Default Car Hits Rev Limiter under WOT?

From a standstill and go WOT, the car take a long time to shift in to second and third and bounces the rev limiter like a MF! How do i fix this so it shifts better as soon as hit hits redline?

Post up your tune, as well as explain your desired shift points. This should yield you your best possible results from the forum.

The table "Fuel Cutoff RPM vs Gear" is set to cut fuel at 6300 rpms. Tweak this table if you want to shift at 6300

You always need to have the engine Rpm limit higher than your shift points.

that would be the easiest solution, but is it the best solution for the powerband of your car and getting the most out of it? Only you and the dyno know

Both the mph AND rpm must be met before a shift can happen. Did you try lowering the mph?

Try,
1-2 33mph
2-3 64mph
3-4 108mph

The MPH for the shifts I've commanded are met with your gears at 5100/5200/5300. Big stalls kind of make this part weird to tune, so bringing the mph required low ensures that when the target rpm is met, you shift there.

You can also increase your rev limiter to 6400, and probably squeeze by.

Bro-take the whole shift mph table, hi-lite it, punch in -2 then click add, this will drop each point by 2 mph. Raise the rev limiter to 6500 as well-make the changes then email me the tune.

+1 on the lowering the mph, I pulled all my hair out before I figure it out last year on my car.
