TTFS Dcan cable does not work. 540i e39 SC.

Have you attempted to virginize your dme and start again? I'm sure if Frank had a simple fix he would have sorted you out by now - have faith, I'm sure he will come good.

The fact it wont let you write to the DME makes me think there is something that Frank could not have forseen blocking the process.

Yes, we did a lot manipulations but no success. The only that make me happy is the Frenk trying to solve my problems some how. Bad side is waiting for him :-(

[dovlet]

Few days ago sent to Frank email and asked about any news for me, he said that he sent me file about week ago. But, I did not receive it. Asked him sent me that file again, just forward but nothing except ignoring. I am Almost give up, only ignoring, 95% of my emails with no response.

Dear all,
Received full flash file from FRANK TTFS. Installed and tried. Afr is 12.5 when full load. At 6200rpm afr is 10.5 then after 6200rpm 12.5 up to 7000rpm. Also, car is not running fast. My previouse 3.8pulley with 330cc injectors runned better or at least the same.

Any advise gents?
Soon will share my race logic numbers.

My advice is to discuss this with Frank. No tune is going to be perfect right away, so Frank may have to take several attempts at dialing in the tune when he's working remotely like this. Do you have a method of capturing datalogs you can send him so he can work from actual data?

Yes, discussed, he sent tune file for 15psi. Now I am trying to make some video and logs. Today will send to him.

Gents,

He said that I need tial type BOV with right spring. Can you please advise? Which one is for me?

Ok, this sounds better. So he sent you the 15psi tune by mistake? Do you have the proper tune now? Glad to hear your obd flashing situation was resolved.

The QRJ is the version that has been used by those of us on this forum, however you could try other alternatives - dont use a BOV as you need to recirculate not vent due to the maf. The QRJ pink spring is 1.5psi and is for superchargers.

btw, do you have an auto or 6mt? EDIT: nevermind, I can see in your sig

[geargrinder]

Yeah if you've deleted the MAF and frank is tuning speed density or alpha then a BOV is fine. But otherwise - with MAF you need BPV - bypass or also sometimes called 'diverter' valve .

As Zep says the QRJ is what guys have used on these motors. You don't need something huge like a big turbo would, and that one packages well to fit in the engine bay nicely vs the huge show-off things. Find Zep's pix of his install, it's pretty nice.

[dovlet]

Thanks gents for reply,

So, currently did video with logs and sent to Frank. Hope receive soon my tuned file for 10psi.

Also, looking for 1.5psi spring in qrj bov. Only 20psi is available here in my country.

[dovlet]

Cannot find ZEPs instalation of QRJ valve on his posts. Appreciate if someone can share it.

[philly98540]

I have some install details for the qrj install in my upping the boost thread.

I just copied what mcgnms did and Philly's setup is much more pro than mine.

Supposdly the 710N diverter valve that comes with the VF kit is rated up to 10psi, so you could just try and reposition the inlet into the pre-compressor intake pipe.

I take it you have a TU motor? If so, it will be intersting to see how it pans out for you. Mcgnms limited his TU setup with 3.25 pulley to 6000rpm due to leaning out, and Redshift also had leaning out issues after 6000rpm iirc. My setup also leans out heavily after 6100rpm - not sure about GG.

I make just shy of 10psi at 6100rpm, so if Frank can get the fuel in then you shoudl be able to keep going to 6800rpm and see a bit more than 9-10psi, maybe 12psi? I hope he can do it as I need him to sort my tune out to 6500rpm.

You think it will work?

As soon as i get my car tuned i will let yoh know. Hope he will manage it.

Got it all sorted out?

Got it all sorted out?

Bro, just received and installed. All what i noted is my AC started work very well. Surprized little bit. But, i had chance to test it in ciry on bad asphalt with no grip. Within 1 may be 2 hour will be out of city on autoban. Hope i will note some power increase.

[dovlet]

Installed tuned file but result is not good at all. Have no filling that my power is increased in compare with my 3.8" puley and 330cc injectors.

[tptrsn]

Are your AFRs better?

[dovlet]

Are your AFRs better?

Specify you question please. If you meant afr now, it is about 12.5.

[dovlet]

Also, what do you think gents about next?
If i will test my car under 2 condition. First condition is intake air 15 degree celsiuse. Second condition is air intake temperature 30-35 degree celsiuse.

What will be final power or result in both condition? Car the same. If i had 400hp with air temperature 15 degree will i have about 400 or 390hp when air intake temperature is 30 degree?

[tptrsn]

Specify you question please. If you meant afr now, it is about 12.5.

I meant to ask if your AFRs are more consistently staying in the range you want it to be, throughout the RPM range. Especially the high RPM range where they seem to go lean.

[dovlet]

Gents, look at this.
Screenshot_20170609-230303.jpg
Gear is neutral. Gas full load. Boost is 0.68 bar or 10psi 6700rpm.
Screenshot_20170609-230341.jpg
3rd gear. Full load. 0.22bar or 3psi 6700rpm.

What is wrong with it?

[tptrsn]

Is that your wideband saying that you're at 15.9:1 AFR at 6700rpms in boost (albeit only a little bit of boost)?

[dovlet]

Yes, it is lean after 6100rpm. Also, what do you think about boost when full load? Why it is 10psi when I am full load with no gear in. And 3 psi max when i on any gear full load.?

[tptrsn]

Yes, it is lean after 6100rpm.

I'm not sure you're grasping just how lean 15.9 really is in boost. That's quite lean even when you're just cruising along with light throttle.

Also, what do you think about boost when full load? Why it is 10psi when I am full load with no gear in. And 3 psi max when i on any gear full load.?

I'm much more familiar with turbo setups, so I will leave that question to Philly98540 and Geargrinder who have a lot of first hand experience with setups like yours.

[Zep]

You need to get some logging done and post them up here (and to Frank obviously). What bypass/diverter a you running now? For what ever reason Frank has had trouble getting fuel in after 6100rpm on these TU motors, the non-VANOS motors dont seem to be a problem though.

EDIT: And now that you know its leaning out I would not run it past 6k until Frank can try and resolve. I might also get back in contact with Frank to see if we can resolve this leaning out issue.

Yes diverter. I think mine is open all time and that is why i have no power. Why am i think like that? Because when air goes through maf it is calculated by ecu. If i had leak some where else i had have reach afr. But, i have stable 12afr during full load. That means air is not beeded of from system. It is going back to recerculation system through diverter. Will try to change it tommorow.
