Default New engine in, now car running poorly

After my engine went, I've now put my forged 2.0 block in(same heads)

Cars now running, big smile on my face when she came back to life

Am I right that it should be running low power until I remap her, as the engine light comes on when I put my foot down. Think it's in limp mode or something, new lightweight flywheel was also fitted.
Stalling and revs dropping too, any idea if I can get a fault read on a simtek, or just go straight for the map
Many thanks

It's not boosting (well very little), as the engine management light comes on at around 3.5k revs

Firstly, the compression will be different, the map will need altering.. along with the fact everything has been undone and done back up so it would be wise to get it checked.

engine light at 3.5k - has the ecu been altered for the engine? simtek only uses the engine light for 3 things - as part of the map swap between maps if not on a switch at key on, as a shift light solid lit (rpm setup in the map) as a knock warning (will flash).

there is no limp mode on a simtek.

Looks like it could be knock warning as it flashed a few times
Just spoke to Neil so he can have a quick look over then a map

Did you check for valve damage if you used the same heads? You didn't mess about getting it up and running

Hope you get it sorted soon
