Thread: Tweeking a TDI

Fuel pump re mapped??? confused me How is this done on a 300TDi?

I'm in the process of sourcing a 3" mandrel bent straight through system and a bigger I/C See Jase this forum) and a EGT gauge, then I will employ Rich (KIE4) to do the adjusting for the extra ponies. but re-mapping sounds electronic and I don't have that on either of my 300TDi's.

mmmm its like i said i'm a chef .
Thats what the boys at les richmond are doing there putting a kit in the pump maybe they just said remapping because of that i'm not to sure what they ment but thats what there told me mmmm i'm a bit worried now what there charging me for .... i'm sure it all above board

LRA are experts maybe someone else Here could jump in and help..Anyone???

its the equivalent of remapping an ecu.......they will tweak the injection pump which will give the extra ponies.....

a bigger and better more efficient intercooler and bigger exhaust will make a difference.....

the intercooler will give more ponies as it cools the intake air better and therefore you get more
air and fuel into the combustion chamber......which gives a bigger bang.....(good thing)....

and the bigger exhaust will help to get rid of the bigger bang easier and faster.....making way for the next big bang....
it also alows the turbo to spool up quicker...or should i say lower in the rev range.......
due to less back pressure......this means less turbo lag.......


now...with the turbo and everything working a bit harder....i would also invest in some type of turbo timer......

err...the answer to that question will be the info you are NOT looking for....

i will let others answer that one......

could I respectfully suggest you do a search of the tech forum as all your questions have been discussed in depth.....

i was told the last of the 300tdi's HAD ecu's for fuel...

hang on this is a 97 model. but still a bit of info.

oh..... 3 inch mandrel bent exhaust with one straight through muffler. as this will drop the egt's you can turn up the fuel a bit.... i would not turn the boost up they already run about 15psi.
