to set the launch control at. Launch control would now be active at the new threshold.
5. You would also be able to change the default rpm for launch control by flashing the change.

The same could be done with the 32bit ecus, but more elegantly since we can monitor more switches such as the cruise control buttons. The only issue we've come across, though, is that with the 32bit ecus and FFS, the ecu tends to end up with negative fine learning correction. When shifting with your foot to the floor (or the transistion between the shift), the ecu mistakenly thinks it is knocking. We'll have to come up with a work around for this before releasing the FFS feature.

Please do not PM devs at Enginuity about testing or to request a copy of the roms. When we need further testing, we will ask for volunteers on the Enginuity site. Thanks!

My personal opinion is release it for the 16 bit ecu's as soon as you can. Just having that feature for some wrx's will bring alot of people over to open source.

So says the owner of a car with the 16 bit ecu ...

Not that I am disagreeing

16bit are the non drive by wire vehicles (02-05WRX)
32 bit are drive by wire (04+sti, 06+WRX, LGT, FXT, Baja Turbo)

I'm curious as to how launch control works with non DBW ECU's. Does it just pull ignition/injection to keep the RPM's at a steady state?

The same way it works with the 32bit ecus - using the normal rev limit fuel cut logic. Since we can't monitor the clutch signal with the 16bit ecus, when vehicle speed is below a certain threshold (adjustable), the launch control limiter is used. When above that speed, the normal rev limit is used. For 32bit ecus, whether launch control/FFS fuel cut is active or not is controlled by whether the clutch pedal is in or not with a vehicle speed threshold for determining the switchover from launch control to FFS (additionally, it would be easy to add an additional threshold for FFS based on throttle position to avoid the fuel cut during normal driving).

I had assumed that you would limit the throttle opening on the DBW cars. Thanks for the feedback.

why do that when you can use the same programming as the stock rev limiter? What you are assuming would take a lot of extra programming, if its even possible. Why waste the time when u can do it a lot easier, and acheive the same OR better results?

Default OpenEcu map-switch ?

A bit off topic but..

Is there a way of fooling the ECU to believe it has AT transmission and not MT ? And vice versa..

The reason I'm asking, is that this would open the possibility of switching between 2 maps.
