1.1.44 alpha released

[GintsK]

Does anyone have problems on 1.1.44 with tacho, fuel pump and other things driven from P259 chip?

Looks I have :-\

No, so far tested on 6cars.

BTW i'm driving on 1.1.5x for more than 2 months and using vemstune without problems.

Like tach cyclic jumps from zero point during non running engine?
Or misc outputs do not work as wanted?

VEMStune doesn't like my laptop, so I had to manufacture a Megatune version of the said loaded gun to shoot myself in the foot...

Needless to say it didn't work properly - I couldn't get the laptop to talk to the car reliably, so I reverted to 1.1.44

Hi,
I've noticed PW in MT jumps from 13 to zero repeatedly for a few seconds and then stops.
This is with engine not running. ???
Couldn't see any changes in the log that I did other than the PW changing...
Cheers,
Gavin :)

hi just going through this ready for the weekend,
why is there so many download and upload comands?
confussing or what.
download-config-9600 or download-config-19200
generate-config-12x12 and generate-config-12x12 with defaults
upload-config-9600 or upload-config-19200
upload-firmware-12x12 or upload-firmware-boot-12x12
firmware-uploader

what ones do i need to use please :-(

[dnb]

You need "upload-firmware-12x12" to put the firmware on.  (You may need "upload-firmware-boot-12x12" if things go wrong, but don't worry about that until it happens)

There's no real point in backing up your config because you should have that on the laptop and it's going to be like a new car anyway.   :)

ok mate ta

Are you clear on your wideband calibration (nernst dc and pump pw) values?

[Tony C]

nope lol,
i was going to look at the values in my current msq,
i did this last time we upgraded,
as double checked the ijector settings etc,
is there something i need to know then regarding the wideband etc Rob?

I've been dealing with some issue ever since I got my car running and driving.  Whenever it is cold out, I cannot for the life of me get the injector pulse width at idle to be reasonable for the first 20 seconds until EGO kicks on. 

I think the PW should be about 2.2 at 17 degree IAT and CLT (Celcius) but it jumps to and stays at 3.5-4ms until EGO kicks in, causing rich miss-fires.  I have gone through every menu on MT many times trying to get this to stop, or at least adjust it.  Today, I fiddled with multiple settings and now the car is too rich to start.  Any advice?

This is 1.1.44alpha on a 4age 20V using Alpha-N.

Warmup enrichment, afterstart?

Use the logs and megalogviewer to find the XXXe values .
Then you can which part is causing the effects.

[MWfire]

what are injectors settings(open time...)?

[Grant]

Sorry, I was away from my car and laptop this weekend.  I'll post up the settings.  They don't seem right though, as injector opening time is 0 at 13.2V or w/e the setting is, and the ramp up rate is a large (4 digit) number.

Gunni, I got a map from Jap-Kadett that you supposedly did for his 20V.  I can't see all of the data as I never found out what firmware he was reading.  1.44alpha doesn't show all of the information.

Can I assume the injector sequencing is correct?  I'm not sure what phasing I should have the injectors right now.  I think I will update my thread in the projects section later tonight with a few pictures and issues I'm having (mainly fuel economy around town).

BTW guys, the inability to actually start was from the car going from pig rich right after cranking (but still would run, just with rich miss-fires) to dieing right after cold start b/c of TOO LEAN!  I didn't realize I went from pig rich to too lean.  So today I messed with the warm up enrichment and I at least got the engine to maintain idle after a luke-warm start.  I'll see how it goes tomorrow morning.

I posted a few of my screen shots on my project page:

I'm unsure of the injector sequencing or the injector opening times.  Also, accel enrichment seems to be on full time, no matter how slow I open the throttle.
