OBDII drops within 10 seconds of connecting

[Cleggmeister]

Hey folks, new to HLT and just bought the Android mid-range app. Splendid so far - just need a decent phone mount for my RenaultSport Twingo RS133

Anyway, my cheap unbranded ELM327 bluetooth OBDII sensor won't stay connected to Harry's Laptimer for more than a few seconds. It's a cheap one but it works with Torque and other apps, so before I buy an expensive one I wanted to check I'm not missing something.

Attached pictures are outputs from Torque and ELM analyser, and from Harry's with the connection briefly on and then dropped...

I have gone "Expert" and switched ELM type from request/reply to "Automatic Replies" - this makes no difference.

Any thoughts please, or should I just drop £100-£150 on a decent mount and OBD, and maybe higher frequency GPS sensor? I don't track much - I just like messing around with gadgets and wanted a webcam equivalent!

Many thanks for the support!

Please have a look into the FAQ on Debugging OBD connections. These drops usually mean LapTimer is receiving some invalid input. Well possible this is an adapter incompatibility. You may try Expert Settings ‣ OBD Tweak / Adaptive Timing ‣ Enabled before doing a full logging. The "Optimized" feature frequently fails for car and adapters not fully supporting the OBD / ELM standard.

Thanks Harry, will do.

Adaptive Timing Enabled - regrettably no change, connection drops in 10s or so. Please could you link me the FAQ and I'll try it all over the weekend? Many thanks from Scotland!

It is in the FAQ section on this forum. You can use the forum search option too.

Since I bought the OBDLink Scantool MX thingy I have not had the problem - everything just works - hence it's worth buying a better ODB dongle rather than trying to make a $5 ELM327 piece of junk do anything. Thanks all!
