my RS4s ECU decided to die on me the other day >_< mech said all the outputs are fried!!...

ended up finding a solution with a Series 2 Auto ECU he had laying around...

and now my car actually feels like its running better and smoother.. and no longer so rich... (it was running very rich lately)

trying to source another manual ECU at present via JDM..

is there any potential issues with running the auto ECU in my manual ?? Mech was very unsure if there would be ramifications.... :unsure:

If I can't find a reasonably priced manual ECU.. might just have to get myself a Vipec after I get my clutch done... *sigh* that time of the year I guess..

(thanks for the info Cam / Scotty)

yeah according to Mech the wiring was 'spaghetti'.. not sure what had been done previously in there, but its been sorted out apparently.... got a pretty hefty labour bill at the end of it though...

(and an empty tank for some reason :/ .. will have to question that one.. was 40km on the o.d.o since filling up)

and a $300 deposit on the auto ECU, (hence trying to find a manual one cheaper for the moment, then give it back)

Tomas there is no problem or difference for running the auto ECU in manual. The auto has an additional function to cut timing when the gearbox says there is a shift taking place - but since there is no gearbox to send the signal that will never happen.

I ran an auto ECU in my manual for about 18 months until other mods meant I needed to go aftermarket.

Also, auto ecus will be everywhere....but manuals will be much rarer just like the donor cars

oh that's a relief :) .. I didn't modify my ECU, but then, I wouldn't know what's inside it.. I might go grab it now and open it up.. ... ok looks pretty stock.. no mods!

might just pick up a second hand auto ecu cheap, and give the other one back (as there is some issue with it which is why its his test one)!!

anyone got a spare S2 Auto ECU they'd like to part with ????? :D

I don't, but you should see them come up time to time, for about 1/10th what your tuner charged you. Make sure the part numbers match, there were smoe pinout/wiring differences in some of the models.

part number for mine is 23710 0V801 JECS TM

not sure what the Auto ECU number should be? does anyone have a list of which ones are compatible?

or at least how to tell which one is series 2.... did a quick search and can't seem to find much info.. (even looked through the stagea parts list thread)

There are three different S1 ecus and thus three different looms. Earliest and most common is the OV300 followed by the OV301 and then the OV310

Series one are Hitachi Series 2 are Jecs. Some S2 ecus are OV810 and OV811

Grab this one really fast if its still available - fully tunable - worthwhile even on a stock motor!!! http://www.skylinesaustralia.com/forums/topic/407534-nistune-s2-rs4-neo/

I like what you're doin' there Leon.

Also, clear tube is for catch can?

Thanks Cam.

Yes, catch can under airbox. I just replaced the abomination of multi sized tubes that was my last effort. The clear will be decidedly brown in a few months, lol.

Doesn't the clear tube to the catch can suck itself closed under idle vacuum? It gets pretty soft once the hose heats up

Not in this case because it isn't routed back to the plenum. After the catch can it goes into the intake before the turbo. At idle it is subject to atmospheric pressure only.

Just fitted Dale's Piano Brace. Awesome stuff.

Now just have to finish installing the wideband so I can put the dash back together.

I can't believe how long the 'piano' reference has hung around, lol.

Leon, do you have the PCV valve catch canned on the other rocker cover (assuming VQ25dets have the same PCV set up as VQ35des)?

Thats the one that would suck closed. I went and bought some heavy oil resistant pipe from pirtek for it. The one you have catch canned, and correctly I might add, required both vacuum and pressure. So it has to be able to suck in and blow out. I believe that the PCV is more important to catch can than the other side, because it has move vacuum drawing oily gas out and into the plenum. Thats how I thought it would work best anyway.

yeah, that's the one I have the catch can hooked up to - between the PCV & the plenum chamber just above the centre inlet runners

at idle it was sucking the hose closed so i ended up using some 3/8" brake booster hose which has enough reinforcement in it to stay open under vacuum

Yes & no. It is there but not hooked up. Everytime I connected the hose my old turbo would smoke because the seals were shot. It must have been adding pressure to the system. Maybe my PCV valve is stuffed, although it seemed to be doing it's job when I removed it to check. I have literally only just got my new turbo in (& now not leaking :) ) so I can connect the catch can again & see what happens. Hopefully my PCV doesn't allow boost into the engine & the pressure blows out something important...

Alex, I know you stuffed your can with steel wool. The theory is to filter the oil out of the air better, right? How long did it take to poke it in thru the drain hole?

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
