Fast EFI 2.051 internal datalogging issue/setup

[Eric Merryfield]

Trucks ECU got used to tune the dart, now its starting to datalog too early.

Truck uses a brake pressure switch for the two step.

Two step RPM is controlled by ignition box ie msd, we don't use fasts internal two step.

Now its starting to datalog the second the brake pressure switch is tripped(burnout)

I can only get it to datalog with it setup with manual trigger, and PA enable.

Could it be the firmware?

I think you should be able to seupt the internal datalogger without a switch ie set trigger point to 95% TPS, and arm it with PA enable, Aux 7 is a switch.

Thanks

Eric Are you Pulsing power or ground on the switch ? Aux 7 should be on a momentary switch to arm the system and set TPS to trigger.

Put switch 12v to pink wire for pa enable and configure to trigger on tps percent. Any time you make a change to data log configuration you have to select configure internal data logger.
