I'm not new to ECUflash but i am a little new to this...

I have a Boosted Lancer OZ and it was running off a bull **** FMU when i got the car. I adjusted the fuel and ignition maps so it would run a little beter and have been looking for a set of injectors ever since. Well the FMU recently failed on me and now i gota get the move on with some bigger injectors.

So what I'm trying to do is... increase the load from 100 to 260 on my fuel and ignition maps. I'm not asking about tuning the car but about how to get the ROM established so that i can tune it.


I know how to add the numbers but i was wandering if there is anything else i need to change as well for it to work correctly. I increased the number of collums on the load axis and adjusted the fields so that they read similar to an evo map in principle.

Will i need to rescale the MAF also in order for this to work? Someone told me i did but then as i read into it i get the feeling i don't have too. It needs to be rescaled because the trims are off but not in order to get the load correct is what I'm guessing.

Is there anything else you would suggest I should play with in order to get the rom compliant with boost?


More or less I'm just checking... i've normally delt with Evo roms where all of this is already done for you. I just wanted to make sure I'm not missing anything.


Thanks guys,

 

ahh this thread may help me, i need to add colums to mt map so that my tuner can tune it for boost

 

You most likely will need to scale the MAF. Comes with the territory when having hard intake pipes. Plus you added a turbo...so yeah....much MAF scaling is needed. The car should start and run though without scaling. Scaling will help to fine tune it. MAF scaling does nothing for load.

You can adjust the load values in the fuel and timing tables. You have a set number of slots to fill so you have to remove a value to increase another. There is a ton of how to info on it if you search. Pretty easy. Just set the value using = then adjust your table to make the 3d graph smooth. You should know how to tune.

 

I don't think you can add columns like that. You should be able to rescale the load axis on the fuel and timing tables.

I don't know for your application, but for the 3g eclipse there is a rom that is basically a evo 8 rom that can be flashed to a 3g ecu. Also, with the 3g you can swap to a evo 8 ecu.

 

you need to scale the MAF, its not fun.

as for increasing the load from 100 to 260, like the EVOs, you cant.
you can rescale your ignition and fuel tables, but you cannot add cells.

and are you saying you're seeing loads up to 260?

 

If you want to use the table at the same address/position, it is not possible to add cells to existing one as there is no room for it in the code.

However it would be possible to create brand new tables in the free space of the ROM and changing code references to new tables, but that would mean some custom coding work.

 

well lets get on this custom work man!!

 

I have not said that I want to do it
Moreover I have not seen your ROM yet if it is feasible (how much free room is available).

 

I think you misunderstood what I was saying.

No you cannot just add a cell. What you have to do is change a cell. But in order to change once cell higher you must lower another.

Example:

Evos have a max load cell of 260. In order to raise the load cell to 280 you have to shift the other load cells back to fill the 70 cell with the 80, the 80 with the 100, and so on. Then you repeat the process if you want to add a 300 load cell. Again you need to shift the rest of the load cells to fill in one that really isn't used.

Once you are content with your load cells, you need to repeat the process with the values in the table as they will now be all messed up from shifting the load cells and adding new (higher) values.

As stated earlier this link will explain it all with pictures.

I did a tune for ATR NA with bolt-on turbo, load scaling start from 0 to 100. Rescale timing table work just nice but afr is not possible. I ended up put extra gadget, air fuel controller to manipulate both afr and maf to get the car going boosting at 10psi.

 

Post a listing of the scaling values. I will give some insight as to what they could be changed to to try and get more load availability.

 

For your interest.

 

I was looking for the fuel and timing load scaling for the OZ guys that added turbos.
