Thread: stepdown harness and calum rt= no launch control?

Anyone using a stepdown harness have issues with Launch control?

I have a b14 with the obd 2>obd1 stepdown harness
b13 rt v1
ecu reads speed checked via ecu talk
clutch switch hooked up i believe cruise is also

i have an automatic engine harness but im not sure if that would matter at all.
the launch rpm and speed are set in tunerpro rt and uploaded to the ecu. Ive tried 2 lc xdf and 1 of them froze the ecu. any help would be appreciated.

Do you have an actual bin with launch control enabled?

The XDF won't make the changes to the bin that are needed.. it just gives you access to the launch RPM and speed.

that i am not sure about, how can i find out?

Well, if you started with a stock bin or something that didn't have LC in the title, I doubt that it is in there.

yea then im sure thats my issue, i do have a stock de bin that has lc, how would i go about getting the lc on my vet tune? would i just have to copy and past everything, or is there an easier way.
