At the moment I'm awaiting the return of my engine as it's away being rebuilt as a 2.1 stroker my question is, when I get it back would I be able to run it in on the standard ecu?
It will return as a 2.1 stroker with a TD0520G & 740 injectors and have a 3" cat back system installed as well as either a decat or sports cat downpipe & walbro 255 pump.
I'm hoping this might be possible as I also have an FMIC, Simtek ecu, fuellab fpr & induction system to fit but would rather fit all this then have it mapped to full power once it is run in if that might be the best way to do it? Just trying to think money wise here so I don't have to pay for 2 remaps if possible.
Advice from people who have done this or do this would be appreciated please.

 

I recently ran in my 2.1 with out a running in map and all was ok, nothing else was changed from the previous spec though.

From what I gather your changing your injectors and turbo/exhaust at the same time, if so me personally I would get it mapped.

 

Cheers Dunk aye I'm thinking I might have to bite the bullet but my location doesn't help for ease of getting the car to someone who can map it either. What about if I disconnect the actuator arm so it can't create any boost to keep things on the safe side?

 

the best way of controlling boost is your right foot!

Either way you will still have a set of 740's spraying in way to much fuel for the standard map.

 

My right foot has a mind of it's own sometimes.
Aye fair point
