JB4 winter map?

I have JB4 from juiced up and hoping it lands tomorrow.

I have no other mods at the moment so i guess map 1 is the only option.. how ever some people run map 2 with just DCI so i was wondering how safe it would be to run that with no bolt ons when the outside temps are so low??

I wouldn't bother, what are the chances of getting traction in this weather anyway? Whilst your timing will be fine with good petrol and low intake temps, your EGTs will probably be high due to the cats still being present in the downpipes.

Yeah fair point just curious as don't know an awful lot about the jb4 read a number of threads on here which have been posted in last 6 months.

Noticed you are pretty much fully modified with bolt ons. Epic!.

So map 1 it is then.

Or map 5? Or will that not make a difference on a stock cat

I ran map 5 on a standard car for a while. Should be fine.

Map 5 is your best bet.

Be careful on Icey Roads though!

Be careful with the upper and lower filter housing at the base of the windscreen - they break easily!
