Problem uploading VEMS firmware

Excellent

always keep a paper clip handy for the reset procedure. i always have a couple hanging about.

I'm a little late to this thread, but most of the replies on here are accurate: vemstune seems to work much better on firmware revisions over 1.1.6x. While it is technically compatible with 1.1.27, sometimes rolling back to that firmware is more difficult with vemstune than with the .bat file and the 'loopback' trick with the paperclip.

Just a couple of quick questions:

What is the difference between the firmware 1.1.27 if you use Vemstune and select Audi 12x12 or if I use the firmware upload bat from efiexpress? I tried to use the method Jamo described earlier in the thread but VemsTune list the firmware as 1.1.23?

When I did the firmware upload I selected in Vemstune I selected 12x12 audi from the 1.1.27 folder and the I choose to add "air patch PTC 425 260" and "coolant patch NTC 1900 256". So is this just as good as using EFIexpress firmware bat?

Is it possible to start VemsTune in offline mode like you can with MegaTune?

vemstune might list the firmware as 1.1.23 if it doesn't have the 1.1.27 config ini installed. The same thing is true of 1.1.70, often it will show as a 1.1.68 ini file depending on what ini files are installed.

yes, in vemstune you can also tune files offline like you can with megatune.

How do go into offline mode in VemsTune did seem to be able to do it?

When uploading your firmware marc should I run temperature patch as well afterwards?

[Jonas_R]

Auditrigger - I have a quick question, should it be 56 or 58 at "TDC after the trigger"? See attached picture.

[A80Avant]

that is something best checked with the strobe light.

i think mine is 58 now but used to be 57 or something.

[Jonas_R]

Yeah oki guess that makes sense.

[Jonas_R]

Is there actually a place on the s2 where you can use the strobe gun or do you need to remove loads of stuff?

I've done it before by clamping on the wires off the power output stage. isolate the one for #1 cylinder, and a good strobe light will flash on it.

[Jonas_R]

I have not used a strobe light before but do just need to flash a the timing belt? SInce I'm 034 coils I have spark cables so I guess that should be fairly easy to setup.

ah, very easy then. you clamp around the #1 spark plug lead.

start vemstune with no serial cable connected to the ecu There is also a button somewhere that does it too, but I always just physically disconnect my serial interface. Then load a .vemslog or .vemscfg to mess around with a config.

[Jonas_R]

Thanks Marc that seemed to work, I had a saved config. But what if I want to set the basic AAN spark table that is in the vemsproject folder. Is that possible without the ECU connected?

Certain version share the same config so if you look it actually says firmware 1.1.27 and config 1.1.23

I'm using 1.1.70 but as it's config is the same as 1.1.69 so it shows firmware 1.1.70 and config 1.1.69

Config files are only created when there are different options in the new firmware AFAIK
