Lateral g force based bank trims, possible?

[Sean]

Hi, has anyone got any ideas on a way of achieving lateral g force based bank or cylinder trims? This is for a roadrace application with individual runner injection and high mounted injectors. I don't think this is possible with the M800, but someone may have a clever workaround..

Thx.

While you can't have a bank table, you can have a table for each cylinder based on Lateral G Force. Just put the same table into all cylinders in the same bank. Use Axis Setup to specify the Lateral G Force channel, and the break points you want to use.

Would you mind sharing what kind of mixture change are you seeing with Lateral G Force?

David, thanks for that. I'm already using the individual table for cylinder trims, may have to reconfigure these somehow. I'll get some data for you after the weekend, at the track now.

If you use La Control set up La1 and La2 sensors by bank and if there's a difference at high latG there will be a bank to bank correction short term. See general setup/fuel/setup /bank trim mode for cyl number setup (odd/even or consecutive) for each bank. Sensor setup/Lambda cyls to assign cyl #'s to La1 and La2. Now you have La control trimming by bank.

Thanks Scott, never got near thinking of that.. Sean
