Hi Guys,

I have a friend that is getting:
P0433 evap system purge control valve circuit.
P0403 EGR solenoid.

He has a 7 ECU in a 6.5 Evo, he is running 99860003 as his ROMID.

As the fix is it correct to change bit15 of Periphey2 (0xFCA) to 0?

This wont affect WOT fueling or anything will it?

Just checking

Cheers
D.

 

shouldnt cause any problems with WOT fuelling.enter 0x0a89 in perephery 2

 

tell him to use 90550001 its a ralliart rom JDM and has most of the error codes disabled I sent ya a basemap copy I use for earlier evo conversions and definition


or set perephery FAA to 56D0 its the 3rd bit on the high byte to disable egr

 

interesting, 56D0 also turns off the immobiliser. Dave, I just usually turn the whole of FCA off and havent had any complications.

 

thanks doodz

 

6 doesnt have immobiliser

 

no but some 7 ecus have them

 

I am not surprised they dont, its just that hex bit turns the immobiliser off and thats the only thing I saw mapped on that one. I didnt realise it affected the EGR as well, I'll have to look closer at the periphery map worksheet I guess.

 

there is an EGR test on FAA but the roms iv seen dont have it enabled.when i converted my evo2 to an evo 8 4 plug ecu i had to disable ecu_perephery 2 FCA bit 15.which disables the P0403+P0443 CELs.im sure the 7 ecu is the same.

 

iirc changing FCA from 0x8A89 to 0x8D89 will stop the EGR fault code

btw never seen rom id 99860003

 

we have 99.999999% jdm 7s lol , dont get fq300 here
