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.

If your going to go with a microtec in a FC here is the best way to do it..



Buy a LTX8 w/wide band input and get the wide band o2 kit and the 3 bar map sensor. I'd also recomment getting the dash as well.. Use a FD upper and lower intake manifold and FD throttle body also use the FD front cover and crank/tdc sensors and the water pump and water pump housing... you will need to let them know you are using the FD TPS, crank sensors, water temp and air temp sensors when you order it so they can preprogram it to run on those sensors. You can use the stock coils or aftermarket ones. I'm using Accel GM type coils on my FD with the 20B.... If you use the GM type coils then you will need to run the second plug wire off each coil to ground and you will need 4 of them... if you have any more questions just ask them and I'll try to get back here in the near future to answer them for you... There will be a newer version of the microtec comming out in a month or two that will be a little better, so you may want to hold out for it if your not in a hurry..

As far as standaloes go do you guys think that the microtech is a good unit? Or should I hold out a bit more and get a haltech.



i have heard alot more on haltech's and seem to be the better choice as far as support and knoledge on this board at least. I looked in the ECU Maps section and not 1 microtech map so I guess not to many people use it.



Over all do you guys think the haltech is a better choice over the microtech?





And dragon my car in an N/A S4 I dont think FD parts are in order here LOL. Mabey on my turbo motor but not on the N/A

the tps doesnt matter the haltech and microtechs basically only use it for idle, accel pump, and full throttle (if you even have all of these turned on)

Do these ECU's come with the map sensor?

if you stay na the stock one works fine

Microtech does offer the LTX8 w/ a built in MAP sensor on the ECU itself..u run a vac line into the car..but other then that, its not bad.





BTW, yes..I do think Micortech's are a very nice system for the money...a little harder to get tuned at first(or so it seemed)..but still def worth the money..

would you prefer a hlatech

i'm more comfortable with a haltech, but thats just me

I will hold out for the haltech then. With the haltech I would not have to ship out the ECU to change the base map right? like im N/A now but when i do my TII swap i just change the map or what?

yeah its a couple of settings and soem remapping.

I just asked Tim from microtech about the whole thing from going NA to Turbo maps. I should have a reply in a few hours.



My LTX8 is awesome. I love it soooooo much. And Rotaryman, the LTs have a built in MAP with the option of an external. Come on, you of all people should know that since we sell them. https://www.nopistons.com/forums/pub..._DIR#>/dry.png

Just heard from Tim.



He said that all rotary LTs are the same, they just come with a different base map. There is no need to have it reprogrammed.



So just buy a Microtech LT8. I can probally have one made for you so that you have both the NA and turbo base maps on there.

Hi all,

I run an Ltx-8 on my 13bt.........Compared to the Wold3d I used to run this little beastie is hot.......Easy to set up, easy to program and it has all the features you'll ever want....

You should stay with the original coils and ignitors if you don't want to bugger around with the electrics..... I'm running 20 psi with the standard ones and haven't had any problems.



Definately look into the data dash, it has lots of great functions such as shift light, overboost warning, temp warning (air and water), log functions etc. it can also hold 4 additional maps in its memcals.



you can get the ltx with the turbo base maps and use it on your n/a until the new barrell comes along...It will run fine but just won't use the turbo mapings extended (positive boost) fuel and boost retard.



hope this helps

Rossco

yeah i was looking into a micro tech lt8 as well i just dont have the money for a haltech unfortunantly but it would be for the turbo2 swap so i could just get them to send it with the base turbo map... what other options are there aside from microtech and haltech? oh yeah and wheres kevin haha i need to ask about his ecu. what about an adapter that uses the old wiring harness and hooks up to the microtech

The Microtechs have an adapter so you can use your factory harness. I have to look up the price for it, but we can get them.

if you price out all the stuff to make the mt compareable to the haltech feature wise the price difference is like $80....

Yes, this is true..but I'm not the one who deals with them directly all the time, thats what we have you for https://www.nopistons.com/forums/pub...#>/biggrin.png

BTW, ur options for aftermarket EMS would be:



Haltech

Microtech

Motec

Electromotive TecII & TecIII

and PowerFC for the series5 guys..



There are ton of smaller off-name companies too, but those are the main ones you'd see on an rx7.

sds

autronic

megasquirt

aem





there are more, i've heard good things about f.a.s.t. and speedpro but I have no knowledge of their use on rotary engines, yet.

First off thanks for all the info.



I am stuck in the cross hairs LOL



I think I will go microtech and get that dash thing. Roadkill669 do me a favor find out how much the following will cost. The Microtech LT8, the Dash Unit, & the adapter to use the stock wire harness. I want to save the Microtech's harness for the nice clean engine bay after the TII swap.



With that dash unit I can get rid of my idiot lights right? It warns of over temp, oil preassure, and other vitals like that? I want to put a 7 inch indash Monitor W/dvd in there https://www.nopistons.com/forums/pub...1047683329.gif

So how much would all that be?

do u guys knwo if microtech cameout with the new series for teh NA yet with a wider range off boost map? i heard this was in the works but not sure if its out yet.

IN A FEW WEEKS

I don't have any experience with the microtech so I may be off here, but I'm guessing the microtech 'dash' does not provide any facilities for idiot lights or any of the crap the microtech doesnt know about.



the microtech is not going to be wired to your oil pressure, fuel level, washer level, oil temp, or anything else that isnt related to the function it does (manage the fuel and spark of the engine).



the dash probably has rpm, boost/vac, coolant temp, and air temp... maybe other stats like how much fuel it's injecting/duty cycle and current ignition timing.

That is correct. It only has warning lights for boost, oil pressure, and water temp. It also has a shift light and a display for your stats.



I'm not home right now so I can't give you a price. I will be in a few hours so I will look it all up and post the prices.

E-mail some of the big name tuners and ask them what they like the best. The replies that I got did not rate Microtech all that highly. However, they did say that if all you want to do is start the car drive to staging and do your quarter than they are perfect.



If you want good sound advice from professional tuners try some of the groups and messageboards.



GregW

I know about the washer fluid and **** like that but Im talking about engine Vitals. The rest like doors open or low fuel and low washer fluid that is **** that you really have to be an "IDIOT" to not notice.

all i was saying is the stuff the microtech doesnt have wired to it for manage the engine won't have representation in the microtech dash.



this includes 'engine vitals' such as oil pressure and temperature. It also includes the other idiot lights that I mentioned. There is no difference between them when it comes to implementing them as a lcd dash, the problem is the microtech doesnt have the analog inputs for the extra stuff. If it did, it could have a washer level indicator on the dash just as easily as a oil pressure one.... at the input level it's all jsut voltage.



if you were interested in throwing away your stock gauge cluster and having all your gauges and idiot lights on a lcd panel... you could do it with a standalone and a extra computer+lcd communicating with the standalone and displaying the engine data in realtime from the standalone as gauges. Then you could add more data acquisition to the extra computer with a general purpose analog to digital converter on say a serial or parallel port... and just wire the extra inputs up to it. Then integrate those inputs into the screen alongside the gauges showing the ecu data. I'm doing this on my car with the haltech e6...

Here are the prices:



LT8 - $869

2 line Dash Unit - $359

Handset - $129

Laptop Adapter - $100

Plug-in Harness - $169



You would only need one or the other between the handset and laptop adapter and you only need the plugin harness if you want the Microtech to be a "Plug and Play". I will also see if I can get you one with both the NA and turbo base maps on it so it will be a little easier.



Here is what the dash unit does.



Main Display

- Built in Digital Tach (Bar graph across the top ith a rev counter also)

- Water temp/ boost pressure display (when boost occurs, water temp will display boost pressure



Data 1

- Engine revs and boost (first line)

- Timing advance and injector open time (second line)



Data 2

- Water and air temps (first line)

- Timing advance and injector open time



Data 3

- TPS and battery voltage (first line)

- Timing advance and injector open time



It also has a warning light that you can set for water temp, air temp, boost, and you use the AUX input of the LT8 for the oil pressure. It also has a programmable shift setting.



The Dash Unit can also be used in place of the handset, but they don't reccomend that because the unit wasn't designed to be an everyday handset. But it possible.



I also have all the specs on the ECU and everything else in PDF format if your intrested.

I can order it str8 from you? and yeah post or send me an email with the info RX713B4URAZZ@aol.com
