Supra 2.0: R R8TED Build - E30 Protune (DaBears and JB4)

[R_R8TED]

For anyone who has a locked ECU, be sure and speak with Jesse Dabears ( @mkv_zupr4 or @DaBears ). He did such a phenomenal job on a custom 93 tune via the JB4, that I went ahead and ordered the Fuel-it Ethanol Kit and got started immediately on a E30 Map. The timing is perfect and the powerband is so smooth and strong now.

It's a conservative tune but to no surprise, is night and day difference from OEM...especially on the E30 blend! I'm a couple tenths from hitting upper 3s for 0-60 (logged with Dragy) and that's with lots of room left for improvement from the launch on my side. Jesse worked with me for weeks getting everything dialed in perfectly. Lots of data logging, dozens of pulls (never one issue or CEL, minus the Wastegate adaption process which is totally normal on this platform and the JB4 explained this in the code retrieval) and I was able to learn a ton from him on the JB4 piggyback system. I used this on my Type-R and Golf R as well with zero issues.

The B48 is very responsive and in the right hands is a fantastic powerplant for those wanting the significantly lighter model with an fairly big edge through the twisties. We are looking at around 320whp and 350wtq on the E30 map, so this is a very nice bump in power and speed for those wanting performance close to the stock 3.0 numbers. The power to weight ratio is quite healthy now ;b

Looking to do exhaust next, so if anyone has recommendations please let me know!

What's your max psi on e30?

What's your max psi on e30?

I'm guessing 18-19 without meth on E30, possibly 20, but that seems like pushing it pretty hard.

It peaks around 21.5-22 and then tapers off.

You were close! ?

Spun first and 2nd using launch control, but I was able to get a 12.7 for the 1/4 mile. With cooler temps and a better start, I expect mid to low 12s ?

Anyone have tips for getting off the line faster?

Yes.

0. Sport Mode
1. Tap Traction Control - (turn off traction)
2. Hold Traction Control - (turn off VSC)
3. Switch to manual mode
4. Burnout in First gear in water box
5. Approach staging lights
6. Shift to 2nd
7. Attempt to push the brake pedal through the floor with your LEFT foot
8. While holding the brake pedal down, bring RPWs up to ~2k RPMs quickly (you'll feel the car "squat"), this is the torque converter loading. Boost will climb.
9. On Green - Mash gas & release brake
10. Shift when you see the indicator reach 55-5600 RPMs
10a. Don't shift out of 5th, ride it through.

Thanks for the info! I'll give this a try ?

i ran 11.9 completely stock doing exactly what @zrk said except i launched from first. breaking into 11s should be no problem with the jb4

It'll be a bit slower with the 4 banger, but it should still get close.

Next up for the build.

Hey man, am I reading this correctly that your only mod is the JB4 and the E30 tune and you're running 12s? No catless DP yet? That's pretty freaking good for a lil four-banger.

This should be possible. Yeah. Crank of the boost and go.
