What can you tell me about this ECU ??

 

according to Hondata's website it is a :
"P73 : 96-00 OBD-2 Integra Type-R (JDM & USDM)"

look here for more info:

Some guy tries to sell this ECU on ebay as a JDM ECU to upgrade from EDM ECU (also P73).

I don`t see the point here.

What is the difference between A 96-00 JDM&USDM ECU to a 2000 EDM ECU ??? JDM b18c and b18c6 are the same, only the header is smaller.

The JDM Ecu have a different MAP for use with the RON 100 Octane.
I have a modified stock ECU with a Mugen XH4 MAP, work wery well but no HP gain. Better on the track because you'r always in vtec.

If you want call or email my frien HRED (www.HRED.net), he is able to modify the EUDM ECU, he makes mine very well.
390€ + shipping for the mods.
It 's like a real Mugen XH4 ECU (discontinued at Mugen.co)

 

But if this ECU is a JDM & USDM, how can be optimized for 100RON ???? There is no such fuel in the states....

there are different flavors of the P73 ecu - the JDM one is different than the USDM...

Hondata is incorrect, this is actually the 96-01 ITR ECU...

 

Ah, okay....

So could it be there are some gains possible changing from P73 EDM to P73 JDM ( I have a 96 b18c-R JDM spec engine in the car and access to 100 ROZ fuel) ?

 

no none at all i would think, you would gain a 120mph speed limiter and thats about it!

 

yeah.. that`s what I think too......

I stay with my Kenji ECU for track action and stock EDM through the cold season.. Thanks to all who posted

 

The BIG difference is the immobilizer...
