Nope. Once all the pointer are right or however the programmers does it, no.

But room must be made. I am not a programmer, so those with skills can better reply to you.

At least on the DBW ECU, it wouldn't be that hard, but you'd need a tool to automate it to keep it from taking hours and reduce the chance of error.

You need to shuffle the maps a bit. There is room. The map configuration allows you to just change the map definition line to do this.

I still don't think it is that important to do.

westminst, i think you're overstating the need for additional resolution. in the higher load areas there is no reason to require such fine granularity IF the map is properly constructed.

Also keep in mind the ECU does a bilinear sample on the 3D maps, and a linear interpolation on 2D maps. It isn't a step on the map. Basically it does a weighted average of the four closest samples.

So if your timing drops like a rock at 2600-4000rpm at about the 1.5 load level, your timing does not actually suddenly drop 5 degrees. It smoothly falls down the slope between the load and RPM columns.

just learning here

if i wanted to run 30-40 psi boost

how far would the maf allow me to go?

all i could rescale to was 8 what power/boost would thei realate too?

is it as simple as making a new larger dia. afm body and fitting the sensor to that?

i do a lot of high power wrx's but all have been stand alones fitted how far can you take the std system?

thanks
