Ok its safe to drive in the sense that you wont wreck your engine in a hurry. But excessive richness can wash oil off the bore, foul plugs etc. You will be safe to plug it in any time and play around just don't run it to and fro work and on shoping trips or drag racing.

You will find that it will be tuned in Matrix mode which is much better but at this stage there won't be any data in the tables. This will all start to make sense once you have a laptop, and read the book over and over . There is no point getting it tuned and not knowing what they have done for you.

That is the delemer second hand is always a worry but you don't have a choice do you. I got mine from a local importer that sells a bit over priced but his stuff is pretty good. Just the sheer condition of them when handed to you is all you have to go off. Have a good look for cracks and deteriated rubber! I payed $85 each someone on www.nissansilvia.com in the forums under used parts was selling 6 yesterday for $250 the lot or $50 each!

What are the advantages of the LT-12 over the PowerFC? I used to think it was just the price that was better, but Edge said it's $1650 just for the unit, without installation or tuning costs. That sounds bloody expensive to me. So you combine that with no closed loop mode and less accurate MAP sensor and in theory you get something with a rougher power curve/AFR as Joel's dyno chart suggests, as well as worse fuel economy. And there are also several people who have experienced difficult cold running/starting with it.

It doesn't seem to me that it does anything better than the PowerFC. Can someone please elaborate?

Note: This is not a flame or badmouthing of the LT-12, I am genuinely interested! I am only going off what people have said specifically in this thread, I don't know much else about them apart from what people have said in this forum.

JimX you make a valid point. There is no main thing that makes it better in fact i think it is not near as good as a Power FC except 1 for me as a self tuner the software is easier to use, as a person that likes to fiddle i can see all the displays at once.

2 Laptop conection no little hand controller your only inter face

3 Warrenty that is local

4 And the main thing they are suposed to be only $1395 if you get them off the right people.

5 A technical number to ring up if you have any dramas, which they are very helpful but are yet to actually solve any of my problems.

    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
    • The downside of this is when you try to track the car, as soon as you hit ABS you get introduced to a unbled system. I want to avoid this. I do not want to bleed/flush/jack up the car twice just to bleed the f**kin car.
    • But again, the engineers said your cast aluminium would be fine based on the load that would be stretching that section. Same load stretching the bolts in a flex (not the twist), with a much smaller cross sectional area than the original part you've broken. It's why you'd need to be using higher strength bolts, but that's just making up for the strength you lose with less area...
    • I am truly amazed someone on this planet was able to cycle the pump using a scan tool. I've always ghetto cycled them on Nissan 90s shit boxes by slamming the brakes and pulling the handbrake to agitate the rear wheels enough to cause a speed difference
