It’s been a few days since my last post but I have been researching information about my ECU, VTEC and why my engine surges while giving it gas. My first ECU was giving me code 19 which was an auto tranny sensor, so today I went to the wrecker and picked up a proper 5 Speed ECU and a VTEC Pressure switch. My first ECU was P28-C50(auto) the new one is a P28-C02(5 Speed), to identify your ECU go to Rywire.com, as they have a write up page on how to identify your ECU. They sell wiring harnesses for VTEC D16Z6 Swap, B, H and other Wiring harnesses that you might need for a custom swap and they also have a great writeup on how to wire up your VTEC to your ECU. My VTEC should be operational soon as I got the pressure switch today so it’s just a matter of feeding the cables from the plugs to my ECU. My car has been idling kinda funny and stumbling when given light throttle; I did some research about this and found out that it could be a case air pockets in my coolant or a bad or dirty IACV (Idle Air Control Valve) which is located at the back of the intake manifold. I will try to look at both tommorrow or next day and see if i can fix this problem. I also got my Megan Racing 4-2-1 header today so I managed to put that on and now the engine looks really sweet.
