Not sure how their implementation works, but they do have a clutch pressure sensor...

As for the over-revving, if on the stock DME, it works perfectly. I also datalog on the stock DME side, and can see it retarding timing during shifts. It also attempts to modulate throttle if it's unsucessful on the first try.

There's a lot in the TCU/ECU interaction going on during shifts..

I think I could learn a lot here Matt, more so than what I can offer lol. Will stay subscribed and keen to see your result.

I should have my updated V3 Xcal tonight, so I should have more to report soon as to what's gotten fixed and what has not.

Finally got the updated V3 xcal.

There were some minor issues with units (some things were converted internally, and although they seemed to be right when saved, were multiplied incorrectly...Fixed the values and all is well). Car seems to start up faster then with v2.

However, I seem to have lost CAN TPS.

No SMG stuff enabled either. Garth emailed Jason, and we're waiting to hear back from Jason tomorrow.

Sleep now.

Apparently the E46 v3_zz ('final') version is not ready yet. I was given the generic (no BMW CAN integration) version, which explains the issues I was having. Reverted back to v2 (yuck) for now.

The V2 firmware I have has no SMG support. Which explains the lack of being able to manage torque reduction.

It does not, however, explain why it never goes to OffIdle state.

As it turns out, an "xcal" file is nothing but a gzipped xml file. Makes for easy reading and modifications potentially. I did not, however, find anything else related to TPS that would explain why the CAN TPS stuff does not work right with the idle control. Grrr...

Not as of yet. It just means idle is terrible right now with the defroster (and therefore AC) on.

On another note, I dialed back the spark at > 100 kPa (ie boost) by 3 degrees. The values I was seeing in my DME log compared to the past were lower, so I took the more conservative number.

I turned on traction control after setting it to cut fuel, not spark.

I then proceeded to do a couple WOT pulls in traction compromised weather (1st and second gear, nothing crazy) , and it was fun. No drama, just kept going forward. Quite impressive.

Well, no v3 news yet. I did get in contact with the person who worked with bimmerguy055, and the firmware will get done, but no ETA available.

I also was able to compare the calibrations between bimmerguy055 and myself. There are a couple of items which stick out which could be the cause of why idle control works for him and not me.

* APP (Accelerator Pedal Position) has an analog input (though unused) assigned to it. Don't think this is it.
* Air Control Source is set to IAC for him, and ETC for me.
* Vehicle_Speed_Sensor_PResent is set to No for him, and Yes for me. I think this is the first thing to change. I have a feeling the idle control is not seeing MPH change and therefore detecting that I'm moving and no longer idle...

I'll report back when I get a chance to make these changes.

You do realize that even though your car has an ETC, idle is still controlled via an IAC motor, right?

Yes. Currently the DME is controlling idle and throttle anyway. I was looking for differences which may be messing with the ProEFI's idle logic.

Can ProEFI not take control of all engine functions? Forgive my ignorance but I don't understand why the stock DME is still being used to control idle etc. Can you control the Ethrottle?

Yes, it can. However, that will cause a check engine light, which I want to avoid. That was one of the motivations for going with ProEFI was a relatively clean integration.

OK got it. I run a Vipec and had to manually disable my EML and T/C light - I still pass inspection in my country OK.

I reccomend if possible moving the control of the electronic throttle to ProEFI, I noticed a huge increase in response.

Heh, I was going to ask where you were.

In the US, in NY, I don't think I'd be able to get away with that.

Highly, highly irritating.

GOOD NEWS EVERYBODY!

So, I have non-stupid idle control now.

It turns out, YES - Air Control Source is the important setting. I tried the VSS Present change first, and that just made it go to default of 5 MPH. Not sure how bimmerguy's working...

Put it back. Switched the air control source, moved a little, and OFFIDLE. Holy crap.

So now I have reasonable spark control in there of -10 to +5 as my limits, and idle is good. The -10 is there for if it starts to race a bit on it's own... It's enough range to pull it back down.

Decel fuel is still a no-go, but having an idle that didn't suck was very important to me.

Thinking more on this, I think the behavior is not surprising.

I told the unit that I was using the Electronic Throttle Control to control idle.

I have no Accelerator Pedal Position Sensors assigned. I have no TPS assigned aside from CAN.

Thus the unit had no idea when the "ETC" was actualy "off idle", which in this case, would not be, ever, as it's not being controlled.

I just wish I thought about that a bit harder a few weeks ago.

I have noted that the VR Crank + E46 CAN files are up on the ProEFI site. Hopefully I should have the _zz firmware for my car within a week or two at this rate.

I've worked on cranking fuel a bit, and depending on the coolant temp, it starts up much better now. Super cold (ie cold outside and first start) is still a bit longer then I'd like. I think I need a bit more fuel.

So I did some simultaneous logging with BMWLogger and ProEFI on "turbo" rate, and yes, my fueling #s were way off.

I was not injecting nearly as much fuel as the DME thought it should, which explained the long crank times.

I have come up with a new table, but due to the awesome weather outside (lightning a few minutes ago, now rain / snow), I will not be testing it tonight. Should be interesting.

Noteworthy is that the Gas cranking table does NOT have enough resolution for our engines. The Ethanol blend table is 12 bit, but the Gas is only 8. So max of 255 mg/cycle. For us, it's simply Injector PW * 6 = mg/cycle. So 255 is 42.5 milliseconds, but at 32 degrees ECT the DME was injecting 52 ms of fuel, which would be 312 mg/cycle, aka, too large for table. One can get around this by turning on the flex fuel cranking blend, but I have not tried that. When I did try it, it was with values that were not correct, and seemed to just make it worse.

At this rate, still looking at at least another week until v3.

IPW of 52ms? Are you sure your units are right? Normal cranking IPW are between 3 and 15ms.

Prime pulse can be that high but thats not cranking IPW. It was said that the 0rpm value was the prime pulse, but Jason as refuted that, so I dont know how you prime pulse.

Yep - other values, with warmer coolant temps, are in that range. (5-7 ms)

When cold, there is a lot of fuel injected.

Edit: Keep in mind I have 37# injectors.
