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

    • I have no hard data to report, but I have to say, having driven it to work and back all week, mostly on wet roads (and therefore mostly not able to contemplate anything too outrageous anywhere)..... it is real good. I turned the boost controller on, with duty cycle set to 10% (which may not be enough to actually increase the boost), and the start boost set to 15 psi. That should keep the gate unpressurised until at least 15 psi. And rolling at 80 in 5th, which is <2k rpm, going to WOT sees the MAP go +ve even before it crosses 2k and it has >5 psi by the time it hits 90 km/h. That's still <<2.5k rpm, so I think it's actually doing really well. Because of all the not-quite-ideal things that have been in place since the turbo first went on, it felt laggy. It's actually not. The response appears to be as good as you could hope for with a highflow.
    • Or just put in a 1JZ, and sell me the NEO head 😎
    • Oh, it's been done. You just run a wire out there and back. But they have been known to do coolant temp sensors, MAP sensors, etc. They're not silly (at Regency Park) and know what's what with all the different cars.
    • Please ignore I found the right way of installing it thanks
    • There are advantages, and disadvantages to remapping the factory.   The factory runs billions of different maps, to account for sooooo many variables, especially when you bring in things like constantly variable cams etc. By remapping all those maps appropriately, you can get the car to drive so damn nicely, and very much so like it does from the factory. This means it can utilise a LOT of weird things in the maps, to alter how it drives in situations like cruise on a freeway, and how that will get your fuel economy right down.   I haven't seen an aftermarket ECU that truly has THAT MANY adjustable parameters. EG, the VAG ECUs are somewhere around 2,000 different tables for it to work out what to do at any one point in time. So for a vehicle being daily driven etc, I see this as a great advantage, but it does mean spending a bit more time, and with a tuner who really knows that ECU.   On the flip side, an aftermarket ECU, in something like a weekender, or a proper race car, torque based tuning IMO doesn't make that much sense. In those scenarios you're not out there hunting down stuff like "the best way to minimise fuel usage at minor power so that we can go from 8L/100km to 7.3L/100km. You're more worried about it being ready to make as much freaking power as possible when you step back on the loud pedal as you come out of turn 2, not waiting the extra 100ms for all the cams to adjust etc. So in this scenario, realistically you tune the motor to make power, based on the load. People will then play with things like throttle response, and drive by wire mapping to get it more "driveable".   Funnily enough, I was watching something Finnegans Garage, and he has a huge blown Hemi in a 9 second 1955 Chev that is road registered. To make it more driveable on the road recently, they started testing blocking up the intake with kids footballs, to effectively reduce air flow when they're on the road, and make the throttle less touchy and more driveable. Plus some other weird shit the yankee aftermarket ECUs do. Made me think of Kinks R34...
