Two step using Uprev on a boosted and NA 350z
 

Had more time to play with these to make them work properly and be safe.

you are selecting a non used MAP that is just this option? cant think of anyother way around it

What is the point of this post? Free advertisement?

What is with people on this forum? It's to show that Uprev can make a good two step. **** I'll post the maps if I have to so you can do it yourself... christ. Set Rev to 4000, timing to "00" at 3600 and up, fuel comp to "125" at 3600 and up, fuel target to "10" at 3600 and up. Happy? Now quit bitching.

I am using Map 2 for the two step function and Map 1 for the regular map. Easily switchable while driving or when preparing to launch the vehicle.

i would be a bit worried about high temps in the headers, but i guess every once in a while it wont hurt

Mad props for not only coming up with an actual way of tuning a 2-Step on UpRev but even more mad props for sharing this with the community since you technically didn't have to. I also like how you showed proof of concept through actual video.

Most videos you see out there of UpRev 2 Step was just your typical rev limiter setting which really was a bit scary since it's cutting out fuel. With your way of tuning it your enriching fuel prior to cutoff so if anything it will be cooler on the system even though flames come out. I had thought of doing this very same thing with a friend of mines who's way better at tuning than me but we never really got around to it. I normally rather Track my care on road course so there was no real need for it but it's a cool option to have for those test and tune days at the 1/4 mile on events.

So would this technically work at different RPM setting just by shifting the numbers say for example I'd like to setup my launch at 3000rpm:
-Set Rev to 3000
-timing to "00" at 2600 and up
-fuel comp to "125" at 2600 and up
-fuel target to "10" at 2600 and up

I see you set your Rev Limit Fuel Cut Off at 4000rpm. So what rpm did you set your Fuel return at?

so to actually drive this, you need to have your hand on the shifter as well as hit the cruise control button to shift to map 1 to exceed the 2 step rpm?

Sounds safe and simple.

Actually, all you do is switch with cruise control to 2 Step map... Then switch to the map you want to race with but hold the Coast/Set toggle switch down with thumb. With UpRev, you can pick a MAP to switch to but it won't take effect till you release the Coast/Set toggle. WOT, take off till you catch grip and release the Coast/Set toggle. As soon as you release the toggle switch, the car goes to race map. It's real easy to launch this way and gives way better and more consistent launches especially to those of us with MT. If you're FI and MT... you can't build up Boost off the line unless you have a 2 step. The original method with UpRev that most were using was simply setting up a rev limiter on uprev which is ok for N/A but won't build much boost with FI. With the tuning setup shared by OP... it's actually functioning like a real 2 Step by retarding the timing and letting some fuel pass by into the exhaust. Also since it's adding extra fuel it should keep the pistons cooler vs simple fuel cut rev limiting. One can further fine tune depending on how quick you want to build boost for launch.

Thank you very much for this! Now I can use 2 step for both my NA and turbo Z's

Fuel cut at 4000? Fuel restore rpm?
 

What is your fuel cut/restore set at?

Normally Uprev recommends a difference of 100rpm between Fuel Cut and Fuel Return but you can play with it to see how it responds with OP tune.

Anyone else tried out this set up?
