1995 Honda civic hatchback 1.4i 75HP (90) 0-100kmh acceleration

Stock civic with throttle body mod, gasket from 90hp model.
Could do better start but tyres are bad, can shift faster but 1 to 2nd gear is grinding then. Overall great little daily car, longer gears are awesome for highway, tho it does lack in power quite a lot. PS if anyone knows if this stock ecu can be remmaped, please leave a comment. So far i could not find a way, i think its p3x or p3y ecu.
Filmed in mexico on a private road.
