182 ecu in a 172

[Eckascliovalver]

this really is just a random question and most likely sounds silly



What would happen if if a 182 ecu was used in a 172 along with the 4-2-1 exhaust manifold?

Any gains or downfalls?

I used a 172 ph2 ecu in my 182 for a while. It worked, except for the cc and speed limiter. So I think the 182 will also work on a 172. Not sure

Depnds some ECU's won't work as there s a few types.

downfall is you need the uch and key aswell from the matching vehicle

ahh i see, so there wont be much gains in power then?

Can have it cleared or use anew one.

there are a few techy reasons as to why you cant just 'swap' - immobiliser etc but essentially your saying use a 182 map on a 172 - well yes u can.
from speaking to pete at bellautos when he remapped mine, the fuelling and timing gradually got more agressive with 172 -> 182 altho my late 172 was somewhere inbetween (it has the rs manifold and 182 ecu as standard) altho at some point you obviously pass peak point and start to go back again which may or may not happen without checking on a rr or via live monitoring

You thinking on doing the manifold bud ?

Or aint it worth it without the remap ?
