Confirmed: Evo ROM Can Be Flashed to Lancer ECU

I would like to point out looking at my rom, there is a drop of 5-6 degrees of timing in my map between 90 and 100 load cells and it happens from 2000-3500 rpm range and the 16 count knocks were at 2300-2600 rpms at 96% load but cant see how this would trigger this kinda of knock count especially since this is how its been for awhile now.

About the transmission issue ...
How different are the Evo and Lancer auto transmissions? From what I know, the Evo VIII ROMs have some random bits of code for the auto versions overseas, even though they weren't offered here. No reason to reinvent the wheel. Any chance those might control the same things as the Lancer transmission tables?

.We can also adjust the knock sensitivity if you can confirm that the knock is just phantom noise. Take a log of the knock sensor voltage and look for spike events at the time of the knock event. If the noise is just ramping up past a threshold we may just be getting false knock.

the gta uses the same invecs system as the lancer but it is a 5 speed whereas the lancer is 4 speed
also the gta uses a semi manual shift option whereas the lancer does not...
The only work around is to swap in the lancer manual trans or add the whole coding for the f4a42 trans into an evo rom which I may try ...

Try knocking some timing down just in front of the knock event. Large changes in timing seem to provoke the knock sensor more with the evo not sure if that will apply here .
We can also adjust the knock sensitivity if you can confirm that the knock is just phantom noise. Take a log of the knock sensor voltage and look for spike events at the time of the knock event. If the noise is just ramping up past a threshold we may just be getting false knock.

So how much of a spike should I be seeing with the knock voltage?, I have my latest log on the evoscan graph and I cant see any kind of graph spike where my knock counts are spiking. To be honest though maybe I am not the best one to decipher this maybe I could send you this log and you could take a look at it if you dont mind RoadSpike.

+1 I bought the same manual senate has to download and I never have been able to find the darn thing.

Sure do it has been sent. I have been doing some research on this and I guess we would have to know if the evo and lancer engines share the same frequencies for the knock sensor to be accurate. I looked through the evo rom and the lancer rom. Evo's knock filters are alot bigger and have about twice as many filters. The filters that the lancer does have sure seem to be setup alot differently than the evo's but this is all new to me so idk.

I get the feeling its as simple as the ISCV variables not kicking in properly and may be even as stupid as a periphery bit that needs to be enabled for it to work. The Evo rom is clearly derrived from the lancer base rom with adjustment tables added to the code.
It seems unlikely they would scrap the whole code to run manual vs auto. I'm betting here that the evo rom contains the code needed to run with an auto tranny but isn't correctly setup.
