map tweek
 

Hi all i now have a 3" nur spec r system on the rb, i take it the map is goin to need tweeking any ideas on the cost of this?? cheers!

Who mapped it before?

Jgm

Wouldnt mind getting it on the rollers after xmas to see what its pushing, just fitted a new boost gauge and showing 1 - 1.1 bar of boost, would like to get it tweaked to raise the torque to the 400 mark if possible too!

Simon won't charge too much I'm sure e mail him

Cheers mate yeah il get on it! ;)

What exhaust did you have before with original map?

Must have been the h&s which was a 2.5" system now running 3" i have noticed a few fuel cuts on boost without "engine check" almost headbutting the steering wheel and with a backfire, also if driving normal but changing gears just as turbo kicks in at 3000rpm its abit jolty/hesitent and was fine before hand after ajusting the joiner from ic to tb,dont think its boost spike? as it gets to 1 bar and holds without dropping, my last classic running the z4 used to do the same sort of thing but it boost to just under a bar then boost to 1.5bar almost putting my head thru the screen, best to lay off boost till i get the map set with new exhaust??

Will most likely be running lean, If you went from 2.5" to 3" di exhaust..I wouldn't have driven mine on boost without a map check with that kind of system change.

Cheers for the heads up!! il be layin off the boost then thats for sure!! Looks like 2 months without boost!:(

I agree with Ginola, get it back running on vpower like we were talking about and then get a map sorted :) Sounds really good now though!!

Haha it sounds like an animal all the neighbours love me especially at 630am while i let it warm up!!:) spoke to simon today and hes goin to get it all sorted for me so that should be an interesting day!! Be good to see what shes pushing on paper goin to get boost raised to 1.3 or higher if safe to do so!

Would potentially cause boost spiking and may change the engine loading and therefore the position on the map, causing different fuel/timing to be run for the same rpm.
