Mines Vx-rom

[pauly]

ive run my car with a mines ecu for 18 months with no problems at all, infact its been the best thing i have bought for my legnum you will need a boost controller though and run on super unleaded.i think theres someone else on here who has one in new zealand and his car is the fastest over 1/4 mile on standard turbos. there is also a video on you tube with a galant vr4 with a mines and that does 0 160kph in around 11 seconds not many vr4 will get near that without one its a top piece of kit

i have the HDi boost controller...and as far as fuel goes, the best fuel we get here in Australia is 98 octane, i was tuned to 100, lucky because in Japan they have up to 110 octane..

I've also got a Mine's ECU and although I dont drive on max boost all the time I've always serviced it regularly and always used high octane fuel. After about 6 years - still zero problems with it. You might get slightly better power with a custom tune specific to your setup but Im still getting great performance considering all the kms on the engine/ turbos so Id still highly recommend this as a plug and play option.

Well, i can just say that engignes can take lots of knock without dying then! Since i can recall that mines rom gave us something like 15-20 knock counts. We must have durable engines then To remind you all, it has +3 on ignition from load 140 upwards.

probably just your car mate mine doesnt knock and i have been monitoring it for over 12 months

What with?

my original comment was meant a word of warning to what looked like a new member, as it turns out he is quite happy with how his car runs. which is nice.

i just would not have wanted him to damage his engine, with knock.
i have nothing against mines ecu it sound like they are setup quite well.
To be able to run high boost and not knock with only the ecu and boost control being upgraded. that is a good result.

[Davezj]

just out of interest is this Mines ecu a complete replacement ecu or just a reflash of you original ECU with a different rom file?

[wintertidenz]

Reflash of the original ECU.

[CANDEE]

I though that they were a daughter board over the top of the factory chip? I think this was for both facelift and pre..

[wintertidenz]

No, these were reflashes from what I've read up about - there's no spot for a daughterboard.

The 6 and 7th gens have the daughterboard IIRC.

[CANDEE]

Tinteresting, wonder if i can unseal and reseal a couple that are hiding....

I have personally tuned many vr4:s here in Finland. And yes a vr4 cannot take that much advance without knock. Or then your fuel is just much better So it isnt just my car, all the cars ive seen here are very sensitive to that and the result is around 320bhp with everything right.

Anyone got a copy of the MINES ROM so we can see exactly how far they pushed / abused it?

That said, they must have put in some serious R&D with desoldering of the CPU to reprogram it (presuming they didn't use the 7201 with external flash), so they must have known what they were doing. I'm always up for learning so if anyone has a copy of one of their ROMs I'd be curious to see what they did.

here we go...

[foxdie]

Fantastic, thanks Alex, given you some rep

[foxdie]

i have the "mines" ECU , i couldn't happier, what a score....this is what they sent me back when i sent in the barcode... i used google translate for japanese so they would respond, i tryed a few emails in english with no repsonse..


Fuel mapping and ignition timing optimized.
Speed limiter cut
Rev limit +300 from stock
Boost control is also set in the ECU at 16psi

Also be advised that VX-ROMs are set to run on 100 Ron octane rated fuel.

Okay to clarify;

* Speed limiter is indeed removed (or rather its set to 510 KPH, I'd be terrified if the car went that fast, haha!)
* Runs slightly leaner above load 140 and engine speed above 5000 RPM
* Generally runs 4~5 degrees more timing across the board for better economy, 5-6 in torque areas, around 3 in the power areas
* Rev limiter of 7653 RPM vs the stock 7296 RPM (so loosely an extra 350 RPM)
* Boost (fuel) cut load limiter set to 220% up from the stock 170-180% (so it's upped from roughly the 0.9-1.0 bar region to roughly 1.2-1.3 bar region)
* Target engine load of 103% across the board vs the stock sliding 89%-110%-80% default scale
* Target wastegate duty cycle of 82.5% across the board vs the stock 49%-34%-67%-30% scale
* Slightly more tolerant of knocking

This reaffirms what MINES have told pauly, it'll be slightly better on economy for cruising, boost will be raised to around the 1.0-1.1 bar region with a fair bit more lower down torque and a reasonable power increase probably in the region of about 310 HP. It's definitely mapped for higher octane fuel, that's for sure and will knock like a bitch on our 95 RON, 98 RON is an absolute minimum. I'd be very worried running that tune on an ageing stock fuel pump too, it's tempting fate.

[peter thomson]

I don't think all mines ecu's will be the same as I know of one with a limit above 1.2

[lateshow]

You can actually easily drive with a load limit of 220 cause you rarely get over 220 over a period of one second (thats when it really does the fuelcut) The boost may spike a bit but then go back to around 1 bar.

i can't unzip the rom file it says access denied
do i need a password to unzip it.


sorry my fault i tried extractive it directly to my ecuflash directory which yo can't do.

all sorted now
