terribleturner Posted January 28, 2006 Share Posted January 28, 2006 What difference would it make if i stick with my Nur Spec, get the car mapped and then a few months down the line get the BL System?? Will i need to get the car mapped again?? Quote Link to comment Share on other sites More sharing options...
BURT Posted January 28, 2006 Share Posted January 28, 2006 yes matey you will, the fuelling is different. Quote Link to comment Share on other sites More sharing options...

Matt Harwood Posted January 28, 2006 Share Posted January 28, 2006 To be Honest, I doubt it would make much difference. They're both going to be free flow exhausts. OK so you may be able to squeeze another 2hp if you did get it re-mapped, but I can't see it could make any critical difference. Obviously if you have the choice of getting it mapped after the exhaust is changed, that would be prefereble, but don't lose any sleep over it.

LeeT Posted January 28, 2006 Share Posted January 28, 2006 yes matey you will, the fuelling is different. how did you work that one out? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 28, 2006 Share Posted January 28, 2006 If your changing from one type of free flow exhaust to another with no change in pipe size or removing a cat, it won't make enough difference to warrant a remap. Quote Link to comment Share on other sites More sharing options...
b_have Posted January 28, 2006 Share Posted January 28, 2006 If you ever get a map that close to perfect? A 10 deg difference in ambient temp would make more difference than an exhaust. Quote Link to comment Share on other sites More sharing options...

terribleturner Posted January 28, 2006 Author Share Posted January 28, 2006 Prefferably i'd like to get the mapping done after i get the exhaust, but im working on a budget and the thought that i'll get it AFTER getting her back on the road. I was just wondering if going from 3 to 4 inches will free up a bit more power to effect the ecu enough. Thanks for the replies. Quote Link to comment Share on other sites More sharing options...
CJ Posted January 28, 2006 Share Posted January 28, 2006 I changed from a Veiside 3" exhaust to a BL 4" version. No remap was needed. To suggest otherwise is bollox. Quote Link to comment Share on other sites More sharing options...

CJ Posted January 28, 2006 Share Posted January 28, 2006 Mieow guy's!! In Burt's defence this isn't in technical so any answer is valid If you feel any answer out of tech is valid (despite it being totally incorrect) then I look forward to seeing how you react in future when anyone else does the same. Or are there different "Alex" rules for different turbo buyers - or types of turbos bought? Quote Link to comment Share on other sites More sharing options...
JohnK Posted January 29, 2006 Share Posted January 29, 2006 Some people put a lot of weight into answers they get from this forum, especially those with little knoledge of their cars. If people guess or post up totally incorrect answers to valid questions this can lead to alsorts of problems from mild embaresment thru lost money to damaged parts. I'm all for technical discusion between people that KNOW or at least have experience with the subject and questions from those that dont. Posting up what your mate's mate once said down the pub just to increase your post count doent help anyone. Quote Link to comment Share on other sites More sharing options...

BURT Posted January 29, 2006 Share Posted January 29, 2006 how did you work that one out? OOps.. thougt it read get it mapped when exhausdt fitted, then a few months later get the BL system fitted ie turbo..thats why i sad fuelling different.

Clarkey Posted January 29, 2006 Share Posted January 29, 2006 Would a remap be required if the IC was changed ? For instance - a SMIC was replaced with a upgraded SMIC or even a FMIC ? I only ask because .. wouldn't a uprated IC give lower temps ? Quote Link to comment Share on other sites More sharing options...
CJ Posted January 29, 2006 Share Posted January 29, 2006 Changing the IC would not neccessitate a change in mapping. If that were the case then you would have to map for different climate conditions too i.e. summer daytime driving and night time winter driving.

Alex Posted January 30, 2006 Share Posted January 30, 2006 Most proper ECU's can "self learn". Piggybacks aren't quite so clever but with the stock ECU forever tweaking things they can handle changes in the weather and therefore changes in charge temperature. Lets make a list of the changes that could force a re-map (copy and add to) You'd only need a remap if you; 1) Changed the static fuel pressure 2) Changed the size of your injectors 3) Change the size of your turbo 4) Increased the boost pressure to beyond what has already been mapped for 5) Changed your capacity 6) Changed the compression ratio 7) Fitted WILD cams (mild shouldn't really require one but you could if you wanted) Any more for any more?

Wez Posted January 30, 2006 Share Posted January 30, 2006 I would say that although most minor changes do not require a remap, ie exhaust etc if you had the ability to change the map with a programmable ECU i see no reason not to tweak it as you may find some small gains. just my thought anyway Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted January 30, 2006 Share Posted January 30, 2006 You wont need to remap it mate You might just get slghtly better spooling up thats all Quote Link to comment Share on other sites More sharing options...
Wez Posted January 30, 2006 Share Posted January 30, 2006 Just to clarify I am not saying you have to remap but as I like to play with my map I would prob do it just to see what could be gained. Prob nothing but hey Quote Link to comment Share on other sites More sharing options...
