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 ?

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.

 

 

Spot on Dave,

 

However in the states/Canada they are now using the AKI (Anti Knock Index)

I've had to do a load of research because i'm shipping my car out to Canada and dont wont to melt anything ;) Had an interesting chat with Shell's leading development engineer ;)

 

Different octain systems

 

RON. Used in Europe and japan. Very old system developed in the first world war because aeroplanes were suffering from engine failure. They needed some regulations put in place.

 

MON. A much newer test developed on modern combustion engines in the states.

 

AKI. The latest system level developed for todays engines. Far superior to RON with far better control of quality

 

Basicaly 98 Octain (RON) in the UK is the same as 92 Octain (AKI) in the States/Canada.

The downside of all this is by the time you actually fill up with fuel your 98 ron fuel is probably more like 95-96 due to the fact it goes off , always better to use a busy petrol station as they get more regular refills so does not sit in a tank for days

Had a Mines ecu in my z, 12.5 psi, always optimax.

Never had any probs.

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.

 

Bit of a contradiction there mate. The longer, (if you like) it takes for an engine to Det, ie the better the fuel. The more boost you can run so more power. Everything else being equal etc.

What you are saying is what I was getting at though mate. That its not the higher octane fuel that gives more power itself, but the ability to run higher boost on it before it dets. All said though I'm not an authority on the subject (although I do like having the technical discussions on the forum so myself and others can learn something from the people who do know their stuff). Dave

Fair comment. :-)

Wow,

For my first post I really felt like I was being flamed for a while but it seems that people with actual facts and experience prevailed over the 'speculation' based posts and my questions / commnets were answered sensibly. I think we can summarise what we have all learned below:-

 

1) Mines ECU's are very popular for the 300zxTT in japan

2) Mines ECU's are mapped for 98RON fuel - data source, Mines's VXROM website

3) Mines suggest using Uprated intercoolers with their ECU's which corroborates earlier post about being careful re: overboosting them and also me getting 13.5 psi in normal hot day and 14-15psi on cold morning once my stillen intercoolers were fitted

4) Mines do three ECU's - 'Light tune' - Standard turbo's, Standard injectors, Boost up, Air intake, exhaust and intercoolers upgrade.

'Medium tune' as above but for larger turbo's and injectors

'Race tune' altogether different beast with three switchable maps

5) Mines ECU's are different for auto and manual

6) MinesTwinTurbo is NOT selling anything just wanting to learn.

 

For the speculators out there the chinese say that "the route to wisdom starts and ends with the words 'I do not know'........" Its ok to say that rather than post messages that should begin with the words "I think"

 

So it seems Mines ECu's are a good bet for UK owners but check the ECU spec before you buy and run Optimax type fuel from a busy garage turning its fuel stock over fast

 

I think that with the 300zx we are actually following in tuning footsteps from the main Japanese tuners and from key players in th US i.e. Jim Wolf and Steve Millen (Stillen). Everything that is to be known about tuning / upgrading these cars is probably out there already...........

 

Cheers thanks for the help and no offence taken at all.......... :smash: :smash:

Hi Mines Twin Turbo

 

Sounds like a great idea.

 

Yeah I agree about rip off Britain.... it drives me insane. 2nd hand trick parts sounds like a real good idea so long as prices are low cos Id rather spend 100% to get a good part than 20% to get rubbish..that being said Im very interested..I have just got my car so I am up for all sorts of stuff.

 

I guess if you could keep me informed of what you have ?????

 

Would you also like to know what items I need ?????

 

Well Keep in touch

Hi John I wasn't selling anything myself, I originally posted to give props to a guy called japan dyno who trades through e:bay he got me my mines 'light tune' ECU plus my autobox HKS ALC (automatic line controller). That set a load of hares runnning but anyways check out US ebay type http://www.ebay.com not .co.uk search 300zx and see the prices compared to UK. Some guys ship worldwide so it is a cheap route to get performance parts for little dough. Get them to label happy birthday and mark as gift.........

Ah I see Ive got it wrong

 

Its been a long hot day

 

Its a shame you are not going to rep. us cos someone on the list is a lot closer than someone on ebay. I dont much like the Ebay environment (just my opinion)

 

Ok

 

TTFN
