  1. GR Supra 101: Routes to big power

    Congrats on the car. Most Definity AA dp with a full catback will get you some good power. You can pair it up with a JB4 and a custom tune from @Jesse DaBears if you want to. Smoother ride with more power. After a while you can go with an unlock with bm3 or mhd. Good luck.

  2. Jb4 custom tuning: an honest discussion.

    Is it possible you can take a loom at my logs and see if I would need custom tune? Very new to this forum, if there is a thread for this please point me to it. Please l

  3. Jb4 custom tuning: an honest discussion.

    There is an ass for every seat, same way there is an application for JB4 and custom tuning and unlocks, Ive said this before, from a purely financial standpoint if you are buying everything new, the difference is sub $500 to go from a Jb4 with custom tune to a real flash on a bm3 OTS, but again...

  4. Jb4 custom tuning: an honest discussion.

    First person I've heard say that, but I'm not terribly surprised. JB4 is very fuel limited <4k rpm. Factory fuel tables are not generous enough and STFTs aren't enough to compensate for high boost targets, hence lower torque. 5k+ rpm - doesn't seem to be fuel limited, I can have the JB4 push...

  5. Jb4 custom tuning: an honest discussion.

    As a former JB4 user and Jesse customer. I was pretty satisfied with it. OTS was totally fine, but Jesse really smoothed it out and made it feel more natural. Don't worry too much about peak numbers. I ended up doing the finland unlock route and bm3. It's a little bit more smoother and feels...

  6. Jb4 custom tuning: an honest discussion.

    I still see Jesse's price at 575, but honestly you can just get a secondhand JB4 here for $400 and run an OTS map... Or post the logs in my thread, or on the JB4 forum for review to see if custom tuning is needed. Its not required to get a Jesse tune... He can charge what he does because...

  7. What did you do to your Supra today?

    Any reason why the pull was done in 5th gear? I thought the 1 to 1 ratio for the ZF is 6th.

  8. What did you do to your Supra today?

    Nice. Very similar to mine. He is running less boost but more timing, which makes sense on the lower compression 21+. Plus, I also asked for less timing because track use. I peak at 14*. Usually 1* of timing is about 10whp. I dunno about a dynojet reading "low", It's a dynojet on STD...

  9. What did you do to your Supra today?

    Still waiting on one chart but wanted to get this out. To recap and keep everything in one place, I’m adding content from a few other posts of mine. I think it’s important to get the full picture. Until a monthish ago, I was running this setup. I ran this setup from 3k-7k miles. JB4 Map 6...

  11. DAW FlowMax Turbos - 2 Port and 6 Port - 1 Fast Supra!

    Hey guys. Dropped off my supra this morning to get the 6-port Flow Max and my EOS mani installed. Install today and tuning on thurs by Sameh. did a baseline run on the dyno it's going to get tuned on. This dyno apparently reads low. It's the dyno shop EPC uses, so when they say it runs low...

  12. Euro Performance Center Femto DME Unlock Journey to Finland Live

    11.76 @ 123.15 mph ?, sounds pretty fast to me ?, especially when factoring you only have bolt-ons and the “Excuse Panel” ?

  13. Euro Performance Center Femto DME Unlock Journey to Finland Live

    Some depressing 1/4 times for you guys. Honestly, car behaved great, driver needs major driver mod. :) Only got 2 runs in due to weather. Setup: This is on Stage 2 MultiMap - Map 3 (94 octane), AA DP, NT555R2'S, lowered on Eibach springs. Excuse Panel: tires cold, 2nd gear launch, short...

  14. A first look at the A91 stock calibration.

    Has anyone run a ROM-compare on any MT cars yet? Couple questions - Does an MT car use the same tune as an AT car once unlocked? ie MHD/BM3 OTS Does a 2023 MT car have a different method of load targeting than 2023 AT? I am trying to figure out why JB4 behaves so differently with an MT car...

  15. JB4 logging question: Target boost data unit convention

    Yes, you are on the right track. Since you get consistent throttle cuts around 5k, consider dropping DB down a couple there and 4500 a little as well as you mentioned. You can keep PID at 20 for now. @razorlab , agree timing still needs help. Should start climbing around 4k and peak over 10 deg...

  16. JB4 and Partial unlock questions

    I used custom tuning twice, once for the first set of questions under JB4 heading and that custom tuning refers to JB4 tunes sold by members here. The other is the second set of questions with partial unlock header and refers to bm3 etc…

  17. Collection of JB4 Experiences

    I 100% agree, also I was quoting the flex fuel tune Jesse offers since the bm3 license comes with e30 and e50 maps, so it was the most apples-to-apples comparison. forgot about the app price, yes, sales do exist, but going into that account, I sell Bm3 licenses for a discount as well, so I...

  18. Collection of JB4 Experiences

    So I never said it is cheaper. It is not cheaper, but it is close enough in price where if finances are what is stopping you, it may be close enough apart to warrant taking a look at. In terms of numbers, it goes like this: I will play it with new and used parts. New Jb4- Jb4 w/ BT- $678...

  19. Collection of JB4 Experiences

    Why do people say it's cheaper for a tune and (SORTA) leave out the 1000+ you gotta pay and the risk you gotta take to send it overseas. I get that they don't usually get lost or anything, but still a huge risk JB4 doesn't include. JB4 is one and done if you want, tunes after a new bolt-on...

  20. Help reviewing BM3 OTS map logs

    Before I learned the BM3 logging capabilities, I still had my JB4 in the car. On map 0, so I just used it for logs. On the Stage 2 93 OTS map my timing was hitting 14/15. 9 seems low to me. I can post those logs if anyone wants. To be clear, I was running a BM3 tune but logging with the...
