With all this trying have you changed things and they have not fixed the problem and you have not put them back? (like sensor set up, sensor wiring, timing, fuel trim, etc.)
are all the sensors reading corectly?
TPS, MAP, Air Temp, Water Temp,
Do you have fuel pressure at the injectors?
Do you have SPARK?
Make sure the plugs are not fowled from trying to start. (change the plugs)

yes all other sensors are reading correctly. new plugs, everything thing back in place just not recieving a signal. once again i didnt think injectors or coil would pulsate without a signal.

but if the orange light is flashing when cranking it is recieving a signal... just not the right one hence the reasoning behind swapping the trigger wires around

the orange light is intermittent just like the recieving signal. with everything connected except the fuel pump power(dont want to flood the engine) for every 20 cranks you will recieve a signal mabye four times. this means crank 5 sec's and wait 5 sec's. 20 times. looking at the laptop's rpm guage in the upper right corner while the owner is in the car looking at the orange light. the four or 5 times i get an rpm reading out of 20 cranks on the lap top he will se the orange light pulse inside. they correspond exactly everytime. i went out this morning(23deg out) and reversed the polarity and found the same results.at this point i am more interested in the pin out. if microtech said it's ok i will believe them because i sent them an ecu not the entire harness and car. i am starting to wonder of the pin location in the four way connector is correct. they dont give numbers to location so 10 sec. rx7 can you help me identify the pin location for the trigger input. i know a lot of people do stupid things, i have been there my self. i wired the car according to the manual, had the owner check it over before covering it in loom. and had another person i work with to also look it over. this does'nt mean **** to some people but i will tell you a little on myself. i am a diesel tech 11 yrs. this year for detroit diesel(yes ddc uses a gt42 turbo) i have done repowers( taking cats out putting ddc in. i won the series 60 challenge 2 yrs in a row. (electronic troubleshoothing) s60 is the leading on the road truck engine. ddc was the first company to put electronics on a heavy duty truck engine. i make wiring repairs in trucks every day. srs,trs,vss,opt idle,cruise,jake brakes,injectors etc. in all trucks. i dont claim to be an expert through all this because i still after 11 yrs. learn everyday just like every one else in the world. but i am just letting you all know i am not a novice. with all this being said i cant get a simple car started.(what a dumb *** right). you guys help is very appreciated and i will continue until the problem is found. by the way this is my fourth microtech install, 1st on an fd and of course my e11 install on my fd. thanks again. now can anyone help with this pin out!

the pin out digrame is on the bottom over the wiring digrame, if it is not on yours you can download a manual from www.microtechefi.com that will have the pinout on it

good news. i was able to bring a sensor simulator home from work. i will be able to simulate the cas and really get down to the problem. i will keep you all posted.

well sadly the sensor simulator showed the same results. we also had a guy from mazcare come by and take a look. still same problems. so now it is for sale. lt 10s with ign box still under warranty. the owner is willing to take a loss and get rid of it. best offer please. it is 3 weeks old and purchased from a-spec.

dude do you got the complete harness installed? I mean everything grounded and connected like the X4 box, coils, fuel pump, etc... get everything connected and soldered in and try again

well i had a interesting conversation with Maria from Microtech regarding your problems, this is what they did when the ecu arrived here,
1, ran up on test bench and worked perfectly,
2, pulled apart and inspected the board, nothing wrong so put it back together.
3, PUT INTO A CAR AND RAN THE CAR ON IT!!!!
so there is nothing wrong with the ecu, it is in your install, something is not correct somewhere.

with A-spec telling they can't swap ecu's with me and microtech saying the ecu is ok-but nothing is working out- ur the only one that's trying so thanks man! can you tell me what other factors can contribute to my ecu not receiving a signal. we've got dozens of testing equipment, we test the sensor-its fine a signal everytime, once plug in no action-maybe the setup is wrong u think? if so can provide?

i have done a heap of LT10 stuff and never had a problem with them,
only thing that will stop it starting is something stupid like the wires to the CAS are not correct, or someone has changed something in the software like the number of cyl's is not set to 4 or something silly like that,
try every combonation possible for the cas wiring, you will see on the plug the 2 bottom wires are the signal wires so dont hook them up to the same sensor or it will definatly not work,
i have had 1 problem in the past (on a LT8) where 1 of the wires wasnt earthing properly, take a picture of the 4 pin plug that goes into the ecu, i want to see the side where the wires go into,

1. are you sure your pink wire is not cutting out (12V+) make sure the green light on the ecu is solid as youre cranking. if not jump the pink wire to the Red constant wire for testing purposes
2. you stated everything is connected... i assume you have the fuel pump connected and the coils are giving out visable spark? (test mode)
