Thread: Launch Control w/Realtime

I will just wait until you get that program done lol.

wow im kinda lost.

Cool finally got around to adding this to my XDF. Works great. Thanks

so i dont really get it, what activates and de activates the launch control?

Car speed... 0 to value stored at DFF2, while in that range limiter is pointed to DFF0

Ok I started having troubles with this Bin and I don't know if it was the Bin or more corruption by Nistune... Basically locking timing at 6 degrees. I don't have time to test and isolate culprit so just switched to old base bin. Don't know if anybody else has seen this.

I kinda screwed up when I patched the B14 and accidentally turned off part of a routine. I'm not sure what it did. I'll redo it with the routine turned back on.

Can you test something for me btw? Add these to your XDF (both constants & you may already have the first)-

E065 - Closed Loop Speed Trigger, size is byte, conversion is 2*X (just like a speed limiter)
E066 - Closed Loop Speed Additive, size is byte, conversion is just X

and to Flags/Switches add-

E036 - Closed Loop Speed Trigger Enable, bit 5

Open whatever bin your working with, set the E036 flag, and set the speed trigger to something low like 5kph, and the additive to something small like 1 or 2, and see what happens.

Here's how it works-

The speed trigger is straight forward, above that value and it stays in closed loop. The enable/disable flag turns this function on/off (off by default for the FWD SR ECU). The 'additive' is weird, but I think its really a 'disable above a certain speed' function, but its hard to implement in TP. How it works is it takes the current speed, adds it with the additive value, then if the result is higher than 0xFF it sets it to 0xFF. Whatever the result is is what it compares to the speed trigger. Weird, but I think its intention is to act as a disable function if above a certain speed. I guess you could implement it in TP as

510 - (2*X)

Anywho, let me know what it does.

I will try this during lunch. Adding to my XDF now.

Tried. I noticed nothing different. It still seemed to go into open loop like normal, but I didn't get to drive or check that long. Also not sure if I can really verify status of open/closed loop. I am just comparing with AFRs I know where it should be open loop. Is there a flag that I can watch that verifies it is in closed loop?

Edit: after talking with you on phone went out again. Same deal. I really think need the flag to try and verify.

anyone got a vid of the launch control in use?
