Mines tuned ecu/ need help with what kinda of tune its for.

[TibDrifter]

Hey zilvia I need some help. i got a mines tuned ecu for my s14 sr20det about 4 years ago. i had one hell of a time with it, first time i started my car it was running rich and got 10mpg, haha flame balls.
anyways i found out that it runs very well with a z32 mass, and the speed limiter is cut, and it like boost (no knock or ping when im boosting) my questing to you guys is that how can i contact mines to find out what that is tuned for.

You dont, even they wont know whats in it unless they get the chip. You're best bet is getting a new chip and a new tune.

PS: I'd be very very wary of running that ECU on CA 91 octane piss water. Japanese gas has a way higher octane (range of 94-101) so if its tuned for that, you can get your ass itll ping like a mug on 91 octane. Doesnt take much to get rod knocks on SRs.

If it is a JDM ecu, i.e. it came out of a front clip it is probably tuned for 98 octane at least. This means if you are using US Gas you are probably putting A LOT of stress on your pistons and engine because you will be experiencing additional KNOCK which you should not have.

This is why the Mines and Central 20 ECU equipt cars usually blow their piston rings and ring lands like crazy. WAY too much timing and way too lean of maps again because they are meant for Japanese gas of at least 98 octane.

Some of them will actually come with stickers with warnings in Kanji saying not to use less than 98 or 100 octane. A lot of them have this REMOVED because shops want to sell the ecus for a profit even though they should not be used on American cars.

I would suggest selling it to someone who is planning on running race gas in their car on boost and buy a PFC used or something that will allow you to get it custom tailored to your setup

That's cool except Europe/Japan use a different octane rating system than the US. 98 octane over there is more or less 93 octane in our rating system.

Yeah well either way the knock box we use doesnt lie

The mines ECU tuned cars ping all over the place with anything more than 7 psi of boost

You will also notice the turbo manifold turn RED hot after a couple of consecutive runs due to the wild timing maps in most of those suckers.

I wouldnt run anything on my car now that I didnt know what the map was scaled or formatted for, at least not after all the bottom ends I have blown trying to do the tuned rom(mines ecu) + AFC setups in the past

[chibo]

Fair enough, facts don't lie. I just wanted to dispel the myth that the US gets shit gas rating wise compared to every where else.

[ManoNegra]

Running an ECU that's been tuned for god knows what
just because the sticker says Mines on it.
Priceless.

[lazysk8er2]

you wont find out whats on it unless someone has told you before hand...but a retune should be considered

just learn japanese
Mine's (http://www.mines-wave.com/)

[steve shadows]

haha there ya go!

[cotbu]

Dump the ROM! Send it to a competent tuner.

[bardabe]

if you are curious about what the ROM looks like let me know I can hook it up to my computer and Download the BIN File, we can compare it to the stock BIN, so you can see exactly what it's tuned for.

man thats sucks form what i have been hearing from you guys. The funny thing is i have been having this ecu for about 4+ years on my SR, crazzy ha. I havent blown any piston rings or holes in my block but i just wana be safe than sorry. The set up i have is z32 mass, 550cc,gt2871r boosting at 1bar during the whole 4years. all of those set up are educated guess. I have heard a lot about the jdm ecu being tune on higer octane then the states here, so i guess ill just have this ecu as a backup for higher octane days.
BTW bardabe how do you check for the bin file, im located in the bay area so i guess i can contact u when im in LA area.

[bardabe]

I have to wire up your Consult port, %99.9 of the people that do Sr swaps don't wire up consult. then i have to hookup my consult cable, and load it on to my laptop. open it up and show you.

You might just be lucky, as I said MOST are tuned for much higher octane, but some are not, so it's luck of the draw.

I personally wouldnt use anything on my personal car unless I knew what the cells were set to for timing AT LEAST and what he AFR and ext temps are OR unless it was tuned stateside by an experienced US tuner
