Question about target aggression levels (1-5):
Can someone explain what a level of 1 represents vs a level of 2 or a 3, etc.

It's just a suggestion. It's not necessary for CANclear to work. But it's a good idea to do if you want to purge your DME of all tuner code data (no mattery how unlikely) before taking it to the dealership. It's the next protective step beyond standard code clearing which really doesn't clear the codes if BMW AG is given a reason to take a closer look. If you don't want the slightly different exhaust note on a daily basis and still want the protection, just unplug the solenoid the day or two before you take it to the dealership. It really only needs an hour or so of driving to do it's thing.

Driven my car only one day in the last two weeks. Time to get home, load up and drive. But that won't be until later in the weekend.

Wicked update Shiv!

One question: You mention in the diagnostic invisibility thread at the top that there are "potentially warranty-voiding tuning codes that are stored in the DME (even after a code clear)", which we started reading about here in the forum the last few weeks.

For all of us who were running the non CANClear maps until today, and went in with cleared codes for service/warranty work, then these shadow codes would have been there and we've all been flagged then in their system potentially, it sounds like? So even if going forward CANClear will do its job, we've already been tagged in their system...

You'd know if you got flagged. You're safe

Does this autotune map adjust both boost and ign corr? or just ign corr for now?

As mentioned in the docs, it's ignition correction only at this time.

Wow - nice update. I used to think I enjoyed data logging and making adjustments, but autotune is the sh!t. Now I'm anxious for autotune to take over boost adjustments!

The one thing I noticed is that it does take a while to learn (pretty sure I read adaptation was slowed down for stability) I did 2 full 3rd gear pulls and 4 partial pulls and was still correcting IC downwards. Loaded up with default values and after those pulls the IC was at 50% and dropping on an otherwise stock car - looks like default is pretty conservative.

Nice job Shiv & Vishnu crew!


Also - on the CANclear... from my experience you'll want to plan ahead so you have enough time after you follow the CANclear insx and remove the procede to reset the OBD readiness monitors. There is a sequence posted to follow, but takes some driving. I would think not having the OBD monitors ready would raise some eyebrows as well.

That purge trick really makes so much sense to me.

From emails I exchanged with Duram at BT, he speculated that the DME stores a finite amount of data and then overwrites the older stuff with more recent history........

So if you keep sending benign codes, it should eventually displace any older lingering ones

Nice!

On another note, I am still on the april maps and have no clue as to how the autotuning adjusts the amount of ignition correction you initially dial in.

For example, I currently run 35% UT with IC set to 75%.

If I repeat these same values with autotuning, will it then reduce the amount of ignition correction downwards until it hits some knock retard? Say 25% IC if the conditions allow?

Duram is correct. Although I find it funny that Mike@n54 and Terry@BMS claim otherwise when they speak on his behalf

Yep! It's really as easy as that. You can even leave the IC value at the default value of 100%. The Procede will automatically zero-in on the ideal IC. And that will range from 0-100% based on conditions. Couldn't be easier

Cheers,

Hey Shiv, question on the Auto Tune...If I install the new maps and firmware and decide not to go WOT, but rather drive like a grandma for 1-2 days, will the Procede "autotune" to Grandma mode and make me slow or does it constantly adjust as I adjust my driving style?

If you drive like a grandma, it wont even activate autotuning mode. There needs to be a minimum required load and throttle angle. So learning wont even begin until you start driving hard. Until then, it will be running the starting IC% value as per the User Adjustable entry.

Good to hear! We can speed up or slow down both the Aggression update rate AND/OR the speed of the IC correction. But I think the settings we have so far seem to work quite well. A good compromise between stabilty and response.

Great Thank you Shiv I will try it tomorrow

Keep the great work man Procede as so much involved since I bought it last year and I am very pleased with the product!

Shiv on the nitrous control link you mention that the Procede has switch outputs but do not mention where they are located on the PnP harness.

In nitrous mode (future use 1=100%), the roadspeed output doubles as an intelligent window switch output. This provides the ground to the nitrous relay when the engine conditions are met. The power to the relay is supplied by either a switch or (in my case) a steering wheel mounted button. When both conditions are met, the relay kicks on and drives both the nitrous solenoid and the secondary meth solenoid. And that same 12v activation signal is also fed back into the mapswitch input (what the remote relay box used to plug into), forcing the Procede to use Map2 which is mapped for nitrous. Pretty neat stuff. I just haven't gotten around to writing a schematic yet. Been so busy with everything else. But it's on the top of my list when I get back from vacation in a week.
