i just put a jdm h22 in my integra....has cams,i/h/e/pulleys/flywheel/intake mani....we have a usdm gsr obd2 ecu in there right now.....the motor is obd1, shell is obd2, ecu is obd2.....after 4 grand the car gets NO power it feels like im in 5th gear when im realy in 1st.....its throwing....

secondary o2 sensor......
iacv........
knock sensor.......
crank fluxuation sensor....... what does this mean???
Fuel Tank Pressure Sensor Circuit Low Input........ what does this mean??

does my car feel like its always in 5th gear because of these codes...or is there something more seriously wrong....thank you

please help me on how to fix the crank fluxation code and fuel tank pressure codes, thank you everybody!!!!!

 

i know i should change the ecu....but this setup ran AMAZING in my friends hatch...it was his motor and he ran a usdm gsr ecu and it ran amazing....

 

If its the same set up with same dizzy and ecu and wiring and it ran in his car, check all the grounds, a bad ground on the engine harness can make a car throw codes like crazy, just an idea

 

he used an obd1 ecu, you are using an obd1 motor and obd2 ecu.......

Thats your problem

 

obd1 has no crank sensor(not integra)
you only have one o2 on obd1(on integra)
im not sure about the knock sensor thing...

Basicaly your ecu is looking for non existent, or incorrect ****.

Get the right ecu and youll be fine.

 

oh didn't even see that ecu

 

ur right man.....

so what is an obd1 h22 ecu...a p13?

 

or since i have cams, i/h/e, clutch, pulley , flywheel, intake mani that i should i get a diff ecu?

skunk2 stage 1 cams btw

why would you get a different ecu? Just get the ecu for the motor and see how it runs. Maybe find a buddy or someone you know with a prelude and try out their ecu.

 

just plugged in the only obd1 thing i had.....not sure if its s100 or s200 hondata...but its a p28 thats currently tuned for a jdm itr motor.....car still runs like *******...slow as ****.....and bogs a lot.....but i only have a cel for iacv....im not beating on it at all....getting it tuned next weekend in long island at NRG-TECH

 

when i get past 4500 rpms the car is slow as **** and has like no acceleration....tiny bit of misfiring too.......is this bcuz of the ecu?

 

well the motor is obd1 and everything is obd2 so thats why its fucked up

you need to convert the motor to run with obd2 or convert the car to run obd1

yup yup yup!...remeber obd2 has a **** load of sensors

 

but would those sensors limit me to going like 50 mph?

 

yup!....if its a OBD2 ecu..trying to run obd1..then ecu not gunna see the missing sensor...so it thinks there fucked...sometimes sending too much fule or too little....and also could mess with your ignition system! which is why you can't go past 50mph

 

secondary o2 sensor......
iacv........
knock sensor.......
crank fluxuation sensor....... what does this mean???
Fuel Tank Pressure Sensor Circuit Low Input........ what does this mean??

are those the codes its shooting out? if it is then those are most likely the sensors that are missing....and yes...all these contribute to a fucked up ride...i'd say get a OBD1 ecu and just get the jumpers. save you some time.

 

nah i put on my hondata ecu i had lyin around....i bought it from my friend who had it tuned for his jdm itr motor in his integra....every code went away besides iacv....code 14....the hondata ecu is obd1 with a jumper for obd2a already on it..........

so the only code i have now is iacv....but the car still runs the same about...still cant go fast at all and car picks up til about 4500 in every gear then feels like 5th gear

getting the hondata retuned for my setup on saturday at NRG TECH on long island

 

humm.....sounds like it could be a timming problem too..have you checked your timming?

 

nah i think it needs to be adjusted....cams were put in too.....u think thats another reason?

 

yo lau i pm'd u

 

PM back...

 

Im running an OBDII ecu on my OBDI motor due to theft, and it runs perfectly, but it does throw a CEL. Why not try using an ECU from the car the motor ACTUALLY came from.

 

i dont think the timing is off.....i dunno...changin plugs/oil 2moro ....anyone else on why it STIlLL runs this bad?

 

ya dig
