I'm totally new to tuning. I have EFI Live with FSV2 that I purchased about 7 years ago and used to flash my LS1B with a mail order tune. I have built a new motor for my car that is going to be installed in the next few weeks. I have read a ton on this site, but I'm unsure about so much still it is kind of discouraging. This is the 1st of about a million questions to come. I want to get some opinions about which WB02 will work the best with my LS1B. I have read that there is a limitation to how fast I can log with the LS1B compared to newer ECM's that run on the CAN bus. I have been looking hard at the AEM 30-0300 and the Ballenger AFR500v2 with a NTK production or calibration grade sensor. Would I be able to take advantage of the AEM's speed ? I've read that the analog output on it is actually very good. Is there any advantage to the NTK sensors over the Bosch 4.9 LSU ? Thanks in advance for any response to my questions.
