Don't get me wrong, no way does it drink the juice, it's just worse than when I had the factory ECU installed but that being said, I now have 30 more rwkW to play, and when I play it then drinks the juice!!!

If I try and get good fuel econ (it's a daily drive car) I can still get 12-13L/100km around to and from work which is pretty good. Try that in a 5.7L V8 that has less power!

I used to have a microtech mt8 on my 200sx but it was just crap...

From time to time,the car would experience power surges and will emit black smoke...

I went to my mechanic and they tell me that Microtech is more unpredictable and that the problem was not with the tuning(he did not tune the car for me) In fact they refused to do any more microtech due to the problems....

I mean different mechanics have different feelings about products but my own experience seems to prove his point.he seem really good with his experience,good business and project cars(e.g. the 800kw ute Judge in one of the magazines....

Personally I have a few ideas of mine about ECU'S,

1.)I think ECU as the brains of the car is the most impt and should be done probably once and for all(I think aside from motec, the prices of the rest are just a few hundreds apart???

2.)The tuner is very important too.If this is badly done, the chances of busting your engine or some other stuff is higher similiar with a lousy ecu in the first place...

3.)aside from motec, My personal choice is firstly the HKS fcon pro series.Firstly they are used by the major japanese tuning companies seen in mags followed by power fc or links(I raced with a WRX with a possum bourne link and it is really good the owner swear by it

Another advantage is that the hks ones can analyse data faster than say power fc but the problems is no one seem to be able to tune it in Australia....Well if anyone know who can tune it in Melbourne,please tell me!!!

Well this is my own view please tell me what u guys think:)

As you said, you've gotta remember is that an ECU is really only as good as the guy tuning it. I've never used a Microtech ecum, but I'm sure with a good tune, they're still a very capable ECU...

Out of interest, does it have the ability to detect knock? And what's the cold start like?

I'm running a PowerFC, and to be honest, I don't know any good reason why people say they're only good for a car with mild mods. I got told by about 5 people that for the power I want, the only ecu that'd do it would be Autronic or MoTeC. Only ecu I'd take over this is the MoTeC, and that's only for the MAP+TPS ability and the extra data logging facilities.

I've got a 3ltr motor, big cams, T66, bigger injectors, etc etc etc, and i still can get 400km+ to a tank if I take it easy... Powerfc handles all these mods flawlessly.

I've attached my dyno to this so you can see that there's not one flat spot, the torque dropping off was just the turbo dropping off boost top end (avcr not set up). Oh, and that's only running 16psi.

BTW - I'm in Melbourne :)

Your right matlowth,

For the current crop of $1300-2200 ECU they're all good, but if your tuner aint switched on then the perception is that the ECU you've got is not.

Microtech has no knock sensor and cold start is fine.

Whoever told you that your gonna have to ditch the Power FC are wanking themselves, how many 600-800HP GTRs have we seen in Zoom and HPI with Power FCs! The only limiting factor might be the AFM flow restriction, but you can get a twin Apexi setup that could eleviate that anyway.

BTW, huge power youre getting! What gear was that dyno run with? Also are you running aftermarket fuel reg and what intake system do you have?

Cheers,

Freebaggin.

Exactly :)

Cool - that'd be my only concern with it then, have you invested in some aftermarket knock detection?

That run was done in 4th gear, and nahh - standard regulator, bosch fuel pump and some 550cc injectors. Intake system is a apexi pod, z32 afm, and a blitz 4" front mount. There's heaps of restrictions all over the place with my current setup, and it's still got the standard cross over intake stuff...

Won't worry about knock detection at this stage, I'm relying on Tim @ RPM to tune enough safety in it to avoid the need. However the knock detection on the PFC is a v.good feature and I'm sure later down the track the lads at Microtech will have a module that will do the same.

Looking forward hearing how you go with improved intake system!

turbogtst,

How the hell would you know how the Microtech goes for drivability in R33s anyway?

Can you do laptop data logging??

Do you need AFM? Yes, and if you didn't have it then you probably be making more power.

Can you monitor engine functions with hand controller?

Can you control extra injectors, NOS, boost, run injectors of any resistance all controlled from the ECU?

Blow it out your arse before you make statements like "can't beat the factory ecu".

How did you deal with VCT activation when using the R32 ECU? Did you ditch VCT or does the ECU have "spare" outputs that can be used?

How would I know about the microtechs driveability in an R33 is because i had a MT8 in my R33 previously and the LT12 is the same computer just with a connector.

If I thought the LT12 was any good I would have one now, the laptop software looks fancy and is really good it just a pity DOM wont spend a bit more time writing decent software for the load points, they are good for all out horse power but as far as fuel economy, driveability and tuning are concerned they are crap, If you dont beleive me just wring some of the professional tuners and see what they have to say.

How many tuning points does it have, from what my MT8 manual says they have 16 points from 30" hg to 20 psi boost, the r32 gtst ecu has has 256 points, Try and get the Microtech to idle at 14.7 to 1, impossible, no probs for the factory ecu without closed looped, and i have a EUGO Air Fuel Ratio Meter so I know mine is right.

What do you need all the extra outputs for, and the r32 ecu can run either 2 or 14 ohm injectors i believe they are only 2 available.

And what about closed loop they cant even do that no wonder they use so much petrol.

Anyway I will never own another Microtech and i suggest to any one who is thinking of buying an aftermarket ecu that they buy a Haltech or Motec it is definetly worth the extra money or just stay ed with the factory ecu's and get it remapped.

I control my VCT with another board that i have installed in the ecu, but you can use a ecu out of a Z32 twin turbo as it has VCT output and can be remapped.

TurboGTST,

Just wondering, did your car come with the R32 computer, or did you do the swap/remap yourself?

And who did the remapping?

What sort of cost would people be up for for such a swap (including the VCT board you mentioned).

I had a quick look into doing a swap a while ago, but the VCT thing got me stuffed.

Any info you've got to help me out would be great.

Share your wisdom young Jedi :cool::D

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
