SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[deadhead]

Okay, will do. Literally just put it on before taking it out for a quick drive.

DP is being installed tomorrow and then I'll post better map 2 logs.

use the recommended downpipe duty bias settings in the first post at FF 35 (catless) or FF 40 (catted)

looks good, just little duty adjustments at this point

duty_15	duty_20	duty_25	duty_30	duty_35	duty_40	duty_45	duty_50	duty_55	duty_60	duty_65	duty_70
35​	35​	35​	35​	40​	38​	40​	45​	52​	52​	59​	59​

Sorry for the delay! Revisions completed! Had a bit extra on the front end my bad had someone helping me log it!

Looks good to go!

How do you check if timing is healthy and there is no timing corrections

There is a helpful image in the first post for it

Awesome! Thank you for all your help! Appreciate all that you do for us!

As a final note, I know there are always people questioning whether or not the JB4 is worth it / worth it for MTs due to the past issues and I can say from my experience with it and having Colonel Adamas assistance that I have had absolutely no issues so far and have 0 regrets going down this route for what I was looking for in my Supra. The pulls are smooth, you can feel the power, and she stays 10 toes down every single time. I have already shown off the tune to 2 separate V8 Camaros who were less than thrilled with the results. ?

I would love to send my ECU out to Femto for a full unlock but given the hassle it would be for me specifically (as this is my daily driver) and the huge increase in price it would be it was not worth it for what I want to do with my Supra. I would say if you wanted more power out of your Supra and are not ready to commit to a full unlock then the JB4 and some potential adjustments will not let you down if you're looking for a good bump in power. I plan on putting her on a dyno hopefully soon and once I do I will for sure post my results!

Map 1 will be good for a decent dyno result, if you want to consider a custom map 6 you can let me know. I did @RyanA90 's car on E35 and it was 450whp+, probably a good 30-40whp over map 1

You would need the FP connection upgrade though

Definitely some convincing gains. I will for sure consider it. My only concern is that this is my daily and I know as the E content goes up the MPG goes down ? but that is why I call them Smiles Per Gallon.

Its not as bad as you would think + the e85 is cheaper

 

[ColonelAdama]

I do e25 mix on custom map 6. Still get advertised MPG. I do get 34+MPG with 91ACN pump on the freeway if I drive 65. My car is an AT.

Yea I'm not a good example for mpg. Not a daily so it gets beaten on E40 exclusively. 15 mpg ?

 

[ColonelAdama]

"Adjust duty bias as needed so that ecu_psi is roughly 1 psi below dme_bt to achieve max power without throttle closures." I am running custom map6. Car runs fine no issue. No throttle closure. My ecu_psi is almost always 2-3psi below dme_Bt. Is this normal ?

You can post a log. Usually not an issue if underboosting a little

As the E content goes up the price per gallon goes down as well

Welcome back forum. Here's a cool one I've been working on this week.
https://datazap.me/u/coloneladama/log-1753761986?log=0&data=1-3-4-11

Ultraflow X + BMS PI CANFUEL + BEF on E65 at 29+ psi. Should be over 600whp easily. Still working out some throttle closures in the BEF.

@mustafazumit pushing the JB4/BEF platform!

Evening, and I finally made it back. Been unfortunately quite busy and away, unable to play.
Here is my initial log. 2024 MT with catted AA downpipe and MST intake. This was done on map 1 with 93 octane. (Is it possible to verify if the octane sucks or not?)
