Wideband & EGT Gauge / VEMS EAW-52 power glitches

« Last post by turtleharry on June 25, 2018, 12:28:32 am »

Hi there,

I am new here and have two questions.
I am using a round controller for a two stroke engine with an LSU 4.2 sensor as well as the Vems EGT sensor. All is wired up with a rather tiny 2,5Ah gel battery (no more space for a bigger one).
Heavily tuned 2-stroke engines can be a bit tricky, so I want to check the temperature (EGT) and adjust the carburettor reading AFR/Lambda values whilst riding the beast.
Its all wired up and the sensor is heating up fine. But when I did the first ride around the block I noticed that the power of the controller drops out at higher rpm for a second. So the display goes black for this second.
All other 12V devices (speedo, indicators, USB power) seems to be working without any glitches.
Any ideas what this could be ?

As I am a bit of a newbie to this whole Lambda stuff and rather clueless I have also a question regarding VemsTune.
Do I need to adjust any of the wideband settings etc. in the software or are the default settings all good ?
The main display I have already adjusted.

Any advice is highly appreciated !

Harry

Software / SD card log "corrupted"

« Last post by RazOn on June 24, 2018, 11:32:18 pm »

I wonder if any of you guys have seen this before and know how to fix it.
SD card logs seem to be "corrupted". The car runs fine the whole time without a hickup, so I'm inclined to think it's only a logging issue.
This card worked perfect. I decided to erase all logs by formatting the card, then used the Erase command in Vems to get rid of any file structure, and re-enabled the logging. Now I get stuff as in the immage below; this is one of the better logs; most of them are completely useless.
Any pointers would be greatly appreciated

Thanks Maverick!

Still no luck with the sparc. I dont get this.
I cooked one coil, 12V batt on coil =30 min before coil-boil.
How can VEMS charge- and controll discharge, controlling only the coil negative (pin 36:35)

I tried measuring the amps, while testing the circut in vemstune. The current was constand aprox 300MA(), and actually fell a litle when pressing "test". At least something hapend. Diffenrent types of coils? Bosh "transistor based" coil, is says in german.

Shuld i use 1 or 4 ign. outputs?

Configuration / Trouble connecting VEMS to Bluetooth on windows 10

« Last post by dkritz76 on June 18, 2018, 01:00:18 am »

Trying to get my laptop to connect to my VEMS on my Porsche 944 turbo. I have everything hooked up in the car correctly, ignition turned on, and when I go to connect my laptop it cannot.   Open settings, select Bluetooth, and look for available devices. There are a couple devices that say “unknown device”. I believe it’s one of them as the person that builds these for VEMS for the Porsche crowd told me.   I select on one of them at a time and no luck.  Could it be windows 10 not compatible?   Should I pick up a usb Bluetooth dongle for my computer instead of using internal Bluetooth that is intagrated into my computer?   Any advice welcome.
