Performance differnce between a 2.0 ecu and a 1.8 ecu

[warp21]

I've heard that there is a possible performance difference between the 2.0 ecu and the 1.8 ecu, the 1.8 being better. I know the 1.8 intake cam has a small performance advantage but what about the ecu, can someone shed a little bit of light on the subject? I've searched the forums for 1.8 ecu but it errors out and I don't know what other terms would be related.[oh and sorry about the spelling I meant difference]

in a nut shell it makes the 2.0 run leaner. this only works for rd/rd2 tibs and j2 elantras.

So you are saying better gas millage is the only performance advantage?

[thegrim]

the leaner the better in most cases. not saying lean it all the way out. but when trying to reach stoich, u want to be leaner than richer to it if that makes sense...

Grim's right, if the 1.8 has the 2.0 motor running leaner then gas mileage and power will increase.
