Running in a forged engine with old map

[Turbo Goose]

Hi guys, once my forged engine is built im wondering what to do to run in.

It currently has an emanage blue mapped on a tf035 at 1.1 bar.

I have a td04 and 420cc injectors whoch i want to get the car mapped on when it goes for mapping again

My question is, if i keep the standard injectors and TF035 (which the current ecu is mapped to when it had standard engine) would it be ok to turn the boost down for the running in period? Then once its had a few 100 miles on it, fit the td04 and 420cc injectors and take for mapping is.

My worry is that the current map wont match the new set up exactly but would it fuel fine at lower boost?

Thanks guys, dan

Is it hard wires or on. Pnp loom.? Ull be fine either way running it on stock boost and the correct injectors for the map I'd certainly advise getting a wideband regardless so you can monitor your afrs

Its hard wired dude, not sure how emanages are wired in, guessing they are in series so disconnecting it would just cause open circuits.

I'll just lower to boost to .5 or something

Definitely going to purchase a wideband

Yea if its hard wired in to much Agro removing it. Just keep it at stock boost fit the wideband and keep an eye on it should be fine as long as you drive sensible

If you just take it easy it should be fine until you get the map tweaked. Most engine failures happen at WOT.

if its isnt boosting it will feul fine just stay out of boost til then !!!!

just kep the injectors its mapped on dont change them attal feuling will be way off then

Been reading on running engine in and apparently you need to give it some boost so the rings come under the sort of pressure/forces in the first 100 or so while the miles as after this the bores with glaze. So that whilst the bores are crosshatched/unglazed it can 'cut' into thr rings

Think theres big debate on whether an engine should be ran in gently or given some stick so dont start a war please haha

you do that on first startup procedure not under load !!!!!! thats just my way ha ha

The engines not under load if the car is in neutral

I would speak to whoever built the engine and ask them what their recommended break in procedure would be to void any warranties if given.

I wrote a running in procedure a little while back, have a search for it
