Hi,

There does not seem to be any entry for long or short term fuel trim in live data and there is no option to read freeze frame data for time of error code.
Maybe I am doing something wrong.

When connecting there is an option for BMW or ISO, I have been selecting BMW, is this right?

Cheers,

Iain.

Which ECU are you connecting to?

Hi,

I think that short term and long term fuel trim are available in EOBD but the factory T4 tool doesn't show these. I can look at adding it.

I haven't yet implemented freeze frame data. Yes it needs to be added both in MEMS3 and in EOBD modes.

Ok, thanks.

Is the Fuel Correction value in live data related to fuel trim. I have a p0170 error code (fuel trim bank1) and am trying to diagnose?
