7 ECU -> 6.5 Car (EGR + EVAP CEL's)
 

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

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
{thumbup}

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 :)
