do i need a remap after engine rebuild

[tdi-man]

engines had new head fitted and new piston rings shells etc etc

do i need to get it remapped again ?

thanks

if you had a map it will still be there in the ECU

Well surely your engine will run better now so you'd have thought you'd possibly be able to get more out of it now - so id suggest yes.
maybe wrong tho

 

[tdi-man]

lol i know that just wonder if i need it checking

 

[hades-]

it wont need checking
rebuilding engine wont change the map.

Of course the map hasnt changed but in theory the engine has

unless its a full on custom map it would only be the ame if it was reflashed

 

[tdi-man]

it is a custom map with a hot start fix in the map and i was wonder if the hot start probelm was down to the fact that the cracks in the head are in the glow plug holes

dont worry about it
so you have a stage 1 remap
i ment a full on big turbo stage 3 custom map
it will be ok

 

[tdi-man]

i do have a hybrid turbo with full egr delete

 

[hades-]

so i take it you still have ther same set up nothings changed
then you should be ok
but by all means spend some money for the fun of it
when i had my stage 3 rebuilt with new cams and head both times the map was still the same

i was wondering if mine had a hot start fault ie not start first turn of the key when hot if these cracks by the glow plug holes might of been the cause ?

so i could get the hot start mapped out

Map is programmed to ecu so should be all there but worth getting it tweaked for your new built engine as all components are new and will be working much smoother that way you might get more bhp

You say you had a hot start map done so was the hot start rectified with this?

I also have had a hot start map replaced/tweaked and mine has been brilliant, neither the starter or battery has been changed. (Anyone with a hot start issue should unplug the temperature sensor located under the fuel pump when at operating temperature and start the engine - if it fires up just as cold, the starter nor the battery are at fault - it's the software in the ECU)


Oh, and your Remap will stay on the ECU, I fail to see that getting it tweaked because the engine is rebuilt will bring any gains (apart from being stronger/last longer!) Just remember to 'run it in'!
