For past couple of weeks I have been having some problems with my car. At first I thought it might be the uberdata chip I was using so I switched back to hondata to test and see. Problem still seems to be happening. Every couple of days I go in to start my car and as soon as I turn the car on the cel comes on and the car is very hard to start sometimes it won't even start. There is no code that is being thrown the cel just comes on and stays on no blinks nothing. If the car does start it idle's very very rough so rough that I can not drive. When this happens I disconnect the ecu for about 15 secs plug it back in and start the car and the car starts just fine. There are also times I can be driving and the car will just cut off and once again I have to disconnect the ecu for about 15 secs and then plug it back in for it to start. I cannot figure out what the problem is unless it is the ecu itself though I figured if it was it would never work. Can anyone help me with this that might have had this problem before.

Here is my set up
B18c5 Stock
Full-Race t3/t67 turbo
Custom manifold, dp
Rc 550 Injectors
Boomslang obd2-obd1 harness
Resistor box
p28 ecu running uberdata and hondata depending which one is working at the time

 

a solid CEL would indicate a bad ecu. My guess after your past weekend at bristol with some good hard launches, you may have jared the ecu enough to mildly break on of the soldier connections by the socket.

are you using a ZIF socket in the ecu? like the little blue one? I've had one of them fail on me before, maybe try removing it.

 

try another main relay and check the ground at the thermostat housing..

 

rotate the tires and check the oil.then rotate them again.


just kidding.check your ecu and grounds.i had the same problem and it was the ecu.


harv

 

Yeah I am using a zif socket... I checked it and it looked fine but I still went ahead and put the standard black socket in and we will see how that works. I will make sure the main relay is also grounded well. ALso I didn't go to bristal.

 

hrmm, i guess i saw b18c5 and assumed you were the white ITR in the pics.. either way try the ZIF, strange **** happens from time to time.

 

any othe conclusions
