I have a series 4 n/a 13B in an 84 body. I am now having trouble with the wiring (go figure). A rotary mechanic I trust told me today to look into getting an EMS. He suggested microtech but also gave the impression it was really up to me. I'm not making huge power out of this engine and intend to keep in n/a. What would be a good EMS to run? I'd like to keep the price somewhat low while ensuring everything works correctly. Thanks guys.

 

Carby Bridgy!!!

 

Hehe, I've thought about going carb, believe me. But I don't know enough about carbs and prefer the idea of injection.

 

Carbs suck! (literally, lol)

I think that Microtech and Haltech are your only low-price options. Also, you may be able to find a Wolf3D 3.x for a good price now that the 4.0 is out. However, if your tuner likes the Microtech, then that's probably the way to go.

 

Okay, I've spent the last couple hours reading just about everything I could find on the Microtech system. I like what I've read so far, sounds like what I want and not too expensive. Installation and tuning seems fairly straightforward as well.

What exactly is necessary in order to install this system on my engine (n/a 13B)?

 

Need to know weather you are using the crank angle sensor or a Dizzy,
if you are using the dizzy you can get a LT-4 fuel only, will cost you about the $400us mark, same as a LT8 just with no ignation outputs.
if you are using the crank angle sensor get a LT-8 or LTX-8, the LT uses the factory coils and the LTX uses bosch coils and direct ignation, i would go the LTX much better Ignation,
Either of these 3 computers will use all the factory sensors (Water, Air, Crank/dizzy,TPS) and will allow you to remove the air flow meter as it has a inbuilt map sensor.
so all you will need is a Computer, they come with a flying loom and just fit your plugs to the end, will take about 3 hours to fully wire up.
the N/a 13b will use the same computer as a 13bt as im 99% sure the crank angle sensor is the same, if you are going to tune your self you can use the handset or laptop if you have one, for the laptop you will need a dongle to connect it.

 

Wow, sounds so freaking easy.

I'll likely stick with the stock CAS. Not sure about switching the coils since I'd like to keep it relatively cheap and I'm not making the kind of power where it's necessary. Is it possible to upgrade to the better coils later on?

Thanks for your help on this, BTW. I really appreciate it.

 

The price difference between the stock coils and the bosch ones will be about $150us, the stock coils work fine for 10sec passes so just get a LT-8, it will run fine off your stock crank sensor and stock coils and all sensors,

you can change over at a later date b1ut you would be better to go to like a MSD DIS-4 to run them.

they are very easy to install and will run with the base maps very very well, the cold start will be way rich i would suggest to pull about 20% fuel out of the lower temp maps before evern trying to start it, i have found that +10-15% fuel for the really cold maps work well, anything more and you will have to hold the throttle and they will be hard to start,

if you are installing make sure the wires in your crank sensor are not broken or frayed, if they are run new wires all the way into the sensor, also the shelding on the crank pickup wire should be earthed.

Cool, sounds like I'm gonna get the LT-8 and the 4 line handset. My mechanic is looking into becoming a distributor for them, so I'll likely get it that way. Pretty sweet, he's almost as excited as I am about this.

@10sec rx7 - Would you mind if, when I get my equipment, I contacted you with any questions I have about setting it up? I don't think I'll have any major issues, but may have a few troubles that I can't figure out.

 

Dude,
do you have a lap top?? if so get the dongle to tune it with the laptop, the handsets are very very hard to tune the 3d computers with, my laptop went flat half way through doing a mates car and it was very very hard to do so we just went home and charged the laptop,

instead of the handset get the dash board, you then have 4 light shift light, bar tach, boost reading, water temp, warning lights, its a very good unit, and you can use to do tuning adjustments but its not as easy,

here are some screen dumps of the software



By all means contact me,

email dheiler@toshiba-tap.com

If you follow the instructions you will have no problems, read it cover to cover a few times and you will learn what everything on the ECU does,


Dale

 

Sounds like a good idea. What level of laptop is necessary to run that software? It looks fairly straightforward and simple, but 3D mapping may take a bit. I'm willing to dump some cash into something that I could use for school and to tune my car, but not too much cash (strictly word processing and tuning).

What is this dashboard you speak of? I've read nothing about it, but I like the way it sounds. Any sites out there with info (I've seen three sites, all of which still had the MT series, not the LT)?

Softward looks great and like a decent investment.

 

i run the software on a Pentium 200 with win95 and it runs fine,

ill try and dig up some info on the dash boards, i have to go to Microtech and get a old computer i have upgraded at lunch so ill get some info on them while im there

 

Went to microtech at lunch time, and they are going to send me the latest info on the dash by the end of the week (still at the printers) ill scan it in and give you the link to the page as soon as its ready.

Dale

 

Sweet, thanks man.

 

anytime dude,
i have a wiring digramme on my pc at home to, ill throw it up on the web so you can see how the LTX-8 wires up, its very simple and you should have no problems doing it,

Dale

 

Hmmm, trying to contact Dalton Automotive in Australia and having a hard time. Is the number (03) 52242708?

 

Yep thats the number,

dial 61352242708

or contact microtech direct on

61298085233

i got the info on the dash lat night, ill scan it in tonight for you, there are no pics unfortunatly, im pretty sure there are cars on fullboost.com with the dash in them.

 

Got a hold of them eventually. Man, international calls are confusing And then you Aussies speak with that accent . It's all good, the order's going in tomorrow. I'll likely get the dash based on your description, but it'd be cool to know the specifics before I order. If you don't get a chance to scan it in, no worries.

 

Here is a pic of the dash

 

Oooh, that'd look good in my interior. I may have to get it. I'll let you know later today exactly what I end up ordering.

BTW, the stock sensors I need to run are the CAS, air temp, and water thermo right? Where is the water thermo sensor? I have a small fear I may have taken it out when I installed my autometers.

EDIT: And the TPS of course

 

the water temp sensor on my motor is on the back of the water pump, it has a injector plug on it as well and is green in colour,

yes you use the factory tps as well

Dale

 

Cool, I have all the sensors I need then.

I, along with another guy in the area, ordered the system last night from Dalton (I couldn't get through to Microtech when I tried). I got the system, software, dongle, and 4 line handset. I passed on the dash for now, maybe in the future. Decided to get the handset since I'd like to be able to leave the laptop at home once in awhile .

Thanks again for all your help. I'm sure we'll have some questions when we're installing them, so stay tuned.

 

Sweet, the handset is not much good for tuning in matrix mode (3D) it is really only good for checking data logs and stuff, it just cant display enough data on the screen at one time, but good to have to check things,

 

i'm gonna try and bring this thread back here-a question about the different ignition systems-would a LT-8 with a msd-4 actually result in a better system?end all,it would come out to the same price,and i would think the bosch coils would be more powerfull..but is the direct ignition on the microtech as good as the msd-4?

 

A single MSD DIS-4 CANNOT work on a 13B rotary.
