Can you post your MSQ as well? It would be useful to see what your settings are currently at.

 

Why did you upload that using that **** service? Just attach it to the post... took me 2 minutes to even start the download, and even then I was worried I'd click some bs advertisement.

 

Ok from the mess of a log- Your fuel is a complete mess. Where did you get your map?

At around 47kpa and 3000 rpm you have just about zero fuel. This will cause the "splutters and splatters and judders around".

Are you using the AFR Target table? If so, it's telling the car to go lean. The target table is a mess. Disable it until you've worked out your fuel. There are other issues though. Just upload your MSQ file.

 

thanks buddy,

i realy appreciate it,

where do i find my msq file?

 

Hoy **** Dave, what've you done to your map?!?

the .msq is the tune, file>save tune as.

 

tell me about it,

it was running perfectly i have no idea what iv done.

heres the msq

 

by the sounds of it youd be best to read up and do it yourself and deal with the learning curve rather than ask here and do a few things because your told to and get a car that runs not great and still dont know how to fix that.

True story. The little important info you pick up here and now might help but you will have no idea why it helped. Do some reading. The MS manual is great!

 

i respecxt that reading and learning would be ideal, but this is my daily runner, hence why im posted for help quickly.

if you wouldnt mind spending some time and telling me what to do i would appreciate it.

 

Put the stock computer back in, wire wastegate open, dont boost, lrn2mgasqt?

Your VE and spark tables need to be completely redone. I'd recommend taking it to a shop with a chassis dyno (rolling road), preferably a steady state version, and have them dial in those tables. Sure, it is a bit price, but four hours of dyno time can save you four months of frustration.
