Nothing yet.
My old E30 316i with only 100 HP (this one has 105 HP) had much better performance - probably due its weight (only 1080 kg). My hope is that the difference between 318i and 316i is only in the software and that I will upgrade it to 118 HP after the warranty expires.
Yes, the only difference between the new generation 316 and 318 is the ECU and exhaust manifold. The engines are the same.
The 318 is a 16v unit whereas the 316 is 8v.
I think a little more work may be required to increase the performance of the 316 I'm afraid.
