The big advantage of the new R33 Microtech is that the standard loom plugs directly into it! Easy. and it uses the standard electronic boost controller, to create the different boost levels. ie. you don't have to buy a new one of these.

Don't forget to price in labour of installing new wiring for an Autronic as well as extra dyno time.

Edge the MTX-12 Microtech has been out for some time now and are readly availably. check www.horsepowerinabox.com

There is a newer MTX-16 that hasn't been released yet (in the next couple of months) that is supposed to have closed-loop and reads form speed sensors etc.. Hence maybe a possibility of traction control however nothing is definate yet we willhave to wait and see :) So keep an eye on it.

Autoronic would be my choice of ECU if I wanted to spend $2.5k on a ECU however I will be looking at around 1.5k. Hence the Microtech.

So is $1500 insalled and tuned, (im assuming at that price your not getting a hand controller)

If thats installed and tuned then that is a good price, i dont know of anyone in Sydney that could match that price.

Even though its a plug and play ECU, there is still a little bit of labour and cost in relocating air filters once AFM is removed, buying and installing the air temp sensor (they didnt supply with the MT8, is the LT12 different?)

$2500 for the autronic installed and tuned so the thing doesnt stall when you turn the air con on, or turn the steering wheel at idle represents excellent value.

Joel - Thanks for that info.

Nice so a LTX-16 is coming! How much will it be?

Wish I was still waiting before purchasing one for mine. I got mine including hand controller, all up including dyno tune cost $2100 + self install of the air temp sensor, and piping the inbuilt map sensor and plugging in the computer into standard ECU socket.

I was talking about the LTX-12 Plug N Play for R33 which has R33 connector dongle and immediate drive away tune, that PNP only came out in the last few months.

It also has laptop connection and software included. Thats what the "L" stands for.

Joel - it is plug and play with afm but as I said before it is best to install the air temp sensor with the map sensor and tune it soon after install because otherwise it will run rich. If you are going to do this then it is best to go the air temp sensor and map sensor - very easy and technically just as accurate because the pressured area (engine) does not change. The map sensor is built into the LTX-12 (same as autronic) - just run a short hose to the same nipple on the manifold where the boost guage connects with a T piece.

What is the point of buying a programmable race computer if you arn't going to tune it to make it efficient (and save fuel) on your particular engine? Sure the timing will be more advanced and more power but it will be running rich, not very good for spark plugs.

AFM's provide more accurate measuring of air and for a street car provide a better drive, economy etc.. compared to a map sensor. So i've been told. Maybe there is stuff all in it and not worth worry about who knows. I'd rather stick with the AFM's due to the stock look as I don't want to risk being pulled off the road.

The R33 Plug and play has been around for a while in SA from RPM performance which I think Tim (www.horsepowerinabox & RPM) actually worked together with microtec to develop the plug and play.

I'm not exactly sure on the 16 I've been told it will be 200-300 dollars more over the 12. It may end up being more who knows :D

I've heard a little on what features it will have but nothing is definate. ;)

Just letting you guys know i started this post because i HAVE a LT-12 plug in Microtech.

I have located the air temp sender under the existing air scoop so it is not easily noticed and the AFM is still in its place so when i get the sh#*ts with the microtech i can plug in the std computer.

I can tell you that the car will run with the std maps but run like crap in the sense of drivability and idle control (i'm still yet to believe the idle will ever be right) so the first thing you need to do is get it tuned as well!!!

Also i recomend the purchase being from RPM Adelaide as Microtech Sydney will RIP YOU OFF BIG TIME if they give you a good price make them fax it to you or they will charge you extra on your card and not refund it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Joel, you can plug the Microtech in and drive away without removing the AFM. But the Microtech is not using the AFM, its still using its internal Map sensor.

Also if you leave it in place then you can plug in the OE ECU at anytime, but one of the benefits of running a MAP sensor is minimise inlet restriction, ie able to remoce AFM.

How much of a restriction it is doesnt really matter, its not doing anything so you better off removing it and flogging it off to an SR20 owner.

Freebaggins R33 is running a Microtech with no AFM. His AF's are a little over the place and the power curve isn't that smooth.

