I looked at a 94' Civic Si with a USDM B16A2 out of a 00' Si.I/H/E Skunk2 mani..Hes running a PO6 ECU Skunk2 Chipped with no Knock sensor.Its running rich as hell and theres black chaulk all over the exhaust.

The car drove fine, idles good and everything.I just want an ECU that runs stock pretty much with knock sensor since its going to be my dailey driver.

Which ECU should I run?

 

try getting a p28

 

Whats the difference power and MPG wise between a JDM P30 and P28?Doesnt the P28 have to be chipped?

 

most likely the P28 will have to be chipped

 

p30 is the ecu that goes with the motor, the p-28 would have to be chipped.

 

the usdm p30 is best for you car but vary rare to find. they're alot of jdm p30 but you car will run alot richer as well as the p28 chipped. a chipped p28 will be cheaper and easier if you would like to go hondata later on.

 

How do you know if your running to rich?Even just a little.I dont want to waste gas if it doesnt make any more power.


Thanks

This guy is having a JDM P30 chipped to have a 8500 Redline and the speed gov. removed and the O2 Sensor disabled.He said hes not messing with the Air/Fuel.So its going to run rich with the stock setup?

 

hook it up to a wideband 02 sensor.
