hey guys,

just want to know whether anyone has had expirience with these plug in retuned ecu's from japan? i got my hands on one from a mate cause he thought i might want it....LOL (why not)...

just wondering....has anyone used one? results? doesnt matter what rb motor....but i just wanna see if they r really a sham..coz atm i got std ecu with fuel cut defender running the mods i got listed below.

is there a website to check the computer ID number or watever u call it? cheers. i got another ecu planned for my 32....but maybe this could be good.

my mods:

full 3 inch X-force exhaust

hybrid frount cooler

highflow r25 turbo

fuel pressure reg

what gains r there from these ecu's? sorry guys im new to the ecu side of cars.

cheers,

daniel

The only gain is a sketchy tune state.

I say this because the tune isnt for our fuel, and you have no idea what mods the ECU was tuned for to begin with.

Japs ECU's like that unless re-tuned here (sometimes impossible), really are mostly useless unfortunately, and can cause far more harm than good to your motor.

i had one, put it in my 32, was no different then the standard one at first, but after a couple of weeks using it i started to notice i had slightly better fuel economy and no speed limit and rev limit lol.

but as r31nismoid said, they can do more harm then good, because you dont know what it was originally tuned for.

mines been running in my car now for over 1yr, only cause i havnt gotten around to takeing it out lol.

i have had good success with Mines ECU's

But like what most pple say they are not tuned for your fuel.

Most ones iv got from Japan have been for stock injectors and are just a general power up like what your would get for your Civic from "Chip Torque".

But with that said most Mines ecu's i have used have given better ecnomy and a little bit harder on bout 14psi with only basic mods to an rb20.

I have one mines ecu for a a31 that came with GTR injectors,GTR Pump etc etc and it was a diaster, on 8psi the thing would ping its ass off.

Although tuned roms are still popular in Japan, i would only buy one hear if i new what it was tuned for.

Blitz access expreriance is only of an sr20det 180sx. Thing went really well for what it was.

Cooler, stock turbs and had seemed to go realyl well with the ecu in it.

Then one day it just died. :wub:

Throw the ecu in, and just take it easy, listen for pinging!

Make sure you have a good tank of premium and just take it easy until you know it will run the car fine.

Really you can plug it in, get it on a dyno and see what happens.

You'll need a fuel pump first, i wouldnt even go near a dyno without one

Personally i think your wasting the dyno money, as the ECU isnt going to be anywhere near decent IMO.

oh ragex! yes it does have a blitz sticker on it....and two access stickers over the sides, plus an ecu number sticker on it....that help?

ok i have an essential tuned rom, i didnt use it cuz i had so many mods on my car but anyway, OPEN it up, and look in side what you are looking for is 2 kinds of these computers

one has a say 1 inch square chip on the board some times they have a glue on them it has tiny little legs all sides

THE other has a retangle chip also known as a EPROM it has little legs only on the long sides.

if u have the retangle one, you can actualy retune that computer, by your self if your confident OR take it to a few places i can recomend

P.s the square one can be tuned but no one will do them sorry....

i have a square one :laugh:

ragex,

would u mind giving me PM just in case it is the rectangle one.

cheers

Thats even sillier! You wont know what the AFR's look like.

If you hear it pining, then its way too bad of a tune.

If you wanna spend $80 and give it a go, no worries :)

It's silly to judge by what you hear too, because pinging and knocking is most often inaudible to humans in the first place.

It's only serious knocking that you hear. Sometimes it's already weakened the pistons by that time.

    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
