It can be placed as the original.
It snaps into the connectors of the motorcycle without cutting the original cables.

ΗRΜ ΙΙ SP62 HP
ΗRΜ III TT-F3 72 HP
The final tests of the ECU UNIT occurred with a motorcycle dynamometer with adjustable carburetors using unleaded gas 95 octane rating, 20 Celsius and 40% humidity.
The motorcycle that was used: NSR 250 mc21-mc18 as manufactured by Honda without adjustments to the exhaust system, kit, carburetor etc.
Tests showed great flexibility, from 1.500 RPM engine speed up to 13.000 RPM with better acceleration throttle from PGM-II/PGM-III
Technical Characteristics:
Operating voltage from 10 volts up to 21 volts.
Not destroyed as the PGM-II/PGM-III.
Not destroyed by a burnt regulator.
Manages the RC VALVE/TPS/ELECTRO VALVES CARBURATOR/OIL PUMP.

I bought this e.c.u unit H.R.M.TT-F3, is amazing, everything is works perfect. He man has done great work!
From the 1500 rpm to6500rpm as if you had a better from one PGMIII HONDA.
From 6500rpm to 13200 as if you had pgm f3 NH3 (is a same).
