Rb3025 Base Ignition

[Skeeed3r]

Hello folks,

i build up a RB30 block with an RB25 Neo head and have some problemes with the base ingition at idle.

What a ignition timing are you have at idle ?

Thanks for help

15deg BTDC. What sort of issues are you having?

Edit: That is the base timing setting. I see around that but it obviously varys as it is in closed loop idle. Values in the range of 10-20deg would not be uncommon as the engine is trying to stabilise itself at a set RPM.

It uses a combination of ignition timing and air control to do this.

Depends on the ECU.

Factory / Powerfc - Unplug the TPS and it will lock at 15degrees in the ECU, then you can adjust the CAS to get it right.

Link / Others - They have adjusters in the software to lock and adjust it so that you don't have to adjust the CAS.
