Avc-r

[NIZ30]

Just about to receive an Apexi AVC-R. Are these hard to install yourself? Anyone had any experince with these? I currently have a bleed valve, does this get replaced?

Next question...Do these work well? I run 1.5 bar boost atm. What I am mostly wanting from the AVC-R is to run 1 bar for 1st and 2nd gears. Does it do this well?

Last question(s)...I am also getting autometer a/f ratio gauge, oil pressure (electronic) gauge and shift light. Any hints or tips people can give me on the instalation of these?

Apexi AVCR went in no probs, hardest thing is finding holes in firewalls to pass cables. I made up some alum brackets for the MAP sensor and solenoid valve, mounted the MAP sensor next to the OE boost sensor (R32 GTST), and solenoid valve behind the air filter on the upright. Try and keep the solenoid valve as close to the wastegate actuator as possbile, the shorter the line the more accurate the control of boost. (I suppose you can just REMOVE ther bleed and place the solenoid in its place)

Only thing i didnt do was wire into ECU, but i removed kick panel and had all the wiring ready to go for mechanic. Cost me $40 to and 35mins to get connected.

I think im only using half the functions, but i seem to have stumbled onto a pretty good setting where she boosts pretty hard for a stocka.

Air/fuel meter is a pretty simple wire up to O2 sensor (Have you seen one in operation, they are pretty hard to make sense of depending if engine is in closed loop etc), oil pressure i cant help you.

Have decided against the AVCR (for now). But thanks for the help

With the a/f ratio meter, where exactly should i hook this up to the O2 sensor? Is this the airflow meter behind the air filter? If not, where can I find this in the engine bay?

I also bought an Autometer quik-lite shift light. Not sure where to connect the wire for the tacho feed. Any help?

O2 sensor is not the same as airflowmeter. Yes the air flowmeter is the black plastic cylinder about 80mm in diameter and say 100mm long that is just behind your air filter.

The O2 sensor is actually located on the exhaust, an inch or two from where the exhaust bolts to the back of the turbo. Depending on the type of O2 sensor there is typically either 2 or 3 wires, the Autometer manual lists both types and gives instruction on how to wire up for both types. (Bolts into the exhaust at 90 degrees)

I suggest you see the Autometer air/fuel gauge working on someone elses car before you install one as they are hard to read, as your engine ECU often flips form Open loop to closed loop (rich to lean) and you have to first understand this sequence if you hope to understand what the gauge is telling you about the tune of your engine.

Which is my next point, these gauges should never be used for tuning an engine.

Have seen the gauge in action.

The only reason I am getting it is cause I have lost my ashtray and am filling the gap up with two gauges. So the wow factor is about all i am using this for.
