This page contains all test of the new Subaru Trigger code
24/5-2010
What we have seen today.
We have stable 160 rpm at cranking fuel pump off.
When we cranking the car it´s stable in beginning it fires up to 300-600 rpm then random fires and rpm¨s no longer stable.
Its like it runs only on two cylinders (firing correct) but then lousing sync
We see some correct firing´s but also ignition fires two wary short times when it should not.
Question: Haw is this code tested and what signal is used?
It is wary important when testing that we have a swinging signal like 100-300-120-500-200 rpm`s and not lousing sync. Not joust a long stable sweep
We have big trouble scooping the output of LM1815 because of the short signal like 15 micro sec.
I would suggests that we use the p259 led´s output. When the processor get signal from lm1815 Pre/sec trigger we set the output high for 0.5 sec. This will give us a chance to see and measure what goes in and out of lm1815.
Any suggestions are welcome
