An Update To My Vishnu/FFTEC VFF 700 Single Turbo With *New* ProcedeFlash

One thing that I have always felt was important is to continue to work to improve your product no matter how good it is. Vishnu/FFTEC informed me that they have made some improvements to the ProcedeFlash, so I sent them my DME this week to upgrade it. They turned the DME and got it back to me within one day to minimize the impact. Today, I finally got to drive the car with the new firmware and ProcedeFlash, so I thought this was a good time for an update.


I always log updates first thing so I know what is going on with my car. As I see it, making sure the car is happy is critical. Let me jump right in and show you those logs... note in log 1 I ran the car at 21 psi to test things and in log 2 I pushed the boost back to 23 psi. MAP2 is boost as read from my AEM 3.5 bar sensor.








When I got done with the logs, the first thing I noticed was Vishnu/FFTEC clearly made some adjustments with fueling because my trims are now around 9% max at redline. I am amazed, but this fuel system definitely has a lot left in it! Shiv really has massaged this fuel system and has everything dialed in for a lot of power.


You will also notice a very refined boost control that is very, very smooth from peak boost to redline. Shiv has the boost control dialed in incredibly at this point. The car hits the commanded targets and stays spot on. It feels like Shiv has suceeded in making more power in the mid levels on the car. Prior to the update, it felt more like the boost ramped up a bit toward redline, but now it is a table top.


From a driveability standpoint, I wish I knew exactly what they are doing with the Procede / Flash to explain, but the car feels a bit snappier into boost now. It feels like my car builds boost a little quicker. It is just a bit quicker responding car than before and I felt before it was incredible how quick the car responded to my input.


The truth of the matter is Vishnu/FFTEC had my car dialed in incredibly well before the update, but it feels even a bit more bullish now. The mid rpm is the most noticeable area where the power has increased. The boost control is amazing with the new update too! I think this should put to rest whether our fuel system is maxed at this power level because the trims prove there is a lot left in this fuel system. I am interested to see the fuel system upgrade the Vishnu is planning to release and I will upgrade as soon as possible.

Nice. With that timing curve and 23 lbs of boost on the 62mm, that thing has to be pulling like a beast.

Since my car was really the first, we kind of knew there would need to be updates. I paid for shipping both ways.

Nope. You have all the updates already. This only really applies to FBIS since he did the single turbo conversion a while back

meth flow at 70! thats a pretty good amount of meth. According to Shiv's "datalog channels v5.2" doc 30% equates to 900 cc/min and 40% equates to 1200cc/min so does that mean that 70% equates to 2100 cc/min?? Another interesting bit is what looks like a timing event before you let off at the 6.9 sec mark. Is that anything to be concerned about? It would be good to see you IATs, can you post up your CSV file? I would like to check it out in virtual dyno also just for fun

setup looks sick, definitely seems like you can run more boost with the extra fuel headroom. why not dial up the boost more?

Impressive! Tip of the hat to Shiv, OP, and this forum for pushing the limit on the N54. The single turbo kit is a game changer.

What's the max fuel trim allowed at WOT? 100%? How does this calculation work?

Max trim would read at 34%, that's where fueling cuts out.

About 34%. This means there is a lot of head room still. Hopefully we can test that head room with MS109 since it isn't the fuel hog that E85 is.

I'll take mine at least once when it's done, but if I get into 10s I think they'll kick me without a cage.

I think it's if you break 135mph, although I'm not sure. Either way you'll have a good chance of getting kicked.

Well they won't know the first time

"Uh I ran a 12.8 last time...I have a helmet..."

Pretty soon they will start denying local 335i's
