Well i asked this question elsewhere but it was a bit vague so here is the padded out version of events.
Recently i took a mate out in my SiR2 and asked he asked why my vtec came in at around 6000 (high even for that car) and also why did it rev to 8600 rather than 8250. In reply to this i told him i had no idea so we went inside and googled 'honda P30 ecu' had a look at some pics and went to have a look at mine,which needless to say was different to the pics although it still had all the relevant information on it sayin P30 and all th rest. So i was wondering if the JDM ecu was different also would someone please put a pic up of a stock p30 so i can be sure mine aint stock?

 

if your ECU says p30 then it's a p30. if the revs and vtec engagement are off, you might have a chipped ecu. not sure if JDM is different.
