Hi all, It would be really cool to have an adjustable (re-activate) launch control..
i dont know how it works but i can guess....

if SPEED= < 8 , rpm limit = 4000, IGN re-activated at 3500..... this seems to be the case, causing a slow whimpy launchcontrol... (bhaammm...bhaammm. bhaam.....)
actually cant even give me 5 pound of boost :S

it would be usefull to have the RA.TATATATTATATATAATA!!! launch... :)

Please please please add a scalar to the Closed Loop function.

Right now I see
Off
On
Off in boost.

Can we add a "Off above XXX kPa/mbar/inHg/etc"? My car acts all goofy since it SEEMS to me closed loop in the ODB0 code is more dependent on TPS (?) than MAP. It wants to run me in closed loop all the way up until 0 vacuum.

Before I had it set to "On" instead of "Off in Boost" and it kept leaning me out to stoich at half throttle, even at 10psi of boost (!!).

My understanding of how it works is that it is it goes open loop at above about 60% TPS. Which, on a healthy engine, is going to likely be near 0.

That would make sense with what I am seeing. I use my wideband as O2 input and it's programmed to output 0.45v at about 16.5:1. It works great lean cruising but my car does not like 16.5:1 at loads above 8" or so vacuum.

Unless you are using a simulated narrowband output, you cannot use a wideband as input in closed loop.

I got your emails and will reply later.
