I don't have an answer to that question. I hate abs with a passion so I would be happy to lose it lol. I don't know why everyone that does an ls swap wants an aftermarket computer. An 0411 or p59 can be tuned with a $100 or under dongle and free software. The aftermarket computers leave **** on the table as far as tuning. Yes they do it themselves but are far from perfect. L31maxexpress has just been there. I guess no one wants to take the time or effort to tune
