Ok... so I'm a retard, but I figured I'd ask...

1) Does the LT-8 support an OMP, or will I need to go S4 Mechanical?

2) No matter what, I'd need to order the "FC Model", meaning I couldn't swap it to another non-rotary powered car.

3) Is this system REALLY plug'n'play? All haresses plug in like stock?

4) To double check, the unit comes w/ a slightly modified FC map on it already, so no tuning is needed... until I want to do it?

If anyone wants to include some links to any LT-8 or LTX-8 informantion (I've not been able to find and good info) please do. Also if there are any other issues w/ installing it on an 89 GTU, let me know. THX

 

1. No OMP control, S4 mechanical is the alternative without pre-mix.
2. No you cannot swap between different ignition pick up types.
3. There are plug'n'plays for FC or FD but the LT series are not really a plug and play as known in the USA.
4. Microtech has a huge library of fuel and ignition maps for most popular import type engines.
**We usually overwire into 89 rx7 and continue to use the factory idle/OMP/ac controls. I could supply you details if interested. Hope this has helped

Anthony,

My largest question on the MT is AC. Will I need to retain the stock ECU for AC control? Or i can I run the BAC valve with the MT's PWM output?

Daniel

 

No, only the Purple Motor Eater supports the OMP, but it drives it at 50% all the time, which is decided suboptimal. Either mechanical or premix is the only way to go.

Since it uses the stock sensors (including the CAS), it's got to stay with the FC. There's a slim chance you could have the unit reprogrammed for a different set of sensors for a cost, but I don't know for sure.

The LT8 uses all the stock temp, CAS, etc sensors. It comes with a flying lead harness which replaces the stock harness completely (with much higher quality wire, I'd hope ). It's plug 'n play insofar as you don't have to retap all your sensor holes, etc to use new sensors, but it's not a piggyback in any sense.

There are many maps available - let me know your setup when the final GB time comes, and I'll get you one to fit.

Check out http://www.team140.net, and follow the link into the GB, then onto the specs for all the info you could ever want.

No and yes. The stock PWM output supports idle air control solenoids, which is enough for the A/C's load. The only connection between the A/C system and the ECU are two signals that let the A/C system know that the engine's WOT, and lets the ECU know that the A/C's on.

I'm new to the MTech, and am just wondering the steps to go from stock ECU in the car w/ working sub-systems (OMP, VDI&5/6th ports working off their stock signal) to Standalone, w/ the same working sub-systems.

It seems I'd need to buy a couple RPM switches to actuate my 5/6th ports and VDI (no big deal there, that's just more HP by fine-tuning them) and convert to a S4 front cover, for the mechanical OMP. Then DL the stock or similar maps... Then my car will be very close to how it is now, correct?

*sorry if this seems blotchy, I started writing it 30 minutes ago, then had some distractions*

 

Oh yeah, about the BAC! Would it need to be removed? Or will it be supported? (Wasn't too sure w/ your last comment)

If someone who knows a lot about this wants to IM: AgeOfGlow, I could keep my post count below 1400

 

Wow, an N/A guy... We don't get many of those around these parts...

It sounds like you've got it pretty much down. IIRC, the LT8 can use the binary output as an RPM switch, so you could use it to control your VDI or 6PI, instead of the termofan or nitrous. I honestly don't know about stock maps, since I don't think there were any N/A 13Bs in Oz, but I'd imagine a 13BT map should work fine... they're all the same under atmo anyway, right?

Brandon

 

Yes, the LT8 has a PWM (pulse width modulation) output that will control the BAC.

Brandon

 

I'd rather keep a standalone 5/6th Port and VDI actuation method. I plan to use the variable output to either run my thermofan (probably not) or to work with my nitrous setup (down the road).

I could probably get the needed maps for E-Manage, and convert them. I know there are people in the US w/ E-Manages on N/A's they're just few and far between.

 

HEY! I know that I don't post all that much in here, but I'm an n/a guy and I've been shouting about MT for the better half of a year! Just kidding, of course.

On a more serious note, my MT and I get along better than I have with any other piece of machinery I've ever touched. A great system with friendly people (all in Australia, but that's why we have email and the Forum) to support it. Get it and you won't be sorry.

 

Hey guys.
OMP control is well under way & should be finished & running on the LT & LTX in about 2 months.
Jon

 

will it be in time for the group buy?

 

ok im NOT a computer person so TALK TO ME on all this stuff. im doing a sr 4 block with sr5 turbo/to4 setup on a ported motor...front mount and -se injectors in my 83. i have a wiring harness and all the stuff but this will give me way more potental and i think it will be much eazyer to hook up. the big things i have to ask are stuff like can i remove all the smog crap and still run this ecu off a min. amount of vac boxs? how hard is this to program? i to am on the g.b...well when i get the goahead you can do it its eazy part verified, then ill pony up the $$ i just dont want to get in over my head with a standalone. i mean i hear all this stuff about open loop, closed loop...whats all that mean? is 1 better? can this ecu handle adding extra injectors? talk to me like im stupid...after all i am when it comes to ecu's

 

Also, w/ this unit installed do the warning lights work? Or would you need to get their dash unit?

 

Hey mate will try and answer your questions for you,

Yes you can remove every piece of smog crap, everything, the microtech requires nothing at all, it uses its own map sensor to sence the engine load, you no longer will require your air flow meter either. No vac boxes required either.
they are very simple to programe, easy to follow instructions that tell you what all the features do, if you have a basic understanding how a engine works and have something to check the A/F ratios with you shouldnt have a problem

open and closed loop are the way the ECU runs the cruse, with a well tuned sysem running open loop will give the same if not better fuel economy

yes you can run up to 16 injectors on the LT/LTX8 and 24 injectors on a LT/LTX12, they will run both high impedence and low impedence injectors with out any mods to the ECU.
