I have is250 2007 2JZ swap. I have to keep using the previous ecu (is250 ecu) in order to operate all chassis functions by sharing the trigger signal. My problem is that after first start I was revving the engine to check if everything is ok. I have noticed that p1301 code if I exceed 5000 rpm. What is the issue?? I have adjusted my trigger arming voltage tablet with both high and low numbers, but still problem is not solved. Also, I have tested many filter levels. I enabled trigger ground reference. Lastly, I changed the crank sensor and nothing has changed. Can you help me please?
