I don't think I'd want to go narrower than that, do you?

I'm just looking at F80 guys that run 0.018-0.020 on E85 tunes. Not a guarantee and like I said your timing doesn't look bad, just showing corrections for some reason.

Yesterday tried to run on 102ron map with 100ron fuel+octane booster. It was a little bit slower than on 98ron map. Can you see the my logs on 102ron and 98ron.

Looks great, must feel nice.

Here's a Virtual Dyno of your 4th gear runs

The 98RON map is a nice 4th gear pull with 100% accelerator from 2300 RPM.

The 102 RON run is a 2nd to 3rd gear log that is not useful as you seemed to have a lot of wheel spin and DSC intervention.

Go and do a 4th gear run for the 102RON map like the 98RON map and post it up, then we can see the real difference.

Real nahice. Feels smooth and strong.

I'm AWD, did you set up this virtual dyno with that factor, or RWD?

Used a 340i X drive profile, same gearing, just a bit more weight, 70 additional pounds, car weight of 3710 lbs then used a nominal 176 lbs for driver weight.

Looks like you've got about 460 whp and should be good for about 11.6@121mph

Looks like a strong 93 octane tune 19 - 20 PSI and AFR's on the lean side. How much ethanol are you running?

MHD Stage 2, 93 Octane. No clue really how to log just did some quick pulls after I did the flash. Any insight would be appreciated.

Thanks!
2 gal E85 (not sure winter ratio), 8 gal of 93 Shell.

The bits you've captured aren't great for reviewing, but everything looks OK. Getting some good timing, up to 15 degrees on that fuel.

You really need to have the car in Sport+ manual and at least 3rd gear, ideally 4th gear, steady at about 2300 RPM then go 100% accelerator through to about 6800 RPM.

Ok, cool, I will try to out tomorrow when I get a chance. Thanks.

Cheers mate, I appreciate the data!

[baldeagleman]

Just did another run right now. 4th gear.

https://datazap.me/u/dparadis21/mhd-...og=0&data=4-16

Will this work better? Also, how did you make those virtual dyno runs. I downloaded the program and It just gives me really weird results.

That's a better log to look at. When did you flash the tune and how many miles since flashing it?

The car is having some persistent timing corrections throughout the run, indicating not enough octane for the boost and timing in the map. Timing Delta for knock should be at 0 and by the end of the run is at -1, indicating some knock is occurring.

Can you get better fuel? What are you using?

The other unusual thing I noticed was your fuel rail pressure dropping quite a bit below target from 2400 RPM through to about 5500 RPM. Should stay at 2900 PSI on that map unless you're blending some ethanol, but then your timing should be a lot better.

The car got to 16 PSI at 2400 RPM, which is really early.

The Virtual Dyno should look like this if you save the data file correctly.

I am using Citgo 93 octane (I think contains 10% ethanol). I have had a drivetrain malfunction error a couple times in the last two months when I was running JB4 + MHD BEF. Today I swapped to just MHD stage 2 for 93oct/98 RON so I literally did this flash a few hours ago. I haven't ever done anything to my sparkplugs and I wonder if they were the culprit in the drivetrain malfunction.

Side note, the MHD stage 2 flash seems way faster than my JB4/MHD BEF setup. I reckon I mustve messed up somewhere along the process of setting that up. Is there anything else I should look at to fix these logs?

[OzBMR]

The CSV file data must look like this. I have custom heading for boost "PSI"

If you've only just flashed the car it may be just an adaptions issue. You can try resetting adaptions in the MHD Flasher>Codes>Reset Adaptions with the ignition on, car not started, same as when you flash the car. Alternatively, disconnect the battery for a while.

Do you have access to 93 that doesn't have ethanol?

93 octane that has 10% ethanol starts as poor quality gas that they add ethanol to to get the octane up. If you can, blend some high quality 93 with some E85 once the gas in your tank is gone, then re-test.

This is what I'm getting now. Wasn't able to get the AFR in the spreadsheet, not sure if that will make the difference. I am getting between 418-441 depending on if I put my tires as 225/40/18 or 245/40/18 so this one is 235/40/18 (I run staggered 225s and 245s so I put the average?).

Would running the car like this have any potential for damage? I had my JB4/MHD BEF for like 6 months and I never did any type of logging until now. I'm kind of worried since the car seems to have way more power and is way more responsive with just the MHD stage 2 and you're saying I'm getting rail pressure drops and some knock which makes me think the JB4/MHD BEF might have had more serious issues. I probably drove 3k-5k miles on the JB4/MHD BEF combo.

The rail pressure drop and bit of knock is probably because of the fuel you're using. The car is doing a good job of managing itself, don't worry, just get better fuel when you can.

In car editor, change the drag co-efficient to 0.34, this is what is in the specifications for the car.

Add driver/passenger weight(s) as this will influence the output.

Tire height should be as per the rear tires 24.08 inches, this works with the gear ratios.



In Virtual Dyno>File>Options go to the columns and profiles tab and make sure it looks like this and you'll get your AFR and Boost as well

With that deep drop in fuel pressure you can just lean out anytime when requested injection amount should go up. Leaning out would lead to immediate knock events occuring and cracking piston ringlands. (that's the worst scenario)

[baldeagleman]

Wow thanks for all the help guys. What should I do to "get better gas"? Is CITGO not high quality? I also have a sunoco near me if that is considered better. Do you think I should replace the spark plugs? Couldn't that be part of the cause of the knocking? I dont think they've been replaced for awhile.
