Spartan 2 OEM questions

[Ced Dieu]

Hello,

I connected my device on my ECU and I have 2 questions:

- The LSU warms up but the LED blinks (1Hz ?) at start up she is OFF.

Is it normal ? (the LSU was not in the exhaust during this test)

I read that normaly she is ON when the temp is OK.

- I can not see the sequencing (1.666 and 3.333 V)

It seems that the controler works, when I start my engine, the value goes to 14.7 AFR at idle. (The LED is always blinking, my EGT is 450°@ the turbo entry and the LSU is 30cm behind)

Now, can I believe this AFR value ?

What can I measure more ?

Thanks
