    My lexus broke down about a month ago. Took it to the mechanic, at first was the alternator. Replaced it. Car still didn't start. Electrician came by checking all the wirings, scanned the car, found the problem was the ECU. I went to repair my ecu, turns out it had previously been messed with...

    Hey guys. I’d say I’m new here but I’ve been reading through the forums for about a year now but I just made an account since I’d like advice from people in similar situations. I just purchased a turbo kit and am ordering supporting mods, my end goal is ~1000hp but until I get my stock GE fully...

    Hello! So I recently bought an 01 is300 that came with a 5 speed transmission, I was doing research on it and saw that the 01 is300 did not come in manual transmission. So I saw that when you need to do a manual swap you need to change your wiring harness since the 01 is diff from 02-05, so if...

    Hey folks, I have a 99 automatic altezza modelista that supposedly has a cooked ecu. For the life of me those who ive spoken to or sort help from don't seem to be able to help or know much. Plus getting my hands on the correct ecu to replace it is another story. Currently the car does not want...

However, I am worried about running into ECU trouble and would like to find any standalones that may help me out. One of my worries is going to be rev hanging which automatics tend...

    What’s up fellas I got a ‘03 is300 and like many I plan to turbo it in the near future, however I own a turbocharged car but I’ve never turboed an na car before so I’m trying to figure out the best route for tuning. Are there any good standalone ECUs out there for under $1k that I can plug in...

    Hi. I'm Daniel, I'm working on an IS300 related project and just wondered... will anybody care? What I'm making is a device that will hook up a standalone ECU (Ecumaster Black in my case) with all the convenient bells and whistles that AFAIK would require a parallel harness and running both...

    Trying to wire in a TACH out of my SXE10 3SGE ECU. To my understanding pin D26 is the TACH output pin. I can put a multimeeter on it, set to AC, and i get a constant 14.4V. When revving the engine I see no change in Voltage. Is the ECU pin dead? Am I missing something?
  15. Altezza Owner's Forum
    Hey all, working to wire up the ECU for a 3SGE out of an Altezza. The ECU number is 89661-53070. Does anyone have a pin/wiring diagram for this? Had little luck searching online.

    I don’t know much about car computers but I just put the cxracing turbo kit in my Lexus IS300 (2jz-ge) and now I need help tuning it. Can I just tow or drive it to a dyno tuning place and they tune it up and it’s all good or do I have to buy a new ecu, chip, piggyback or something. Sorry if it...

    I want to boost my IS and have seen a bunch of people running the stock ecu. I'm not willing to take the risk I'm too worried about leaning out, and the car will overall be a lot better with a stand alone or piggy back. I don't want to break the bank but I will if I have to. Anyways what is the...
