This afternoon (and most of the evening lol) I installed a B16A3 Intake Manifold, Purge Solenoid, a USDM TB that has a place for the MAP on the top (My JDM was on the firewall) and a USDM 5-speed P30 ECU. I switched these parts with the JDM B16A parts I had on my 92 Si swap. I have a question about the ECU change as it relates to the timing. I had my timing advanced with the JDM P30 and I'm wondering if the timing went back to a default (stock) by changing in a different ECU? I feel a difference (more low end and less top) from the other ECU. I don't think I'm just trippin' but maybe I could be lol. It does feel different. The whole change over (my first IM change) took me about 5 and a half hours (with a friend to help me scrap the gasket off). I busted my Knock Sensor from its housing (thats attched to the metal bolt) when I tried to take the oil filter off from the top (yes I felt dumb lol). So I thought I would have a CEL. I left the plug hooked up the what was left from the senor (nipple and all) and tucked it up in on the harness. I also loosened the nut attached to the block (for when I change it). No CEL??? I think it could be thinking its still good hooked up (it is technically). I'll unhook it tomorrow to check.
