And another 10-15 runs (not logged) this morning with same results. I sent the map to Ilma to confirm the results on his car. He's always been a great beta tester

To confirm, this is with CPS offsetting shut off?

I'd guess that CPS is on in those logs.

No, CPS offsetting is active. Not sure how this would have been resolved without it.

Shiv so what feedback did u get from ilma?

I'm pretty sure he has a day job so let's give him some time. When I have something to post up, I'll update this thread.

[Joshboody]

it's either more and/or longer retard during the shift probably. Longer retard may help MT timing post shift also. Can we experiment with this sometime?

IIRC, the Procede's bogfix works in that it offsets 3 degrees of ignition during the shift event. The problem is this bogfix won't engage if you don't lift off throttle.

I would believe once FFS and 2-step come out, bogfix will become obsolete.

Hi guys.

Sorry to be absent for so long, but I am in the middle of moving and have limited access to internet right now. Oh, and there is that damn day job too!

It keeps interfering with my car.

I ran a few logs earlier today and just sent them off to Shiv for analysis.

After reading shiv's comments about how the problem needs active ignition correction I am slapping my head because I ran quite a few of them with zero ignition correction as that is what I have been running all along.

Thought that would be more directly comparable......doh!

In any case, please bear with me. I ran out of my race gas blend and it was midnight so I will fill up tomorrow and run some more logs for Shiv to analyze with me using the proper settings this time.

But I gotta say, using high octane and low boost with zero ignition correction rocks.

It was in the 90's here today and the part throttle response felt amazingly good considering the ambients. And this is with no meth!

I promised Shiv I would not post results until he has seen them first, so please respect that he is working with me to try and get to the bottom of this issue. I give him a lot of credit and gratitude for doing so.

CPS is active even with ignition correction at 0%. In my logs I overlaid dme ignition against actual ignition with 0% ic

Oh...good!

That explains why things seem to be moving in a positive direction on my logs

Got a revised map from Shiv this morning.

Going out soon to get more race gas and do some more logs.

The guy at Pro Racing fuel always talks my ears off for half an hour.

That's reason enough to buy a meth kit right there!

Soon? Go out now!

Aha! So you're the guy he always keep mentioning to me lol the guy with yellow beard? Lol I love how he smokes 5 packs a day right near all that race gas lol

Hope you solve that issue soon and don't end up wasting too much money on race gas researching this issue...what happened with the pwm solution?

[themyst]

[themyst]

Question for Shiv:

I am guessing you are using DIC (dynamic ignition correction) to aim for the max set point post-shift... Will this fix if it works require us to run 100% IC regardless of boost for the fix to work? I don't care really as long as it's fixed, just curious.

Yes....actually there are two guys and they both have beards. Chuck and Mitch.

Chuck is the guy I usually talk with, and yes, he mentioned that there was another BMW guy who came in....was that you?

Shiv is trying to fix the map on stock settings first and I think it has something to do with ignition.

Start with one thing at a time.

But yep.....so far the problem is partially licked. I am getting about 3-4 degrees timing post shift consistently going into 4th gear. I think I will get meth regardless though.

[themyst]

So both the original fix and the "revised" maps are doing the same thing?

[themyst]

Bump for an update

[Ilma]

No updates.......

Shiv is MIA, and I am in the middle of moving so it's been tough for us to coordinate.

I sent him a set of logs, but he couldn't open them, so I resent them. Between moving and having sporadic internet availabilty we kind of lost touch. There is still no 100% solution to the timing drop.

There is an improvement in that it only drops to 3-4 degrees and then climbs, but it's still not like before the DME reflash.

Oddly, idk what BMS did but more people are reporting improved timing over there from a firmware update. I tried it once, timing flatlined and i didnt try again. Hmm...

Either way, looks like shivs making progress. I'd beta test for all of us pps meth kit users for him.

[OpenFlash]

Getting timing to no flatline post shift 6AT was easily. Now timing is in the 4-5deg range, ramping up from there. Which is would actually translate to an aggressive target of 1-1.5 which is spot-on for pump gas applications. Having more advance is also going to be easy. Just working out the logic for it now. Having it all wrap together with the current ignition timing logic will take some additional thought/testing.
