Default P28 for a D16Y8

I’ve searched many of forums, but couldn’t find an exact answer. I’m going to boost my D16Y8 in a year or so. Because I don’t have the funds right now, my plan is to “collect” the parts I need for the boost project over the next year and install some of the parts as I get them, but only if I can use them without hurting my current setup (basic I/H/E). For my first purchase I was thinking of an ECU, maybe a P28 or the P06 with an OBD2B to OBD1 harness. Kenji211.com is recommended over at Honda-tech as a place to purchase them from.

So my question is, can I use one of these ECU’s in my current setup, just plug it in and go? Will I be hurting my performance with one of these ECU’s with the current setup? Is it recommended to have a custom VTEC engagement or just leave it? Obviously in the beginning I would like to “collect” parts that I could use now. I’m open to suggestions. FYI the P28 would have a D16Y8 base map.

Thanks for your patience,

Jeremy

you can use it with your current setup but you must have a chipped p28 or p06 and run a y8 stock tune and not a z6. the reason you can't just plug your conversion harness in and run the p28 is that the base timing is differant with the d16z6 and the d16y8. you can run the stock p28, meaning it will start and drive but just don't do it. and also jdmshit.com has good prices on the harness, $75 shipped.

Jeff,

I learned that Kenji211.com will chip a P06 for VTEC and it will have a D16Y8 basemap. So with this setup and can run it and have no problems, basically it will "emulate" my current ECU correct? However, I won't be gaining anything.

would it be recommended to have the VTEC at 5000 RPM?

in theory you shouldn't have any problems and it should run fine. i have been messing with my vtec between 4500-4900 but i don't see why 5000 would be bad, some people like it a little higher. i can't really tell the differance from it being high or low so just put it when you want it. how much is he chargeing you for a chipped ecu and base?

The harness is $85 shipped. A Hondata s300 prepped ECU can
not run one of my chips. It is setup differently.

In any event, the Hondata s300 prepped P06 and a OBD2b to
OBD1 harness is $235 shipped.

The price would be the same if you choose a chipped P06.

Jonh over at http://phearable.net doesn't recommend I get an ECU until I'm ready to boost.

mtber: Jeremy,

I dont recommend you purchase the ecu for your y8 until your ready for boost.

Thanks,
John Vega - Phearable.net

gimmezell: If you have time can you expand on that? Will it hurt me if I use it now? Is there anything that I can buy and use now? Just as long it doesn't hurt me in anyway.

gimmezell:
Sorry keep bugging you. One more question. If i'm not expecting any performance gains from the P28 install in my current setup, would you still not recommend it?

mtber: I just dont think your car will run very good on our all motor y8 basemap :-)

mtber: Our y8 turbo basemaps are much more developed.
I will take John's advice and not get one until I need it.

you can purchase a chipped ecu with a basemap for around $120, and then the harness is $75 shipped. thats why i was asking how much he wanted for it. you shouldn't have to spend more then $195 on this, so $235 sound slike way to much. and IMO hondata is over rated, use crome.

So get one, don't get one. On this hand I have John at phearable.net not to get a ECU and Kenji211.com saying get one.

Who shall I believe?

I don't care if I get any performance gain, I just want to run like it is now with my P2P ECU with no problems.

what are you using to tune with ? I have a map for my turbo Y8 that I will send to you, all I ask is to post your out come with my map.I am sending out my Y8 maps on pgmfi,uberber,evans tuning web sites. I love my Y8 and all the people with the y8 motor cant get the right maps for the car. well I have tested as far as 27PSI and still going strong. If you want the map send me a E-mail to [email protected] and I will send it out to you and anyone that wants to go fast with a y8 motor.
