a freind of mine swaped B18c GSR into his EK4 SIR originaly had B16a after the swap engine idle fine and no check engine but when driving wont pass 6000rpm it just dies after 5800, he used the same b16a wiring n did not wire the secondary butterfly valve could it be the broplem??? oh and he is using b16a ecu
Second, when he gets a P72 ECU, if the IAB isn't wired up, it will throw a CEL because the ECU can't control the IAB system and will automatically determine that the system is inoperable. I'm not sure if that will throw the engine into limp mode with the P72, but at least it will run very close to 100% properly up to 5800rpm (the point at which the IAB is fully open.
