I've seen a couple ppl on this board mention the ltx8 but in all my searching on the web and in other forums, i have never come across this model, the only model i have seen is the mtx8. Is this a newer model or is this a model for the US? From my understanding they both can be used in conjunction with a laptop now, not just the hand controller, rite? Does the hand controller come with the ecu or is it a separate add-on? I know this is an rx7 board but i am interested in using this standalone for an mr2, does anyone have any experience with this or know someone that does? Also from what ive read, the ecu's come with a basemap preprgrammed so you can atleast drive your car to the dyno to get things fine tuned, do they have base maps ONLY for rx7's or would they also have one for mr2's and other cars. Would it be cheaper to purchase the unit from australia or the usa? What is the best price you've seen this unit sell for? Any other experiences on this product would be greatly appreciated.

dasalnt,
The LTX is a unit developed for the US market and is the latest laptop programmable unit from Microtech. It is very popular in Australia on both Rotary and piston applications. They do come with a base map and can be configured for your MR2 or most other efi applications. I hope this has answered some of your questions.

Hi anythony, thanx 4 the reply. If anyone has answers to my other questions it would be greatly appreciated, thanx!

The MTX8 has been taken over by the LTX8, which is laptop programmable and a few extra features, you can get a MTX8 upgraded to LTX8, for your mr2 you would be better with a LT8, and use your standard toyota igniter and coils, i am tuning a LT8 on a 4age this weekend, i wired it up last weekend and all is looking good.
Yes you can use both the laptop and hand controller, but the laptop opens up better tuning features.
They can supply you with a base map to suit any engine you require,
i dont know where in the USA you would get it from, Anthony might know, but they retail for $1195 for the LT8 in aus, which is about $700 us,

Hi Dale, thanks for the info. Why do you think that the lt8 would be more suitable than the ltx8? Does the lt8 and ltx8 both come with the hand controller or is that a separate option? Do you know what the extra new features are on the ltx8 and lt8 compared to the mtx8? Thanks for your info!

10sec rx7

The difference between the LTX and the LT is the X has built in igniters, and you use 4 coils 1 for each plug, going on the 4age im working on at the moment, the toyotas dont have a true crank angle sensor they still use a dizzy and a external igniter to fire the coil, you would be better using the LT8 and your standard igniter and coil, this setup will work great, 90% of the 4cyl cars here in Aus that use microtechs use a MT8, the LT and LTX are identical computers, just one has ignators and one dosent, they both have the same features.
The LT series has a few extra things, like leading trailing split for a rotor, data logging with the laptop, different way of tuning as well, you use rpm points to tune not load points, you choose the rpm point you are at and can then tune all the load points from 30hg to 20psi in that rpm point, you can also get a 3 bar map sensor and soon there will be boost control.
tomorrow im tuning this 4age so ill let you know how it all goes, we are not sticking it on the dyno yet as it is a new motor just getting it running so we can run it in and then we will hit the dyno.

you mentioned that you can also get a 3 bar map sensor or boost control, does that mean that the standard lt8 unit does not have any boost control? I would have to use another boost controller like an avcr or a mbc? How much do these extra features cost on top of the base price? Thanx and definitely post back on how the 4age install and tune went, im really interested!

10sec rx7

The standard unit does not have boost control, im not sure on the exact price but im guessing around au$300 for the 3bar and boost control.

We got the 4age going today, yesterday we had heaps of problems with a water pump leak, then a timing belt problem, got them fixed today and she started straight up, had a majour vacume leak and was idling at 3500 rpm so tracked it down and fixed it, had to change the cold start settings a bit and the idle maps but she revved clean and sounded sweet,
The new laptop software is great, so easy to use and swap between maps, and with the 3d maps its so easy to use and adjust settings,
we have to fix a few little problems with the fuel system and another water leak this week and we will have it on the road next week for some light tuning.
here are some screen dumps from the software

this is the main screen when you first connect to the ecu

this is the data guages, ie: boost, water temp, a/f, throttle position etc

this is the 3d map, there is no data there as there is no ecu hooked up to my computer but ther lines on the graph move up as you plulse the injectors more

i`m considering Microtech too, but one i found is MT8 i think, where would i find all info about models/what it comes with it, features and prices ?

thanks

Where is the best place to buy the LT8?

fdracer

what's the resolution of the ignition and fuel maps for the LT8?

