ok so i have a 96 ek sedan. Swap is a 96 gsr with obd2 ecu. I have all the
bugs worked out except with the EVAP system. AT 1st i had a code for
FTP sensor voltage for i followed ffs squad to trick the ecu in thinking I have a FTP sensor sense my vehicle does not have one. After i did the FTP trick
now im have cel code p1457 evap canister system leak.

IM using stock ek evap canister and gsr purge solenoid.

So do i need to use a integra gsr canister, or could it be that i just have
a bad purge valve?

Any help with this evap system would be great.

I will be switching to OBD1 but i still need to pass emission so i have to
be able to pass with a OBD2 ecu.

 

no one?

 

Yes any1 have same issue.
Po441 and Po171 came on. I'm using Ek purge . Do I have to us gsr?. Plus what about canister?
