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.

    • Behrman is great quality stuff. My 34 has some serious clouding as well but I’m too nervous to try and replace the glass myself so I haven’t bought them yet. 
    • This might be true if you live in NZ but I can't see how this could be true for us locals here.  I've found the customer support for Haltech to be absolutely amazing. I've turned up to Haltech and spent entire days with their tech support guys, they've even helped me with wiring dramas that had nothing to do with their products.  They have the best customer support of any company I've dealt with, I can't imagine how my experiences with them could possibly be any better.
    • If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.
    • Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...
