2003 Ford Focus RS - sensors question ?

[Jackstrath]

So iv been in contact with TVS and Beek,
TVS said the TCU should 100% be sending back a request for a cut or blip.
Beek asked me to log all Slave AN inputs and AN inputs so i did.
S1AN21 is supposed to be the blip request from the gearbox and you can see it on the logs but for some reason it looks like an afterthought once the gear has been selected rather than post paddle/pre gear change. Im going to assume theres something not quite right with the firmware as they have had that data for a few days now and iv not heard anything back.

without knowing what the slave inputs are used for, they'd mean nothing to me.

As stated multiple times, log the reasons for the torque reductions..

ie.

Il hopefully get the car out this weekend Stevie, is the screenshot you have attached what I should be looking to set up and log?

[stevieturbo]

log all the sevsrc parameters and it will tell what reduction is active.

Again, no idea how their coding works for the box, but that should identify why any torque reductions are happening

[Jackstrath]

Ok so did some logging today with i think all the sevsrc parameters logged.

Iv had a look but it doesnt really make any sense to me, says its hitting the engine torque limit and then anti lag on another
Beek got back to me and they seem to think the ECU isnt seeing the TCU read data, now theres only the canbus cables connecting the two and the box shifts as commanded by me which says they are talking to each other. No closer to figuring out if this is a ECU or TCU issue.

log was just over 1mb so had to pop it on my dropbox.

Not seeing any cuts or actions you'd think should go with gear changes.

I see the anti-lag fuel reduction...I assume you have anti-lag enabled and active ? You are not logging any ALS parameters to see.

Turn it off and try.

But unless their coding does actions you cannot see with the normal logging parameters, then it would seem something is missing.

Really they need to offer more info ?

[Jackstrath]

I didn’t think I did have ALS on, il turn it off but I don’t think it’s going to make much odds.

Yeh the help and support is very minimal. Think the language barrier isnt helping, but that’s no one’s fault. All I have got back is the ecu isn’t able to read the gearbox, which I assume is it’s not getting data back from the tcu.

The slaveAN inputs as I listed above is what I assume the coded firmware decodes the CAN messages and emulates them as inputs. But again there’s something not working there.

Or it could be a TCU software issue. But that’s harder to check as the required cable for the TCU is rather pricey, then I’d need software to allow me to remove or reinstall the TVS tune.

[stevieturbo]

What are the relevant slaveAN inputs configured as in the I/O 's ?

[Jackstrath]

I’ll have a look when I get home, do you mean input type vs there pin assigment?

[stevieturbo]

Yes, what are they used for in the pin assignments ?

They must surely be assigned to something ?
