do all novas run from an engine management system ECU?

[20SEHnova]

i had a 1.2 carb and wasnt sure. wanting to buy a 1.4 sr carbed aswell but just wondering

[Philsutton]

no the carb ones did not use an engine management system, only the injection ones do like the GTE/GSI and spi

[20SEHnova]

hmm thats interesting then isnt it :) does that mean they dont have a engine wiring loom aswell then?

[Adam]

No, they just have a smaller loom.
The coil/dizzy/coolant temp/alternator/oil pressure etc still need wires.

why then does the mk2 (Up to K -93) 1.4 sr engine run off carb with no ecu, but have a catalitic convertor, does it not have a lambda sensor then either?

[Philsutton]

it doesnt, easy mistake if your not into your engines. The 1.4SPI looks like a 1.4 carb but is slightly different (looks wise that is) the carb wont have a cat an the spi will.

[Adam]

As phil said.

No carb engines have a lambda or cat.

[20SEHnova]

oh, hmm but i was told on here all nova srs have the carb engine, even the mk2's which run up to 93 so does that mean they didnt have cats?

[Philsutton]

all sr's did have carb engines, the sri however did have a cat and is normally what would be a 93 car, but there were some sr's made at this time.

[20SEHnova]

ah i see ok ty =]

[Adam]

Aye, theres a couple of K-plate, 1.4SR's.

[20SEHnova]

h j k and l i presume? not just k?
