No, how would the computer get power ?

Ha said he can put the ECU into another R3 in the shop as it is easier that way or bench power the unit to install the file.

But if it is a RAM system and there is a battery in it ( I have not been able to find this info out) and the battery is stuffed how would it keep the tune until I get it back into my car, wish I knew more about computers :(

I guess I will find out, I sent the ECU off to Sydney. So I guess I will wait and see what happens when it comes back.

But for the hassle it causes even if it seems OK I will change it and I will go the Haltech Pro

What ECU was it, they might have a plug that will give it power that they can down load the tune, they just won't be able to check it

How did you lose the tune ?

Apexi ECU , they were going to use another car if they had a R34GTR there or power it up on the bench, so they must have something they can use?

I was coming home from Sydney after the new turbo, cam and new tune was done. had traveled about 300Kl, going great, like a new car, I was loving it, on a real twisty bit and having a bit of fun and the car cut out for a second or 2 and when the turbo kicked in it was shit, between 1500 and 3500revs before full boost it was fine, found a spot to pull over and the idle was rough and noisy and it conked out. Checked everything I could see and nothing seemed to be off or leaking, 45Kls from home, in the bush so I babied it home,the end :)

I will have the ECU back today, I will put it back in and see what happens.

Taking it back to Sydney next week for the Haltech Pro R34GTR, while I am there I will get a new exhaust system and fuel system and hopefully make it back home this time,haha

That sounds like an intake gasket blowing, I have had two Apexi PFCs one of which for 10 years and they don't just drop a tune like that that I have ever experinced or heard of

When I say check the tune, they would have to have a car with exactly the same mods setup exactly the same way so they can run it up on the dyno

What exhaust are you looking for, I have an bolton 80mm cat back blitz or apexi, can not remember ATM, I took of my 34 I'm selling cheap :D

Also have a chat to unigroup about their Blackbox or insight with his new EmTron, both of which I would consider better value for money

I am booked in for all of the work to be done.

I do not know about the gasket blowing, but when we went on Face Time with the FC hand commander the settings were back to original tune , the car was running VERY rich, rough and noisy at idle and we went through it, changed a few settings and got the car running OK and I changed the plugs, they were BLACK! I guess I could have just waited for the ECU to come back with the tune reloaded and just drive it hoping that it was a once off, BUT I have a lot of trouble getting to Sydney and will do all of this at once and get it over with.

If they used another R34 I would think they would just take the other ECU out, plug mine in and reload my Tune from their files , pull it out and replace the other ECU.

I have been after more torque down low as the car was a shit DD the way it was. As you can see from the Dyno last time Brown and the old Dyno Blue that it is getting much better :)and I expect a little better again this time.

I have the exhaust being custom made , I want it free flowing but not too loud, I am in a small town and once you get targeted, your stuffed :(

I have never heard of most things on SAU :)

BUT just installed the ECU and took it for a run, all good, well for now

He sent the hand unit back in case I have trouble on the way to Sydney, hope I do not have to unwrap it :)

    • The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.    
    • Bit wet, but YUMMY
    • Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.
    • It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....
    • Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
