wats up guys im having a huge problem with my car . first off i have a 1997 honda civic dx with the d16y7 and currently just swaped it out with a 95 honda civic ex (d16z6 vtec) i am using the original y7 ecu and the original engine harness preety much everything is original from the y7. the problem started with the car not wanting to turn on so i took of the timing belt realising that the crank sprocket was off timing at about 180 degress , i then aligned the sprocket to its arrow and i had the cam sprocket at top dead center. tried to turn the car again and it would not start and i started switching around the spark plug wires until it finally started! the engine was at a high idle and it kept jumping from 2500rpm to about 3200rpm and it smelt and you can hear that it was misfiring im sitting here wondering what the hell is going on ??

get a helms manual first off! secondly your y7 ecu isn't made to run a z6, its gonna run like **** till you get the correct ecu for it.

i kind of figured it was gona be the ecu and the harness but it was wierd because my y8 vtec was running off of a non vtec ecu??

Mitch965

also if you have vtec wired thats going mess things up more from what ive heard until you get the z6 ecu.

are you saying you heard vtec engage? if you are, you were mistaken my friend. can't have vtec engage if the ecu doesn't have vtec components in it. besides wtf are you doing taching your motor out when you know it's running like **** and have the wrong ecu!?

skieza97

wow i never quoted on here that my vtec kicked in or that i have the vtec engaged im not an idiot hahahh thnks for the help ill figure it out myself

Lol! Alright bro, first of all you need a y8 manifold and wiring harness and a p2p 5 speed ecu and you should be set, some of the plugs may not fit due to the z6 being obd1, so whatever plugs dont fit try using the sensor off of your y7 instead, should have bought a y8 instead, less electrical hassle and slightly better top end power... its honda tech, always prepare to get flamed, its part of learning if you said something that is totally incorrect or on the edge of moronic...

RoyBoy808

Oh and furthermore run the correct ecu, I blew one of my y8s up using a p72 (gsr) computer, unless your motor is built, just use the correct ecu... honestly I'd use the obd2a to obd1 jumper harness and run a p28 just to be safe.....

skieza97

roy boy thanks bro ill end up pickin up a y8manifold and harness but the p28 ecu would work fine correct its just going to be a daily driver i was gona boost it but maybe not time for it sense the engine was all rebuilt ?? and ok i got it!

Yo I know this thread is a post all on its on but anyone want to help me out? I'm fairly new to tuning. I am buying my first honda in a couple of weeks. All I know about it is that it's a 98 civic 4Dr i don't even know if it's ex lx or dx. I do know I would like to swap the engine later down the road. I was just looking for more info on basics that I should start doing to it immediately once I get it. Eventually I would like to put it in shows. Thanks a lot.

Haha alright I will. I'm sure I will just end up reading everything I already know. I am looking for someone to give me tips on starting to tune my car. I'm a noob.

kaysquared

cool deal the faq didnt quite give me information directly. But, if I have a question about something I could go there and firure it out. It's almost like a manual to any honda. Thanks a lot honda parts hero!
