The entire point of VD is to use it as a tool to compare your own logs after hardware or software changes, with only one variable changed at a time, under the closest atmospheric conditions you can possibly get, and on exactly the same road to eliminate elevation changes (upslope/downslope) that would affect acceleration results. It's also useful for comparing back to back logs on your car to see things like how much getting timing corrections can affect your (estimated) power. I think the first two posts in my VD thead specifically illustrate this point, and they clearly demonstate the benefits of hardware and software changes and based on all other data from actual dynos and manufacturer claims they are quite accurate. But again putting a bunch of different people's logs in VD to compare to your own or eachother means nothing. --> https://f30.bimmerpost.com/forums/sh....php?t=1710794 VD gets misused because people are obsessed with HP numbers for no reason at all. whether you are making xxx hp or xyy hp is irrelevant. All you need is a solid and reliable tune for your setup. The only place VD would play a role relevant to this thread is if someone were to flash the BM3 stage 2 E30 map, go log, then flash the stage 2+ E30 map with no other changes, give the car a little time to adapt, then go back to the same exact spot under as close of conditions as possible and get another log on the new map. Then, we could toss them in VD and see what it looks like, because its just another way to estimate the delta from the tune change (similar to acceleration time, just inferring from logs), short of having actual back to back dyno runs. But again, its the delta that matters (and the curve, of course), not the peak hq/tq numbers, along with how clean the log is. |

I totally agree with you and should of put a disclaimer this is for entertainment purposes only...lol... Now if we can only get the logs that would really tell it all... Last edited by FastF30; 10-22-2020 at 11:08 PM.. |

good point place not to far... single roller... I'll wait for the best possible day and we'll see if I can at least break 350whp...lol... thanks for the fun...

i decided to ignore the need for upgraded HPFP and ran this on a stock HPFP
tune: stage 2+ race gas (not the e30 tune) note: i do not recommend this, however, it was worth testing, so here we go: my setup: -m235i n55 ewg -high flow cat -upgraded intercooler -ngk plugs @ 1 step cooler, STOCK gap about .031 inch. -stock fuel system, except: -WMI at 50/50 (i forget the nozzle size i'm using, but it was adequate when i was previously running the stage 2 race gas tune) https://www.bootmod3.net/log?id=5f91...729b52119f16ca my notes: -the stock HPFP can hang with the help from the WMI. -stock turbo can sustain 20psi at least up to 6200 rpm -this tune has more aggressive timing as compared to stage 2 race gas. about +1.5 degrees. -my cylinder 1 timing has always lagged behind the rest. possibly an issue with wmi not getting to that cylinder as well as others. my nozzle is installed pretty close to the throttle body as i have a VRSF chargepipe and there is only 1 meth bung. i am considering getting a new chargepipe with 2 bungs for better distribution, or i could simply increase nozzle size. -i have 2 other logs and one of which i think i experienced misfire, so it might be time to close gap on the spark plugs all feedback welcome!

coils are at 60k miles. original. i have not heard of slowly degrading performance, so i have not replaced them. i read it's either good or bad. thoughts? plugs are fresh at 5k miles

Hahaha...
Stock HPFP, stock downpipe Stg 2+ E30 8AT E33 in tank Sorry for the dirty log, but multiple 3rd gear, partial 4th gear pulls in it. https://www.bootmod3.net/log?id=5f92...729b518ea8a79a Yes drops in HPFP psi, but maintains perfect AFR and runs like a top. Will upgrade HPFP shortly. Black Friday come on!! Also, going to try to full flash this as the hpfp target is 2800+ and should be 2450 and that should help it not to drop as much. Have other logs with E28-E30 and less HPFP psi drops, so will try E31 and see how it does. One thing is for sure: This tune loves as much E as you can throw at it. |

Yes, I know... this is exactly what people were asking for - trying to race gas 2+ map with WMI+pump gas and no upgraded HPFP. I would say that's more common/likely scenario than people running HPFP+race gas with no WMI, at least on the street. |

I'm not gonna mention VD but I cleaned up some logs and he's coming in what a typical meth should add in power.. 50whp+/-

So, how does it feel compared to the regular Stg 2 Race Gas?

I know the dangers of doing what I am doing and have been running the Stg 2H E30 map for about 2 years now and the Stg 2 E30 map for 3 years with no HPFP drops of significance, like 200psi. I use Costco 93 + E85 that is at least E80 through testing. I only use these two fuel sources and wouldn't even think of hammering it with any other fuels without extensive logging. The Costco 93 logged perfect timing on the Stg 2H 93 tune, so that it proof that it is of the highest quality. I also run top lube in using Penzoil Synthetic Blend TCW3 to add back some of what the E85 takes out and it also is stabilizing. So this is how I thought that with my strong HPFP and great quality fuel that this 2+ map would do pretty well. I do have at least 10 other long multi-pull logs on this 2+ map with 4th gear pulls and the HPFP psi drop is less than this log I just provided, as this one is E33 as mentioned. I'll dig up the other logs when out of work and will probably pull a nice clean 4th gear one too. Last edited by ctt300; 10-23-2020 at 02:44 PM.. |

Stg 2 race gas is the equivalent to the Stg 2 E30 map and I've ran that extensively. This feels about 40% more powerful, as it is about 50+ WHP and has much more torquey deliciousness. I've been running the Stg 2H E30 map and this is about 30% over that from the way it feels and produces about 35 WHP more and maybe 30 ft lbs more torque.
Just a very smooth and very powerful power band. Exceptional tune!!! |

I see your in the magical land of Florida (best times come from there)... remember if your automatic... sport+, shifter to the left for manual and DSC off (hold button until off)... it should not kick down a gear when you floor it.. also colder and lower the humidity the better... |

so do the m235 and m2 n55 variants have the same manifold setup?
I'm noticing that the 235s and the m2s are able to maintain boost higher. no way I'm hitting anything near 20 at even 6k unless its a freak random occurrence.
