Alright y'all, I went back to the shop and traded in the P73 ECU that I was given for a P2P : 96+ OBD-2 Civic EX Coupe (37820-P2P-C12) ECU

MY QUESTION IS will this work with a 96, OBD-2, D15B 3-stage v-tec engine???

I haven't really heard of this ECU, which is why I am asking, and I understand that searching is key, that's how I got some of the info.

any help would be greatly appreciated!!!!!!!!!!!!!!!


THANKS AGAIN

You can just use the y8 ecu with the 3stage head as if were a y8, not using the vtec-e stage.

The head is the same casting as the y8 so power should be the same assuming the high rpm cam lobe is the same. I think the extra power, to make up for the 100cc less displacement, on the d15 130ps motors comes from compression, not the cam. Hope I'm wrong though.

I'm looking for a 1995 p2j ecu myself, but I'm not sure whats out there. I think this head was offered in different markets from 1995 to 2005, not sure on the different combinations with regard to manual, CVT and auto.

thanks riva,
I think you sort of see what I am trying to say....

thanks all thus far as well.....
but I would like to include the use of the 3 stages of v-tec if possible so that being said, would the P73 ECU from the integra have been a better choice to stick with since this ECU is still not exactly what I am looking for??
I was told that any 96-99 vti ECU would work?
and

I have searched quite a bit online about the P2J ECU without much reception.......

anymore help please????????

Either use a chipped gsr ecu to set the 12-16v switchover with the intake-mani-butterfly setting, or buy an rpm switch. Summit has one for $40 or so. OE ECU, the switchover is NOT solely based on rpm though, it also takes throttle position in to consideration to determine when to get out of econ mode. But yours wont do that.

With the OE Honda setup there's also a wideband processor that keeps the mixture very lean during 12v econ mode, but yours wont be able to do that either. You can set the econ switchover to like 3k rpm and just lean out your map below that. It could save you a decent amount of gas, but it probably will not come close to the mileage of the full OE Honda system. Only one way to find out though.

I would guess you could run a regular P28 chipped and tune the 12 valve mode for mileage and then tune the VTEC for high cam, and just use a rpm switch for the 12-16valve switch point. I believe the Apex-i RSM's have a rpm switch option that would work, but I will have to check on that. I have one of these 3 stage vtec engines and a 93 4dr LX, thinking of putting this engine in. The car has a 2-1 downshift grind and I have another tranny that needs to go in anyway. At $3.60/gal the 50mpg cruise and 130HP high cam are very appealing..............I'm going to tackle this and employ the work of some of the best ECU tuners around to see if it's possible to do a OBD-1 ecu with 2 vtec boards, or if not possible, at least try the above.

BTW I posted in the other post there is no OBD-1 3 stage ecu, cars in Japan are 1 year ahead of us. If you look at any car listings they have 91 EG's, 95 EK's, etc.

No Prob. When I get ready to install it I will keep everyone posted. One of my ECU tuning friends says that I can use Hondata, which has a nitrous/water injection option that triggers the NOS solenoid and allows you to add or subtract fuel as needed when it is triggered. This would work very well and could be used to trigger the first solenoid to 16V and richen the mix from the Econo-mix, but do I want to cough up for Hondata is now the question. I have the parts to try the P28 and the RPM switch so I will try that first.
