1. Pretuned E-manage Ultimate & V-manage
2. Open pod air filter
3. 2.3inch APEXi exhaust system (with catalyser still intact on the OEM header)
I didn’t expect the power will be 3 ponies shy of 200whp and torque of 19.6kg/m as I have seen lower figure before on a 2005 DC5 with same mods. The air-fuel ratio reading is also quite smooth thanks to the supplement of E-manage/V-manage combination. Yes the pre-VTEC mode is a bit scruffy and there’s a slight drop during VTEC engagement (note that the VTEC point has been lowered from 5800rpm to 5200rpm by those piggybacks) but the power generated wasn’t disappointing. One thing for sure I’ll make full use of the E-manages and V-manage to fine tune the graph and subsequently tweak few more horsepower from the engine.
The first step shall be: de-cat the exhaust with test pipe before getting an aftermarket header!
The verdict: K20A is amazing.
