If you're getting 20mpg mixed, the E85 tradeoff just doesn't seem worth it for a daily.

Sorry, I should have qualified my gas mileage statement before. If I drive somewhat normally on E30, with just city I get 21-22mpg. But I am usually hammering it, so it’s a bit worse. Highway, I’ve seen 30-31. What tune/map are you on?

Gas mileage is basically going to come down to driving habits when we are talking about basically the same car (with slightly varying mods). I noticed no change in gas mileage when going from stock --> IC+CP Stage 1 --> IC+CP+DP Stage 2+ 91. I have also seen 30-31 highway in all cases.

I take a picture of my iDrive fuel economy/mileage/etc screen every single time i get gas and reset between fillups. Mileage is within 0.1-0.2 MPG of calculating manually. I average around 18 if i am doing 100% traffic/city driving with pulls whenever i get the chance. I will average about 22-24 if i have any significant amount of highway miles on the tank. However, i rarely am driving on the highway without traffic (welcome to SoCal) and if i am, i am probably doing 100+ pulls because its the middle of the night.

Comments:

- v7.0 boost increase is significant over v6.3 (from 15.8 on v6.3 to 17.2 on v7.0)

- With that said I'm not sure why I'm seeing boost quickly ramp up to 19.2PSI (not a boost spike) and ramp down to 15.8PSI. I believe the boost target is changing through the RPM band but for whatever reason, it's not being reflected in the boost target value in the log.

- Timing on cylinder 1 looks good on v7.0 when compared to v6.3 but I need to re-log with all cylinder timing parameters being logged. I forgot to change the logging parameters from a time when I was trying to diagnose some hesitation which I thought could be misfiring related (turned out I just need to reset the throttle adaptations).

- The logged RPM value tops out at 5700 RPM even though I know I logged up to 6800 RPM. You can see my speed increased even after the RPM stops at 5700 RPM. I'll probably reach out to PTF of this as I've never had this problem when logging before.

- For the v7.0 log with WMI I had to avoid an obstacle so I didn't floor the throttle right away but I was still able to capture a pretty good log.

Stage 2 v7.0 93 octane with WMI

Stage 2 v6.3 93 octane
http://www.bootmod3.net/log?id=5d0cca0eae729b66bd2152d0

Overall the tune is very smooth and increased torque in the lower RPM band is noticeable. I'm looking forward to throwing in some E85 and flashing the E30 Stage 2 tune to see how that logs. Previously I've seen my timing advance got from the 6-8 range to 10-12 degrees which adds a nice punch.

Car is overboosting 2psi but is not protecting itself/correcting with throttle closure??? What is happening with the RPM signal? You are only logging timing on cyl1 and you have 3° high rpm retard on that... I would be worried about how much correction you have on the other ones! I "like" how aggressively timing is ramped up after retard though. This is done much slower on MHD.

Spent some time with an 435i on our dynojet to squeeze out some more power and torque.

Baseline was low on this particular car but increase in percentage was 🔥

Mods are Wagner intercooler and downpipe

Stage 2 93 octane V6.4: 26% HP / 38% TQ
Stage 2 93 octane V7.0: 29% HP / 48% TQ

Stage 2 E30 octane V6.4: 29% HP / 44% TQ
Stage 2 E30 octane V7.0: 33% HP / 56% TQ

Graphs attached are in HP/LBFT and PS/NM - all measurements are done at the wheels!

Version 7.0, January 03, 2020:
- Boost target changes
- Boost and load control
- Power increase

Since the release of version 7.0 a week ago I've read a few issues that it sounded like guys were going to work with tech support to sort out. So have those issues been sorted? Are there any known issues that still have not found a solution? What is the current version? It started at version 7.0. Are we at something like version 7.03 right now?

I'm trying to understand how safe and error free the new version is before flashing it on my car which is running very well right now on the previous version. Thanks!

Ive had 0 issues with 7.0

Yeah the over boosting is a concern and I've reached out to PTF and sent them logs to review for both stage 2 93 octane and E30 maps. The logging parameters were my fault. I forgot to turn on cylinders 2-6. The RPM signal was also my fault, I had accidentally set that to max out at 5700 RPM. Both issues have been corrected so the next logs should have all the parameters needed. The E30 logs do show timing on all cylinders. The throttle closures I'm seeing on the E30 map are probably caused by the HPFP crashing, possibly due to too much ethanol, but I've run similar mixes on the v6.4 maps with no issue. I think the added boost + too much ethanol is a bad combo for my HPFP. Lastly, I noticed STFT is higher then I would expect with WMI. On the v6.4 map, my STFT would drop down to around 0.86 to compensate for the added fuel when spraying but on this map it at or around 1. I'll reply back when I get some input from PTF. On a side note, for daily driving this map is awesome but there are defeintly some bugs to work out at WOT with high load.

Does BM3 log STFT different than MHD? In my MHD logs STFT appears to be an actual % of correction (positive or negative), whereas you are suggesting BM3 reports it as a whole number? Such that 0.86 would mean -14% correction?

[JaredG_F30]

Correct. Numbers under 1 the DME is reducing fuel, greater then 1 it's adding fuel and 1 is nominal.

One of the reasons I switched to MHD... I dont like when safety is relaxed no matter the premise and however low the risk. I want to see throttle closure when there is overboost - period! I suspect that the ignition timing has also been made more aggressive the way it is increasing after retard. Releasing a new revision based on, what appears to be, results from ONE car......ehmm yeah...

The rest all look the same.. i have a 6th gear from like 2500 to 5300 pull but ran into some traffic and couldn't finish the pull so its mostly useless. But the other multi gear pulls all look similiar. All e30ish runs

[JaredG_F30]

Your log shows HPFP crashing in each gear and your boost (pre-throttle) is significantly under target. Your timing looks great though.

Here is a log from a revised map Halim sent me last night. I've sent it to him and waiting on a map revision. Still seeing some over boosting and HPFP crash. The lastest log does show throttle closure when the HPFP crashes and WG duty cycle drops to dump boost. Hoping to have a new map to flash before lunch so I can log during my lunch break.

My boost has always been like that. BM3 has always said that it looks fine.

I didnt even notice the crash down low, I was just glancing at it and it looked fine up top where I usually see crashes.

Whats weird is I have a 6th gear log where its overboosting and then shutting throttle multiple times. Guess its help ticket time lol.

sweet I sent him my 91 acnstage2 log ( i dm you on facebook btw) and havent had a chance to mix e30 v7.0 yet. Looks like youll pilot that program before i can!

I'm very intrigued with BM3 do they have a rep on the forum that I can private message? I have some questions for them.

Yeah but youre better off contacting them directly as they dont really monitor the sites.. they dont have that kind of time or man power.

Ditto. I did that and they replied fairly quickly.
