SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[ColonelAdama]

How do you route the cable for the OBD2 port with a manual? There's a hose for the clutch slave where you would normally run it through.

I just did it behind the door lol. There's enough room not to pinch

I did this too. I know you can wiggle your way through the firewall with the line there but I realized if I wanted to remove it would be a pain too.

So I reached to Burger Motorsports and Terry recommended the door route as well. He sent me some pics. I personally don't like the looks of it but I guess that's the simplest option.

Yep, unless it really bothers you. It is the best way on MTs.

Could you please send me those pics or post them here? I've got a jb4 waiting to be installed

Hey! Have a question for anyone here or @ColonelAdama - Car has been hesitating under throttle if I get in the gas quickly almost like Traction Control is cutting power? If I roll into the throttle, car feels amazing and pulls hard. Not sure what may be happening. I have tried with VSC on and off and it’s the same; if I stab the pedal quickly in 3rd the car really bogs and hesitates.

Attached is a log from today, I think the JB4 combines maps now?? I had three runs. A quick 3rd - 4th gear run (without issues) a 2nd-3rd gear run (without issues) and then another log of flooring the car quickly in 3rd gear where it bogs. I appreciate any help! Going to flash back to map1 tomorrow and give it a drive. See if it gets any better.

Just ran the car in Map1 for a bunch of pulls. Doesn’t pull as hard as Map6, but zero issues with losing power and hesitating. Darn

Throttle closed to 24. DME ain't happy.

Update to V24 firmware and drop FF to 48, see if it helps at all.

Should I have Bit 6 selected? I don’t think I ever had it selected

All it does is turn map1-3 into absolute mode, not sure it does anything otherwise
