SUPRA ULTIMATE JB4 GUIDE AND LOG REVIEW (V1)

[ColonelAdama]

Could someone take a Quick Look at this log? Seems to be dying off top-end.

This is Map 1, 91 octane on my 2020 supra. This log does start in 2nd gear and goes to third.

I think my problem is the lack of good fuel where I live. Might try to mix a couple gallons of e50 from a flex fuel pump by me.

Yeah sorry man, just an octane issue. Adding 2-3 gal of E would change everything

Hi guys, this is a very helpful thread. I just made the switch from JB+ to JB4.

Which map do y'all recommend for 450whp with no E blend, just 93?

Thanks for the input. I figured it’s because of fuel. When you say to add 2-3 gallons of E, do you mean 2-3 gallons of E50 like I had mentioned, or 2-3 gallons of e85?

23 MT 3.0. Here is what I logged today guys. Thanks to anyone who would like to advise. Still figuring out logging and data zap. I have it on group logging. Don’t know if that’s good or bad. I did a map 1, accidentally must have hit map 7, and followed up with a map2. 93 octane ****** dp, intake, and charge pipe

Map2 ran crappy as I expected it would due to the dp.
Not sure if this is how to share my logs but hopefully this works.
@ColonelAdama I’m not great at computer stuff lol. Thanks in advance

Closest bet to 450 is Map 4 probably, if your timing holds up. not very likely on just 93

2-3 gallons of e85

PM me your email and I'll send you the MT JB4 firmware and a map that should work decently

Ok so I’ve added 2 gallons of E and the car already feels significantly better on Map 1. If you could take a Quick Look at this log that’d be greatly appreciated.

Timing is like non-existent unfortunately. Can you send a log on map 4 next? It should actually drop the boost compared to map 1. Enable bit 3 too

looks good!

Should I add a couple more gallons of E then? I’ll have to in order to run map 4 anyways so that I’m at E30. And what is bit 3? Thanks

Just looked it up…IAT/Timing spoofing. My IAT is pretty high so maybe it’s causing it to pull timing?

I wouldn't use more than 3 gallons E85 total to do a first Map 4 log. Bit 3 makes it so the JB4 can target boost levels under stock if it needs to.

Just got my jb4 last night and I did map 2 group log with cruising and a couple of pulls, I know it’s not a wot 3rd gear but I was hoping you can check if everything looks good.

Mods
cts catless downpipe
cts intake
exhaust

These are the settings I typically recommend for catless cars nowadays:

FF = 25

duty_15	duty_20	duty_25	duty_30	duty_35	duty_40	duty_45	duty_50	duty_55	duty_60	duty_65	duty_70
50​	50​	50​	50​	50​	50​	55​	60​	65​	65​	65​	65​

Ok will change the duty cycles, I’m I good to go on map 4 and run e30 ?
