Dave posted a pretty good write up on his EVO and explains why many owners are reporting "not much after 5000rpms" and how to improve the high end acceleration.

Pretty sweet. Also, if you don't know what you are doing with A/F ratio tuning; use an experienced tuner and 93 octane gas .

Also, his new exhaust systems include the rear O2 bung for the ECU and a O2 simulator sensor for use with a test pipe. Also, I do realize that Al and other turners have found the AFC to work very nicely with the EVO VIII ECU.

Have fun.

Sweet! Now I need to get my hands on an AFC! Do I need any supporting mods with the AFC? ie. boost gauge, controller, etc.

AFC-Air Fuel Controler.

Dave Buschur is running 12-12.5?

IS that safe? Seems very lean. What is the limit for Eclipse's 4G63?

 

AFC= Air/fuel controller.

That's great info man thanks for the post. Only bad news is the octane requirements. =( I have **** water for gas and wouldn't be able to run that on a normal basis. What a pain having a sports car in San Diego.

 

yea sorry, i have sunoco 94 octane here
, how much is that Afc? install?

12.5:1 is the sweet spot for the 4G63 - at least it is concerning the D.S.M.

 

Can somebody post some SAFC values on here to make the car run at around 12:1 a/f?

 

Great info!!!

 

i have 2 brand new apexi safc in stock..

$270 shipped.

let me know if you need them..

 

Let the *** kicking begin!!

 

Again, can somebody get me the values/settings for the SAFC to make the EVO8 run at 12:1 a/f? PM me if you don't want to post.

Thanks in advance.

 

I want one. Let me know what I need to do.

 

I'd love to see some before and after 1/4 mile results from adding/tuning the AFC.

 

Hey what do you guys think about the Power FC? Just curious.....
