I think i just found a mines ECU

[Veilside R33]

hey all, well i'll give you the run down, for starters, i bought my R33 gtst in feb and one of the mods that was mentioned it had was a mines "chip" i thought nothing of it, didnt know what it was and just assumed it was a chip in the standard ecu.

anyway ive since been told by several people they have no idea that we could put chips in our cars, so i thought i would investigate.........

i just pulled off my passenger kick panel and this is what i found, it seems like a complete mines ECU. i dont know heaps about computers etc so i have no idea if im correct of not, so here are some pics, and hopefully you can tell me exactly what it is.

now in the bottom 2 pics you will see a black wire with a nearly full circle clip on it, (obvioulsy an earth) and to its left, a nut that it would have originally been earthed to, but it has either been taken off or woked its way loose over time. i reconnected it, but nothing has changed, there is no diff in the cars behavious/idle etc. so if it is a complete ECU is it connected? the car isnt very fast(compared to others) i thought if i had a mines ECU it would be far quicker. perhaps its not tuned at all?

if it is a complete unit, and its not connected, if i connect it, will i be able to get the car performing better/faster?

any thoughts and insights would be greatly appreciated, thanks once again guys, Andrew.

boo5t anyone?

There was a good article about japanese aftermarket computers in zoom awhile ago.

They got a red r33 with f/mount , mines , exhaust etc and dynoed - ended up with 210rwkw @ 14 or 15 psi? Stock turbo/dump pipe.

Something MD said though was the mines are generally programmed to run fairly lean - when they did the dyno runs they were running hi octane fuel - c16 I think.

Be worth checking afr's on the dyno if you are running more boost/stock intercooler as it might be getting lean.

Cheers!

of course its connected,

your car wouldn't run without it.

black wire is probably for something else

yeh they are just the factory ECU with a new chip done by MINES in them, they are not programmable.

Phat R33 has one in his car and when he bought the car it misfired under boost. few changes to plugs and gpas and it was all set.

in his case though the car runs RICH not LEAN, but then again you are talking about making 40rwkw more than him.

his car makes 173.1rwkw at 11 psi with to his knowledge kakimoto cat-back (no cat), trust pod filter and turbosmart boost controller.

nothing too special about them, probably more of a hinderance with the shit fuel we have over here as the are tuned for Jap fuel
