A friend of mine has an 88hf, and we just put a OBDII JDM ITR motor in it. He's got a custom-made OBD0->OBD1 harness... all the wiring is done beautifully. He's currently running it with a p72 with one of those rediculous ebay chips.

Well, with th ebay chip, it runs fine (it has a slight bog, but that's one of the reasons I convinced him to go hondata). I picked up an ITR basemap from sgt (thanks again!), but it doesn't hit vtec. The ebay chip hits vtec fine. Any thoughts at to why it might not hit vtec with the itr basemap, but hits it fine with the ebay chip?

the ebay schip may be ignoring other inputs. Are you getting any CEL's?

 

He's getting a o2 heater code, and that's it

 

Any thoughts?
