  1. Custom Tune

    I see you're also in NC so what shop was this? Did they also tune it on pump gas/lower e blends? The only thing I could think of is if they just put enough e in it to get to e30 and then diluted with 93, but I don't see why they would

    Trans reliability at higher torque levels isn't relevant when we're talking about the trans?
  3. Haha! C'mon man!

    MT trans holding up to 700+ torque on several cars. How's the auto hold up at that power?

    That's going to be an issue with the dp or o2 sensor. Unrelated to having the jb4 unless you're running ethanol or bad fuel and it's related to the tune not running well
  5. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    Yes, but jb4 did not cause the code. You are just reading the code using jb4. Unless it was caused by a bad tune on the jb4
  6. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    I had a couple of these lately while doing a custom e20 tune, but it was due to my trims being too high which caused it to go into limp. This specific code only came up 2 out of 5 or 6 times it went into limp though. What were you doing when this popped up?
  7. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    Codes are based on the ecu and sensors, so no, jb4 wouldn't cause any codes that you wouldn't have gotten otherwise

  9. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Is the variance in e content from pump e85 enough to warrant any concern?

    It’s kind of odd we can’t delete our own threads lol
  11. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    How safe/consistent is blending ethanol yourself for map 2 & 4 without using a flex fuel kit? I plan to go PI/visconti reflex in the near future but I would like to run some ethanol in the interim with the jb4 I already have. I don’t think a flex fuel kit would be worth it since at a minimum I’d...

  13. Heated the trunk a bit too much.

    Paint fades from things like sunlight exposure. If anything, the paint under the spoiler will look newer than the rest of the paint

    Right, but it still blows stock turbos. Get a custom tune before you start running e on map3 also map4 is e30 with absolute target of 20 instead of map 3’s additive 6lbs

    Map 3 is known to blow the stock turbo. Be careful
  16. A compact air blower for drying your car

    I use this and I’d recommend it: https://a.co/d/guaHBnd The only downside is the battery life. Usually dead after one use but it’s better than the alternatives I’ve used. Use a squeegee for the glass though
  17. (US Owners) Do you receive automatic navigation/map updates?

    I remember reading that Toyota will report your driving habits to insurance providers if you use their app so I’ve steered clear of it. If the only downside of not being enrolled is the lack of automatic nav updates then I can live with it
