Message: <blockquote data-quote="shiroitenshi" data-source="post: 2579214" data-attributes="member: 27518">This one is stock P30 ECU (other ECU, I didn't test so much, so dunno)If chipped, depending on the program, it can be very different for some of the needed requirements like speed and coolant temp.a) any check codes will result in limp mode. No VTEC.b) Solenoid not getting enough voltage/mampos/(not there, B20B stock block, lol). No VTEC. (or using VTEC killer cams/roller cams :P)c) Oil pressure not enough / or too low. Vtec solenoid opens, and no pressure present to lock the middle lobe in place. No VTEC.d) Speed below 40kmh (or about there) that's why when you free rev, vtec doesn't turn on. That's also why when speed sensor kantoi = No Vtec.e) Coolant temp not hot enough. Stock ECU needs the coolant to be hot enough before it allows VTEC to engage. Coolant temp too low, like 40 degs will not allow vtec to turn on. (that temp is like the first few minutes you start your engine in the morning. Too cool = no vtec.That's five I can think off.. what's the other 2?Hondata has a MAP reference for VTEC operation, but dunno if the stock ECU got or not.</blockquote>
