my friend has a d16y7 motor tuned on a ls ecu n its runs hard but why does itr run so hard it doesnt run harder than b16 or gsr but ive seen it keep up with a ls but why does a ls ecu do so much?

 

bump.

 

LS ecu runs a 1.8liter fuel map on the y7, which is 1.6liter.
Good friend of mine has it on his EG
thing runs pretty mean

 

so lets say i want to get a ls ecu would i have to get it chipped or throw a program inside

Nope, not as far as i know.

But keep in mind, my friend is using a Z6 intake manifold, not the stock Y7's.

 

ok thanks anybody else? know anything of this?

 

What do you mean it runs hard? Like has a hard time to start, hard time to go, hard what?

Friends EG hatch runs 15.6, Y7 block and head, Z6 IM, Z6 Trans, and LS ecu.
It runs unnaturally strong for a y7 motor

 

theres more torque it feels like it just feels different

 

I say throw it on a dyno with both ecu's and tell us what you find out.

Exactly, it just runs much stronger than a standard y7 with its stock ECU. Cars with Z6's and Y8s run Low 16's, High 15's. He hits 15.6, no vtec, lol.

 

my friend setup is ls ecu ebay headers and thats it on a d16y7

 

but i currently have a d16y7 in my coupe would i have to get a obd 1 or 2 ls ecu?

Regardless, you cant run it correctly with the Y7 intake manifold, it uses a 3-wire IACv. The LS ecu's ( and almost all honda ECUs, lol) read for a 2-wire IACv.
Yes, there are ways of converting it, but i think thats only for if you swap manifolds (that have have the 2-wire IAC) and ECU (reads for 2-wire IaC) while still using your stock y7 harness that has the 3-wire in it.

 

so what kind of intake manifold could i get i got a d15b7 intake mani laying around some where would that work?

 

Either D16Z6 or preferably D16y8, because your car is OBD2, and you have the extra vaccum lines for the EVAP system. Remember to get the matching Throttle body as well.

 

thanks for the help!

 

Does using a LS ecu on y7 really feel stronger??
