Looks good, thx

Here's a 2nd and 3rd gear pull from a veloster N base (non-performance pack) running 93 octane and map6 on v13

I will need to record some logs for you. Was running my usual e85 5gallons rest 91 and ran into the stutter as before. This time check engine light came on and the car was hesitating. I tried to pull the code but nothing came up. I turned the car off and back on and went away. Running map 2 now to be safe. Did notice a small hesitation on a highway pull but nowhere as bad as it was on stage 3.

I drive a base 2019 Veloster N and I'm using map 6 to offset the tune difference the performance pack has.

No need for photos like that, just CSV files

Looks OK but really short runs, grab some longer runs!

[CiHKAL]

I hope this provides more helpful info about how FW 13 beta is doing.

I did a couple pulls this morning trying to grab longer runs where I can, apologize if it's a little short still.

From my layman's POV I'm really happy with the JB4. I have experience with Hondata and APR with other fun cars I have, or have access to. This device though, is really awesome!

If you want specific data I'm happy to provide it if it helps with evaluating the firmware, thanks!

Awesome, glad to hear the system and car are running well!

[stargtsi]

please review logs. I had break up under full throttle multiple times
little over 5gal e85 with rest 91 running map 2 even worse with map 3

[sym]

I just got a CEL for P0174 (Bank 1 too lean) which I can't delete. The only change I've made recently is updating to V13. So I've been fine for the past 10,000 or so miles on the current plugs.

Any ideas? I went heavier on the E85 last fill (6 gallons E85 to 8 gallons 93, which was about 200 miles ago), but the only E85 code I've ever gotten was a MAP sensor issue when I accidentally filled the whole tank with E85 (someone started talking to me when I was filling my car).

[Terry @ BMS]

Normal fault from running a heavier E85 mix. Delete faults with ignition on, engine off. It will come back eventually until you lighten the E85 mix.

Keep it on map2 then, and lets see a longer run for comparison.

Wow - how did you solve the 100% E85 problem? Were you able to drive it on map0 or whatever to burn off a few gallons?

Did two full send Runs Map 5 V13 firmware. 2 Gal of Sunoco 260 GT

DA was 6500 + today so not my best 1/4 mile runs but these were 12.6's 1/4's via draggy it felt strong.

Messed up and didnt save the log for the last run today. Even on Map 2 sputtered hard check engine light and car sputtered until I turned the car off and restarted. No code pulled when I tried to check again. It now defaulted to Map 0 and leaving it for now. Did pulls on map 0 and seems fine. The major stutter happened in between 3k and 4500k

A high DA like that is always going to be hard but logs look clean to me!

If you got a CEL make sure you don't delete codes, need to read that CEL so you know what cylinder is acting up. It should still be there maybe try reading with a generic OBDII reader just to rule out any sort of JB4 reading bug?

Filled up with 93 at about 1/3 of a tank left. Cleared the CEL and about 100 miles later it looks like we're good. Thank you.

The 100% E85 was surprisingly smooth. It broke up at high (90%+) throttle due to what I suspect to be the fuel pressure issue. I had a 300 mile drive shortly after so I suppressed my desire to go WOT and filled up with 93 once I hit 1/3 of a tank.

I was able to pull the codes with a reader.
P0302 and P0306 cylinder 2 and 6 missfire.
No issues when running map 0. This is odd as I had no troubles for last 8 months running map 3 til now. Debating on changing plugs to the 2 step colder densos

[Terry @ BMS]

New plugs are a good start at least in those cylinders, gap down to 0.020" since you're having issues.

Im ordering full 6 set since doing 2 steps colder this time. Still recommend gapping at .20 or .22 since will be running map 3 max.

For the 2step we suggest 0.020, a little tighter than the usual DENSO plugs.

[Terry @ BMS]

Got some EWG connector samples in. Sent one set out already, could use a couple more cars who need them. The first most obvious application seems to be cars with modified exhaust systems, stock flash or aftermarket flash, that are over-boosting. If you think you'd make a good test candidate email me.

Installation isn't too bad. 4 wires plug in to existing JB4 harness positions. If you already have the IAT wire installed, that has to be relocated (cut/spliced unless you have a DSUB removal tool). The EWG on the passenger side requires airbox bottom to come up to reach it while I was able to get the driver side without removing anything, although the connector is a bit finicky/tight.

Can't wait to see the results!
