I am fitting a set of tubular headers and decat down pipe,also an eprom remaped chip into the ecu, is this ok, or does this cause any issues?Do I need to go on to a rolling road for a more exact remap??? thanks guys.

 

no ideas>???

 

no body got any advise on this for me

 

there is tons of stuff on the site about this , its down to you , if you want the most out of what your fitting to the car a remap is best !(as long as yours can be mapped ). but at around the 3-500 depending where you go its allways best to do most ofyour mods then get it mapped unless you upping boost orchanging injectors etc etc as they could cause engine damage with out the propper aet up .

 

Because of the headers, yes - the ECU will be able to cope with the increased fuelling for the decat, and boost control can get a bit 'spikey' but typically isn't too bad. However, the headers can change the engine's VE significantly in specific places - which the ECU won't adjust for - so that really needs a remap.
Hope that helps.

 

what is the chip mapped for?
who mapped the chip?

 

The tubular headers will probably result in slugged spool.
Finish the mods you plan for now and then go for a remap. Several people to choose from not too far from you or even who may travel.

 

I am now halfway through an engine rebuild! comp bearings, comitec gaskets,forged pistons,exdey clutch,can you tell me who the good mappers are around here?Thanks Harvey.

You could have a word with Bob Rawle who could offer you a couple of solutions depending on what you ultimately want to achieve. You could also speak to Simon Roe (JGM) who will do similar ECUs and will travel.
