I'm starting to get into the 270's+ now in my load and my current maps only go to 260. I was curious what other tables need to be changed other then the fuel and timing tables when adding a 280 and a 300 load column? also what are a good base settings to start with in these columns? do I just go into edit map definations and change the x-axis elements from 18 to 20?
thanks,
ed

I offer load scaling in one of my tuning packages

 

I have not heard of anyone adding an extra collumn, sounds like a good idea to me. Jack, what do you think, can the ecu handle it?

 

Almost every 8 thats modded has rescaled the load columns

 

c6...
I think the process is to remove a lower load column and add the one you want.
the net is you have the same number of columns, only replacing one for another.

 

A rescale is not the same as adding an extra load column. Adding a load column would be a significant amount of work, as the maps would have to be moved and the code rewritten to take the new locations into account.

I am also puzzled by the statment "Almost every 8 thats modded has rescaled the load columns" How do you know this? Have you seen all these maps?

Not that I am gonna start poo flinging but there are a few things I would like to say:

Charlie is right. A good portion of all the VIII's I have seen maps posted here or have tuned personally have been rescaled to some extent. I agree that adding columns while a "neat" idea would be SIGNIFICANTLY harder than just rescaling.

Charging extra for 2 minutes worth of work that should be done to properly tune a car isnt unethical, but questionable. Its your business, but on an VIII especially I rescale to 300 or 320. IX's can hit 290 (2byte, since its the only measurement that matters) on a stock turbo and in good air I have hit 305-310.

just for the info, what does the ecu do when you go beyond the map? does it extrapolate from the existing?

 

Correct, if your map only goes to 260 load and you're actually hitting 270, it's going to use the values from the 260. This is a non issue until you start going well beyond 260 and that's usually when you're running cams or a turbo upgrade on pump gas when we're talking about EVO8's.

 

saying that you're not going to start slinging poo and then doing it anyway doesn't make it any less smelly in here.

I'm running a business and customers aren't paying for my time, they are paying for my knowledge. The extra load columns aren't necessary for most people so it's a non issue. Those that require it are happy to pay for it because they don't know how to do it or don't trust themselves to do it correctly. Sure I could make one price for all tunes and include everything but it would be so high that most people wouldn't be interested. I have different packages to fit different needs and budgets. Thanks for your concern

 

The poo flinging comment was directed toward Burgers ( I didnt want to ruffle His feathers).

Paying for expertise is what makes any tuner worth their fee. My comment was directed more toward the fact that to properly tune most of the VIII's currently in service require being rescaled to begin with. I look at an initial log before I suggest what is needed anyway, if you do that and realise that hey this guy doesnt need a rescaled map then cheers to you.

Anytime you are off the map the car extrapolates on a rapidly deteriorating curve almost like how the timing will behave when the car is riding the knock control to achieve "best timing". For example in a IX, if the car is above 7K (or the last scaled RPM entry) MIVEC drops to 0* advance.

adding extra resolution isn't THAT hard, basically:

1) find new location in ROM for your load axis
2) find new location in ROM for your 3d maps that reference this axis
3) update ROM hehe

probably all of about 1 hours worth of work...

 

Do you have examples of this being done? It would be nice for the VIIIs if you could get the 2 extra columns on the IXs without losing any columns.

 

no, but if i have some free time, I can do one up for you to see...
