Careful because if you say your experience they take it as shit talking

You have a BM3 tune on your F90? Just cat delete and tune to get to low 10s? That is an incredible time

I'm running HCP Custom Tuned outside of Bm3 right now. But my car will be 1 of the Bm3 Dev car
Yes running Full Downpipes (Primary/Secondary) and I think so too, no racegas or max boost like piggybacks are doing to achieve same result.

Best thing about it, is it's been consistent with full interior and full tank of fuel each time I found the opportunity to test at Mexico

Funny I went the other way. Tried RaceChip first but had codes for sensors and the car didn't feel much faster and app showed boost not much higher than factory. Changed to JB4 and zero faults and the car is an animal now. Their app is really second to none too.

After some time my JB4 strangly reads few codes
12AB04 rear o2 sensor disconnected
191C02 tank ventilation system: malfunction
123414 no description
120908 no description
12AC04 no description
120408 reduced power mode

Bare in mind that the app works very well, the car responds excellently and no faults in the car on-board system.

Just wondering what are those in case I need to change the JB4 I have a brand new one sitting idle.


Best regards

Is the car in Diagnostic mode? If not, it won't permit anything to clear the codes—the app tells you this and how to do so.

That said: you'll want to understand why before blindly clearing the codes. Please elaborate on your scenario and history.

Have you verified you're using the latest firmware?

Installed JB4 yesterday, map 1 was a rocket, added proper fuel and went to map 2 and ran 7.08 60-130. While rolling onto throttle in Map 2 I got a CEL, Drivetrain Malfunction. Car is in "reduced power mode" for a Drivetrain Malfunction that I can't clear with the JB4 in diagnostic mode. Code 123408 120408 123426

Three pushes of the start button.
The EWG is so simple to connect not sure where I could have gone wrong, and car ran strong. I will double check my connections in the morning. I sent all info to Terry as well just waiting for a response. Here's a screen shot, it's seems like I clear the code, then I hear a "bing" from the car it's back. Thanks for assisting, I'm new to this platform.[IMG][/IMG]

I ran JB4 for the duration of my F90. Loved it to death. Ran Map1 with 91 and Map6 with race fuel for the drag strip. Deep into the 10.3's with just intake and JB4. If you have troubles email Terry. He answers almost immediately no matter the time.

Sounds like normal JB4 issues. I loved mine for 3 months, then this stuff started happening. Got to the point where every other time I floored it, it would throw a drivetrain malfunction and a ton of codes. Terry had me try going to map 0, still happened. He said it was my car then because map 0 doesn't do anything. Took it off, haven't had an issue since. Just about everyone Ive heard of with a JB4 on this platform has been down the same path. They're garbage.

i thought you were running super fast? What happened? Ugh I'm beyond frustrated. I can deal with something not working, but making me slower is becoming an issue.

He answered me fast, still waiting on some responses but it was late last night. Ran like a monster but now I'm stuck in this limp mode and feel stupid.

You're in the best hands possible if Terry is helping you. Have you tried a firmware upgrade (if one was available relative to current firmware)?

I assume you've tried this: sometimes, clearing isn't enough and the car needs to be driven for a few miles causing the code to clear itself.

I'm on Version 9 with Version 10 Beta and 11 avail. I'm going to take the entire JB4 off, then wait for Terry to get back to me. Yes I've tried driving around after clearing and it still persists. I know you had good success your car is fast.

i thought you were running super fast? What happened? Ugh I'm beyond frustrated. I can deal with something not working, but making me slower is becoming an issue.

He answered me fast, still waiting on some responses but it was late last night. Ran like a monster but now I'm stuck in this limp mode and feel stupid.
You're in the best hands possible if Terry is helping you. Have you tried a firmware upgrade (if one was available relative to current firmware)?

I assume you've tried this: sometimes, clearing isn't enough and the car needs to be driven for a few miles causing the code to clear itself.
I'm on Version 9 with Version 10 Beta and 11 avail. I'm going to take the entire JB4 off, then wait for Terry to get back to me. Yes I've tried driving around after clearing and it still persists. I know you had good success your car is fast.


I had some issues, too, but with incremental updates from Terry, they eventually all went away.

What year is your car?

I only run map 1 (+3 psi over stock) now even using Floridian 93 octane. Map 2 (+4 psi over stock) is too much—in my experience—for regular pump gas. You need higher octane race fuel or snake oil (aka. octane booster).

PS: I enclosed some instructions related to the V9 firmware to ensure you guys are aware and have followed it.
