KJT E30 ECU + BMS TCU BEF is fire!!!

Going from JB4 only to these 2 BEF tunes is a really day and night difference. Initially all I wanted to do was the TCU tune but learning about KJT's ECU tune really made me more curious with all the benefits it comes with. This combo is exactly what I was looking for. Burbles, better e85 adaption, better overboost management, more power, more torque, no more jerky downshifts from 3 to 2 that I always noticed. Much smoother shifts in comfort. Also very quick and crisp upshifts and downshifts in sport/custom mode. Here are 2 quick initial impression videos I made today. The burbles are the perfect amount, not too much not too little. The BOV are also much louder, power comes on much smoother and boost builds up FAR faster. No more of that dead throttle feel as well. The exhaust also sounds different, slightly louder and deeper but more refined! You can hear the turbo whistle way more than ever! It sounds so much nicer now even with the stock primaries.

I will say the EK1 device was being an absolute PAIN in the ass. It kept giving issues with the files not being read from the sd card. We ended up having to format the sd card and recreate the folders using initial capitalized letters. Then once we ejected the sd card and turned on the EK1 we saw the files FINALLY. The ek1 was already upgraded and registered online as well. Totally made my day going for a first drive but I was already so tired I will likely capture some more videos at another time. If anyone is on the fence on this ABSOLUTELY GO FOR IT! Hats off to the folks at BMS and KJT. They are a dream team.

My mods besides the BEF: K&N intakes, GFB 9012 BOV, Ark Secondaries, Mbrp Pro Active catback with akrapovic cf tips, eibach springs and sway bars, bms FMIC, bms chargepipes, moshimotto catch can, moshimotto rear camber arms, fuel it ethanol analyzer (so handy if you run e85).

Yes, sounds great… how is the drone at highway speeds?

Surprisingly the drone in the 2-3k rpm even with valves fully open is less. Im comfort mode just regular freeway speeds is also less than before. I heard that KJT was claiming on a livestream that his tune helps with drone. Well, I can definitely say he wasn't kidding. I do have to connect my APR wireless valve controller this weekend to manually control the valves since his tune does not seem to work with the oem valves. Not an issue anyway as I prefer to fully open the valves which also will help with less wear on the valves/actuators.

Here is a video I took today just some driving with manual shifting:
