From what I know (and I know you wanted first hand experience, but hang with me here) the GTi-R ECU is designed to run 20 (maybe 21) degrees timing while in "timing mode". This means you need to adjust your distributor while in timing mode until you get 20 degrees timing. At this point the computer and the distributor are in sync. This is the way it was designed to run. If you then would like to advance timing further, you can "trick" the ECU by advancing timing past 20 degrees. Basically, the ECU thinks it's running 20 degrees, but you get more.
I apologize if you already knew all of this. It just seems like you're unclear as to how timing works.
Thankyou because I was a little confused on the whole timing thing. I know when my friend and I were tuning we had plenty of timing through the ecu, but we never checked the distributor. I finally checked my mechanical timing and found out it was only showing me like -30*, so I moved it to 15* and the car finally ran and boosted really well. Now I see why.... it was because the ecu and distributor weren't in sync with each other.
I really appreciate your post
Now I am going to put her back in timing mode and set the dizzy to 20* and see what happens
