MiNES ECU?
|

Ok is there anything special about a MiNES ecu? I was told today that the ecu I got with my GT4 halfcut is not the standard item?
Or was the person that told me this incorrect?

MiNES ECU has a modified ROM from the factory unit. The modifications are usually higher boost (altered boost cut as well), elimination of speed limiter, higher rev limit. But however, they do accomodate for user requested features (say for example, WOT fuel/ignition maps to support a modified cam profiles, support larger aftermarket injectors etc., etc). There is no real way of telling what the exact modifications are (unless MiNES maintains records, you can track down the original owner or compare the factory ROM with the MiNES modified ROM).
These are very expensive units though  you could perhaps sell it and go totally programmable aftermarket. Try the mines website. It might list the default mods for the given ECU.

Mines ECU is about 1140 pounds for an ST205.
some very basic info here:
http://www.hypersr.com/electronics.html#vxrom
http://www.hypersr.com/celica_main.html
But essentially what Nishad said.....aftermarket ECU that are reprogrammed to allow more boost, higher fuel cut, no speed limiter, altered redline, but hard to know exactly what unless you can track down the original owner or Mines keep some records. There should be a serial number on the ECU, and it should be clearly labelled as a 'MINES' unit.
You can stop gloating now.

GT!!! I'd hate to see you favourites list! Is there anything on the net you haven't seen before? I take that as a no!
Hehehe
Cool1, speaking of dollars;
www.perfectrun.com.au has pricing for the MiNES VX-ROM unit you have. A whopping $3176.00 on an exchange basis or $4705.00 otherwise. This is *before* shipping + handling comes into play.
I reckon you can recover significant dollars here I don't feel so bad about your half cut missing the brake rotors/calipers anymore

Sounds like that little ECU is worth more than the whole half cut Your one lucky man(very jealous  )

But how lucky am I? Can I take the car somewhere when its finished and have the ecu tuned? Or is it just something that has to be sent away with the specifications on the engine?

The problem is nobody can tune these ECU's over here and that essentially makes them useless anywhere else but Japan. And over there is it extremely costly to tune, the Mines unit has a daughterboard which connects to the standard board and allows modification of the main functions.
Problem is if this ECU is tuned for Japanese conditions, it won't run properly here, too much ignition timing, fuel maps rich, etc.
Hope this helps.
Regards,
Michael.

This is true but so is every other ecu that comes with a import engine!

but these are optimised for ignition and fuel on japans best fuel, which we have not close to, unless we've got 105RON overnight? =]
Most people who get jap modded ECU's over here generally change them to programmable aftermarket.

No they havn't been optimised for Japans fuel! The only thing done to this ecu is the speed limiter has been removed, higher boost, higher or no boost cut and the rev limit has been upped! I rang around today and found someone who gave me a straight answer!
I also asked if it could be tuned and was told its just a matter of getting all the specs of the engine and sending them away to japan with the ecu! However it cannot be tuned realtime on a dyno!

Shane,
So you are asking Japan to tune an ECU for specs that they cant be 100% of as well as a climate that they dont have. The odds of getting it right are ridiculous! More likely to run worse than anything. The idea of a programmable comp is it can be tuned to specific air fuel ratios etc.

I'm not going to get it tuned! I was just interested in knowing more about it!
There is no real difference between this and the standard ecu apart from the things I mentioned before! So there is no resson why this ecu would run the engine(here in australia) any worse than the standard item!

You can actually get 103 RON unleaded in Australia (it comes in a drum admittedly - VP Racing Fuels), so when you have your berserk track days, swap the std ECU for the MiNES, fill up with your RON103, and enjoy the free ponies.

Cool1 I believe you are correct.
THe Mines ECU are not 'Programmable' in the sense that an australian aftermarket ECU is.
Basically they are a Factory ECU that has had some components rewritten.
There is no facility to retune them yourself to suit further mods.
However it is definetly better than a factory ECU as it does have some higher settings. It is a big advantage to have this if you plan on doing some light mods to your engine.
People blow the Japanese Fuels way out of the water. Ask any of the guys runing GT4's if they ping on PULP and I think most of them will say no (at least if they haven't highly modded the engine)

Yeah, Remedy, after you ask them if it pings, ask all the guys with factory jap imported 3sgte's if thier computer retards their timing and flings black smoke out of thier exhaust the second the computer thinks it sees another car four blocks away ping.
The MINES computer is great. Turn the boost up a bit, and instead of cutting, having to turn your car off and on again before boost goes positive, you'll make power. (and instead of merely stopping the boost cut, you actually get properly mapped fuel)
Your mapping would be at least as good as any of the other modified cars with factory computers on the list.

Yer ask any guy running the JDM 3sgte ECU and they will tell you it will ping its brains off until you retard the distributor. Hey wait thats what I had to do too to stop it pinging on our 98RON fuel. Computer can only retard so much, the problem is it pings on light throttle and top end with std 10BTDC. While it doesnt ping mid range, so it can take more timing there.

I had someone over that was looking at my halfcut and he looked at the ecu and said "heeeyyy thats not the nomal ecu, thats a mines unit"! I said its a what? Have I been ripped off? I was then told its a good thing!
