elm327 with toggle switch

Post by Galaxysong » Sun Apr 09, 2017 10:53 am

Hello all...

Anyone have experience of using the elm327 with HS/MS toggle switch?

Done a pump learn and injector pilot learn on my transit 2010, all procedures were successful.

However, FORScan repeatedly prompted me to toggle the switch at various points during the procedures...

I Just got a new elm327 v2.1 FTDI Chip model with the toggle as stated but was wondering if this was a fault with the elm or is that normal?

Thanks

Perfectly normal, during a complex procedure you will need to swap form one CAN network to other (High-Low) the toggle is just a cost cutting thing.. other manufatures have autoswitching components that does that automatically...

Thanks for the reply bizkit I was concerned if the elm was good or not.

FORScan reported the elm327 as a genuine v2.1 model.

Can I ask...When you said, "the toggle is just a cost cutting thing.. other manufacturers have auto switching components".

Do you know if there's an elm327 for FORScan with the automatic features?

Thanks again

Just to name 2 OBDLink MX, ELS27 but there are many others, just look around for Forscan compatible devices and look for no togle and CAN MS support :D thats what you need...

ELM 327 is not capable of auto switching. But you can mod the adapter for auto switch with a minature relay and some more components. There is a schematic here in the forum somewhere from FORScan team.
But this modification will work with FORScan only.

STN1170 based adapters like ELS27, Obdlink MX or Viaken "ELM V3" use another microcontroller that has more inputs than the one in the ELM 327 chipset. Here one input is hard wired to HS-CAN and another input is hard wired to MS-CAN. Microcontroller switches between inputs automatically if data from one of these inputs is requested.

Finally got around to checking out the devices you suggested. On the websites for the OBDLink MX I note there is no mention of HS-can.
Does the OBDLink MX support HS-can? I don't quite understand the protocols yet, more study required, but could you advise if I am thinking the right thing...

Thanks

Hello again...I have finally managed to save up and buy the OBDLINK MX.
However I seem to be having a problem connecting to my wifi.
I would be grateful for some advice.
Thankyou
