Custom PIDS or MAZDA DPF%

Post by carlus » Sun Sep 03, 2017 3:42 pm

Hello,

This comment is addressed to the forscan development team.

For cars with Diesel Mazda engine, at least for models with MZR 2.2 Diesel engine, there is a formula, which starts from a PID, allows to know the percentage of accumulation of the DPF. This value is very important because if controlled, it allows us to get an idea of ​​when the car will need to do a regeneration.

I have seen several formulas to calculate the % accumulation of the DPF and I think there are two very similar although I think the most correct is the first. The formulas on PID 22042D, are:
- ((((A * 256) + B) * (100/65536)) * 100) / 10
- ((((A * 256) + B) / 628) * 100) / 10

And now the question is this:
Can you add in forscan the option that we can include custom PIDS? Otherwise, could you add this new custom PID in forscan for MAZDA cars?

Regards, and thank you very much.
