what AFRs should i be targeting during the 2-step?

i've tried searching but only found info on timing for it.

 

altho, Im trying to have the longest lasting stock clutch , so dont launch much, but remember seeing something bout wanting ~10.5 afr. 9.5 in the map is what Ive got mine set to, but like I said, havent tested it out, yet...
From what Ive read, u want it on the rich side, but no too rich, or it will bog off the line...

 

info much appreciated.

i logged the 2step today and it was knocking a lot. so im trying to work with it.

 

You'll want it fairly rich to keep EGT's under control. I'd target ~10.5 as well.

 

Although this may be far from optimum, but this is how I have my maps setup and they work very well for me.
I have my 2-step set to 6250rpm and I build about 15-16psi quickly. Even though these are the launch maps, I still smooth the cells leading into and out of my target 2-step rpm. I believe this reduces the risk of knocking when transitioning from your regular fuel/ign maps into the launch maps (I've never seen more than 1-2 counts)
Hope this kinda helps.

 

do you have a pic where i can see the load cells too?

the launch maps, the ecu automatically switches to these when they sense 2-step, and then switch over to regular maps once you go?

 

Here you go:




Yes the ecu switches to the launch maps once the TPS parameter is met and switches off (moves back to the regular map) once you lift the clutch and deactivate the clutch switch.

 

Thought i would mention that you have to be running a Tephra V7 ROm to have launch maps, otherwise you are just using your regular maps durring the 2step

 

yes i am aware of that

 

just making sure

 

i've started setting up my v7 ROM with SD. I am just waiting to actually finalize this current tune perfect before I move on to that hurdle.

 

Post your map and some feedback once you get setup and try it out.
