Ok here is the deal. Motor and Trans is USDM B16 out of 00 Si. Ecu is P72. What year I dunno.

Here is the deal:
While driving home from buying the car is was doing about 80 - 95 MPH. I have no idea ath RPM Range due to no tach yet. After a few minutes of a steady speed ~ 85MPH the motor felt as if it was being help back or maybe an engine brake applied. If I floored it it would "clear up" and drive fine again for a while. ALSO a couple time while in 5th the motor would drop RPM to idle and I would have to step on the clutch to bring the RPM back up. If I left it in gear and accelerated the RPM wouldnt climb from what I could hear.

I am thinking that maybe the ECU is putting the car into a "LIMP" mode? MAybe since it is for a GSR(right?) maybe it is flooding or loading up on fuel? The car also had 2 CEL Codes: 1) SPeed Sensor Malfunction 2)Knock Sensor Malfunction. It also doesnt always go into VTEC. I was told from the Speed Sensor code. I need to check to codes tomorrow to see if they come back since last I cleared them.

INFO:
96 Civic DX HB
MOTOR: USDM 00 B16 Motor and Trans
ECU: P72 GSR(I was told) Year Unknown
HARNESS: 96 Civic DX HB
---From what I can tell the only modification is 2 Wires going to the ECU.
MODS: OEM 00 Si Airbox, JDM ITR Header, Test Pipe, OEM B Pipe Axle Back Muffler

Thanks in Advance for anyone who can point me in the right direction.

u might wanna change ur ecu to a 99-00 Si ecu and check on the speed sensor and knock sensor codes...if im not mistaken u have to be as least going 20mph for ur vtec to work so if ur speedo isnt working then u wont go into vtec

 

I co-signed for the change of ECU. Change it back to a P2T (99-00 Si ECU). It should only run you 60 bucks on Honda-Tech Market place. You go to a dealer for an ECU and it'll run you 400.

Unless that P72 is chipped, it's not designed to run with a USDM B16A2. GSR open VTEC at 4.4 and butterfly at 5.5. The ECU designed for the B16 motor open Vtec at 5.6. Also, the ECU is incorrectly mixing fuel and air.

 

YOUR EVEN MORE SCREWED IF YOUR RUNNING OBD 1 P72 . GET THE P72 OBD 1 CHIPPED AND TUNED WITH CROME PRO RUN THE B16

 

p72 a01=obd 1 gsr p72 a04=obd 2 gsr.. if it was converted to run obd 1 just run a chipped p28 it'll make life easier

 

Ill check all of that out. I checked my CEL today and it is only the Knock code. The Speed Sensor code has gone away. Ill check the ECU.

PS - I am unable to post in the market place. Any reason why?

 

u cant post in the marketplace cuzz ur still a noob...u mgiht have to wait alittle longer or read the rules
