Datsun 240Z L28 Stroker ITB EFI build S3E20 – Dual lambda sensors 240z
This setup was something I was going to install if I continued to use the standard twin Hitachi SU carbs. I want to run target AFR maps with the two available banks of injectors available with the Megasquirt MS1 V3 ECU. To do this I need to locate a wide band oxygen sensor (dual lambda sensors) for each bank.
The Zstory race sport header is a 6-2-1 header. The exhaust system is segmented and to mitigate the most risk of a contaminated signal I will locate the lambda sensors at the first collector for each bank before the first joint.
