Still no one running LT-12's yet

[Trotts33]

The auto elec was worried about getting a signal from the AFM if plugged in, RPM said to remove it all together which I will do later.

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.

[Trotts33]

Its not my normal driver so I'm lucky. When on the dyno with orig ecu it was running so rich its lucky it ran at all. I think thats why I can feel such a difference.

[Roy13]

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.

[Roy13]

Did you fit the air temp sender?

I mounted the lt-12 under the glove box so the map sense and air temp wire are always pluged in just a simple change of the main plug. Which is much easier to swap and not be tempted to drive with the lt-12! Hint Hint

[Trotts33]

Read the book over and over, your not wrong there, heavy reading in my case. I'll plod along and take care. Thanks for the pic, we did find a crook one (coil) but got around it for the time being.

[Roy13]

Its good to know that you idle is a bit sus too it has been a headake for me for a while now! How did you go with the miss at 5000rpm

[Trotts33]

Will the loom stretch up there? Must. I'll try it. RPM sent instructions to use the orange wire with blue trace from the AFM, so we spliced in and to change setup just unplug one and plug the other in.

[Roy13]

Well i'll let you get a laptop sorted out and then you will have a mirage of questions you'll want to ask me! I'll catch up with u.

[Trotts33]

Used plug lead and bosch hand held scope, found faulty one but while doing so discovered that while coil not mounted misfire went. Up country fix while waiting for parts, leave plug lead in and zip tie coil to breather pipe. Works but very temp.

[Trotts33]

Ta, I'll keep in touch.

Cheers

[Roy13]

Ok i though Rpm was doing it this way. You have to make a braket off the firewall. And the main haness has a plastic locator at the bottom of the std computer, disconnect that and the harness will stretch right up!

[Roy13]

Oh buy the way i know of some cheap coils if you need some!

[Trotts33]

I do so let me know. We were wondering how do you know if second hand coils are any better than what youve got.

[Roy13]

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!

[Roy13]

Forums, then got to Parts - no trader adverts please, then ( actually carn't find it myself now, was only reading it an hour ago ) The guy was in Brisbane thought so it woud have to be a sight unseen COD. Risky!

RPM worked together with Microtech for the Plug and Play.

[JimX]

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.

[Cubes]

I personally would go the PowerFC if I could but.. If the new Microtech has closed loop etc then it will be just as good.

[Roy13]

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.
