so m asking way in advance because I want to know as much as I can before I go ahead and jump the gun. I've tried doing all the research I can on google and clublexus but haven't found anything.
so heres my question, I have a naturally aspirated 2jz 1992 sc300. I want to buy the haltech platinum sport 2000, or ps2000 for short. I know its a way overpriced/ overated ecu for a naturally aspirated and I know the ecu is overpowered for my power goals. but I want it. so don't tell me to get a different one please. I know the gte ecu would work with my goals or aem would work for cheaper but I have had a desire for haltech since I first heard of them.
now from what I understand, I have to buy a map sensor to make the ecu run, but its also better to run it on wideband o2 sensors (at least that's what the haltech guy told me). so I plan on buying a map sensor plus the connector from driftmotion. also 2 wideband o2 sensors (specifically bosch lsu 4.2) since my headers still have factory o2 sensor. I would need 2.
anyways, is there anything else that's required, or makes it easier to install?
my specific goal is to go haltech, tune it to my car. then go ffim + tune. then go na-t + tune. I would like to have 600 - 700 horsepower as a maximum daily driven. I have no idea how much psi I would want to push just yet.
back on track, I know enough about wiring to connect it myself. so i'm not worried about someone installing it. i'm mostly worried about someone tuning it, considering it can run upwards of 500$ from what I hear.
so anything else to worry about or prepare for?
