Updated logs (from post #2887).

https://datazap.me/u/johnscales/6040...og=0&data=3-23

Much better now. Found out that my w/meth calculation was way out. I thought I had a 1 gallon tank (imperial not US liquid gallon) which would have been 4.5 litres. Litres is the common unit of measure here in the UK hence the conversion. However my meth tank is actually 4 quarts/1 US liquid gallon or 3.7 litres (thanks google conversion calculator) so the 50/50 mix I assumed I was putting in was more like 60 - 70 water / 40 - 30 meth. I poured the water first and topped the tank up with the meth but will have been almost a litre of meth short. This evening I purged the tank and put the proper 50/50 mix.
Car was back to feeling silky again. I'd say 95% of the way pre meth install for normal driving. Definitely felt significantly more torque during my runs and the steering became eerily light as the revs built in 3rd.
Anyway, am happier now. I may tweak further (different ratios) as it's as fun as logging the drive. I think I'm getting the tuning bug.

Only issue I see is throttle closure (unfelt during the pull) due to overboosting slightly. Not sure if it's dialoutable (not even a word I know) or wether i'd bother trying but it happened on both runs tonight.

@Jerain. I'm nearly at 10 degrees of timing near the top of the pull now. Not that I 'get it' but I take it that's a good thing right
Timing pull is also almost eliminated.

Sorry didn't see that until after I posted.
I flashed their file and it went a whole lot worse.
Felt like misfires up top, was requesting more boost (20 psi) which just felt bad. Lots of timing corrections as well.
Flashed back to mhd and runs much better. I'll contact RFP and see if there's a better file for my car.
Here's a log with RFP stage 3. Didn't want to do more logs as it felt wrong.
Take a look at the timing correction.

Yeah, thats ugly.

Talk with him and see if anything else makes sense, but thats his only ots file for inlets. Probably time for something custom, 91 tunes typically need some dialing as the quality of that fuel varies so widely.

Do you have recent coils? Recent plugs? Walnut blasted?

I had to let off the throttle as I was approaching 100mph on an on ramp in to a highway with speed traps.

I logged a run today 3rd - 4th at full WOT with traction control off. Input from anyone is appreciated.

Coils and plugs last week. Gapped to 0.022". Walnut blast might have to be next.

New to mapping my car via a phone app and would greatly appreciate it if anyone would have a look at my logs, I think the timing corrections are too big but don't know much in all honesty.

Car is FBO +inlets, outlets and PR ignition kit. MHD Stage 2+ on OEM plugs with around 5,000 miles.

Thanks in advance.

Corrections aren't terrible given the mods and map.

The mhd maps are NOT made for inlets and outlets. You need a custom tune.

Hey guys, just got done working on the car and pulled a log. Mods are:

VRSF 7"HD
Catless DP
VTT charge pipe abd BOV
Silicone inlets
NGK 95770 gapped to .022
New coils 8k ago

Running MHD stage 2+ 93 oct. Looks like a few timing corrections. Let me know what you think. Thanks in advance!

Hi Please review and comment on my log:

https://datazap.me/u/doogguhbee/hesi...og=0&data=3-20

My main concern is hesitation and bogging under sudden load at low RPM. I'm seeing multiple cylinder corrections when this happens per the log if I'm understanding it correctly.

I believe this issue started after I got walnut blasted a number of years back - I'm suspecting that the intake manifold nipple going to the Diverter Valves or some type of vacuum related issue.

I don't have this issue at high rpm/high load/WOT.

Thanks in advance.

Thanks for the help, contacted him for a custom tune and it drives a lot better now. Less throttle closure and this is only revision 2 of the tune. He's sending me another one to smooth things out. Highly recommend RFP tuning.
Here's a 3rd gear pull

Thanks mate going to get in touch with Ken tonight and sort a custom tune. Think I'll do the injectors and plugs before hand as well.

I managed a 2-4 gear pull today and there are massive corrections on all cylinders bar 2 through the full pull.

https://datazap.me/u/mclean6366/2nd-4th-gear-pull?log=0&data=2-6-7-8-9-10-20

I'm more just trying to understand the logs, they seem to spike around the gear shifts, is that normal?

Cheers again.

2 Step colder plugs gapped to .025
Corrections are a little better but still under boosting.

Hello All,

so i have 09 335i, with MHD, VRSF CP, 5' FMIC, BMS DCI & OCC, so where do i go from here to add more power?

I would do down pipes next. Then Meth or Ethanol.

Have you reset any adaptations since winter blend was in the car?

I don't see it being a cure all but I am curious considering how well your car runs otherwise, this doesnt make much sense.

Time for a boost leak test afterwards if no improvement I guess.

what hardware i need for Meth or Ethanol and how much power i will be adding, im new to tuning

Thanks Drew, I have not reset them. I think they reset after a flash though which I have done half a dozen times this year. Maybe its time to get INPA out.
I have never done a leak test before but I am leaning in that direction.
Is that something you could help with? I can come to you? Buy you beer or whatever your fee is?

I don't run Meth do I won't comment on it but it looks pretty straight forward with some Googling. E85 you need to install an ethanol sensor, tap the ECU, and run a MHD Flex fuel map. Total is about $400 or $500 for everything.

Boost leak test is easy enough on most cars, never done it on this but cant be too bad. Basically need a tester to bolt onto one of the inlets, seal it and pressurize it to about 20lbs or whatever you normally see and see if the system holds it.

That said, normally we would want the throttle plate open for this and im sure how to do that with e throttle. But we can test half the system with it closed.

Just need an air compressor with a gauge and then a tester like this;

http://www.siliconeintakes.com/intak...ter-p-165.html

And not something I can do at my place unfortunately, no garage or compressor anymore but if you have a space and compressor I dont mind coming by and trying on a free day. But it would be learning experience for me too.

Guess to open the throttle we could just turn key on but no engine and open the throttle with pedal until test was complete. Idk just brain storming now.

Cool, thanks Drew. I'll think it over the next few days.

Also, I have reset adaptations almost right after a flash and noticed a difference. So I do think at least some hold learned values through the flash.

[alexristainoN54]

anyone else have issues with xhp then flashing a new mhd map? makes my transmission jerky and start in third. have to go back and do xhp first then flash mhd. annoying but fixable.
just curious is anyone else had this issue.
