BMS JB4 R specific thread

Gonna give some ethanol a try. How much should we add and what FOL for MK7.5?

 

[George Smooth]

On a 7.5 go 3 gal to the tank and FOL remains 45.

Thanks! I shot you an email also so no need to respond. Hopefully some E will get rid of my timing corrections!

Few logs of maps 0, 2, 3, & 4 on my 7.5 DSG. Even on Map 0 it isn't always hitting target, and never really hits it on the additive maps.
Should I be investigating a boost leak or is it common for R's to hit this low below target? 100% stock hardware so maybe I'm just being unrealistic.

Map 0
Map 2
Map 3
Map 4
Map 4 again

Make that 0

Not sure why that is 1. Make it 0.

Is there another station of 93 available nearby? Lotta knock for even map2.

 

[Brian_]

Thanks, will make those changes and try some different 93 on map 1.

Doubt I’ll want to go higher than map 1 anyway with stock IC and summer around the corner.

I did a few logs running Map 3 yesterday (typically run Map 6). One second/third gear pull and a third gear pull. Primary modifications are catted downpipe, intake, catback exhaust, and turbo intake.

Any thoughts on Map 3 logs?

Lotta corrections. Is this 93 gas?

Yes, 93 Octane from BP.

Try map1

 

[GolfARGH]

Try map1

Will do, also plan on swapping the NGK plugs with RS7s.

Also started throwing a 539B code per the JB4. Any idea what that is? Couldn't find anything via search....

 

[Diggs24]

Put a real code reader on it.

Just installed my JB4 that was on my Mk7 GTI and not really happy with this log. Seems to be lean, also not quiet sure what that hiccup was at 3200rpm. Running map 1, 3rd gear, shell 91 octane and fol 45 https://datazap.me/u/dthissen/mk75-golf-r-jb4?log=0&data=1-4
