re-build re-map
im about to get an engine re-build on my 02 wrx . current mods are pinks,vf34 turbo,full de-cat,up pipe,fmic,induction kit,and walbro fp.
after it has been re-built i will obviously have to run the engine in , so is it safe to drive around without having it re-mapped ? also i have had my car re-mapped in the past so will that be re-set
apreciate some help quite confused by it all ! thanx
cant wait to get bak on tha road

As long as your sticking to the same set up you had before the rebuild it should be ok. if your replacing a 2.0l with another 2.0l it will be ok, but if your replacing a 2.0l with a 2.5 then best see your mapper TBH.
Dont know what you mean by reset? but the previous remap should be fine as well if thats what you mean.

thanks for reply mate i just thought that i would have to get it remapped again after the rebuild ! i dont know much as far as mapping concerned .well that sounds cool will get it mapped again after anyway as last time it was mapped one of my piston rings was blown 
no-one knew why it only made 301 bhp until it started chucking clouds of smoke out the exhaust a couple of days later

definitly worth getting it checked, the reason it failed before could still be there and it is a nice way of confirming it is all back together and running fine now and when you have just paid out for a rebuild it is a good way to ensure your investment is safe etc.

loli wasnt there on the day , but i had work done by tfs racing and stuart took it to surrey rolling road for u to map it ! stuart said that u thought it was gonna make about 330-340 on rollers and was unsure why it didnt
i was on your website last night thinking of gettin it mapped with u again once its re-built, can u tell me how much it will cost , and will it be safe to map it straight after the re-build or will i need to run it in ? thanx:cheers for your help

Oh yes I remember the car.
in my usual check around under the bonnet I found the fuel pressure vac hose had a split.. and replaced it.. was worried at that point because it would have been running lean etc.. but all seemed okay and no obvious issues other than as you say it only made 301bhp and engine was noisy but nothing untoward.
Obviously the ringland was gone already hence the low power but must have been early stages.

As a general rule, you won't hurt an engine in the running in phase even if it hasn't been "mapped" specially for it. Assuming it hasn't got ridiculously aggressive ignition set at medium load and is detting on part throttle that is.
Nobody blows engines up if driving at the speed limit sensibly! What tends to kill new engines are things like unnoticed water and oil leaks. If it runs reasonably well, the chances are it'll be fine until you're good to go.
Any professional organisation will test a new build thoroughly before it leaves.
