Question about JB+ 100% long term - BMW 1 Series Coupe Forum / 1 Series Convertible Forum (1M / tii / 135i / 128i / Coupe / Cabrio / Hatchback) (BMW E82 E88 128i 130i 135i)

I just got the JB+ last week and recently installed the BMS DCI on the car and I love it. Its currently set on 50% with 93 octane and i'm really contemplating on turning it up to either 75% or 100%.

Any of you guys who have been running JB+ long term at a higher setting than 50% had any problems? By long term i'm saying around a year?

I already bought a BT scanner, its on its way to me so I will be able to clear codes if necessary. However I don't really want to do the solenoid bypass since its just one more thing I need to revert if I go back to the dealer.

Thanks in advance.

JB+ hasn't been out that long. Came out earlier this year, so I don't think you're going to get the answer you're looking for.

However, I've been running mine at 75% w/the bypass since it came out and no codes. Bypass takes less time to revert back than taking your JB+ out, if you ever have to go to the dealer, so no reason not to do it, IMO.

Xin1120,

Been running SSTT (similar to JB+ @ 75-80%) for 18,000 miles on UK 98 octane (~US 93) with absolutely no problems or codes (got BT).

Mad.

hmmm i'm just concerned about the long term effect on our turbos. I love the power but do I love it enough to blow my turbos...

Even at 100% you're running a lot less boost than the JB3 guys. These compressors have a long record of reliable performance provided you tune it right and taper the top end boost. I wouldn't worry about the JB+ @ 100% at all. The bypass is worth the effort as well at 100%.
