Software / VemsDisplay Android Bluetooth but no data

« Last post by M3GTttHulk on July 15, 2022, 05:46:08 pm »

Hi guys,

Vems V3 running on firmware 1.2.43
Powered bluetooth adapter

Android tabled finds the bluetooth adapter, VemsDisplay connects (green connected) but it seems to be connected also when the car is switched off.

Switch the car on, power up the V3 but no data is beeing fed to the VemsDisplay

Any ideas?

Ignition / Re: "Short" VAG coils don't want to fire..

« Last post by ScareMercy on June 30, 2022, 09:09:46 am »

I've tried a new Audi R8 coil yesterday to see if it makes a difference but that one also doesn't fire.
However, upon measuring the voltage on the signal wire during rest it reads 0,55V while it should be a ground. Is this voltage too high for the coil to reset itself?

Ignition / "Short" VAG coils don't want to fire..

« Last post by ScareMercy on June 28, 2022, 12:13:09 pm »

Hello,

I've tried getting my "Short" VAG COP's to fire since a couple of weeks, unfortunately without any luck. All 4 COP's are brand new, they're BERU ZSE030 coils.

So far I've tried the logic level outputs and stepper outputs, checked the pinout knowing it is differtent than the longer VAG COP's (Pin 1 and pin 2: ground on cylinder head, Pin 3: 12V,
Pin 4: Signal from VEMS). I've tried testing the configuration using a LED; the LED blinks briefly. I've also tried supplying 12V to the signal wire of the coil for a short moment; the coil fires on release.

So far so good, except that the coils won't fire in test mode or while cranking the engine.... I've tried contacting my VEMS supplier and have gone through the whole setup again, but still no spark.

Is there anyone that can point me in the right direction? I've been at it for 3 weeks now and am completely lost in what to do now.

Configuration / Re: MAT /Intake Temp sensor M52 BMW

It was the one that comes with the BMW M52 kit open air style "breu" i believe ,
Now since this post I noticed it was set to default and I changed it to a vems pre load and temps are spot on with ambiant and car seems to be running fine within the arf  14.6 just driving and under boost a little jumpy but in the 11.2-11.8 with 20psi (butaround 11.3 average)

I guess my question is should i be worried?   i'm new to this and had a guy tune it for me

Which sensor do you have?

If the temps were off when it was tuned, fixing them now will require a re-tune. If they were accurate when it was tuned, fixing them to accurate now would be no problem.

Is there any VEMS development still active?

Yes, for sure. But they aren't spending their time on here.

Just scale the speed sensor in MPH if that's what you want and ignore/remove/change the units for the gauge.

For oil temp, add an analog gauge for the channel your oil temp sensor is connected to. Or you can use AIM mode, but triggerframe offers more ECU data.

I noticed my intake temp is reading higher then it actually is  ambiant temp is 10C and car is stone cold charge pipe as well, but laptop vems app reading 50c and driving in that air it goes down to 37c but that's it.    now i noticed i can change it in MAT Curve setting to make it correct but,   
If I do so will I need a re tune?

Did it more than 20 days ago and not a word from anybody. Seems like developers do not monitor wiki anymore. Is there any VEMS development still active?
