ive had this P05 ecu for a while and found a buyer thinking it was stock. He installed it on his civic and it did not start. He said it gave a CEL for vtec im guessing code 21 or 22. I tried the ecu on my gsr and it started up so i know it works. He told me its probably modified, possibly converted to a p28?

i took a few pics so maybe someone can tell me what it is?

 

It has an SST chip in it so yes it has been modified but with what map?

 

Yes, it's been converted to be VTEC capable.

 

Thanks guys. So would this be like a p28?

can u tell me what to sell it as? And about how much it is worth?

 

A P28 has the O2 Heater output, a P05 does not. Most people don't think about this when converting to VTEC. Selling it as a P28 equivalent is not an accurate statement because of this.

OBD1 VTEC Converted ECU.

 

Ok thanks

can this ecu still be used with crome, hondata, etc?

Sorry im a noob with tuning

 

Yes.
