Rb25det correct timing angle

Recommended Posts

Hello,

My car shows in Link G4 ignition angle parameter BTDC around 5-6 on idling (around 1000 rpm)

What  correct timing angle should be in rb25det then. Is there any corelation to this what Link g4 shows?

How to set up the correct timing angle?

Actually, I just realised that you were talking about a Link. What I said could still be true, but because it is an aftermarket ECU with quite  few things that you could have wrong (either in the ECU or out in the hardware), it's pretty well impossible to do other than guess what is going on.

It is doing that because the ECU is retarding timing to try to pull the idle revs back down. This suggests that your idle control motor is not working.

I personally have posted many thousands of words on this subject. Go searching.

 

i mean how to set up the crank angle sensor, what deegrees it should be on crank pulley using strobe light.....? That was my question

You need to lock the timing in the Link ECU then sync it, then unlock it.

It could be pulling timing on idle as part of the idle strategy.

Also if the car is running fine, don't touch it. Your tuner may have tuned the car with timing out so the entire map has been offset by that.

Base timing offset will need to be checked. Link help file in the pc link software has the procedure in there.

I've set my link ecu up for 15 degrees base timing and have an idle ignition map as that could be something that has been setup. 

If it has just started idling high start looking for leaks after the throttle body. 

Pm me your tune can see how it's been setup
