anyone have this problem? when I'm datalogging or have it connected it just mysteriously disconnects. any fixes for this?

thanks

 

omg dont get me started with this

does your usb cable have ferrite cores on it? Are you using a Dell?

 

yes, and yes its annoying as hell! it connected so good before..

did you end up fixing your problem?

 

mine's fine w a hp, don't know what ferrite cores are...

 

been using my computer all day. Macbook with windows 7 on bootcamp.

 

What is the part number on the spark plugs you are using?

 

NGK 2668 (BKR8EIX)

it was working good for almost a year, and for the last two months this started happening. the only changes were I got a trunk battery relocation, and I had my head built around the same the time.

I had also noticed that my ELD input, that reads my PLX wideband is not reading properly anymore even witht the voltage correction. I'm not sure if that is related.

I wonder if this is a ground issue, but I have checked and everything is grounded properly.

 

Unless there is a good reason to relocate the battery we recommend that it is kept in the stock location.

All ground wires need to be unbroken lengths of wire with both soldered and crimped at each end. They need to be securely bolted with bare metal (ie unpainted) under them - they will not ground through the bolt threads.

The battery positive also needs to be one length of wire (unjoined) from the battery to the fuse box also with both soldered and crimped ends.

With the car running take a multimeter and measure both the voltage and current flow between the battery negative terminal (not the chassis - you may need to extend the multimeter lead) and several ground points, including the ground pin of the ECU (pin A4/A5) and also the metal surround of the USB port on the KPro. Voltage should be < 0.005V and current < 0.001A. Measure voltage first and if it is high (> 0.050V) don't measure the current...

 

My Dell worked great when I was N/A but as soon as I went boost it went to shit. I've tried everything and nothing will keep it connected at full throttle. My TV2 works 100% with no issues so I've pretty much narrowed it down to the Dell.

MacBook with BootCamp will be my next setup...just waiting on Apple to release their new MacBooks.

 

Why don't you guys actually address this as a known issue instead of treating us like we can't read? This is a known issue with Dell laptops...the least you could do is put a disclaimer on your site or the help file if you're not going to try to fix it.

Sometimes your customer service makes me question how you make such great products in the first place.
