can i remove the low z injector relay and run my high impedance injectors ?? will the nistune controll high impedance injectors

how or where would i plug the aem uego wide band to nistune ca18det loom or to ecu ??


many thanks in advance

1. Pipe sizes are in the MAF selection list.... so it shows that 4" tube is 830rwhp. So that is the pipe size you need. You also need an airflow straightener in front of that about 2"

Please refer to our MAF tuning technical note (Nistune.com > Documentation > Tech Notes)

2. I don't know what this relay is or what vehicle you are talking about, given its not a Nistune tuning question either I cannot really answer that one

3. If you have a low impedance ECU (eg VG30) it will run high impedance injectors according to workshops who have tried

4. Refer to the AEM UEGO documentation for the unit and the CA18DET wiring diagram in the factory service manual for the O2 signal wire connection
