Evap is what I have with the bolt. I'm guessing you left the bracket for egr and evap. Two 10 mm bolts.

I have a dumb question...
when u delete the EGR, and Ive gone thru, and disabled everything. I know I need to zero out the "high octane egr-enable advance", so should I zero out the other 3 EGR related maps???
base egr duty vs. load and rpm
egr normalization factor vs. coolant temp
egr duty vs. rpm (fault condition)

I didn't touch any of the other EGR tables, I did the Mrfred EGR enable/disable table and that was it.

You should be able to disable the evap in the periphery section. If your Rom doesn't have it search the forum and add it to your XML.

Yes because the ECU isn't adding random timing advance while the EGR system operates... hence timing is more smooth...

I removed my fuel pressure solenoid the other day. Disabled the FEA bit 7 (put a 1 next to it) and the car is still throwing the code (P0090 Fuel Pressure Circuit). Cleared the code and it only came back. Am I doing something wrong??

Tephra V7 96530706
