Thanks for clearing that up. The purpose for the question is two-fold. First, I'd like to learn more about how my car operates. Second, I wouldn't might saving the $50-75 for a BCC, $275 for a fields replica harness, and the time it takes to tune/install the BCC. This being said, I'm not about to do anything to my car that could potentially cause harm or does not have a track record of success. The thread about the pressure sensor made it seem like quite a few members had tried this and I wanted to get some input about its reliability/track record. Trust me, I'm not going to use my car as an experiment!Nick 95 6sp said:the link in the very first post says it's for cars equipped with a MAP sensor. The stock MkIV uses a MAF sensor.
I don't get it ...are you trying to save $50 on an experiment that could damage or hurt your Supra or has no proven track record of even working?
No worries.Nick 95 6sp said:I agree it's always better to question and understand, not just go along like the blind leading the blind. My comment about saving money came across sounding more narrow minded than I intended.
Says it only works on MAP sensored vehicles. MKIV's are MAF equipped.Chris99 said:
I would like to see some documentation or a letter from Toyota or Toyota engineers which state this. I'm not just gonna trust what Jason S. says without some proof.Chris99 said:Jason S. apparently verified with toyota powertrain engineers that the mkiv boost pressure sensor is only used to initiate fuel cut. It does not affect stock twin sequential operation or fuel pump voltage as claimed in the mkiv.com faq's. He says to just unplug the sensor and save your money on either bcc or fcd. BLKMGK verified that his car used to be that way when he bought it, and sequential turbo operated fine and fuel ran rich on the dyno.
Ok ignore this stupid statement. I need to read the entire thread before I post lol. Seems MKIV's do have a MAP sensor after all. I never realized this, thanks for pointing this out, assuming of course that you're correct.KevinB6876 said:Says it only works on MAP sensored vehicles. MKIV's are MAF equipped.
