JB4 Long term users

[Cruce]

Hello all,

I’m looking at getting a JB4 for my Integra (1.5L MT) and I was wondering if anyone has been using one for a while or had used one in the past and how it treated your car. I’ve checked out a Ktuner but I’m not comfortable flashing the ECU.

Thanks in advance!

I've used them on other cars in the past. They work, but are limited. They just work by fudging the metrics around between the ecu and the engine. I haven't known anyone to blow up their engine with it or anything. On my gti I got rid of it after 1 week and went with unitronic for a proper tune. The power delivery was night and day.

Personally, I would much rather flash it because then you're dealing with an ecu that gets legitimate metrics and responds like it's intended to. In either case, taking the car "back to stock" is still identifiable by the dealership as a device or tune previously being present. I don't see what you'd get out of the jb4 that a tune wouldn't give you more of and safer.

Get a Ktuner v1.2 if on a budget. It's sale now at Phearable and Two Step Performance. Not only comes with ktuners base tunes but you'll get their own tune for free by Phearable or TSP.

JB4 tricks the ecu into getting skewed data. JB4 gives some extra HP but limited by the oem max programmed values. A flash tune changes the max programed values so you get even more HP, with similar gas mileage and safer. Both are going to void the warranty so no benefit of one over the other there. JB4 is ok for cars that don't have the option of a flash tuner such as COBB, Ktuner, Hondata, ect, but luckily we do.

Thanks a lot for input, I appreciate it. I might have to reconsider flashing it.

No problem .

Either way, you have plenty of options now. Hondata is pretty popular around here. I've gone down the Cobb route and I've been happy, but Honda community seems aversed to cobb due to issues years ago where they got hit by the epa and had to start making cleaner tunes that didn't impact emissions.

There's also the piggyback options like you mentioned.

There's no true right or wrong, just what aligns with your goals and risk tolerance!

I looked up Cobb but they don’t have anything for the 1.5. I wish they would’ve made with 230 hp. That would’ve kept it far enough from the TLX to sell both.

Yeah, and that would have put it right in gti/gli territory where it should be.

@COBB Tuning, plans for a tune for the 1.5?
