Now this could just be me but the instructions on the Tomahawk are not clear on how to perform the crank relearn. So this is how you do it.

1 - Make sure the car is fully warmed up. Has to be above 160deg.

1 - Follow step 10 in the Tomahawk manual. This takes to you the relearn function.
a) Goto Diagnostics
b) scroll to Profile Relearn - Enter
c) follow instructions on screen - this is where it becomes unclear

2- When you get to this screen notice the ECT (F) temp - needs to be greater than 160

3 - blip RPM - means rev the engine to slightly over 4500 RPM. You don't have to hold there. Just a quick rev up..... or "blip", who knew?

4 - Within a couple seconds the screen should show complete.

If you do not complete the relearn you will get the following DTC which can only be cleared by performing the Relearn successfully.

Does you "down count" ever get to zero?
Mine will say "complete" with count of 2

What is this tomahawk tool? I’ve never seen that before. I imagine something new for 2018 and above?

It's the tool that comes with the Gen 5 Whipple(2018+) to load their tune(s). It also can perform a limited set of other functions, such as crank relearn.
