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

    It’s insane to me that my mindless mistake led to this… Let me know what sensor you want me to disconnect next and I’ll give it a shot ?
  2. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Pushing the JB4 MT tuning to new heights with O2-less tuning? Was my plan all along :cool: Here’s a run on V24 with your suggested settings: https://datazap.me/u/a90omen/log-1729276349?log=0&data=1-4 I only ran ~500mi without the O2 and had the JB4 gauge view up every ride watching AFR and...
  3. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    I installed the pre-cat O2, post-cat O2 still uninstalled (let me know if this should change). I thought with the catless DP the O2 readings don't matter since it will throw a code regardless so I left them on my old DP since I wasn't using any O2 spacers. What really convinced me is my DP came...

    I am sure, I wave at it every time I pass by my DP in the garage /s It's getting put back in as we speak.
  5. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Looking back, all of my logs are at 25... The only reason I can think of is because both of my O2 sensors are disconnected, could this be it? Or is there a loose JB4 connection somewhere and I shouldn't need to reinstall an O2 sensor with my catless DP?
  6. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Yep a MT CU Later grey! I’ll drop FF by 2, but where exactly should I raise boost and by how much? I’m running that map 6 you sent that I quoted above so I’m not sure what “add more boost” is. I’ll see if the trims fix themselves on the next log but I was wondering if it was my E mix that was...

    Hey @ColonelAdama, back again with another log. I used your Map 6 settings with my stock cat back and things felt good. I then installed an SP1R and the logs didn’t feel too different but I always meant to come back and check in again. I recently took a log, and while low on gas I threw in some...
  8. Getting Ready To Sell My 23 MT

    I ended up buying his SP1R and can vouch that he is great to work with. Super flexible, responsive, and no complaints through the whole process. If you’re looking to buy any of his parts, or his car, I am proof that he is in fact a real person and I highly recommend working with him. On a side...

    @ColonelAdama If you could spare some time, this time Map 2 with your (found somewhere in this thread) updated duty bias settings for catless MT cars. Did a bit of idling at the end too just to get a better picture of how the car behaves on Map 2...
  10. Getting Ready To Sell My 23 MT

    I’m in Indiana and very interested in your SP1R if not already sold. I have stock exhaust and diffuser I can throw in with cash so you can revert back to stock. I sent a DM but feel free to hit me up on instagram @a90.Omen
  11. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Hey Colonel, mind checking out my logs for my 23 MT with CTS Catless downpipe? I've been stalking this and many other of your threads where you are helping others so I know enough to be dangerous, but not enough to be accurate... I did a stock JB4 settings pull on Map 1 with everything else at...
