If i want to run a microtech which should I get the LT-8 Or the LTX-8? If I get the LTX-8 can I still use the stock coils?

What is everything I will need to install the ECU including sensors and what not. I also want to get rid of the damn AFM.



With this ECU if I go turbo all I would have to do is change the map or what. Im thinking of buying this to throw on my N/A till I go turbo.



I know it may sound stupid but are there any power gains from going standalone?

LTX-8 requires aftermarket coils.

why?

OK considering that I Use aftermarket coils what else will I need?

wish they would provide more details than that



perhaps they can't handle 'dumb' ignitors.

Forgive my ignorance but cant the stock coils be configured to be used with out the stock ignitor. And are there any sensors that I would need that dont come with the ECU.



What can be done about the POS TPS can it be changed once I go standalone? Also about getting rid of the AFM any thing special needed?

You can use a MAP sensor instead of the AFM. Not familiar with the microtech but I imagine you can use a MAP sensor with it.

Stock ignitors will be fine unless you're topping 10's in the quarter.



When you order the Microtech LT-8, you'll get a flying harness that you simply attach to the stock sensors on your engine via solder and shrink tubing. No sensors come with the unit. You will then be able to ditch the AFM, along with all the emissions stuff and whatnot. The ECU runs off manifold pressure, not the air flow meter.



If you go turbo, you either need to change the map manually or send the ECU back to Australia (might be someone in the states doing it now) to get a base turbo map, which I recommend. It's free and gives you a proven base.



Power gains are unlikely unless you get it professionally tuned. If you're planning on doing the tuning yourself (especially off dyno), it will be very hard to get a better power curve and your mileage will hate you. Microtech's are great because they are cheaper and do the stuff you need, but for n/a's, there's not many load points so it's hard to get a perfect curve.



I liked mine when I had it, though. Hard to compare directly as it was in a first gen with a S4 13B.

You may also want to talk or PM to Dragon, He has the LTX-12 on his 20b in his FD. He studied it for a while before he purchased the unit, and may be able to give you a little more insight on the sensors and coils used.
