yea. wow i have been searching for a while now and they arent easy to find i remeber the guy from the company i bought it from asking me if i has the correct ecu. and he was already pissing me off he had me sit there and wait as he was on hold for 20 minutes trying to fix his fax machine so i told him yes just so i could get out of there. so i believe he has one when i need it. what i did find out is the the seccond solinoid will kick in like my y8 but the first one wont do anything. so what i might do is get one of those vtec activation switches that i think greddy has. and hook it up to my first one. i am not sure yet. thanks agian for all this help trustdestruction i will let you know how everything turns out this time tomorrow night hahaha

VTEC activation switches don't activate the VTEC fuel and timing maps of the ECU, all they do is activate the VTEC lobes on the camshaft. They are worthless.
Just did some thinking... Hook your engine wiring harness VTEC wire to the VTEC solenoid's green/yellow wire and you will have regular 2-stage VTEC. I am not sure if it will engage at the optimal RPM for the camshaft inside of the D15B but it will probably be close enough.

ha yea but no one seems to really care are they are too busy i guess!
this engine swap is alot harder then i planned for it. but this is what happens when i have very little money and i am a very impatient person. if i would have waited a month i would have been able to get the actual 1.6L and not the 1.5
this should be interesting. ha like i said i cant thank you enough
i am interested to see what every one else thinks. and any ideas any one else has. but for now. i need to sleep because i have a long and busy day tomorrow trying to swap out my engine. ohh an other thing crossed my mind. and this may totaly defeat the perpose of buying the jdm engine. what if i used my y8 head? is that a whole other list of problems alot alot more work? and would it be worth it? or would it be better to buy the right ecu and stop complaining? hahha

Y8 head will create crank - cam timing problems I believe because the Y8 head is made for a 1.6L block and the shorter deck height on the 1.5L will change the distance between the cam and the crank which also changes the cam timing. You don't want to get into that sh*t, trust me... i'm in it right now with my D15B head on Z6 block... waiting on a new cam gear to correct the problem.
I would just drive it set up like I said in my last post and if you ever come across the P2J ECU then buy it.

Oh yea, when you wire it up the way I said, once you start driving it make sure that when VTEC engages it feels like a smooth transition and there's no "kick". If it's a smooth transition then driving it like that should be just fine and if you want you could just not get the P2J ECU. But keep in mind that if you get the P2J ECU and wire the three-stage VTEC up your gas mileage should improve and you shouldn't lose any top end power. In fact, I think that the first stage (the stage that would be missing with the D16Y8 ECU) on the three-stage VTEC may actually help with low end power now that I have had time to think about it... kind of the same reason that a D16Y5 (HX engine) makes more power than the D16Y7.

ok so i am about half way through the swap right now. and i havent run into any major problems yet. and the guy who is helping me. knows alot of toyota's and has been a machanic for 28 years. he says we should just switch the solinoids can we do that??
