Get an obd2a to obd1 ecu conversion harness. P08 or p28 ecu. Convert the dizzy to obd2 or get a conversion jumper harness for the dizzy.

 

originally my 94 civic with d15b7 used a p06. If In need I still have it and selling.

 

If you get a P28 ecu you may need to chip it with P08 maps to get it to run 100%, P28 will let you run a 4 wire O2, P08 uses 1 wire O2 but is the proper ECU for this engine. You will need the TD42U dizy from a 92-95 VTEC, I'm doing the same swap as you as I type and just found that is the dizy you need.

 

Will the d15 run that much better with the p08 maps than with the stock p28 maps. I have a d15b in my 96 ex and I am debating chipping my p28 for the
p08 maps but not sure if it is worth it or not.

 

Try it with the stock P28 and see how it runs, if its too rich or just doesn't feel right get the diy chipping kit from phearable.com, its only $40.

 

Yeah i'm driving it now and it runs good. I was just wondering if it would make that much of a difference with the p08 maps to justify the cost of chipping. Also doesn't the vtec come on at a different RPM in the p28 maps vs. the p08 maps.

 

Did u get the d15b with the two vtec sylenoids?? Cuz if so ull have to run two vtec wires into a p08 for both sylenoids to pop!\
and if u chip it ull b in heaven!!! 2 vtecss!!! Doesnt get any better

 

WTF are you babbling about? There are two different D15b motors. There is the OBD1 version which used a P08 and there's the Vtec-e version you are talking about which is OBD2 and would use a P2? ECU. You do not want the OBD2 version for normal performance use. Since Vtec-e works completely different, you also would not want to run it off a P08 or a straight P28. The correct answer is OBD1 D15b, Obd2a-OBD1 conversion, P08 or Chipped P28, and dizzy jumper as previously noted.

 

2 VTECss yo!

We need a Pimp yo Ride poster here. "we heard you like VTEC so we put VTEC in yo VTEC so you can VTEC while you are already VTECing"

 

Jdm obd2 d15b 3 stage vtec has two vtec solenoids and u do have to run a separate wire into ur ecu. It is the combination of the sohc vtec and sohc vtec-e...meaning u can be fuel efficcient at low rpm's or u can beast mode at high rpm's. It is a real nice engine. Since ur car is already an obd2, i recommend u to look for this engine. U will have to do some secondary vtec wiring and also might have to swap oil pumps b'c of the crank sensor.
