R33 GTR- Check engine light flashing under acceleration

Postby dakr33gtr » Thu May 25, 2017 10:37 pm

Hi,
I recently did some upgrades to my R33 GTR and put a different tune on the ecu. I just took it down the road real quick and noticed the check engine light started flashing during acceleration. Once I got back to the house I tried reving the engine to see if it would come back on and if I rev it in the higher rpm's the check engine light flashes. What could be causing this? any information on this would be greatly appreciated.
Thanks

If you have the CEL set to indicate knock, then you are getting a knock detection light with the new tune you loaded.
