11.8@121mph on straight 98

[martymil]

So ive been doing a lot of tuning, logging, testing and I think its paid off

The jb4 platform has come a long way when stacked with Custom Trebila MHD Back end flash

That's an impressive time on pump fuel.
Your run makes all the 700hp single turbos with Pi and e85 look silly at the track.

What setup does it have?

[martymil]

Rb classics, inlets, down pipes, akra axel back, monster ic wirh a custom 3inch up pipe and custom 3 inch charge pipe with custom bov's, jb4 and mhd bef

And a number of fueling mods that dont add to power but help with fuel pressure

[Brule]

Ok I thought it was going to be your e90 you bought then I seen the photo and thought it was a new 135i setup.

I don't know how you got 11.8 in a manual.

And on normal tyres

[martymil]

The e92 is sitting collecting dust atm, lots of things going on behind the scenes and its put into the corner under a cover for now

[tawfeeqh]

Not bad for straight 98 and manual. Decent trap too

[martymil]

Now just waiting for the flex fuel setup from mhd to test out, fun times ahead.

I have the perfect e85 tune and 98 tune all I need to do is scale between both.

But none of this would have happened without the new ic from JDTuning aka jd75 the forum sponsor

Its so consistent and the iat suppression is unbelievable, it makes tuning easy as you dont have to wait
between runs to cool down and you can basically do run after run and not get any heatsoak

I do have a few prototype fuel mods which will be available soon which I'm testing to keep the pressure
up in the di rail.

i might be moving off topic here.. but how are you using the JB4 with the MHD flash? Like in what way?

I just got pure stage 2's, MHD bef with the new XHP transmission flash and had my JB4 removed.

Awesome run though getting into the 11's on pump, that is a goal for me.

[martymil]

You get JD75 or trebilla to write you a custom bef and stack it with jb4 and you can still use xhp

Lot of people think you have to go one or the other but not the case, jb4 has many safety features that mhd doesnt so a good marriage between the two is a win win

An unbelievable run on 20inch rims and 98RON in a manual 1M. No meth, no E85, no tricks and raced as you drive it in genuine street trim Well done!

Marty, you certainly are making some incremental and amazing improvements to N54 that will surely become standard fare across the platform.

How much power did this tune make on Advan's dyno?

[martymil]

351rwk

[totti84]

350rwkw is impressive on 98RON.. well done!

[martymil]

No fancy tricks, no meth, no additives, no e85 and no pi

Just straight di, stage 3 pump and a lpfp fuel line de-restriction

A lot of effort and fine tuning, testing and revisions of the flash went into it and a big
thanks to Trebila, jd75 and Advan for putting up with me.

I know I can be a pain in the ass sometimes but there is a method to my madness

The proof is in the pudding

[Alpha Trion]

Awesome work Marty!

[martymil]

Thanks guys but im not doing this for recognition just showing you what can be achived on this platform and how simply it can be done with the right parts

[Brule]

I'm not sure how you got that power on 7 degree adv and 20 psi.

The intercooler is the best for keeping cool but the turbos are working for it.

You have about 40kw more at the wheels than what others get with the same timing and boost.

I believe the power from the trap speeds.

Have you done anything else like up the hpfp tables?

Can you log wgdc bank 1 or 2 with jb4?
I can't remember if 50pwm is max or if it's low?


I'm jealous, annoyed, intrigued, interested how you got 11.8 on pump fuel and on 20's for god sake!

[martymil]

Trebila does all the work with the tune, he is a real gun when it comes to BEF

I don't think you can log the wgdc separately, I always believed the lower the pww the lower the restriction in the inlet system but its hard to measure how hard the turbos are working without physical equipment to measure shaft speed. PWM goes all the way to 70

I know the turbos aren't maxed because they make their peak power on e85 at 23psi and that's 421rwk

The IC is where I picked up my power.

I provided the results on the other website but so called turbo builder made fun of the findings, guess I had the last laugh.

I don't even bother with that idiot anymore, its more fun beating my head on a brick wall

I found another few incremental improvements in the fuel system which I'm working on but that's only to increase fuel pressure to allow more flexibility with tuning

Don't forget the nice wide guards the 1m has and I'm running super sticky contis which are 295 wide.

[Brule]

I'll go look at ur pwm data on the other place.

I need stable iat and less restriction

[martymil]

Just got confirmation from the terry the pwm is wgdc and the scale is 0 to 100 so the turbos aren't working hard at all or at least the waste gate isnt working the turbos hard

Terry renamed pwm to wgdc in the latest interface released today

Do you run a jb4 ? If you do run menu 6/1 to run max cool mode and run your car for at least 5 min before you stage up at the drags it will stabilize your water temp, oil temp and your iat's

This will get you more consistent, unless your ic is not up to it

[dh58]

Awesome! And on ron98, so no more e85 life and having to worry about where you're going lol.
