Thanks Dale and Jon! I am quickly becoming a Microtech fan! I did eventually find a spec sheet and I saw what outputs were given and what type etc....and it sounds really good for my setup.
By the way, the RX7 Series 4 Air Conditioning has it's own stepper motor drivers for the vent door position and heat, so no worries there. All it needs is batt voltage.
As far as gas mileage goes, I guess that will take some tunning, but I should still be better than stock even with my setup....SO I now need to decide and based purely on $$ the decision is rather a "no-brainer"
I REALLY like the idea of the handheld controller vs. a laptop. I will do the initial tunning with the laptop and then make different maps for driving to work and the strip, and the track. I am exited about this setup!
I am adding my name to the list now.

I think that I'm definately in on this deal. But I have a question....
It comes with a flying harness but uses the stock sensors, so I'm guessing you unplug all the sensors from the stock harness and yank it out, but how are most people connecting the new harness to existing sensors? I don't want to cut off all the stock plastic clips, and was wondering if it's possible to modify the flying harness to work w/ the stock clips using electrical connectors found at sears/radioshack etc....
if i go to sell the car, it would be nice to be able to just pull the microtech and put the old ecu back in.


My other question is do I really need to get the Bosche coils or is it a waste of money for my setup. I don't plan on pushing more than 300hp. I have a 3" exhaust system, and will be adding a td06 20G(or similar) turbo, larger IC, and 4x720cc injectors. Yes or no?

 

10sec rx7....one more question about the software....

What does "load" mean. I'm referring to the first screenshot you posted earlier that graphs Load(y-axis) vs MAP (x-axis). For example at the reference point of 8psi, the load is 7.86. What does this mean? How do you tune by these numbers. Also, is 7.86 an input that you enter, or is that a number given by the computer being read from the sensors?

 

Just thought I'd chime in to mention that I got my LT-8 last summer after running through the standard list of questions with 10sec rx7 and I have been simply amazed at the simplicity of the install and the easy tuning procedure. If you're not already in on this group buy, get in now! If I knew what engine was going in my current project, I'd jump aboard too, but I just don't know yet so I'll have to wait a couple months before I buy my next microtech.

Great system, great support (from company and everyday Australians), great software. All around great. Get it.

 

Spool up.....No you don't need the bosch coils.The standard mazda ones are pretty damn good.Stick with them.
The 7.86 you are looking at is the injector millisecond value.
For example,at 8 psi your at 7.86 m/s & the car is running rich,you lower the m/s value down until the mixtures are where you want them to be at that specific load point which in this case is at 8 psi.The LT is adjustable in .04 m/s increments so from 7.86 m/s,one click down on the button will give you 7.82 m/s,then 7.78 m/s,7.72m/s & so on.
Hope this makes everything a bit clearer.

any pictures of this unit? and possibly the new hand-controller or dash controller.

 

I do have some pictures of them yes but have absolutely no idea how to put them up here.If someone can show me how to then I can do it.

 

Just wondering is the only difference btwn the LTX8 and the LT8, the 4 coils? Also is it worth the extra $100 or so to pick up the 4 coils? what are the benefits over stockie's?

thanks,
A.L

 

The only difference between the 2 is the coil driver inside the box & the fact that the LTX comes with the coils.The bosch coils are slightly better but there isn't a lot in it.unless your planning on trying for well into the 500hp at the wheels range,the standard coils are sweet.
Jon

 

I'm with you on this one, and am currently seeking a low-cost solution. You can either do as you've said, and reuse all the clips on your existing harness (by cutting them off) or replacing them with new ones. Unfortunately, since the LT8/LTX8 uses all the stock sensors, there are a few that are Mazda-specific. BlackFC has found a connector kit from summit that will take care of most of it, but I need to call Mazda and see if I can buy the others that are needed (i.e. CAS). An announcement will be made on the email list.

Just as an idea,
I am using all the connectors off of a J-Spec engine. Almost all of the engines come in with the connectors, but the wiring harnesses are all cut off. This means that there are a TON of them being thrown away because the harnesses are no good.

