Your probs getting sick of me asking now, but this whole sai/ EGR thing is confusing. What is it that needs mapping out, the EGR canister thing that you take off? Then leave both the solenoids plugged and and you get no engine light at all? Just need to find out the associated codes if I do what you have done. I'm guessing I won't get codes because the solenoid is plugged on, except the codes associated with the carbon canister flow etc
Hope this makes sense! Haha
