SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[ColonelAdama]

Inching closer to 8s 60-130

Stock rubber not hooking up. Highest trap speed in the 1/4.

Was able to into the 11s in 1/4 but still not a good launch

Here below I was practicing my launch. Wonder what the 1/4 would’ve been had I stayed in it.

Thanks everyone. Your tips and suggestions are working.

Was this map 6? log?

Map 2. I didn’t log it today. I was looking at dragy numbers

should be easy to get into 8s with the map 6. its around 20-25whp more than map 2

Ok until you give me the ok I’m not switching from Map 2. ?

I logged a 2nd gear pull today if you’re interested in seeing.

eh 3rd gear or 4th gear is best for evaluation. Can see how map 2 looks and maybe move to map 6. may need a little more E

good to hear. I actually googled JB4 vs MHD and there’s not a lot of hard evidence separating the two other than those who have gone from JB4 to full unlock say it’s a big difference. However there’s not many or I haven’t seen many dyno or draggy comparisons other than the dyno short burger did on their E30 tune vs a MHD E40 tune.

I don’t have any “goals” for the car. Just a fun street car.

Will report back when i know about all of this from my own cars experience . DME is on its way to femto right now and I have done a best of 8.4 60-130 on a full weight e37 mix 6mt jb4. Will get lots of testing next month once its unlocked and then time to do the good ole BEF

stock/high flow cats are running high 7s on MHD E40

catless custom tune MHD E50 can run 7.3s

for added context, OTS MHD E40 and OTS BM3 E50 are pretty much bumper to bumper
(AT)(AT)(AT) idk about MT numbers down here

whats weird about that 7.3 that was just run by the Botti tuned car is that he recently ran another car and he posted his video and his 60-130 using the timestamps on his video and his gps mph on the app it was like a 9 second pass which confused me

I will get a 3rd gear pull.
Thanks

Launch in 2nd and put a tire on. 3.5 or lower all day 0-60

Hey ordered the fuel pressure upgrade kit. Once I get it on, will get more logs. Until then still running on map 2.

Correct me if I’m wrong with the fuel pressure upgrade kit I can run E30+?

Thanks

Yep E35 would be a good start

I have the JB4 fuel pressure sensor installed. Haven’t started the car. Will fire it up tomorrow.

Now seems like I will need the fuel it flex fuel kit next.

Anyone running the fuel pressure sensor seeing good results? How much E?

Running the jb4 with fuel sensor set at 70 and fuel-it (this is only for showing e content in jb4) but I also am running water/meth injection and did the DAW hypercore upgrade, AA dp. Running around e30-35 w/91 oct and hitting 27psi and still under 45 trims worst case. Feels really good.

Hey I’m down to 1 bar of fuel. 9 gallons of 93 and 4 gallons of E85?

9.5 gallons of 93
3.8 gallons of E85

Map 2. 3rd gear pull. Car feels slower. Fuel pressure sensor installed. Changed FOL to 70. No other changes. Running latest firmware @ColonelAdama advised me to run.