I have 2 sets myself and I plan on selling any extras for real cheap. Go to FC3S or any forum and just ask for connectors. I bet you can get a set for really cheap and they will work. There are a couple of connectors that are different, but %90 of them are the same. Try that......

Greg

 

Guys,
Jon has answered all the questions so far, so keep on asking and we will keep answering them,

as for the connectors, if you have a S4 86-89 then the connectors are not a problem they are avaliable from microtech for a very small fee,
th S5 motors have different plugs that as far as im aware are not avaliable easily anywhere,

90% of people here cut the plugs off the standard loom

i have a few pics of the handset on my laptop, i have a MTX8 and a LT8 in my garage ill get some pics of them in the next few days for you guys.

Dale

 

Hmm I will be running my Microtech on a series 5 jspec motor. Will I need all the clips from the Jspec? Or will the harness come with all the right clips to just plug it in?

 

I started another thread with pics of the hand controller & dash unit.You can check them all out there.
Jon

 

There are a couple of ways you can tackle the wiring on the s5 engine.As the clips for those are totally different to anything else & a bastard to get,it would be easier to use your existing ones or get hold of a engine harness off an import motor and use all those.
Another way some guys do them in Australia is to snip the wires about 6 inches before the factory ecu inside the car & join the Microtech loom in.It's only a matter of getting hold of a mazda diagram & joining the correct wires together.That way no wires need to be touched at all in the engine bay.
The only thing you will need to do in the engine bay is run a vacuum line from the Microtech to a good vacuum source on the intake manifold.
As Dale said,keep firing those questions at us & we'll keep answering them.
Jon

 

The jspec motor I am purchasing should come with a decent harness, if this is the case I should be able to use those clips if I am understanding correctly?

 

rx7_turbo2: You've hit the nail on the head. And if you don't want to reuse old plugs, or have some that are not reuseable, there are other options.

Also, I'd again like to encourage use of the mail list... let's get something going there, lads! (see http://www.team140.net) for details.

Brandon

 

Groovy

Not that it's a big deal, I wouldnt have a problem cutting in existing or new clips anyways. I will try and start using the mail list.

 

if you have any daubts about the harness condition, cut the plugs off and run the new harness, nothing worse than wiring problems, i try to use the new harness where ever possible.

Dale

PS ill sign up to the list as well

 

for the injector plugs, it just hit me that Toyotas (4age, 7mgte, 1j, 2j etc) use the same clips, i remember using some s5 mazda ones on my mates 4age, they may be avaliable from toyota over there at a reasonable price.

Also i like to pull the pin out of the connectors and take the factory wire off and join the new wire right onto the connector, no solder joints! i have a tool made by snap on to remove the pins, best $50 i have ever spent, you can use a ground down screw driver to lift the tab that holds in the pin but the tool is perfect for it, and it has 7 tips for use on differnt plugs,
i try to do as much as i can to minimise the solder joints on the injectors and the ignation setup, a good install makes life a lot easier!!

Hello,

I am in the middle of an RX 2 conversion, and wanted to use the MicroTech.

I have a brand new S4 block with S5 internals. However, I got no sensors at all in the deal ( I was planning on going carby but changed my mind)

So what is the easiest way to get hold of all of the sensors that I would need to run this engine with the MicroTech? Can MicroTech supply? what is the cost?

Thanks

David

 

since it uses all the stock sensors, does that mean that I have to keep my AFM?

 

Jesus
The airflow meter can go straight in the bin!!!!!
The sensors you will need are water,air & TPS.The unit runs an internal map sensor so one wont be required.
I can supply new sensors or you can use factory 13B turbo ones sourced from a salvage yard or importer.
Jon

 

Im thinking of putting a -RE into my TII, tell me more about this harness. Does it make things basically plug n play? One end into the ECU, then plug in the sensors? Do these things use MAP sensor? The CAS wouldnt be a problem if I was using the -RE CAS right? Id also like to know a little more about the difference between the LT-8 and the LTX-8. You guys are quickly convincing me to sell my E6K....
