Everything is back together.



With these last few parts, I am officially done with the engine and bay side of the build. Unless anything comes up in the tuning process.



When I took the car out for a few hours on Friday things felt really good, especially after I got back. The idle was buttery smooth. BUT pulling off from a stop was always really jerky. Throttle response was lurch-y and would sometimes oscillate. Kind of like when you were learning to drive a stick.

I re-flashed and added back linear throttle, dropped idle to 900, and went out.

It takes a while for AFR's not to be 19-20 when you are sitting still, which makes the car idle like crap, as it runs too rich. It starts to creep back down to ~15-16 at idle after driving around for a while. I think it just takes a while for the car to properly learn it's new smooth idle especially with the added RPM.

Linear throttle solved the lurchy pull aways from stop. Seems to be great now. I noticed the base custom map boosts to 18PSI so we have a lot more room as we go into revisions and start the tune.
