can i use a pr4 in my dx wit mpfi swap on a sohc

 

yeah bcuz i had a pr4 in my sohc

 

as long as its a obd0 mpfi ecu you can use it.

 

well i'm giting some codes 14 4 and 9 wtf

 

is your car an 88?

 

no a 91 hatch

 

did you look up the codes? i dont know them off the top of my head. list them and ill try to help more.

 

i'm giting 49 and 14


1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
71 random misfire cylinder 1
72 random misfire cylinder 2

Yeah, you *can* use it, but it's the wrong ECU so it's going to cause problems . . . thus you *shouldn't.*

If you're running a pre-OBD MPFI SOHC non-VTEC D15 or D16, you should be running a PM6.

Codes 4 and 9 usually indicate a bad distributor base.

 

well i got a d15 out of a del sol

So why are you running it with a PR4?

 

its the only ecu i could het a hold of

 

you should be gravy just troubleshoot codes

 

i had a pr4 in my 91 rex with a d16y7 and it threw codes but ran like a rape ape

 

well mine falls on its face
