Yes. Unfortunately, I ran out of room. Look at the mile per hour as well. Only 115 mph. I'll repeat it when I get a chance. I'm interested to see how much better it would have been if I didn't lift. This is the first 11 second quarter mile I ever did with massage seats going.

Jesus that's moving. I think Carbahn is only 3psi boost IIRC. Throwing 6psi at it with intake and exhaust should be in the 10s easily.

Lol, yes it's a 540i with jb4 and 4psi map. Waiting for my Remus catback, then will do one more run on map 3 (6psi) and a light e85 mix.

Those are awesome 0-60's. What are your 60fts?

Amazing. Great job!

Sweet. I'm seriously interested in seeing how many miles you're able to get on that thing without any problems. I don't wanna jinx you, you're doing a great job. It's just a curiosity thing.

I've been drag racing since the early 90s. All the power adder's and making series power always led to some serious breakage, heartache and empty wallets. So many transmissions, holes in pistons, split blocks, the whole 9 yards. But it was a different time where we didn't have the technology they have now. Back in the day, we didn't have knock sensors with the aftermarket engine management systems and always had to tune very carefully. Something would always go wrong though….it was like chasing a pipe dream and an endless money pit.

Anyway….keep it going! Very impressive.

I’m sure you’ve said this- you’re in a LCI car? Just found a shop in Dallas that will bench unlock for $400. Thing I’m gonna make a trip over next week. JB4 is great, I will still use it for gauges. BM3 is the key to low 10s. What file you using on this recent run? I’m assuming you’re stage 2?

Ps- you need some ET Streets 😁

If you're running BM3, have you tried reducing the boost in lower gears?

Is that $400 total, or $400 per DME? If it's the total price, that's a great bargain indeed, especially if it includes removal and re-installation of both DMEs.

I repeated back $400 total? They said “yes, because you have 2”. We will see, want it done regardless.

This is the place https://www.cedar-performance.com. BM3 support are the ones that led me to them. They are the only ones even relatively close to where I am.

Don’t know how to post screenshots, multiple confirmed draggy runs 10.9@127-128mph

Straight moving!!!! Fuel used? Also, what does your timing curve look like. Total timing at 5500 and 5.1lbs. If you haven’t logged yet, I’d really be curious to see one.

[Antec800]

I have logs if you want me email you them I haven’t emailed Terry bunch of logs, I’m limited on going any higher then 5.5lbs Of boost added because of fuel, Terry said he’s working on ewg connectors and fuel pressure connectors for the newer cars, I think I’m averaging 17-18 timing

Pm sent! Ty!

[Boosted_8]

Which fuel are you using and why do you think the limit is 5 lbs when using it?

[Antec800]

Running out of fuel and running lean with to much e85 on more then 5-5.5 of added boost, race gas would work perfect for 7+ added boost but I don’t have any access to any esp for daily use. 93 would work fine on 6+ Psi but you lose a good amount of timing and the car isn’t quicker

How much E85 we’re you running?

I have a 2020 M550i RKtunes tune only car. My best was 10.8 @130
I attached the video. On stock RF tires, they were chirpin good amount.
Before I do downpipe stg2 map.
I wanted to see any LCI cars with downpipe e30 stg2 bm3. I feel like BM3 will get to mid 10s or even better. Before throwing meth and other stuff to it...

Good times but lci can't flash tune.
