Replacing ecu

[dandan]

When (and I'm certain its gonna happen now) I replace my 1.2i lump for a 1.6 do I replace the ecu for that of the donor engine?
Sorry still learning! :D

[burgo]

yes along with all the engine loom aswell

[dandan]

Forgive my igorance but what do you mean by all (maybe I should have burgo's title?)

[burgo]

well i supose it depends what you plan on using with the 1600?? injection, carb, twin , carbs or of course throttle bodies??

Turbo! Going the whole hog!
But wanna try and do it myself..............

turboing a N/A engine is not something that u can easily bodge together and hope it will work

2 big problems u need to overcome are

1. extra fuelling for boost - std ecu will not handle this in any way so u will need something else - either a 5th injector or a fully mappable management system

2. compression ratio - std 1600 compression is 10:1 which is to high to run any kind of decent boost - u will need to fit low compression pistons or bodge it with a spacer plate and 2 gaskets

Decided to opt for 1.6 16v.
