Some Tune Comparisons with VD and Logs

[csu87]

Posted these up on the other forums but figured I would post them up here. I will be adding to these with FBO on 91oct, FBO w/ Meth on 91, FBO on e85 and FBO w/ Meth on e85 once I find a good place to get some logging done. I moved since I did the originals and everywhere I go to log, I can get 1-2 runs in before police start camping out on the road. Also will be getting on a Dyno soon to get a new baseline and new actual Dynos to compare to VD.

So Ive been curious as to the differences between the MHD OTS Maps vs the JB4 + Backend Flashes, so I decided to do some testing.


Car: 2009 335xi
Mods: Intake, LPFP Stage 2, NGK Plugs
Stock FMIC, Stock DPs


Bought the MHD Stage 1 OTS Map v4 and the MHD e40 OTS Map v4 and used the latest BMS Pump and e85 flashes. Used 91oct for the stock, Stage 1 and Pump + JB4 M5. ~e40 blend for the e40 map and e85 + JB4 M7.


All runs were on the same road, started at the same spot and I tried to start at the same RPM for all of them.


For the Stock Log it was about 85 degrees ambient
For the 91 Logs, it was about 85 degrees ambient
For the e40 Logs, it was about 75 degrees ambient


Did my best to let the car cool down between runs and between Map Changes. For the 91 runs, I flashed MHD Stage 1, then did the BMS Pump after. For the e40 runs, I flashed BMS e85, then did MHD e40 after.


Review:
MHD Stage 1:Had some low throttle issues, but once I got on the gas, throttle was smooth. No complaints, however it is definately a Stage 1 tune in all sense of the word. Can tell a small difference in power vs stock, but would leave me wanting more if this was my tune. Max Boost 14psi 319whp/349wtq


BMS Pump + JB4 Map 5:None of the low throttle issues, and definitely had more power than the Stage 1. However, this combo was boosting to 16psi vs the 14psi of the Stage 1 so that is the difference in power. I chose the Map 5 vs Map 1 or 2 since that is the Map I have used since I bought the car. Max Boost 16psi 346whp/382wtq


MHD E40: Lots of POWA!!! No throttle issues with this map. Noticeable difference vs both 91 octane maps. Timing was fairly stable until the upper RPMs where Cyl 5 dropped timing a few degrees. Timing curve followed a different curve than I am used to however. Started high and slowly declined. Max boost ~18.5 392whp/425wtq


BMS e85 + JB4 Map7: Pretty much the same as the MHD e40 in driveability and feel. Timing followed the curve Im used to with my car, where it starts low and slowly builds. Max Boost - Just under 20psi. 385whp/449wtq


Overall, if you are running an e40 blend, either option isnt a bad choice. Not much difference in terms of power.


Below are some Virtual Dynos to show a comparison. I calibrated the VD by using a baseline I have of my car on a Dynojet where I put down 271whp. However the wtq number of 308 shown in VD is high by about 20. I put down 285wtq. So keep that in mind with the torque figures.


1st Graph has stock vs 91 vs e40 (All Maps)



2nd Graph has stock vs 91 maps



3rd Graph has Stock vs e40 maps



Last Graph is 91 maps vs e40 maps

Take this for what it is. I wish I was able to do all this on an actual dyno, but I didnt feel like paying several hundred to rent out a dyno. Ill add a 100% e85 log tomorrow. Ran out of daylight to do it. If someone has a Map for e60+, give it to me and ill compare it to e60 with jb4. Not really wanting to pay much for a map that Im not going to use. Already spent $80 on Maps.

Put in an e75-e80 blend. Not exactly sure how much e40 was left in the tank, and I didnt fill all the way up. Used the BMS e85 Flash and Map 7 again.


It has some more power than the BMS e85 + Map 7 runs, but not much more than the MHD e40 runs. However, with FBO, I feel that you will see a lot more power gains, as the turbos are basically working as hard as they can, but boost falls off rather quickly due to the restrictions in the stock system + high IATs in the upper RPM range. However, completely stock except for LPFP Stage 2 Kit, Chargepipe and Intake w/ NGK Plugs, it still made 20.5psi and 398whp/454wtq.


Here are the Dyno Graphs


All Maps (Sorry, had to reload VD and the dynos all swapped colors on me.)



All the BMS Backend Maps (Stock vs 91oct vs e40 vs e80)



e80 vs e40 maps



and the log from the run.

Also, if anyone is interested, I have all the CSV Files unfiltered and you can see 3rd to 4th shifts and recoveries and anything else you want to look at from the runs. Just PM me your email and I'll shoot them over.

I have a dynojet, and a newly acquired 2008 335i auto. I will be posting up my dyno results soon similar to what you have done here. From stock to FBO on e60.

Nice. Only dyno close to me that will work with my car is about 30 minutes away and they only have 1 guy that can operate the dyno that only works part time... I had to schedule 2 months out in advance lol.
