Turbo engine can work without ECU?
Turbo Mini Forums

Hi,

I'm a recent member and i have some difficulties

I have a 1275MG turbo engine from 1985 to fit in my mini, but i dont have de ECU.

Does the engine work wihout it? how?

I'm from Portugal and here I cant find one ECU.

Thank's

Carlos

Yes it will work but you'll only be able to boost to around 4 psi IIR.

Once the engine's past it's peak torque range the ECU allows the boost to increase to around 7psi, meaning more bhp at the top of the rev range without the gearbox-killing torque that 7psi would create at 3000 revs.

I'm sure others on here can advise you about alternatives for the ECU.

I don't know one engine with one! LOL

Basically the ecu and its bits are a fancy bleed valve which controls the boost solenoid. Replace the boost solenoid with a bleed valve and remove the ecu. Block up where the ecu was. Job done

make sure you fit a good boost guage so you know how much boost you are adjusting to

no longer a series, but still 1.3 turbo.
