CE Lancer ECU tuning

If I recall correctly, despite having the same hardware, our rom is very different to the evo rom. We only have about 25% leeway, as 12.5%+ and 12.5%- to play with.
The reason being the evo rom uses different memory areas on the chip for its storage of data, and if we used the same areas, our data would be spread out a lot more as we dont require all the space as the evo does

I’m not sure if this has been discussed or mentioned in particular but thought I’d share.
4g93 H8 ecu’s have been used to control 4g94 motors in the past, nothing new, but what I found recently is that outlanders and pajero io’s with 4g94 come factory with H8 Ecu. Quite possibly a very easy way to make your 4g94 swap in a ce work first hit would simply be to flash the outlander or pajero rom.

still reaearching further into g69 ecu and roms for outlander. I was hoping they may have used a more tuneable ecu platform, but for now it appears to be the same as CH lancer

Interesting.. So you'd run the Outlander/Paj rom with the map info from the g94? How come the normal g94 rom cant be run in a CE (maybe im just having a mental blank, i dont know why?).

The SH ecu platform is substancially better of an ECU, somewhat because of the live-tuning aspect. Faster, more memory for settings, and a few other bits and pieces. The H8 series engines can run on the SH with only a handful of wires changes.

So what your saying is IF I got me a modern outlander ECU and swap a few pins I can have better control of my engine when I pressurise the intake system?

Also, this brings me to another question what differences are there between the 93 and 94 ECUwise? like does it have Knock control to worry about or is it just a bigger capacity 93?

93, 94, Outlander and Paj ecus apparently are all the same, they have the same Rom space and processor. The next gen after this, the SH ecu, has much better everything.
It's the amount of info within the rom/definition that will give you customisation - a good example is to look at the 4g93 rom, and look at ceddymods evo5/6 rom. They run off the same ecu, but the ceddymods definition uses a tonne more of the ecus capability. Ceddymods uses a knock sensor, so in theory it's possible to install on a g93 (the cm5a uses a knock sensor, so its definitely a thing, or at least was at some point).

I mean EVO's run a knock sensor how else would it know to switch between Hi and Low octane and there were some 93's that had them I have a wiring diagram for a 93 with a knock sensor (buggered if I know what it came out in but still) :) so is the ECU I am running limited by the ROM or the Hardware (chips) itself?

Exactly. The OEM AUDM 4G93 ROM just simply doenst have the coding within the definition to utilise a knock sensor. I guess you would be able to copy paste some of the code from the CM5A ROM to trial it, but careful not to brick the ECU
