Not sure if this has been asked before. Kinda thought it would have been but couldn't find anything on search.

Anyway, having never seen a MK2 1.2 under the bonnet, is the MK1 1.2 8v SPI similar/identical to the MK2s? I.e, did fiat revise it at all when they produced the MK2? Will MK1 engine components fit the MK2?

And finally, will a Mckrich chipped 1108 ECU work on a MK2 1.2 8v?

Cheers.

the mk2 has a rolling code immobiliser so i doubt the chip will work., i think i remember hearing that the mk2 engine has a lot of the mountings for stuff in different places but the engine is pretty much the same other than that.,

hmm.. any ideas if it would do any damage if i tried the Mckrich ECU?

as far as i know it will only work on the mk1.,

i thought the mk2 engines were mpi, producing 60bhp and the mk1 engines were spi producing 60bhp, may be wrong though, but sure i read that somewhere

The mk2 are closer to 60bhp than they are 75.
The mk1 has more power due to a few changes...
I guessing the mk2 doesn't use the 866 cam...swapping it for a less agressive cam set.
The ECU probably has a few difference in how it controls the injectors.
Possibly a more restrictive exhaust as well.
There was a topic about this a little while back...DavetheTrike had some inputs into what changes were made...so he might be able to clear it up a bit
