Eliminate EGR and ACV Auto FD
Hi
I'm working in a auto FD 93, and want to know if i can eliminate EGR and ACV to simplify a little bit. And if i eliminate this, did i receive some error code from ecu, or engine light, etc? What's the best approach to do this right?
Best Regards

If your car doesn't have an electrical connector on the egr, you can block if off with no ill effect. If it has a connector it will throw a code.
Disable EGR
Why do you want to eliminate the ACV? That controls your idle. Did you mean AWS?

I think that ACV don't control the idle, i think is the ISV that control that. I eliminate the AWS to.

ACV has nothing to do with idle, it is emissions.
If you want to eliminate the smog pump and ACV, then you are better off actually doing a simplified sequential vacuum routing.
You should install an idler to protect the engine bearings Pulleys & Belts (93+ RX-7)
You will need to install 330ohm resistors in each of the connectors so that the ECU does not throw error codes. Really the best this to do is install a PFC with our Automatic PFC adapter, then you can do whatever you want to the car, just like the manual trans cars, no resistors or error codes and the ability to tune the car.

If i eliminate the AWS, did i have to install a resistor in the connector?

Some people refer to it as the air control valve or idle air control valve. Its the same thing. Mazda calls it BAC as well. The AWS (accelerated warmup) can be disabled by disconnecting the vacuum hose from the actuator on the intake manifold, and plugging the nipple on the solenoid. You also want to cap the hose that went to the inlet elbow. If you leave the actual solenoid plugged in it will not throw a code.

People have claimed to not have issues with just unplugging the AWS (Accelerated Warm-Up System) without a CEL, it may just be a stored code. Easy way to check is jumper the diagnostics box.
The ACV is specifically the Air Control Valve on all generations
The BAC is Bypass Air Control for the FC, the similar item for the FD is the ISC Idle Speed Control (FSM F-81)
