Hello Eddy
Where should I put the Latency Time in 1?

Hello Paranasanches

Why do you think your connection issue has to do with the error described in this thread?
I suspect you have a setting problem, no interface problem
Your action is false

Whether you are with your software
(OBD2SPY, PCMSCAN, SCAM MASTER ELM e SCANTOLL V1.3.)

your Audi can read or not, I can not tell you
this is about Multiecuscan Forum

Hello Eddy
Where should I put the Latency Time in 1?

Hello Puntojtd1234

The latency is set in the Control Panel

Windows / Control Panel / Device Manager / Com port of the interface / properties / extended / Latency Time (normaly is 16)

thanks Eddy !

Hello Eddy
The latency values ​​are 2, the receive buffer and transmit buffer in UART port, I must change to 1 both?
However, I was able to connect after so many attempts, but the connection is very unstable and thereby disconnecting all the time.
I tried all the settings and all speeds ....
I think I was unlucky and had taken an interface that has a problem, maybe because I paid little (12 Euro).
I would buy another but wanted to make sure that the problems that I have said, is an exceptional case.
You know a reliable bluetooth interface to buy?
thanks again
greetings

Hi

Very curious that you can not connect?

Have you installed NET Framwork?


The resistor R04 was never your problem, but only the settings

I've had so far with 2 friends who were unable to connect
and it was always on laptop

Times used a different laptop

Hi everyone.

This is my new clone elm327 bluetooth with standart shape;

There is an R04 (121) which resists between pins 3 to 4 from right;

I connected through torque pro without any problem with my phone. But not tried with MES. Still needs to remove R04? Or may I first try it with MES?

Also does removing R04 effects usage in Torque or other generic OBD programs?

Thanks.

I'm a bit impatient I removed R04 and connected pin 1 to 7. It worked both with MES and Torque. Automatically detected com22.

But in some modules it throw out me to the main screen. Also I get "invalid iso code" warning. My car is Bravo 1.4 t-jet 2009

And I couldn't find LTFT and STFT (Long and short term fuel trims). What did you called them?

Thanks a lot.

Hello obk

Impatience is bad

I've written many times,
R04 or R12 and the resistor R2 or ........... Depending on the type of interface
for the CAN bus is a problem and is only for Multiecuscan!!

Share your Bravo (ECU, ABS, steering and xenon) you read in the original version of the ELM interface, despite the resistance R04

With torque all has nothing to do anything.

You may not immediately open the interface and remove anything without knowledge of why
