Can I "tune" or "map" my stock ECU?

Recommended Posts

I recently purchased my '93 GS 300 and i'm in love with it. The engine was just rebuilt, transmission was just serviced and all fluids are new. The only thing that I really want to change about the car is the fact that it feels so heavy. I live right off of the highway and I feel like it takes way too much to get up to speed. I have been looking at buying a turbo kit for it but is a little out of my price range at the moment. As far as I understand, the ECU needs tuned after installing a turbo kit. For right now i'm wanting to still try and get my car tuned for more power and bring it to life without it costing me an arm and a leg. So, i'm wondering if I need to buy an performance ECU or if i'm able to get my stock one tuned. (I'm new to this, if you couldn't tell)

I think your best bet is to have someone like JET do the work, If I remember right, you send them your ECU, takes like a day, and they tune it for you, you just buy a JET box, they do the programming and it goes back in the car.  Pretty safe I would say. You send it in after you have done your MODS, turbo or anything, think its like 400 bux, 10 to 20HP gains.

      Hi everyone,
      My 1999 Gs (179k) makes this creaking noise when I am turning at low speeds or if I am braking at really low speed like while backing up. It’s also kind of unpredictable. Sometimes it won’t happen, and it’ll go away and then the next time I make the same turn it will happen.  I doesn’t really affect performance at higher speed although above 60 MPH i experience quite a bit of play. 
       
      my Mechanic said I need a full control arm swap and quoted me $1900 for OEM parts. He also said it’s not gonna fall apart anytime soon, but to replace it depending on how much I love the car. (I love her a lot, hence this post) However, I have been reading online a lot about how it could just be one ball joint, so I’m thinking about getting a second opinion. I am also wondering if anyone has any input on whether or not swapping the control arms, all 6 of them, would help reduce the amount of steering play I have. 
       
      Any thoughts on doing aftermarket control arms? Has anyone had a similar experience?
       
      I appreciate any responses:)
       
      thanks,

      We live in the Largo, FL area and I need a good Lexus mechanic to help me solve a problem of my '96 LS400 running very rich. My former Dallas mechanic believes it's the ECU, but I can't get the car back to  him for repair. Any help is greatly appreciated.
