AE101 SEG 4AG Blacktop 20V + Microtech LT10S

New project already begun,a friend and regular customer at Garage Daz decided he needs something different than the ordinary for his 4AG Blacktop management systems, and suddenly he bought a used Microtech LT10S, and it is not even for 4AG model, it was on Nissan SR16 previously! And now it is my job to make it run on the 4AG 20V.

All Microtech ECU is engine specific,which means it is only can be used on the engine it was programed for. The crank trigger setting is not accessible for users to change, this restriction do have an advantage and disadvantage. The advantage is easier first time start up, which user or tuner doesn't have to spend his time find the correct ignition timing for the engine. All Microtech ECU will fire up at 1st crank on the engine its programmed for if all the wiring are done correctly. The disadvantage is,it is hardly transferable to any other engine. It is not universal like Haltech/Motec/Autronic..etc

So,can we make it run on other engine? Yes we could, the trick is to run all the sensors from that particular engine it is programmed for. In this case, we need to use all SR16 sensors on the 4AG engine. This will involve custom work to fit the sensors on the 4AG, most importantly is the Crank angle sensor (or usually called Trigger in engine management terms).

The owner opt for plug and play wiring to ease installation and reduce downtime, hence a used ecu connector is sourced to make the plug and play harness.

Connector to plug in on the stock 20V wiring loom was sourced from a burnt ECU.

 The connector which will be plug onto the stock wire harness,the other end will be plugged to the Microtech. Shown here is the finished connection without the hot melt glue. The harness will be tested and will be hot glued later to make sure every pin does not move, this is to ensure reliability as it will vibrates when the car is moving.

The car now is waiting for internal surgery on the engine,so i guess i wont be updating this story real soon, but stay tuned for updates in a few weeks time.
