Hi all
Have a 4b11 motor Running e25 fuel and it will go to above 30 ° spark when not in wot , however, as soon as you go WOT it refuses to go past 30° . Anyone seen anything like this before?
Your question isn't clear -- what ECU are you using to tune? Are you saying that if you command a 32* spark advance, the ECU will only use 30 deg? How are you determining this -- data logging, using a timing light?
There are upper and lower bound ignition timing maps in ECU for that engine. You need to doublecheck that the upper limit isn't set for 30 degrees.
Thank you
