Hello all,

My turn now.

I just blew my motor out last month, probaly a week part or bad injector connection, it's not clear yet. I had overboosted @24psi, i don't think tune was an issue. But, anyway, i replaced motor with an 80K miles "brand new" N54.

I would need a conservative tune to make sure i would not blew motor again. I am a bi afraid. Motor has been installed 2 weeks ago, i will change my oil next week, and after, i'll be ready to do some pulls.

I would like Trebila have a look on it, if it's possible.

My car and my mods are:
335XI 2008 N54
Pure Stage 2 DD turbos,
2" inlets,
CTS Intercooler, DCI,
CTS ChargeP with Forge Diverter Valves with yellow spring,
Magnaflow exausts and you know what,
RB PCV Valve, 3.5Bar T-Map sensor,
Recent JB4 + MHD backed-end flash Pump.
I'am running on 91 octane

My goal is just a save tune, not too agressive that will not be hard on the life of the motor while beeing a cool daily drive.

Thank you.

It is most likely your JB4 that is protecting your engine and tricking the map4 mode.

If you look on the JB¤ interface, you will be able to see what tricked the fault. Do you have the JB4 app?

Hi

Helix sent me directly the definitions for VCV, and how to adjust them, yes.

Default 11.61@127.1mph stock turbos Trebila E50 BEF - 09-04-2019, 08:49 AM

I managed to consistently trap 127-128mph in the 1/4 mile last Sunday. The first 3 runs were on Map 3 (23.5psi) but found the engine did't feel as smooth and the IAT across the finish line were 160 degrees. Causing a cylinder 6 misfire.

Thereafter I used Map 7 (19.5psi) and found the engine to run much smoother and the IAT was only 130 degrees at the finish line. The 1/4 mile trap speed was slightly higher too and much more consistent.

I'm going to visit a different track in a couple of weeks which will be fully prepped and should knock my 60ft time down quite considerably. Overall I'm loving the car and the Trebila E50 flash is excellent

I'm stoked.
I'll be doing a Trebila tune in the next few weeks/months.
THE BEAST got me hooked after showing me some logs and videos. Stunning results. (thanks!)

I'm just tuning up the car pre Trebila. (Index 12 Injectors (after much debate) plugs, boost leak testing, etc)

I'm guessing it'll be 33% of my auto happiness. (cost to happiness... no idea why every JB4 user doesn't do it, just based on other's results)
First 33 goes to JB4, second 33 goes to BMS WMI.
All the other mods will have to share the remaining 1%. Just give me boost and timing and I'm happy!

I didnt think it was possible to trap that high on stock turbos ! Congrats !
Any weight reduction ?
Says 335i, but what model ?

Thanks! Neither did I think it was possible until I fitted some some front skinnies and gained 3-4mph.

The weight reduction totals at 267lbs so the car now weighs 3260lbs. I weigh 176lbs so 3436lbs in race weight. It's an E92 335i

Did my Trebilla tune in 2016 for my 1M Coupe.

haha and car is still running strong and smooth. I do not really like the idea of going on the dyno, but here’s a 100-200 run on pump gas and 100% meth.




Great job done by David

I had David do an e50 tune when I had stock twins and it was the best thing I did to my car.

Now I'm having him tune my 6466 single turbo conversion. I was slightly worried I went too large in my turbo choice, and the "lag" would take the fun out of putting around town. Boy, was I wrong. David's tune makes it barely noticeable i don't have stock twins anymore. And his response emails have always been next day.

I couldn't be more happy, or impressed.

Talking Very Pleased - Today, 10:14 AM

** E93, 4090 lbs (plus fuel and me), no weight reduction **

THE BEAST put me in touch with David.
Bang for buck, this was the best expense.

I've been rockin' the Trebila tune for approx 1 month now.
The power comes in so intensely now at such a low RPM, targeting 24 PSI by 3000 RPM.


The Turbos are stock, and inlets, as is my exhaust, so there are barriers on my side to spooling and breathing.
That said, it feels like a monster.

Between my traction (getting cold here) and no ideal test zone, my ability to log has been restrictive to obtaining the best log data.

A standard 3rd gear pull is attached. I couldn't go to 7k in this one.
My best official launch so far is 4.50 seconds.
This stretch of asphalt often registers as -0.4~*, however here is -0.93%.
Same spot I pulled a 4.01 (0-60(1ft)), but it registered as invalid as it breached the -1%.

I'm convinced with warm tires and a smooth surface, I can get sub 4 sec as is.
If I switch at 5000 or 5500 RPM, followed by not accidentally letting off the gas at the end (like in the attached), it should make a difference.
(I have to hold my first gear boost at 10 PSI now, just to hold the road with 275r, while I used to leave it open)

THE BEAST is THE BENCHMARK for the E93.
One day boss... one day! It'll be Ethanol vs. Methanol!
