My ecu has been modified by a Japanese company called Auto Aqu(www.autoaqu.com). I'm looking for any info I can on it. I've tried contacting the company but googles best Japanese doesn't seem up to the job.

The ecu to me(I know very little about that end) looks unmodified bar stickers and tidily sliced seals... However the car vtec at 4750 and limits at 8800...

Any and all information and help is GREATLY appreciated. Thanks you!!!

 

the MCU has been replaced, can tell by no coating on it and the rosin traces around it.
other than that, it's really difficult to tell.

 

excure my ignorance in all things electronic... Which???

 

MCU = OKI IC in the last pic

 

first step in the right direction. Haven't been able to get any info here(Ireland). Much appreciated Relic. Thank you!

 

oh wow, an oki 66p. those chips are rare, and expensive. thats a one time programable chip, looks like these guys have a programer and a supply of those things. i wish i could get my hands on one.
show that thing off at http://www.pgmfi.org in the OBD2 section. i am sure that more input can be garnered there

 

I had that ECU about 6 years ago.....great for mild modifications. rev limiter raised a bit and the fuel and timing changed a bit. I think the VTEC point was brought down to engage 500rpms quicker
