Hi

You'll need to adjust KRKTE

I know from my BAM stock injecotrs are as you say 383cc and Audi set KRKTE at 0.08347 pretty much for all 383cc injector cars that I've seen. I also know my car now running 550cc injectors runs well with the KRKTE at 0.07248 so I would say for you to run the car you'd need a figure in between there. The best way I found is to start with a figure, run the car, log 032 and then adjust the figure depending on result ie +/-.


It just so happens that 383+550/2 is nearly 443cc so a good ball park figure for you would be to set KRKTE at 0.08347+0.07248/2 = 0.077975

Now if you take the KRKTE ballpark figure equation of 34.125/injector cc/min

you get 34.125/443 = 0.07708 which is nearly the same

with this in mind i'd start with something in the middle say 0.07745 and run the car and log 032 and see what you. you may get it spot on or it might need a tweak but either way you'll be very close and the car will certainly run ok.

I think you only need to adjust TEMIN if you have issues with the idle lfts. I also thought that it needed to be changed if you changed the injectors and the latency was different. If you run the same injectors the minimum opening time will be the same, I could be wrong though,

Best to try, log 032 on vcds and see what the trims are like.

The 34.125/cc is just a ball park guess, nothing accurate but gets you going. There is another formula which works it more accurately and if you search krkte in nef you'll find a couple of threads re it. I've got it written down but from experience while it's good it's never accurate because different engines run differently if you get a rough figure you can then adjust and fine tune once you are able to log 032
