Time for an update!
So, the big calipers turned out to have seized bleeder screws. The shop I brought my car to tried everything but couldnt get them out. They recommended taking the calipers to a machine shop to have them drilled out and retapped.
I dont want to mess with one of the most important part of the car so I sourced another set of calipers. They just came in today so I'll be starting over with these.
In the mean time, I decided to do a resonator and secondary cats delete...
It already sounds much better, but way too quiet for my taste. I'm planning on replacing the muffler with a 135i muffler.
Next, I decided to tackle the 3-stage intake manifold.
Before...
During...
With the airbox out, I also did the charcoal filter delete.
Found a pretty bad leak at the eccentric shaft sensor which I'll need to take care asap.
Back together...
Hacking time!
I flashed the stock 130i software and off I went for a test drive.
First impression: holy sh*t! It cant be THAT much faster
I'm guessing the adaptations were reset and the accelerator pedal is much more sensitive. At low rpm the difference is HUGE. From 2k to 3k there's a bit of hesitation and from 3.5k it picks up nicely.
When I'm done tinkering with the exhaust and intake, and maybe do the MILVs, I'll flash with a proper tune. But for now, this will do
