What did you do to "clear your adaptations" that made your car feel stronger?

As for wiggle room with the boost percentage.
I would say you are close to being as high as you want to go.
If you are peaking at 14.6 psi (when accelerating, not a brief little common boost spike when you lift off the throttle) you are near the 15 psi limit.
You could raise the percentage to like 94.7xxx% and see what it does.

But keep in mind, you are in the nice cold winter months right now.
When summer comes you might be pushing the limits too much then.

I'm seeing peak boost of 14.4 psi occasionally and that's usually for a tiny little bit (like 100 rpms).
Most of the time the peak is at 14.2 psi.

I'm running 91 Octane though, and so that's enough for me in the cold weather, figuring in the heat of summer, I don't want any CEL's or codes from heat/boost related issues.

Since you are on 93 Octane, I'd say 14.6 psi peak is on the safe side and again, try 94.7 or 94.8% and see if you peak at 14.8 psi.
If so, and you are like me and want to be a smidge conservative and safe, I'd leave that as your limit.

Don't worry, come spring or even summer, I will do more datalogging and adjust accordingly. Also, we have only had about 6 days of cold weather here. The logs were all done around 80 degrees F. I assume during the summers of 90 - 95 degrees, I will cut back 1 or 2 percent.

The adaptation clearing has to be done by a BMW dealer. Usually they do it for a bad tank of gas causing a CEL, or bad gas causing eradict behavior, etc. It literally wipes the memory of the car. Say you get a tank of 91, but the computer sees it is really 87 or 89. The car adapts to that and cuts back power. Aso, the engine now thinks it rolled off the factory floor with the v2 or w/e performance mod you have on at the time, and will show a better response and increasein powe on the butt dyno .

15 psi is reportedly the highest you can safely (according to Shiv) go on pump gas.
You may be limited from your intake too.
Without enough air coming in you may never see any higher than 14.7 psi.

But don't be too eager for the quest of 15 psi.
The difference in power between 14.7 psi and 15 psi will be about 3-4 rwhp.
1 psi boost increase seems to equate to about 10-15 rwhp increase.

When I initially installed my v2 and then first dynoed it, the difference in power between the default 90.1xxx% settings and 92.1xxx% was like 9 rwhp. I think the datalog boost gauge showed a difference of 13.8 psi peak and 14.1-14.2 psi peak going from default to 92.1xxx%

Good thing I am going to be knocking out that air restriction soon!

BTW they clear your adaptations through the OBDII port. They either hook up a specific tool that can read codes and adaptations and clears them all, or they do it via laptop. If you want your own, I saw one on ebay for ~$3500.

That's interesting, I wonder if it's a placebo effect however.
Since the ECU will adapt up or down based on mods added, I wonder if "clearing" it really does anything other than start learning from new.

When you had this done at the dealer did they upload the newest version of the software, v27.xx.xx or whatever it's called that's now in the 2008 cars that some 2007 owners reported felt like they neutered the car after having this done?

And did you have this done with v2 IN the car?

I thought just unplugging the battery for at least an hour or two clears that all up anyway. Who knows, but thanks for clearing that up for me.

Nope, unplugging your battery won't do this for you. The DME stores it similar to a PC when it is unplugged. All your stuff is still there. I had all of my engine adaptations cleared. Nothing with transmission or thottle. Not a placebo effect, I promise.

BTW, the 2008 I put in the thread was meant to denote my car is an 08 model, 09/07 build. I have the 27 version of software. My stock dyno was ~281 - 284whp if I remember correctly, and my v1.47 was ~324 - 326whp. I had this done with the v2 still in the car.

Did you tell the dealer you had a PROcede, or did you just not let them drive the car?
What was the reasoning you told them you needed to have your adaptations cleared?
Do you have to drop off your car or do they do it right there on the spot for you?

I am on good terms with a SA at my dealership. I didn't sign any paperwork or anything, just saw him stick my keyfob into a keyfob reader after the work was done. It took me an hour b/c the dealer I go to is high-volume and very busy all the time. My SA drove the car back and made sure everything was handled correctly and returned with the car 1 hr later.

Normally, if you don't have such an acquaintence, I would recommend removing everything out of the car and taking it in saying you think you got a bad tank of gas and the car has adapted to it, etc. Play dumb but not too dumb and try and show you want your adaptations cleared. Say the car isn't performing like it should or w/e like that. Unless you know someone "straight" with modiications, etc. I personally can be upfront with my SA and he is completely understanding. Note that this is not the case for about 90% of the people coming in for service. I would try asking around for a cool SA from fellow BMW owners in your area, etc., that is how I found this SA. They are diamond in the ruff, but are there to be found.

Cool.
yeah I figured you'd have to have a hook up to do that, otherwise you'd be crazy to bring your car into a BMW dealer with the PROcede hooked up.

There is one cool BMW Tech around here too.
But to be honest, I'd still be nervous about bringing the car in with the PROcede, just in case.

But we'll see.
If I can have my adaptations cleared by him with the assurance he doesn't give a rat's ass that the PROcede is in there and won't do a work order at the dealer for it, then I'll maybe give it a try.

Later.

Good luck! I am sure you will be able to get it done.
