My name is Dana, I live in the USA.

I have acquired the JDM type anti lag hardware for my Evolution IX. It seemed rather insufficient, so i went to make my own with more flow. I have 16mm pipes feeding the exhaust now, and a tial wastegate as a valve feeding from the UICP. My basis for insufficient stems from pictures of motorsports grade EGR ALS setups, typically found in the BTCC/WTCC/WRC along with other motorsports.

I am on the stock ecu, which is up for debate on whether or not it has what it takes. The questions and information I seek, are not if the stock ECU can handle it, however they are related to what the ECU must be capable of and hardware. I have google searched it for a while and occasionally this website comes up with results pertaining to EGR type of anti lag.

Terms that i have searched for that have led me this far are Secondary air system, SAS, Air injection, Air bypass, and many more. It took me a good while to see that people refer to it as EGR. The reason I read is typically EGR valves are used. This is never more true than if you see the EVO hardware, the valve looks like the OE EGR valve especially the seat and diaphragm.

So, enough of my


To those that have a functioning EGR ALS system:

Do you run a blow off valve or normal recirculating bypass valve to handle initial decrease in throttle postion?

Do you run an opening in the intake manifold of any kind other than standard ISCV/IAC settings? [[Jacked throttle or throttle bypas]]

Does the function of the ECU that allows EGR anti lag differ at all from standard jacked throttle or throttle bypass? Or is the EGR system nothing more than introducing the air after the motor instead of before it.

On a typical motor native to your Ford vehicles, is an ignition retard required? Also what about an ignition cut to allow more raw mixture into the manifold.

What is a satisfactory amount of ignition timing retard that would allow the post engine combustion to be effective?

211ratsbud is my user name there. I used to own a DBW 2.5l Wrx that was tastefully modified. My handle on NASIOC is Dubstar112, and the EVOM handle reflects the transition to the 4g63.

Thank you in advance for your consideration it has been no easy task to find the kind of questions to ask. There has been some help from ClaudiamXG, he exists on many forums, and I dont know about here or not.
