1M Data Log help please

[JLL111]

Hi guys,

I’m trying to help a mate with his 1M which seems to be having some boost and throttle issues.

The car has the following,

Catless Downpipes
Jb4 and Bluetooth
Chargepipe Plus tial bov
Front mount inter cooler
Catch can

Please find below the data log from a pull today in 3rd with all Nannie controls Off. I can’t understand why when the throttle position is 100% why the throttle is not holding and seems to be all over the shop? Also boost only seems to peak twice and this is running Map 5 Autotuning mode

Thanks in advance 👍

God I hate JB4 logs. Looks like it could be experiencing throttle closures? If you disable the JB4 is everything ok?

Try putting it on datazap.

There are not enough things logged to see what's going on.

Thanks for the reply’s T1M / Brule,

I will see if I can put the rawdata on here.

T1M yes it seems to run fine with JB4 disabled.

Cheers

not enough info

looks like his jb4 is not setup correctly

you need to go through all the dash settings and interface settings and double check
everything

[JB4-335]

Add some more info to the logging list like trims, AFR, ign 1, PWM and IAT

Thanks martymil and JB4-355

Update log added to first post with added info

[martymil]

We need the actual log not a pic

Datazap is not enough either

[JLL111]

Sorry martymil,

I will get it up soon

Definitely get off that ridiculous Map5 autotuning map. And better yet, get a proper flash tune on there, which you can increase the boost safely

Map5 basically increases the boost until the stock ecu detects knock and pulls the timing. It is a very primitive way of tuning and results in very jerky driveability.

Thanks Vincent!

I have advised him to do exactly that.
Hope all is well mate!

Thanks for everyone’s input much appreciated
