Engine Control Units with Aftermarket Support

Hi.

In another thread, the topic of "ECU lag" was discussed.

Rudi said he recognized it by the delayed deactivation of the daytime running lights.

My 1Z with 021 AF (MSA12) definitely does not have any after-running; there is no later clicking of the relay 109 that can be heard.

The colleague's ASV (Anti-Slip Valve) is lagging because it clicks later, and the LMM (Linear Motor Module) continues to be energized for a longer period.

Does anyone know when the trailing space was introduced (in the history of development)?

Because it is necessary for the shut-off valve .

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hi Martin,
It likely involved a switch to MSA15.

Best regards,
Rudi

The after-run sequence serves to check certain sensors and actuators after the ignition (Kl15) is switched off and the engine has stopped.
