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
 
I saw something mention within the thread but just confirming, I can use a plastic ECU in my metal case ECU lancer,

I'm wanting to get the plastic one reflashed and immobilizer deleted so I can simply switch between stock and flashed

Haven't read of anyone trying this just wanting some insight

Yes but the plastic case will need a whole retune. The plastic and metal case ecu's can almost be considered generations different - they used different models for their major sensors, so all of the axis scaling of the maps are different. Kind of like trying to put Windows 10 on floppy discs and install from that. Its definitely possible, but not without some little bugs.


Also, has anyone taken apart the ECU to fix bulging capacitors? And has it fixed idle issues and such?
Its generally easier to change the faulty sensors than to change the caps on an ECU, but of course its all skill-set dependent. I've known of maybe 2-3 ECU's failing, compared to dozens and dozens of sensors (MAFs, TPS, O2, etc etc).

So it would be better to download the .xml file off the metal case and transfer that onto the plastic case to be able to customize the variables off that one

That would be the first step yeap, but its a rescaling of every axis that there is to make sure it runs right. Copying across the scaling from metal to plastic may still have a couple of figures that dont line up perfectly (e.g at the extremes of the mapping like very low/cranking RPM), but it can be done.

So save both files and manually rescale everything appropriately would be the best way to minimise faults, time consuming though

So I think I may have killed my ECU and need to try and either replace it with stock or upgrade to something else (read: Haltech, Adaptronic etc.) Thoughts/input? Also want to keep my AC etc so not sure how many inputs/outputs I would need HELP!!!! Feeling stupid as my brain is MUSH from uni!
 
Evo 5/6, and CM5A Tuning files:
I had to jump through a few bloody hoops to find this:

The OEM CM5A ECU mapping.... That noone picked up i didnt actually attach to my post in the first place lmao.



You can use this file on any stock plastic case ECU (!As long as you confirm the chipset type first!) to have the car run exactly like OEM turbocharged cars are

This is what I thought, but I assumed I was just missing something…
 
Hey everyone. First post. I apologize for reviving and old thread but I'm desperate hahah! Hope you're all having a great day! SO.

My issue is I swapped a G93 into a G15 USDM Mirage using the stock G15 harness and ECU with the distributor and everything. It's a 1998 plastic case. It probably would've run okay if I hadn't also installed a camshaft and G92 MIVEC Pistons aaaand a 70mm throttle.

So it runs like doodoo. But I can't for the life of me find a definition for the G15 ECU. Am I missing something? lol Halp me make 200hp pls-

Search up the ROM ID or chip ID on google. You may have some luck. Do you have an AFR gauge?

also do you have a picture of the distributor setup? I’ve never seen a usdm 1.8l with distributor

I sure do! It's running at 18s on idle. :'3 Any gas and it backfires terribly. Thank goodness I got dem forged rods HEHEHE-

Also, you just remove the whole cam position housing and the dizzy from the 1.5 slots right in! It's keyed the same way and everything you also need 1995 1.8 spark plug wires and finally tap a hole with a fitting into the intake for the MAP sensor on the firewall and you're pretty much done. Everything else basically bolts on. I'll take pics of it for you soon~! I'm even using a 1.5L flywheel and just redrilled it to the 7 bolt of the 1.8 (Factory lightweight flywheel woo!), 1.5 clutch and trans.

Anyhow! I'll definitely take a crack at searching up the IDs, I didn't think about it! Will report back my findings (If any. qq)
