Changing EK4 ECU - from P72 to P2T

[MACHAN86]

Hey guys, I recently bought a 96 EK4 which is supposed to have a P2T ecu. But it has a P72 ECU which I was told is from a DC2R. Vtec currently hits at 4500 but it starts to pull harder at 5500. Saw somewhere that this could be because DC2R's have 2 butterfly valves. Currently the car chews fuel (350km to a $70 full tank). I have found a P2T ecu out of an EK4, but I just want to know will it be a straight plug and play? Or will I need to get it programmed. Also will this be better for the car and will I notice an increase n power? Any advice would be greatly appreciated. Thanks in advance.

I thought you can't program/tune standard ECU's ?

Op

P72 is the dc2 vtir , which yes has dual runners and hence a audible difference in revs and again when vtec engages. This is only relevant , IF your car has a
B18c2 engine in it ! If its a b16a2 or even a b18c or b18c7 this is not the correct ecu
Tell us the engine code ( found on the engine block just near the clutch slave cylinder)

Don't forget to disable the imobiliser on the board.
See DIY for instructions.

thanks guys.. it's a b16a2. Can you please send me the link for the DIY TODA? I can't seem to find it. Thanx

Also, I have bought the new P2T ECU now, so what steps do I have to take when installing in into my EK4?

And does anyone know when vtec engages and cuts out on this ECU?

got the same probs 350kms in 45L of 98octain, but mine got aftermarket injectors.. what mods do you have in there..?

stock b16a2 hits vtec around 5.5k RPM..from views..

Replace the aftermarket injectors with OEM injectors & check function of O2 sensor.
Or, get a programable aftermarket ECU & have it tuned to suit the aftermarket injectors.
