JB4 Issue...Help!

JBird.. · 02-07-2014, 04:00 PM

So I recently purchased a used JB4 Stage 2 and I installed it 2 nights ago. I started in Map 5 and did my three pulls so the JB4 could learn my car. All seemed great until when I was driving to school today I got a SES light while I was just cruising on the highway. I hadn't driven it hard before or anything, it just appeared out of nowhere seemingly. I cleared it and kept driving. I had power and the pedal response was normal. I switched out of Map 5 for my drive home and into Map 1. That seemed to work as no light came on the whole ride home. I then stopped at home and went for a quick drive and once again out of nowhere the SES light came on again. I just read the codes and I have 2, 2775 and 28A0. Are these normal codes or should I get my car looked at? Thanks.

Also I did not have auto clear on. I just took my car for a drive around the block and got on it and its making full power for sure. Should I just leave on auto clear?

Those are probably tuner codes

Ok thanks.

Leave on auto clear, it will only allow important codes to throw the SES.

2775 air mass low, boost leak (tuner code) ... 28A0 Output gas circuit switch (tuner code) keep auto clear on no worries
