I have a D16Y8 engine. Problem with my vtec is that its not engaging! This is what happens. I accelerate up to the point that my eninge is supposed to hit vtec which is at 5,600 rpm. And what is does is that when it hits the 5,600 rpm instead of hitting vtec, its hitting the rev limit. and the rev limit for my engine is supposed to be at 7,200 rpm. What can be the problem causing that is hitting the rev limit too soon when its the vtec thats supposed to engage. Help please, Thank You!

sounds like ecu to me!

start with the easy stuff first, check plugs, grounds, etc... then make sure u have enough oil. vie seen it way 2 often when your low on oil at higher rpms it wont make enough oil pressure and no vtec.
good luck

Thank you Very much! I have already changed the oil. So im figuring that it might be the plugs, grounds as you stated. Im going to check that. But thanks alot tho, I apreciate it!

yep. your right i went to the shop and they told me i dont have a vtec ecu since they in the past swapped the engine. the engine is vtec but the ecu is from factory and the car was non vtec so Where Can I get a Vtec Ecu? Any idias bro?

i have a few ecus, well actually about 100 or more. im sure i have one for you. and yea next time be sure to tell us the whole story. knowing that you have never had it engage vtec could have been important information. i was gonna suggest the Tstat ecu ground, but thats great to hear its just an ecu. i have many, i can one send out to you for about 50$ shipped. lmk

I need one for a d16y8 its a p2p for sure but idk the rest of the code if its an a81. etc. But i know its a p2p vtec ecu for a 96 honda.

you should be able to find the ECU for your engine in a junkyard. The only thing is that whoever swapped the engine might have modified the wiring harness to accommodate the new engine. You may as well find the right ecu, and get a wire map of your stock harness to help you wire it to the new ECU (or just visit boomslang or rywire to get a pre-made adapter)

yea i have a few p2p ecu's. jimjones07@sbcglobal.net is my paypal addy

yeah they have one for my car is a p2p manual and thats the one i need but the lady keeps asking me for the entire code for the ecu. Idk if it matter. or will it work with any p2p. Do you know?

if you know its trans type already then no, it does not matter, get it.
