Default e40 Mix Boost Seems Low - 05-21-2019, 06:59 PM

FBO with stage 2 fuel it lpfp
Pump BEF

Only hitting around 15psi. Shouldn't this be higher? I'm estimating around e30-40 mix. I put in 4 gallons 93 and 5 gallons e85 with around 1/8th of a tank of gas already in there. The first 3 logs were the first 3 pulls after doing a reset back to map 5. Should I switch to map 2 instead or the e85 bef?

Did you measure ethanol content? Trims are oddly out of whack a bit.

Ave ign is high, hence the lower boost target

If your over e30-Ish lad the race flash imo

I haven't measured the ethanol content. I don't have a tester. I plan on getting the ethanol line kit with the sensor from you guys soon but until then I'm just winging it.

Do you think it's safe to run the race map? Also, could these issues be caused by carbon build up? I'm at 65k and never had a walnut blast done. I just think it's weird that I'm hitting 15psi what people normally get just on pump gas. Is there anything that you can recommend I check? Appreciate all the help.

Edit - Also what about coil packs? Could it be caused by failing coil packs? I've recently replaced with new spark plugs and have 6 eldor coil pack on the way which I will swap out tomorrow.

Edit 2 - Had the car go into map 4 again. Doing a 2nd to 3rd gear pull. Don't have a log but I suspect it's the same as what I posted in this thread last week.

I reflashed the car last night and checked the settings.

Don’t think carbon build up would cause the issues your having

We’d need to see a log of the safety thrown to get a decent idea of what direction to go / correct

Got some more logs for you, Dave. I've realized it only drops into map 4 when shifting when doing a 2nd to 3rd pull. If I do a pull just from 3rd it doesn't drop into map 4.

Here are the logs. 2 of them are the 2nd-3rd gear pulls that drops into map 4 and one is just a 3rd gear pull.

Trims near max, and You go lean / trigger the map 4 switch.

Isn't the odd that it only seems to do it when shifting hard between 2nd-3rd gear?

If the LPFP is a new stage 2, the HPFP looks good, new plugs, new coils. What else is left to do? Possible injector issue? I believe they're index 12 (2013 335is). Not really sure where to go from here.

How old are your o2s

Try an o2 reset

Sorry for my ignorance but I'm guessing doing an adaptation reset in jb4 (1,7 from the steering wheel) will reset the o2s? Or is there another process of doing that?

o2s are as old as the car. 2013 - 65k miles.

I did the adaptation reset, still dropping to map 4.

Again it happened. Lean but trims aren't maxed?

This seemed to only start happening once I put the fuel pump in and e85. I checked all the connections on the fuel pump and it's good and the pressure looks fine.

Edit - One thing I've noticed I've been getting a 2DED shadow code ever since the new pump. Could this be related? Is it possible the adaptation reset didn't work the jb4? Didn't seem to make any difference when I did it. Not sure if there's a better method to go about it.

So I think I might have really screwed up here. I went in with INPA and deleted all of the adaptation options in adaptation set 1 and 2. Now the JB4 is reading the AFR stuck at 14.6 and the car is acting weird. Do I need to drive it more? Kind of concerned that the JB4 isn't reading AFR readings now...

Edit - Well I took the negative off the battery for a minute and that solved my problem. JB4 is reading AFR's again and car is running almost back to normal. Still dropping to map 4 still. Seems to only do it when I shift gears though.

Ok, so I'm an idiot. I loaded the race flash and oh my what difference! I did 3 learning pulls and this is what I have. How's it look? Timing looks way better but trims are still maxed? Is that an issue?

if you are using MHD, i would use it for reseting adaptations


But if you want to use the JB4
Menu 1/7 is for reseting battery
Menu 1/4 is for reseting lambda, octane, afr, knock adaptations
Wheel Menu POST#3

I tried JB4 at first went to 1/7 (guess I did that wrong) and didn't see a difference so I went in with INPA and reset all adaptations. I can give it another go with MHD. Would I have to do the 3 learning pulls again if I reset adaptation? Also, do I need to be in map 0 to reset adaptation via MHD?

I think it automatically goes to map 0 when you plug in the obd cable but don’t quote me on that, if it doesn’t then just switch to map 0

Deleted adaptations with MHD and trims still maxed and going into map 4 when shifting gears at WOT. Also getting 29e1 and 29e0 fuel mixture codes now. Logs attached.

You still have a pretty large bank to bank variance on your AFR and AFR 2
Trims still max
Still throwing safety 2 lean.

Is there anything that you’d suggest for me to do to try and get this fixed? I was told the WGDC was too high and could be a possible boost leak. Also duty bias should be 50 and not 0?

Duty Bias default can be 50 or zero imo at this point- doesn't matter

I'd replace the appropriate sensor at this point

Thanks for all the help Dave, really appreciate it.

I have 93 back in the tank and went back to the pump flash for now. I'm going to take some logs this weekend in map1 or map2 to see if the trims are still maxed. Do you think this would be a good starting point?

My thought process is if the trims are good with 93 and pump flash than it's not a sensor issue and more on the tuning side? I was thinking I could have had more e85 in the tank that I thought and maybe needed to load the e85 bef? Just wanted to get your thoughts before I tried or is that a waste of time?

You should try adjusting your 'fuel open loop' value and do some pulls. check what value you currently have and report back.
