Guys just to clear it up the Mines ECU that I bought for $150 !!! on ebay was sourced by japan dyno they trade through Ebay in the US but do not have a presence in europe yet. However my company has US employees so I buy, ship it to my buddy's houses and they mule it over when they come to work. Anyways japan dyno get to pour over breaking cars in japan, take off all the trick bits and sell them on, so for example right now they have an HKS piggyback fuel computer for sale etc. You can mail them your target spec and they let you know when they have bits for you, its a wait but they come up with the goods. They sell everything from salvaged turbo timers to, get this, a full Mines / JUN 300zx Engine :bow: just depends what they find. They tell you the car it came of the mileage used for (if documented) and everything I have had has been 100% as described. Remember the Japanese are about 1000% more quality obsessed than us and to provide something that was not as described would be dishonourable...........

I bought a Mines :bow: 'Mild tune' ECU z32 TTAuto spec. It is therefore mapped for the following:- 97ron fuel, Hi-flow Induction kit, Uprated boost, Aftermarket exhaust, and interestingly Mines 'recommends' upgraded intercoolers with this ECU. (I have stillen intercoolers). I do not know what the power-up is with this ECU need to do a dyno run but I heard +70hp. All I know is torque is massively up. So yes the chip is burnt in to the correct map for this spec and I have a sweet little Mines logo and tamper seal on the ECU unit. Downside is of course that yes If I go above this spec I would have to re-map but hey at $150-200 I could just ask em to look out for the next spec up. Does anyone have any mines dyno prints ?

Why would a Jap ECU be mapped for 97ron fuel? and 70 gee gees from a chip?? Dave

Because being a highly regarded tuning house Mines build safety factors into their work. i.e. Incase of bad fuel / bad human filling the tank in japan. Although Jap fuel is up to 100RON they too like us have crappy supermarket type fuel probs. So............ Mines map with that safety and their reputation in mind. Imagine the press "I fitted a Mines ECU and holed a piston!"

It makes the results they get all the more impressive. I only learned this through the guys at japan dyno who warned me away from some smaller name tuners' upgrade chips / ECu's saying that some of the smaller name tuning houses in japan push the safety envelope to get the figures to compete with the masters. They would almost certainly not work with your UK fuel they said. When they supplied the ECU they knew about optimax and said "use that or BP ultimate and it will be fine".

:x:

Sorry to keep jumping your posts, don't mean any offence. Just seems a little odd to me. Don't the japs have 102ron? and I can't see them mapping a top quality chip for 97ron, its like us mapping for 95ron or less. People wouldn't put such low quality fuel in unless they really had no choice. I take it you are selling these?

I only heard '70hp' from a mines ECU from an anecdotal conversation thats why it would be cool to know what the reality is for each of their stages from mild to wild. There are probably dyno-charts somewhere on a dot JP site.

 

I have no way of guessing what the result was but I could really really feel the difference way more than say the intake, or 10% boost up with the boost controller. Maybe the listers can have a sweepstakes on its actual figures and I'll give a 6 pack to the winner at the next dyno day.........Start the (educated)guesses guys

No I am not selling anything, I was just pointing out that this stuff is easily available and reachable by us guys in rip-off UK.

 

It simply amazes me that in these global times people will pay say: £1,800+ for a Tein EDFC set-up that is less than half that price in the US..........

 

Or pass up the chance of 2nd hand performance parts and spend silly money in UK stores / mail-order

Think you're being taken for a ride all the same mate.No offence.

Just to clear it up as well US Ron is not the same as Euro Ron neither is Jap Ron. I know that is as confusing as shit but Ron is like gallon.........perhaps Oilman can help out

The RON difference would not make any difference to power anyway, it is the fuels resistance to knocking/detonation. Therefore using OTHER factors (turbos,etc) you can run higher power before the heat increase causes detonation.

USA use PON which is the average of RON (research octane number) and MON (motor octane number). Both are tests to do with with det resistance at certain inlet air,engine temps and rpm.

Amen that is why they would map for the lowest grade fuel ever likely to be put in the car even in an 'accident' to prevent detonation probs from ever occuring. Japanese engineers call this Poka Yoke (translates as human proofing - I was trained by kawasaki so you learn this kind of shit). Idiot proofing their work so it is impossible to ever have their 'art' and or reputation screwed it up.

