VF 620

Matheus · 11-12-2016, 10:41 AM

Hi there,
I'm pretty new in the forum. This is my first post but I always read almost everything to keep in touch with the news.
Well, I just bought a VF-620 SC kit, directly from VF-Engeneering. Everything went great with installation (my mechanic is really good) its impressive how the product quality is great.
Mike and Steve have been very responsive, and helped me with all the software flashes etc.
Everything was great until I started the car. It turned on, but died immediately after that. I tried again, and the same thing happened. So I thought that i maybe it could be something that I did wrong with the flashes. Re-flashed it. Once again the same problem happened.
In that point I was already very disappointed. I took the HEX Flash and putted on diagnoses mode, and an error appeared: 2B55 DCT. Anyone knows what is it?
My mechanic took place inside the car, and turned it on again. Same thing, dead right after. So him floored a little bit, for like 10 secs, and the car kept running, but several erros apeared in the screen, like engine fault, flat tire monitor, DBE error, DCT error etc.
Well, in that point we thought that it's probably something with the tune, but we are not sure.
Anyone already got through a similar situation?
I emailed VF but they are closed now. I'll wait until Monday to see if they can help me with it! .
Let me keep it clear here, I'm not telling that their product has problems, and I really think that VF is a great company, even because I choosed their product. I'm here just to know with someone already got through a issue like that.
Anyone can help me?
Thanks a lot guys

Sorry to hear. We have a good forum so some suggestions will flow in soon.

2B55 - It says DME : Air-Mass Sensor, Plausibility

Matheus · 11-14-2016, 06:39 AM

i Just took the fuel injectors out of the car and send a picture to VF. I hope that they can ensure me that those are he right ones.
This DME error, what could it be?
Maybe a tune error, or is there any chance that could be a installation mistake?

DME basicly Gas Type Engine module (Digital Motor Electronic). This is related Either Ecu update or something you guys did not install correctly on the Engine. Check out the Air Mass sensor. It causes the same symptoms when it fails. Let us know with the results!

Well, today I took a friend on mine who works in a locar BMW dealer (mechanic) to help me. We tried 2 things:
1- we flashed the stock software (BMW original) and kept the new fuel injectors, the came with the kit. The car started, but was easy to know that the mixture was too rich, due the bigger injectors. A huge gas smell came out the exhaust. No erros were found when changing the hex flash to diagnostic mode.

2- we changed the fuel injectors, putting back the OEM ones, with the BMW Stock software. The car started, without problems, running smoothly (for my surprise). No erros were found when putting the hex flash to diagnostic mode.

With that, we reached the conclusion that something was wrong with the software VF sent me.

I already emailed them and they are very helpful with me. I must thank Steve for his help. He told that they will re-check the files and give a feedback.

Thanks guys for help. I'll keep u in touch.

I don't know if someone is following this thread, but if so, I think I found what the problem was about.
VF checked the tune and they were not able to find anything wrong with it, even because this same tune is running on at numerous cars around the world.
Well, I found some new codes using the hex flash tool.
1- 2B0D: idle speed control valve sensor bank 1
2- motor emergency program activated
With that we reach the conclusion that something went wrong with installation process, maybe they forgot to plug a sensor, I don't know.
Maybe my idle valve control is gone, but I hope not, because the car was running great before the SC install.
By the end of the day I'll have some news.
Thanks you all for support.

Matheus · 11-16-2016, 02:15 PM

Guys, I'm back here to find if someone can help me.
Today o went to a shop to put my car in a dyno.
Well, I got really disappointed...350whp with a VF-620 SC. And I was thinking the car was great. Really bad dyno butt I must say

(
Well, I wonder why is this happening...
We took out the vacuum conector from the BOV to check if the vacuum was being created...and it was. Not so big but it was.
So we placed a lambda sensor in the exhaust to measure the air/gas ratio, and the results was that the mixture was extremely rich.
What could it be?
Bad installation again I bet...
Thanks

Mfanatik · 11-18-2016, 05:02 PM

How many KM have you driven with the new tune and new adaptions? The car takes a tank of gas roughly and you will see the true numbers. If you've driven at least a tank and are getting low numbers see below.

1)What grade fuel is in the car?
2) Is there cats in any position of the exhaust?
If none: Great
If 1 set of quality HFC: ok
If Yes, all stock: Big problem

3) Are you logging boost?
If yes: What is your max boost, and what is your idle vacuum? If you are not hitting boost, your problem is a boost leak. You'd need to smoke/fog test the system to know where its coming from.
If no: You need to get this information

4) I'd recommend having a relatively, or a brand new set of plugs in the vehicle at the time of installation of a SC kit.

Hope this helps you..

Thanks for the reply, and sorry about my English.
I did not drove a tank yet. To be honest, not even half tank.
I'm running with a 95 octane gas, with iPE catless exhaust.
We did not measured the max boost or vacuum, it only be possible by tomorrow maybe.
I changed all my spark plugs during installation, they are all brand new.
Is it possible that low power just because I did not ran a tank?
Thanks
