Hi, and welcome,
what engine,
1300, 1500, 1600

the BASIC EFI is relatively simple, like panda + Uno

for a better system you would need,
ECU, electric fuel pump, lambda probe, etc

got any photo's of the Regata..??

Re: Carb to EFI conversation Motronic SPI

pretty sure the UK didn't see a '70 after 1987..,

so may be quite different mechanically,

Re: Carb to EFI conversation Motronic SPI

Ya , may be . I bought it in Italy and now I am in Esat Africa .
I got a magnitti marrilli IAW 16F C4 ECU with harness do you think it will match the car ? Meanwhile , if I want to remap the ECU ,do you have any idea what chip they are using and tuning software ? B/c as per my research I might need to add some fuel as it might run lean .

Re: Carb to EFI conversation Motronic SPI

No I got the ECU in a very good price while I also got the xdf file to tune it with tunerpro but on the factory installation they use power latch relay which energizes while the engine is off , should I use that or by pass it ?
