I may have to pull plugs and recheck them but I’m sure I gapped them correctly.

Just saw a TSB for this code and it’s for message service engine soon, which I think I may have also seen in the dash. The fix is a reprogram of brake system control module with latest software. I may have to take jb4 off and bring to dealer, or wait and see if it happens again.

Thanks man. I would love to tune the car but not ready to void my warranty. I’m new to jb4 but wondering how much a tuner like Scott can do with it. I would like someone to look at logs and see if they can smooth it out. Seems like the power cuts out like it reached its target. I’m thinking that...

P25A2 looks like brake system control module. What makes you think it could be from the plugs? The plugs were not gapped correctly out of the box like they claim. I gapped them down to .26 It was first plugs I have gapped but almost certain I did it correctly. Havent had any drivability...

Thanks for reply. I was in full traction control and figured with some wheel spin it messed with computer. I need to play with the settings and setup my mode and Vmode. I don’t really care for the suspension in anything but tour, I’m old lol. To be honest it’s kind of confusing. My hellcat was...

My traction/stability light was on as well then cleared itself along with cel. Must be something with eDiff and computer or something. Anyone else have this happen? Will take to dealer if it happens again.

Challenger Scat pack manual or charger if auto is ok. Actually just noticed your budget would allow for slightly used hellcats either challenger m6 or charger.

Anyone get this message after launching car? Have had this happen now twice. A10 2023 4BW with only 6,000 miles. Also get a flashing cel that goes out by itself. Only thing I have seen is something about a wiring harness tsb that came out while back. Car is exactly a year old and haven’t had...

Anyone use Map3 ethanol blend? If so how much E to 93 did you use? I know tapout never validated map3 and I’m a little hesitant to try it myself. Also what about Boostane? Will it help with any of the maps? I have 93 in Texas but wondering if putting some in will increase power with Map2?

I got it used so never set up account. With the sharing of info with insurance companies I really don’t want to give them info. In that case guess I have to deal with it 🤷🏻‍♂️

Anyone know how to get rid of annoying message that says OnStar is not activated and to contact OnStar. I have to hit OK to make the message go away everytime I start car. It may say something about Sirius XM as well. I just want it to stop lol. Guessing you can’t get rid of it unless you renew...

lol I actually forgot that damn thing twice. I had trouble getting it to clear with hp tuners and think it finally cleared on its own. Hopefully the battery will do the trick.

Did you check the electrical connections as well. I left the one on drivers side off twice actually lol.

Have also heard removing negative battery cable for like 5-10mins maybe

You can go to autozone or similar place and have them clear it for you. Not sure if it will clear by itself. May want to try and few ignition cycles maybe.

Well dyno session didn’t go all that great. They had a stored car in front of rollers so couldn’t use any fans. Should have walked but figured was only doing two pulls and car was already strapped down when I got to the back. Should have done map2 first but did map0 (stock). The fuel bias was...

I will update with the results

Will the dyno shop need to plug into obd port? I have my jb4 plugged in. Not doing any tunning obviously just want to see stock vs jb4 power gains.
