Ugh. At those temps, yup.

I dumped my tires in a week with my last F90 because of traction. It ain't cheap, though.

Yup the temps have sucked . Today was mid 60’s so it was nice.

I like the 20inch OEM wheels. Is it pointless putting bigger tires on these wheels because of the width?

Nope, the rears are 10.5"--perfect for 295s. Fronts are smaller and fit 285s nicely. I've run this setup for 28,000 miles on 2 x F90s and nailed repeated sub 2.6 0-60s and 10.3x 1/4 miles--it works beautifully on the stock wheels.

Oh perfect, because I have no interest in replacing the wheels.

Likewise.

Thanks!

295/30/20 rear
285/30/20 front

Michelin PS4Ss.

34psi ambient cold @~45f

However, in light of riding 35% profile stock tires during my 1,500 mile drive back from CA, I'd recommend preserving the 35% profile especially if you have or will lower the car with aftermarket springs, etc.

How do I buy the license for my 2018 bmw m5 I cant seem to find it on their website

Luckily I'm local to them so I'll be leaving the car to them once this cornavirus blows over. Once they develop support for 2020, they'll release it for everyone.

Even had a little slippage with this run

Don't hold RPM Launch too long

First try is never the best unless tires are at good temp and good pavement.

Tire pressure and temp are important, too—do you know what they were during the run?

+1
Tire pressure is everything!

Also this was on little to no adaptation. These OTS maps are smooth as butter but I'm sure there is still some adapting that needs to happen. Well done Bootmod3 this was well worth the wait. Can't wait for stage 2

34F cold all fours

Flashed BM3 on a F90, OTS Stage 2 9octane, the car is killing it, perfect drive and power delivery.

Dragy is constant 5.7sec 100-200kmh. Owner is very very happy.

Congrats!!

Would you mind flipping your Dragy into prehistoric imperial units and maybe get a 60-130, 1/8 and 1/4 mile, etc.? I'm always interested to see the advancements in the ECU tunes.

PS: I think there's a digit missing from your pump gas octane, what was it?

Here is the dragy:

https://ibb.co/rd5m1H8

This was 93 Octane(98RON) map. Will do a few logs to see with HCP can improve a bit.
Did a few F90 with HCP and all were rockets, doing 10.3 1/4 mile and 5.5-5.7 100-200.

Everying was done on pump gas.

[bm5bullit]

Most excellent results!!

[JBA87]

What is the equivalent 60-130?

Super solid results!!!
Post the 60-130 as well so the US folks can see thanks for the post

Cheers

Nice

I can't close on this with HCP on my car ...


I think I have an issue with my HCp Stage 2 file

I do 60-130 on good fuel w and e85 mix of 7.2


My other tunes do mid to upper six pretty consistently

Sent over some logs

Hoping someone at hcp can diagnose the issue

I have flashed a few F90 cars with HCP over the year and all run perfect and very strong.
A Stg1+ HCP with just a tune and opf delete does constant 5.9-6.0 runs. Just on pump fuel.
And our fuel is not near good as Shell Vpower or Aral102.

[JBA87]

On a 60-130?

I find that hard to believe

Hcp Tells me they are not aware of any stage 2 pump that does less than 6.8 seconds

[JBA87]

Do they have posted dragy times?

I think what people tend to forget is ambient temp is very important if not the most important when considering time.
