Hi Terry. I think many of us are curious if Kline going to happen at all? I understand that you are busy but an estimated eta would be much appreciated.

Just following up on this. Any update?

Again, I understand you must be very busy. Thank you in advance.

+1 would be a great tool!

Running ST mhd/bms 13.2 flash. What offset should I use? 132?

[Terry @ BMS]

Start that and evaluate from there.

Almost got it working the other day but hit another snag. KLINE cars are such a headache. We're slowly working on it though!

[dreyo27]

are you guys working on this with MHD?

[Terry @ BMS]

Has nothing to do with our back end flash maps.

[Terry @ BMS]

Good news, got the virtual flex fuel logic working for KLINE cars. We'll need a few people to help test it out. Once it's verified working we'll start working on some VFF algorithm improvements I've been cooking up.

For the firmware just email me and specify twin or single turbo.

Hi Terry,

That is great news! I would be happy to test out the new firmware. Not sure how to email you personally though - your PM is disabled.

Thank you!

Awesome news!

How does the virtual ethanol work ? I noticed it changes values when I change fuel bias on pi. Same gas in the tank.

[Terry @ BMS]

Only heard from one potential KLINE tester so far... Where are you guys?

Also note when updating firmware the DME has to reset for the new commands to take effect. So lock doors, wait 5 min, and restart, is the quickest way to reset it.

I would like to be a tester. Please email me the firmware at zachh805@yahoo.com.

Email me at terry@burgertuning.com if you want to help test.

So is the best way to start using the VFF field:
needs to be calibrated using a fuel with verified ethanol content (i.e. straight 93 pump) and adjust the offset up/down until it matches the advertised ethanol content of the gas? i.e. if the pump 93 oct gas states "up to 10% ethanol" on the pump, then should adjust until I see something in the 5-10 range on the VFF field.
Just want to make sure I'm not missing something.
I normally run ~60-70% e85 and a custom flash, so I'll have to flash back to stock/non-e85 tune, change the JB4 menu setting, run out the e85, fill up with 93 oct, run it for a few-several days to monitor and fine-tune the offset value.

At that point, once it looks like the ethanol reading offset is dialed in, can go back to higher ethanol mixes and cutom e85 map with confidence that readings are somewhat close to accurate - correct?

[BMWSwede]

Testing in progress.
Waiting for the value to stabilize as it's still climbing.

But seems to be working at least.
Running E85 flash and as soon the value settles I will fine tune the vff field.

But it takes a LOT of idling/waiting for the value to rise to the 40 % i have in tank.

Is there any way to speed up the proces?
Been idling for 10 min and only got 15 so far.

[Terry @ BMS]

We may need to tweak the algorithm for KLINE as a few minor changes were needed. I'd just drive around and do what you normally do and let it do its thing in the background.

Update for Kline;
Running e40
Race BEF
VSO set to 146
76 degrees ambient air temp

Sitting at idle - without A/C (seems to make a big difference) for calibration, seems to be accurate, fluctuates between 38-41% on the gauge

I'll update more as conditions change

When turning the A/C on full blast at idle the gauge shoots up a little more than 10% (gauge fluctuates between 52-55% with a/c on, all else equal)

Well that would be over 20% which seems to be quite a difference. Surprised the A/C would have anything to do with it.

I think you know what I meant - 10 percentage points higher on the gauge...

As Terry advised, it only learns at idle -> A/C increases idle. It isn't ideal but I can see how it may be related...

Don't think I heard any news of this issue with the non-Kline cars though. I'm sure Terry can chime in - maybe this was one of the changes that they already caught.
