Hi Guys, good news:

************** ISSUE SOLVED *********************

We ended up pulling the rear axle speed sensors (ABS sensor) on both sides of the car. Instead of removing the sensor near...

Hi Bren,

I think your right. It's certainly not the dyno technician, he just never experienced this. Seems like the open diff somehow didn't put 50/50 power to the wheels and the car noticed a...

Forgot to mention:

During the run the obvious warning lights came on: ABS failure, flat tire monitor failure, airbag failure.

When driving home they all disappeared again.

Hi guys,


My tuner and i are clueless about the following problem trying to dyno my BONE STOCK 2007 European 335i E91 (Touring) with 6 speed MT. He has a Land and Sea Axle Hub dyno. He's been...

The partnr for the fuel kit there is: 16112283496, which is different than the...

Hi GoodToGo, Your question will hopefully be answered by a tuner. I've always naively assumed, like Itsbrokeagain just commented, that there are plenty of pumps that could be used instead of the...

Hi GoodToGo,

i do not know the max flow rate capacity. I do know that the faulty first generation HPFP can now be replaced with a new improved version which seems to eliminate all the HPFP issues...

Hi guys,

An update from my Siemens/VDO/Continental contact.

Here are the questions and his answers. I'll leave the interpretation up to you guys, but at least the only thing you can destroy is...

Hi sticky,

Yes, i'm in Holland. RON98 (SuperPlus) = 93-94 AKI indeed in the US. I guess by raising boost we eventually hit the target power, but of course i want to run the boost as low as...

Hi Eleventeen,
I don't care too much about the color of the car; i hope i find a nice low mileage engine.

bobS, seems like you have a similar setup, apart from the RB turbo's.... do you have any...

Hi guys,

I'll try write an email to the engineer again on monday. Hopefully he will reply with more details. I'll ask the following:

- When were the injectors hotter than 100C ?
- Were the...

hi xbox,

I'm not quite sure how the heat makes its way to the injectors, but i since it's direct injection and they go thru the cylinder wall, the combustion energy is partially transferred to the...

Hi guys,

I have been looking into buying an E91 335 car since last year. I'm currently driving an E46 325ti with an ESS supercharger stage 2 (so with intercooler). Although this is a fun car, the...

Hi Sticky,

I have his email and phone number. I haven't talked to him in a while, but i promised him that when i have my project car ready, i'll drive to Germany to give him a ride (i live in the...

I talked to the engineer of the fuel system of the N54 engine. He strongly advices against running E85 if you're going to run it it hot a lot. Above 100 Celsius, the internals of the Siemens...

Thanks guys ! I feel very lucky to have met the engineer and it's great he's still taking the time to explain some things.
If and when my car is ready, i'll pass by to let him feel the power he...

That's almost a correct sentence, obviously i meant, their hands are tied by law.... :obscene-drinkingdr:

Hi guys,

I've asked my contact as Continental what the two variables means in the OP. This is his answer:

The variables you found is for injector characterisation for low injection quantities...

Hi Vassillalov,

Perhaps you can create a thread with all german phrases/words and people can reply the translation. If you update the OP, then we can see what's still to be translated. I can ask...

Awesome guys !

Dzenno: i bet you they typed a comma rather than a decimal point (or vice versa).

Great guys, thanks for keeping the topic alive. I'll contact the Conti engineer again in a few weeks (end january or so). I'll also ping ESS to see what they have on the LPFP pump.

And thanks for...

Hi guys,

I'm not sure if i have any bearing as the OP on where this thread is going, but it seems like we're diverting a tiny bit off topic. If i have a say on this, let's keep the knowledge,...

:D

Hi Michael, Rob,

I have checked realoem as far as those drawings let you. It looked the same to me, then i called the local BMW dealership, he also felt that it probably fits.
Of course i'll...
