I just finished reading through most of this thread again and I'm confused and enlightened haha.
I pulled my ssafc, cleaned all the connections/wires up and soldered everything since thats one of the pieces of advice I saw multiple times.
This switching over/over pressure thing is still an issue. Sometimes it seems like it happens so smoothly and other times it seems not to happen at all. When it seems to not switch over or get hung up my afrs go all the way lean and I have to let off the gas, this seems opposite from what other people are experiencing? If I go half throttle it is much more likely to stay in acceptable afr range. I know this just came up a couple pages back and much earlier in the thread but unless I missed it there wasn't much conclusive info.
Another thing I think I need to figure out is how to get a smooth data log on a third gear pull. Whats the best way you guys have found to get consistent results? What speed/rpm do you start at?
Oh, and I over-wrote my best map so far FFFFFFUUUUUUUUUUUUUUUUUU
I'm experiencing the same thing at the moment. Have you tried calling split second yet? They're usually more than willing to help diagnose problems.
