I have a microtec ltx 8 for a fd3s. The Ltx 8 that i have is the one that came with out the map sensor build in. I can't figuered out witch wire go to the map sensor and the tps? I have the diagram from microtech.com but is the one that come with the vacum build in on it so it don't show what i need

 

First you need to get a smaller font size

The map sensor in the LTx8 has a vacuum nipple on it. It is not for any wire. Run a vacuum hose from the LTx8 to a vacuum source in the intake manifold. The wires that go to the TPS sensor are marked in the wiring diagram.

Be sure of things and take your time with this install. There are so many things that can go wrong with splicing so many wires into stock connectors, and if you make a mistake you'll be troubleshooting for weeks. I had to build my own wiring harness for mine, and to get it all connected and figured out took nearly 10 months.

Good luck, your gonna need it.

 

well the ltx-8 that i have i guess it was the first that came out because it doesn't vacuum nipple on it, thats my problem. so im trying to get the old wiring diagram or if some one could help me out. Thanks

 

Reallllllllllllly?

I've not heard of that yet. Pics?

My understanding is that the LTx8 is basically an LT8 with an internal ignition coil. The LT8 came out first and that too had a vacuum nipple for the internal MAP sensor. Where did you get your unit? if it is used it could be that some monkey broke the nipple off.

Edit: This is some serious stuff for the new members section. You should check the standalone EMS section of the forum.

 

im have to look at that. I did open the ecu to see the inside and everything look find, it seen nothing has been broking or missing. I e-mail microtech a few time but they haven't e-mail me back. But thanks a lot for your information

 

map sensor just connected to the stock location by the firewall. Then the TPS connection you have blue,grey and brown. blue is for +5V and grey return signal and brown is ground. connect LTX brn to TPS BRW/BLK, then GREY to GRN/BLK and BLUE to BRW/WHT. The GRN/RED doesnt connect to anything. i hope this help.

 

Thanks it does help me a lot now. one last question so i don't have to connect the factory map sensor to the microtech?

 

1993 rx7 Im trying to use the factory Map sensor to my microtech just to start the car but i can't figuer out what cable is what in the map sensor plug?
