Like I said, I find it perfectly understandable that people limit the map to 2.1 bar where the 3 bar map sensor runs out, even though I wouldnt personally what to do that on any ECU I was mapping speed/density, I would just use an appropriate sensor (which as I tend to map stuff like autronic is simpler for me I realise)

What I was saying was REALLY bad practice is to have the hardware in front of you to go upto 2.1 bar and then only go to 1.87 bar, what possible justification can you have for that?
I know that there is a finite number of breakpoints but if you are running to over 2 bar then you should still make the top one the full extent of the map sensor, that is just blatant.
Thats what I was calling pure laziness and bad mapping, going over the sensor value is a spec decision and hence as much about the customers choice as the mappers, but choosing to just ignore the top of the sensor value is just piss poor mapping.




If they are mapping around hardware limits imposed by the spec thats presented to them for mapping then although thats not ideal, I can understand why they are doing that as they have no option.






Its an age old argument, but the difference is that Stu etc are taking the original calibration and making specific changes to it to suit a particular car, where as you sound like you are just copying and pasting in chunks of other maps till its about right.
So in the context of a music analogy, he would be professionally remixing two songs together by dissecting them and matching the beats etc to merge together, and you would play 2 mins of one song then 30 seconds of another then 1 min of the first one again.




I can give you a very specific value for that. Its exactly ZERO mate for that specific combination of hardware and software, and yet I still seem to understand the basics of doing so like putting the break points in suitable places better than you guys. Which shows how much of this discussion is just about general mapping rather than being so application specific as you seem to think it is.
Bottom line is, that it is just good mapping practice to use appropriate break points and got naff all to do with what software you are using to map with.
So for example when I have mapped L8 on RP Labs or an autronic SM4 or an omex 600 or whatever else, I have exactly the same choices to make about where I set the break points as I would if using the software you guys are using to mess around with your antiques
all spot on

it's not even difficult to write the breakpoints in correctly. i wrote an excel file once that can read in the binary file, you can change any breakpoints or map values in excel and then save it again in binary format to be burned to a chip. the weber files are that simple (until you get involved in checksums etc as stu has already pointed out)
