NINE TRE

sup peeps,

ok, before i begin... i have searched and read thru the archives of ht in this forum, and i still have unanswered questions to ask.

here's my situation:

engine: b18c5
harness: 98 si (obd2) w conv. harness (obd2-obd1)
ecu: p28 chipped
chassis: ek (97 hatch)

i got the swap in after many days and nights due to some unexpected interferences...
i got the car to start, and the problem starts from here...

1. im getting a CEL (code 6) - i think this is ECT (water temp sensor) --> how do i fix this?

2. the car "chokes" / "boggs" each gear when i rev it to 2500+
i have no power, and it almost seems like the car was gonna stall within those revs.

-so i checked the fuel pressure, and it read 80+psi (according to the b&m fp guage my friend had)

-im using a b&m fpr, and even when i lowered the adjustment, it still stayed the same reading: in fact, i swapped my oem fpr, and it still stayed at 80+psi. (what psi should it be anyway?)

- i know this is super rich, and this may be the main reason why my car is running like $hit with no power. but how am i supposed to be sure? is there a method to check or adjust (lower) the fuel pressure without purchasing a different fpr? could it be my stock fuel pump? filter? please help.... this is my daily, and it's been outa commission for a while now,,,

thanks in advance!

update: i bought a new fuel filter and changed it, but still no change!

i don't remember for sure but i'm thinking its supposed to be 40ish

you should resolve the issue before you drive it much.. running that rich probably isnt good..

Make sure the tps and map plugs are not switched. They are the same plug and can get mixed up pretty easy.

Stock fuel pressure is 42psi I believe...

Check out this link for a diag sheet for code 6...

change the fuel pressure and try swappin in a new or a good known fuel pump. the water temp sensor is located right underneath the distributor, its the middle plug with one wire comin out. try replacin that to c if it clears the cel.

That is just the water temp sensor for the gauge in the dash, the one that the ECU reads from is the 2 pin connector off the thermostat housing (at least on my CRX and my EG) the EK's may have two, I can't remember for sure.

doh, ur right. its late, im tired. yes what he said, try replacin that piece. i switch mines out to a spoon sports one. works great. a stock one should be relatively cheap.

ok... i will give it a shot in the morning for the ECT code..

but as far as fuel pressure? damn this is frustrating...

It worked well for me. But I wasn't at 80 psi either, i was around 60. if it doesn't lower it enough, drill a larger hole. Just be careful not to drill it too large. The size bit they recommended worked perfectly for me.
