ECU help lq4/ls1 So I have a question about ECU for an LQ4. I have an LQ4 from a 2004. I thought it was in 2000, so I had the ECO Flashed for 2000 with only missions taken off.
I question as I know the math sensor for a 2000 is a 3 wire, And for the 2004 is a 5 wire. Since my ECU is flashed for the 3 wire math will I need to have a reflashed for a 2004? The engine does run strong and seems like it has really good power, but I'm unsure. ECU is a 411
