Forged engine on standard ecu??

[JordEP91]

Hello, this may have been covered, sorry if it has,
I'm looking into having my engine fully forged but will I be able to run it on a standard ecu till I get a piggyback or standalone ecu?
A few friends have said yes I can still run it on the standard ecu and some have said no, so I thought I would post on here to get your advice on this??

Yes you can, but I would advise that the base ignition timing is reduced from 10 BTDC, to around 6 BTDC to ensure that the engine remains safe from knock. Also to ensure that the AFR is spot on, or slightly on the rich side for your setup. around 11.2-11.0:1 would probably be around what I would like to see.

Thanks, yeah I will do that, but hopefully if everything goes to plan I will have a piggyback at the same time,
Thanks again Adam!!

You will be fine running it as is.
Run it at standard ignition timing and you will be fine.

Depends really what else you are doing. Fitting a bigger turbo? Bigger injectors? More boost?

If on a stock turbo, then you will be fine with stock boost levels, so long as things are checked to be running as they should.

If running any form of a larger turbo, I wouldn't risk damaging the new engine and drive the car off boost until you can afford to get an ECU fitted.
