Procede 7-29 Auto-Tuning Logic
setup:
late '07 build e90 dci's fmic procede rev. III Last week, I was experiencing misfires that I thought were spark plugs, coil packs, or injectors (this thread). I inspected the plugs, they looked brand new still, and swapped coil packs. misfires continued. I did notice that the procede was autotuned to almost 0% ignition correction and 16psi of boost. as the misfires continued, autotuning ramped down ignition correction to 30%, then 60% and lowered boost. I decided to reset adaptations and see what happened. misfires stopped, and autotuning set more conservative ignition advance and boost values. I'm pretty sure I just had a bad tank of fuel, that was causing misfires due to the aggressive ignition advance and boost settings. new tank of gas this week; the procede has autotuned back to 0% ignition advance and 16psi of boost. my car only has dci's and an fmic. Is this too aggressive? should the procede react faster to a bad tank of fuel, instead of 3-4 limp mode incidents from misfires? I had fbo's on my old 135i, and I don't remember the v4 autotuning logic being this agressive. thanks in advance, bryce |

Try to run aggression level 1. This new autotuning is quite aggressive at 2 (default) and Shiv i think is working on it.
Without dps i would lower max boost to 15 psi.

iirc default boost settings were 13.5 in 1 and 14.5 on 2? if you are missfiring that is the first thing you need to adjust..... like enrita said 15 is the MAX i would run if i were you and even that to me isnt i consider conservative
people dont realise that you cant just crank up boost without compesating with things like higher onctane, timing etc.... tuning alone wont do it. the default settings are recommended for a reason and if you dont have the correct things to compensate for higher boost(higher octane/meth/etc.) then you are definitely going to get missfires |

sorry i gotcha.... in that case i would just turn down your max boost like already mentioned and see if it helps. i know where i live we have crappy gas anyway so i HAVE to keep my ign. correction higher and boost lower. i cant wait to get my PWM kit because it will help alot of my local fuel issues, although i still wont make as much as some can because i'll still have to run everything pretty conservatively.
edit. hopefully someday someone will have a full fuel system upgrade for these cars! they COULD make rediculous safe power all day long if we could just support E85! and imagine stacking meth on top of that!! |

that doesnt seem right..if its map 1 default 13.5, it will only autotune up to 15.5 since he has a 2psi threshold set

i'm not sure that 2psi threshold is true any longer for the new autotuning logic. it's definitely autotuned to the max boost setting (16psi) |

my 07 with intake on 93oct autotuned boost to 15 and IC to ~45. Last week the IC went down to ~35 but came back up.

Hmmm... I have read repeatedly that the maximum adjustment range for autotuning is a 2.0 PSI reduction, but I don't know if the same applies to boost increases. (It would seem to me that this is what the Max Boost parameter is for, but I'm only just starting to learn about all of the user parameters.)
Anyway, if you live in an area where gasoline quality is unpredictable or cost prohibitive, I can highly recommend the PWM methanol kit since you are already a Procede user. It is VERY effective. I live in Los Angeles which is home to some of the worst gas in the country, and some of the hottest temperatures, too. I fitted the PWM kit a few weeks ago and above all, it made my car consistent. With max boost at 16.5 and IC at 0, I have no timing drops, knock, misses, or muted throttle response, regardless of throttle position. I hit max boost with the hammer down, just like clockwork. (I'm using Boost Juice 50/50 at the moment. I'm going to pick up a five gallon pail of VP M1 shortly since that's available locally, and I've only been consuming about a gallon of 50/50 every three weeks or so.) To me, in turbocharged applications, a good methanol system and a tune that integrates it properly is just good sense in the US, where our EPA precludes consistent fuel. -Michael

The autotuning seems to be very aggresive and for us thats running only tune+dci its not useable, got recommended to turn it off and wait for next release.
After all its a beta.. Hopefully official release is coming out soon |

I have almost the same mods as OP:
07 e90 MT Procede 7/29 maps Helix IC Mr.5 Intake 93 octane I am having no problems at all at 16 psi boost and 0% IC. Autotuning will take boost higher but I have Max boost set at 16 psi. until I install DPs. Anyways, my point is it sounds like there is definately something else going on with the OPs car such as gas quality. I would not assume that the Procede is Autotuning too aggressive for his MODS. |

well i use old maps 12-17 and my car autotunes to 16 psi with mods below, start ign 50 and ut 40, http://www.e90post.com/forums/attach...1&d=1309079147 when i wot with second gear my fuel gauge jumps to 18 psi. maybe cos map 2 selected 45 ut should it be 40 as well? soon install ar dps and oil cooler hope to make ut 45 then
p.s http://www.e90post.com/forums/attach...1&d=1309079147 sorry for ot but does map 1 and map 2 should have equal ut or it doesnt matter as i have enthuasiastic version and i have map 0 and map 1 only