Where as Gregpins R33 is running the PowerFC with the AFM still attached. The AF plot is perfect and the power curve is a lot smoother with little or no dips.

Then there's the remapped RB20DET ECU. Appears to be running a little to lean that possibly is causing a slight loss of mid range power.

Yer... I really want to keep the standard look incase I get pulled over. I'm using a Q45 AFM when I get my hands on it with the rebuilt RB that i'm currently working on.

in running the lt12 also. with my setup 25det with a td06 no airflow meter seems to work well. Ive got to map seting set up, one with avgas at 308rwkw at 1.6bar and the other for premium 268rwkw at 1.4 bar. havent had any probs at this stage

      Rob's S Chassis track cars. Now with more s15 and less 180sx

      By robbo_rb180 · Posted

      Also did some work to the shed and a massive clean out of stuff. It's now got a small fab/dirty room and has helped keep shed cleaner. Built some new work benches and re organised things also got a TV out there so good having something playing while working on the cars. Got a pedestal drill and linisher off a mate that need to pick up too.

      R32 GTS (RB20DE) Injectors Replacement

      By Murray_Calavera · Posted

      First thought, have your current injectors flow tested. If they test fine, keep the diagnostics going. It's not the injectors. If the injectors are the issue, find some new or used (cleaned and flow tested) injectors.  While I really love a good excuse to get a modern ECU installed, just needing new injectors probably isn't a good enough reason to do so.

      A bit from column A, B and C. Mainly C   Update time, after deciding it was time to tick off a bucket list goal I finished up full time at MSR and have gotten back behind the wheel and making progress on the S15. Goal has been to drive Bathurst at an event and I have had my entry accepted for Challenge Bathurst in November. Since I don't want to go unprepared I need it running to test and get comfortable.  Been chipping away at it and started by stripping inside, getting it all cleaned and sealing some holes up. With stripping inside I removed the whole wiring loom and found a few surprises.......... its pretty butchered and shit branching and I'm not a fan of the haltech fuse boxes so it's all out and trying to come up with a plan to rewire it all either new fuse/relay box or pdm.  I haven't been happy with how I did the intercooler mounting and been wanting to tuck it up under rad support. O e issue with that is headlights will need a decent trim or get replacement covers. Took the time to mount it with some stand off's and new hardware. Stands are some m8 button bolts, washer, aluminium tube and factory radiator top mount rubbers. It's nice and solid also stiffens rad support which still requires some trimming. Bonus of factory rad mounting is used all factory hoses just need to weld a pressure cap to radiator now. Got sensor block and fuel filter mounted. Plan today is to get vac lines all sorted with push in nylon tube and design oil cooler mounting solution.  Been driving BRZ a heap and went out to Morgan Park for time attack and went pretty well for a wet day. https://youtu.be/gAlQgcQpWj4?si=kojOAOjhhX_X3AXR Getting pretty comfortable in it now and want to do a few more bits to it but restraining myself as don't need 2 race cars at the moment.

      Anyone know this frontpipe?

      By Murray_Calavera · Posted

      @sunsetR33 There is obviously a huge culture gap here. There is nothing in place like this in Australia, where if you fit a Mines branded pipe and later replace it with a Jun branded pipe, both pipes are essentially identical - BAM - huge penalties! Where is the Mines pipe?? You can't have a Jun pipe when you said you had a Mines pipe!  Makes no sense to me. Surely makes no sense to anyone else here either.  I'm sure a lot of us would agree that our registration/engineering system is pretty stupid at times, but it's not that stupid.  *** More serious question here. If you replace a factory rubber hose with a silicone hose, is the car illegally on the road now? Does it become legal if you have certification of what brand the silicone hose is? Then would it become illegal again if you replaced that silicone hose with a difference brand of silicone hose? And then would it become legal again if you had certification of the new brand of silicone hose?  I really want to know that answer to that question.

      Good you making progress with this rig. Aluminium welding is painful to learn, have you got a pedal as I found it so much easier with one. If that's the AMG I think it is, you would working with Benny?
