hi guys,

my mate has a microtech LT-12s with plug and play for his R33, he is getting rid of it due top selling the car. However, i want to take it off his hands....but can this unit fit my rb20det? is the loom different? etc?

what would i need to make it...diff wiring loom? etc?

also what kind of price second hand should they be going for?

THANKS GUYS

you will need to swap two injector wires over (might even be able to do it in the software).

because the LT12S is full sequential you will have to change them, if you run group injection you will not even have to do that, but lose the benefit of full sequential.

look in the powerFC FAQ and its the same injectors you have to swap as you do when you use the Rb25 PowerFC on the RB20.

i can look it up if you get stuck, but yes, it will work on the RB20DET with a small wiring mod.

Yeah you'll need to swap the wires. Injectors #4 and #6 are switched between RB20 and RB25.

Is it the guy who wouldn't do COD to me?

Its worth $1250 for the unit, about $250 for the plug. Thats a little cheaper than retail, but thats what you can get stuff for if you shop around.

So second hand, $1100 is a good price... just not good enough that I'll deposit it into a randoms account before I see some goods, lol.

One issue I'm worried about with the plug in option, is loss of HICAS and A/C control etc. If you wire it in yourself using the loom, you can let the microtech control injectors and ignition, with inputs from TPS, CAS, water temp and MAP, then let the stock do the rest.

If you remove the stock ECU completely... your microtech will have to take care of the other stuff. Hit your tuner up about that one.

Its two wires.... which you just swap over... I think thats easier than sending back to microtech...

anyway, can you tell us more about the microtech's ability to take care of things like AC and HICAS when the stock ECU is removed completely? Or doesn't the stock ECU effect these things??

the microtech contols the air con or idle air & stuff like thermos etc

you can also run a 2 step off it

but you will need to let microtech know when you order to customize it

Thanks mate. I'm currently after a second hand one, so I guess I'll just assume that if someone else was running it in a street car and have no idea what I'm talking about when I ask how they controlled their a/c and shit... they probably had it all taken care of by the tuner and its already been sorted.

Just not keen to grab a plug and play, then suddenly get stalling problems when I use the A/C.

Almost seems like cheating just plugging it in, lol, I'm excited.

    • Thanks both. All good advice. Reminds me of drilling through stone wall for drainage pipe 馃槵 I'll let you know how I get on if I still have use of my hands afterwards 馃槄
    • Finally got shipping number for the intake and throttle body, shipped by UPS, so "should" be in my hands sometime next week, fingers fracking crossed
    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 馃ぃ, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
