Server is down can't search! Does anyone know the specs for a obd-o pr3 ecu? I have one in my car right now and its only letting me rev to 6500 rpm...Anyone know why?

 

fuel cut is somewhere between 81-8300

 

check your codes

i could be wasting your time here, but check the ecu to be SURE it's a pr3.

 

yes it is a pr3. the vtec does kick in. Sometimes when I am just cruising at around 80mph. I get a code 9. would that have anything to do with it? I never get that code if I use my pm6.

 

Make sure it is not an ECU for an Automatic:

Remove the top cover and it should say "MT"..
If it says AT, that is your problem..

******* jdm distributors..

jesus christ they do this **** all the time.

i think they're doing it on purpose sometimes.

 

Vtec is at 4800, rev limit at 8200.

If you can only get 6500, then you're throwing a code. Probably one having to do with vtec.

i learned something here today, and i thank you

 

auto to manual conversion.
this is all u need to do no chipping necessary.

 

woah woah, whats happening in this picture, all i see is a board, and red, blue circles and arrows, doesnt really tell me what to do :S:S:S

 

sorry about that, i mess with ecu's all day.

this area is underneath that center bar on the ecu, use the really long chip as a landmark.

u gotta move the resistor at r68 to r67.

 

i just checked mine and it doesnt have a MT or an AT marked on it......???

 

thats odd, take a look where the resistors are. that will be a dead giveaway

 

So are the fuel maps the same on the ecu that was designed for the automatic?

I have read that there was some difference between the two..

 

yes, maps different, redline different, and it's got weak cams.

not sure if the vtec point is different?

there was a difference with the valve springs also, auto only has single, but I think that's only with obd1?

 

Hi , do you have any pictures of this modification? Thank you!! June , 20th 2019
