Default 1.6t with flash tune map 6 help - 01-03-2021, 12:32 PM

Hello again, I know I've been posting a lot but I'm trying to enjoy the jb4. I'm not familiar with reading logs so I need help setting up map 6.

I have a stage 1 flash tune and I am running the jb4 over that. I'm also running 93 octane and I'm full Bolton minus wmi. I saw a spike on my log to 28psi which is pretty high from what I'm told and that's on map 1 with bit0 on and bit6 on. I'll attach the log. Anyways, I'm thinking about dropping the boost in map 6 I just need help to do it properly and make sure everything is running right.

Do some longer full throttle runs on map0. Also set FUA = 2 to see if that gets timing 2-4 logging.

Here is the log. Tried a 2nd and 3rd gear pull. Was wheel spinning too much. Then did just a 3rd gear pull.

OK good. Let's set 1st gear to 4psi to see if we can get wheel spin under control.

Then on map6 set all values to 1.5psi, and grab a log on map6.

Thanks again for the help. Ok, just making sure I'm understanding you correctly. You want me to go to settings and on MAX BOOST 1ST put 4psi? Is that adding 4 psi to first gear through the jb4 or is that limiting me to 4 psi in first? And I'll drop the values to 1.5 on map 6 then send you the log this evening.

Here is the map 6 log. 1st gear boost is 4psi,1.5psi across the board on map 6.

I did notice that on my last pull the jb4 reverted to map 0. I left it in map 0 the rest of my drive. Not running any maps until I hear from you. Car still runs great. No codes. But I heard it will do that to protect the motor if it detects abnormalities.

Last safety 1 means you exceeded your predefined boost limit. Maybe raise that up to 27psi. But log looks generally OK, you can change those 1.5 values to 2psi.

Good afternoon Terry. I received my fuel wire adapter this week and I just installed it. I took 2 logs, one on black wire #2 and one with red wire. Could you tell me which one the fuel wire is working with if at all? I'm trying to run e30 with map 6.Thanks.

We would need longer runs with each to evaluate. Like 40-100 or something, on a safe private track of course. It has to be under boost enough that fuel enrichment in the log goes up.

Hey Terry I just noticed on all my logs fuel enrichment has no activity but I did notice on the black wire log there is activity on my last pull. Does that man the jb4 is picking up the signal from the fuel wire? ��

Fuel enrichment is the request out and that is based on the ECU's AFR target. Fuel enrichment is dynamic so only kicks on when it needs to lean out the factory AFR. With your flash the mapping is going to be a lot different than a factory vehicle. But if you want me to evaluate it I'll longer sustained full throttle runs. Ideally something like a 1/4 mile pull on each for example.

For your model appears to be the red wire, but the base algorithm seems off causing us to enrich the AFR rather than lean it out. Leave it on the red wire, change FUA back to 0, and relog.

I'll need to add an additional FUA option likely for your model. Also let me know if the in dash map switching works on FUA = 0 or FUA = 2.

I'll get to work on an FUA = 4 option to get what we need here once I confirm the above.
