hi all i have newbie question, i wish to dissable a couple cel codes in my rom so that i can unplug a couple of sensors that i no longer need - the boost control solenoid & the rear o2 sensor ( i live in the uk & so do have to worry about the readyness test you guys in the u.s have to pass) i understand from mr freds worksheet that i need to alter periphery fda bit 2 for the boost solenoid & fca bit 2 & 3 for o2 sensor. what i dont understand is what the values are in the worksheet under the bit (1/0) i assumed that they where the stock values in the ecu that i needed to change to dissable the cel codes, however whilst some match in my rom some do not for example my fda bit2 is already set at 1 in my stock rom (the same as the work sheet) whilst my fca bit 3 & bit 2 are set at 0 when they are set at 1 in the worksheet.can someone explain why this is?

at least thats my reasoning for different 1/0s in the map. just get it all setup but please remember that by disabling too much stuff u can turn off essential stuff in your car.
get the xml for your basefile from evo wiki it has the latest stuff updated including lean spool, etc.
just flash to your car and check fr CELs and then try again don't go disabling stuff randomly.
if u need help PM me or post a pic of ur bits here and i can take a look i have disabled my 02 successfully.

the bits were designed - actually discovered - in the USDM evos.

y u only have the two periphery bit tables?
you should have 6 in all.
try this link: http://evoecu.logic.net/wiki/Periphery_Configuration
remove what u got and put in the 6 tables (i prefer this method for future use as well)
NOTE: make sure u use ecuflash 1.35 and up

but 0 for the bits you would like to turn off.
in the case of rear O2 no act - ECU Periphery bit FEA bit 15 i think u set to 1
1 generally means on
0 generally means off
^^ not always the case but u may need to flash, start the car check for codes. switch off and start again and recheck for codes when the car is fully warmed. use evoscan to see the DTCs or CELs.

After reading through this thread I have come up with a question. Forgive me for my lack of understanding. I put a test pipe on my car and I got the CEL for it. If I turn off my rear 02 will the CEL go away, or do I have to do other things too?
Also what else will be affected by turning off the rear 02?