>i`m considering Microtech too, but one i found is MT8 i ?>think, where would i find all info about models/what it >comes with it, features and prices ?

>thanks

At the moment they dont have a web site, there is some info on www.injectionperfection.com and http://www.rigoliracing.com.au/microtech.htm
the info on there is for the MT8 not the new 3D LT8, but the basics are there, the new LT has rpm maps every 500 rpm with 30ing vac to 20psi in every rpm load point.


>Where is the best place to buy the LT8?

You can buy them direct from microtech in Sydney or through a dealer, im pretty sure MVA are a dealer in the states

>what's the resolution of the ignition and fuel maps for the LT8?

ill try and explain this as best i can,
fuel there is 8 idle load points, and load points every 500 rpm with 30inhg-20psi so you can tune every load point possible, the resoultion is .05ms adjustable,
the ignation there is rpm and load every 500 rpm and is adjustable by 1 degree at a time, eg 27 degrees is too much can bring it down to 26 then 25 etc.

hope this helps.

Looking at price est $1300 AUD shipped for LT8, is that correct ? Whats suppose to come in package and how hard it will be tune it ? (we already did one Haltech E6K install)

I need to get rid of MAF, be able use 1500's injectors in secondaries....

Would it work in TPS/MAP mode ?

10sec rx7

Yep around $1350 shipped with laptop connections (you require a dongle for it to work),
The install is easy, i can do a 13b turbo in a 1st gen in a couple of hours, they use all standard sensors,
Yes you will have to get rid of you air flow meter.
yes you can 1500cc injectors, i run 4x 1200cc on my car no problems at all,
you can choose how you want it work, the base map uses MAP mode.
In the package you get a ECU, Loom, Instructions, and a laptop dongle, and software,
The standard base map will run the car better than the standard computer and make more power than a standard computer.

thanks for your answers ;o)

is that dongle in price, right ? :o)

is it using stock map sensor if it doesn`t come in package with some better ?

10sec rx7

The computer has a inbuilt 2 bar map sensor, you can get a optional 3 bar.
Yep the dongle is in the price, id have to ring up and check on the price for you to be 100% sure

2 bar is how much PSI ? :o)

would it be ok for my hybrid at 12-14 psi max ?

and what about boost control ? i heard haltech's build in one isn`t really best choice, what about in microtech case ? If it has build in how it works and how hard is to set it up and if its like option, how much it cost..

thanks

10sec rx7

24 psi dude,
it will handle the 14psi no worries
ive heard that the boost control works fine, i havent used it so i cant really comment on it.
not sure on the boost control price ill call them tomorrow and get some prices.

RICE RACING

2bar map sensor is a 2 bar Max Absolute Pressure sensor.

Ambient pressure at sea level is 1bar or 14.5psi, a turbo car running 14.5psi "boost" is running 1bar boosted + 1bar "atmospheric" I.E. The MAP sensor will read 2bar.

Therefore a 2bar "MAP" sensor only reads to 1 bar boost pressure. Remeber MAP="mean absolute pressure" I.E. atmospheric + Gauge = MAP

A 2bar gauge sensor would read to 28 odd psi but not a map sensor !

Either you or Microtech do not know what you are talking about, or have made a mistake in the meaning of MAP and are quoting the wrong units in your specifications . Just wanted to clear this up for you guys

10sec rx7

Yes rice i ment 28psi, 2 bar above atmosphere,

yes people do make mestakes when they are busy,

hmm microtech dont know what that are talking about, hmm like to know how you got that off a mestake i made

10sec rx7, i got money for Microtech or Haltech now, what would be reason to go E6K over LT8 ?

10sec rx7

No reason to go E6k over LT8,

the reasons for going LT8,
Ease of install, can be done in a few hours.
Ease of tune, base maps are perfect, you can start and run the car for as long as you want on the base maps, they run consertive timing and a bit rich to be safe.
with a few hours mucking around you will be able to tune your car your self, not have to pay someone to do it,
and they work, and work well,
Go the LTX8 and you have a full direct fire ignation using high energy coils, no more mazda coils, and its only a few extra wires to wire up!

hIGGI

iTrader: (7)

i know price of LT8, but what will be price of LTX8 with new coils ?

i was told numerous times that FC ignition system is really good, why would i go for aftermarket one ?

and in features when u compare LT8 and E6K ?
