VE Swap ? about ECU
I have a 91 SE-R that im swappin in a VE motor. I have read about 99% of all the info i can find on the forum about this swap and i feel like im sucking on a firehose. My question is do i need to upgrade the ECU if im installing a MSD 8969 (orderd and otw) switch for the VVL or can i use the ECU (the motor i ordered came with the VE ECU and wiring harness) or do i also need to upgrade/tune/change it. I have also ordered SSAC headers/downpipe and the Dayco hose as well so far. Appreciate any advise or direction.
