Chipped ECU..

[mindflux]

Hey..

My ECU has possibly been chipped, however I have no idea if it has or hasnt, my workshop tried to do a datastream but apparently they couldn't due to the fact that it has possibly been chipped.

If there anyway to find out if it has, and if its tunable or what kind of chip its running?

Thanks!

Best bet would probably be to take the panel off that covers the ecu and check for stickers on it. Most places that do chips will put a sticker on it.

Not sure on any other way, I am sure someone else will though.

if there are no stickers ..take ecu apart ..4 screws & check markings on rom (chip)...usually has aftermarket tuner written on it ... markings look different from std anyway

I decided not to pull it apart as i know ill break something..

so i gues sill just leave myself wondering..

if i did find out what chip it is, is there anythign i can option by knowing this?

Put it on the dyno? Did it come with aftermarket gear from Japan, sometimes they rechip them over their to suit mods done. It possible that you could be doing damage if the tune is aggressive, and your fuel octane doesnt comply..

Hrmm.. i dont think its doing damage, shit now you have me paranoid ..

so to see if its doing damage, i should run it on a dyno?

is that what your sayin?

usally they are tuned quite rich in general in japan for different fuel...could be running lean or rich...it could be chipped it could not getting a simple dyno run is always a good idea with stuff that hasent been tuned for our fuel etc if it is indeed chipped.

sorry mindflux,

does your car run a bit harder that others with similar mods? What makes you think its chipped? I found out the hard way and ended up spendin lotsa $ for new engine.... One dyno run will give ya piece of mind, n let you know you have good a/f ratios.....

Hmm.. Now im paranoid, lol

What makes me think its chipped? .. well the story goes like this..

I asked to get a data stream done on my R32 by my current workshop/mechanic.

My workshop informed me that they could not do a datastream , because yje ECU was a nissan ECU, however its not an R32 ECU.

Upon further inspection, I found out its a stock standard R32 ECU.

when speaking to my workshop a few weeks later, and he informs me that the Datastream didnt work, possibly because the ECU may have been chipped in japan.
