A Question S1 And S2 Stock Ecu's

[Pal]

i had a manual conversion done a couple of years back now but left the auto ecu in there with a safc2 piggyback. now my power levels have increased from stock(about 290hp with just about all stage one modes done), i am thinking the ecu is not the best thing to have as i seem to be very flat midrange in my power curve. i have decided to buy a manual ecu to see if it helps but i am wondering if stock s1 and s2 from r33 swappable? i have added my dyno sheet to see if anyone has any other ideas.

yes they are swapable. Will it fix your problem ?? NO. Time to get a aftermarket ecu and all your problems will be solved. The greddy emanage blue is GREAT for your application.

I am led to beleive there is a difference between them.

Also between mine and friends S1 engines, there seems to be a difference between 93 and 94 model engines.

I have a 94, all the guys have 93s, and my ECU just runs like a dog on there engines.

the map data and chip is different between models (including the same series)

if you get the wrong model of chip the car sluggish (as matt said) and is a pig to drive

the engine works fine and runs ok, just drives like poo

get a aftermarked piggy back or plug in. fix the problem properly or you will waste more money with band aid fix's. been there done that.