 

I have no idea what the power is from their 'mild tune ECU' but would sure like to see some dyno charts

Power from Chip alone would be very mininal. The power increase comes from the Raised boost.

Sorry mate but not buying your angle! Idiots are people running too high boost for there engine and car setup. There is no 'idiot profing' for this , they'll melt there pistons regardless of mines mapping philosophy. Mines are not going to waste there time mapping to 97ron for reasons such as this, complete waste of time and performance.

Yeah I would have thought that too but my boost guage (in-dash) and on my boost controller (not activated) runs to about 13.5psi with the ECU but it feels way way better than when I just had the boost controller winding boost up to 13.5. So.........I figured that the ECU has just got a better fuelling map designed to get the most out of the intake / exhaust / intercooler combination that it was originally mapped for.

From Mines's site...........some charming translation

 

Mine's VX-ROM Performance ECU

Mine's VX-ROM is best seller in the aftermarket ECU products in Japan, and Mine's programmed ECU to suit fuel octane of 98 RON.

Mine's VX-ROM ECU modules always offer a considerable safety margin in programming, where engine durability is considered an important factor.

Furthermore, immobilizer function will still work with Mine's VX-ROM for the cars with immobilizer.

By changing the specification of the engine control unit(ECU), which is the engine's brain, the potential capability of performance cars is extracted to the maximum extent.

(this procedure includes fuelling and ignition timing re-maps as well as various limiter setting alterations.)

Basic VX-ROM is applicable from standard cars to stage one tuned cars with uprated inductions, exhausts and boost controllers.

Programming can be continuously updated as more tuning is carried out. (for the first owner of the ECU and subject to upgrade fee.)Please contact us for availability on specific vehicles before placing an order because some models requires matching of ECU part number and chassis number.

Don't know why you're giving this guy a hard time?!

Most of what he's saying is spot on.

 

70bhp is not unrealistic if you have already done the exhaust, intake and maybe intercoolers as Mines or any other ECU tuner would expect!

The chip is in there for one reason - so you can run more boost.

 

ALL the well known tuners map their cars to normal road fuel, not the best you can get in that country - why not have your can mapped for race fuel if you want the maximum power?

If we all had our cars mapped to the limit for Optimax then we'd fook our engines when we couldn't find a Shell station.

my swb tt manual slicktop has a mines ecu fitted in japan on it .I found it the other week i didnt know it was fitted nor did the importers i brought it from .I run 99 ron tesco super all the time no problem.Ive been told these ecus are one of the best u can get for a Z. More are fitted in japan than any other atfer market ecu .Also in japan these ecus are cheap options to be used as a speed de limeter only 112 mph.Mine only had cat back exhaust only standard air box and standard boost.

The Mines is generally regarded as a More aggressive ECU, with advanced timing compared to the safer JWT option.

 

There may however be differnt varients of the Mines.

From what I've been reading with regard to general tuning and tuning houses I'd have to agree. Remember the mines ECU's are very popular in Japan because cars using them don't melt.

Fair one if its all spot on, just seemed a little odd last night. Didn't mean any offence mines, just got the impression you were selling them or something. I'll wind my neck in.

There may however be differnt varients of the Mines.

 

There are. One of the ECU's I had came with a larger ROM and control hardware containing 3 maps which were switcheable with a button by the driver.

I copied the maps off to seperate standard ROMs but never tried them as I'm running 555's now.

ive got a mines ecu on ebay for sale

Not Quite

 

MINES is one of the only roms/chips you can run which actually do make a difference without increasing the boost this is due to timing advances at certain load sites along with leaning out the mixture both will give more power at the same boost level , MINES is a fantastic ECU I ran one for 18 months you just haveto be very careful with the amount of boost you run and as always listen out for dett

What was the max boost you ran? (just curious ;) not fitted yet)

no two cars are the same so what i ran may not be safe for you to run there were also many other factors like weather etc i used to run 12psi in warm hot weather but in cold weather i could run as high as 16psi due to the denser air

 

because of the leaning out of the fuel to gain extra power you have to be extra careful some 300's handle this no problem others will struggle no two cars are the same which is why the off the shelf JWT option is very safe, basic but safe
