I am enjoying reading these blogposts.
I have a question:
In your recent post on 3D visualisation ( http://z22sevectra.b.../ecu-12.html ) you show your VECandidate map (below)
and this map appears to show a dip in fueling and ignition around 2500 - 3200 rpm - I cannot translate Hungarian very well, so can you tell me if this was the map as you found it from your ECU, or has it been altered by you in a way that caused the dip?
I am asking as I have always had a flat spot in my car's power delivery around 2700-3400 rpm (or close to your map's dip) and after testing all systems, replacing sparkplugs etc. and doing normal OPCOM misfire checks, and reading other Z22SE websites I have come to think that the mapping in the Z22SE cars was created that way, perhaps to create an zone that was more friendly to emissions tests.
I read this post : https://www.astraown...t-84973.html and a user called Sonic Coupe put a link to a rolling road graph (see photobucket link in his post - http://i41.photobuck...h_scan00011.jpg ) that shows a big dip in the torque curve. The dip is in the same area as mine feels flat, and similar to the dip in your 3D visualisation.
If that theory is correct then your latest VEcandidate4 map (below) would smooth this dip out, and therefore is something I am interested in testing myself when I get my own software.
Please continue to update the blogs as they are very useful for me.
I have a MPPS v16 on order and will send you a binary when it arrives, for your binary collection.
