Ah, of course. Well none of the baseline tunes I've made would help you, but I do think that APR left a little on the table with their IS20 tunes, which is rare for them. Of course you will only start seeing significant gains with stacking once you add some ethanol or if you get meth injection.

Has anyone had issues with the JB4 mobile app? It was working for me at some point in the past (when I initially installed the JB4 and set to map 2), but I tried connecting recently without success. The settings appear different in the new version of the app, but I can't manage to connect. Using OTG and USB connection.

Don't have a great log so I won't post it but...

Switched to map 1 and then 2 as soon as I threw it in. AFRs even on map 4 at WOT are in the 14.8-15.0 range. Isn't that lean as shit?

For the record using twin dads setups and with a catless DP.

Car is hauling ass. I haven't logged it but its pretty fun!

Good to hear. I was just recommending some settings for someone on Facebook. Have you tried it with e30 yet and more boost?

Did a more conservative map 6 on my Alltrack to fit my daily driving style, targeting 16 psi max. Car is running really smooth and I got a bit better mpg on my short commute than running map 2 using 93 octane, not sure why...

3rd gear log:
https://datazap.me/u/ch1turbo/62?log=0&data=1-3-4-11-14-18&solo=14&zoom=182-301

0-60 according to the timestamp (with launch control):
https://datazap.me/u/ch1turbo/62?log=0&data=0-1-36&solo=4-14-36&zoom=578-643&mark=588-633

Here're my settings:
15 2.5
20 4.0
25 4.0
30 4.0
35 4.0
40 4.8
45 4.8
50 4.8
55 5.0 (4.5 in the log)
60 4.3
65 3.5
70 3.5

Comments and suggestions welcome. Car is otherwise all stock. :)

Here's what I have for map 6 so far. I tried to go a little conservative. Log is not nearly as smooth as I think it should be but I have no idea where to even start.

Car is stock running 93.

Does AFR Bias = Fuel Bias? The reason I ask is because all my fuel bias values are 0, and in the first post George mentions that AFR Bias should be 100. I don't have anything that says AFR Bias...

All fuel bias is 0. Should this be 100?

I was on the way home today on the highway and spotted an SRT8 Charger coming up quick. I waited and then egged him on. We had pretty wide open highway and did a few runs. It was door to door each time until the speed limiter hit. The e30 really makes a difference

Fuel biases should all be 100 and duty bias 0

For the past two weeks I had what I thought was a transmission problem - usually, but not always, when accelerating power would cut out for a fraction of a second and then continue causing a stuttering sensation. Switching to map 0 didn't fix it.


Today I removed the JB4 and it seems to have fixed the problem. I was curious if others had experienced this and worked through to a solution.

FWIW - I'm running the latest firmware.

Hi,
this is exactly what I felt. But not for long now. It started now in the mornings since it is getting cold again. And the other thing is it started now with the new firmware update. It has never done it before with the previous versions.
It feels like massive misfires or so. Like the fuel support stops for a sec. I don't know.
I think I go back to the pre pre version and try again.
In my opinion the version 5 was the most stabile one. Since version 6 I get hundreds of codes every day. It didn't do that before.

Chers

Were his AFRs in the 14s at full boost because of the fuel bias being zero? I assume so.

Amazing how the motor didn't explode. The IATs were relatively high at 91 degree too! Looks like the ecu was still working to advance timing also? I'm a little amazed how well these ECUs adapt.

Makes me wonder how a ECU tune that wasn't completely crazy could blow a motor.

I ordered a JB4, so hoping to join the fun soon. I'll be running the JB4 stacked on top of my Stage 1 APR tune. IS20 is also on the way but may take some time to get to know the JB4 before I put the IS20 in.
