Thread: Alfred.bin Needed - for N60 maf.

I believe Vadim said he corrected some of Calums VQ's that were wrong. I think the E60/N60 numbers were wrong. I believe Vadim said he got the correct numbers from the FSM.

yea.. not sure what the cons would be.. maybe gas mileage or throttle response or something.. i never have an issue getting my car in the right afr.

i'll be upgrading to a n62 maf soon i think which is much easier to figure out lol

ah thank you thats very helpful.. now only if i knew how to make sense of it all lol

im just going from whats in nistune guys..

can anyone explain the k value formula to me? u can't search k and value on the forum cause of the search engine.

try google

Not sure if this is what you want or not? Try post #3 in this thread.

i read that like 5 times and just realized where the b13 info was in that post.

so should the bin have 24271 has the k value then? and how does the maf relate to that?

I'm also curious about K value injector specifics. I have 3 different Calum "VE injector" bins with the same injector scaling and latency but with a different k value. Two of the bins have the same MAF but still a different inj. k value?? If I take Vadim's formula for B14 injector values I get a k value of 232. But the bins I have with the same variables for injector/maf have different K values of 250 and 274?? I don't get it!


Formula for new K Value:
(Old INJ Size / New INJ Size) * Old K Value = New K Value

In this example we take a stock B14 tune and add 333cc injectors to it.
(259cc / 333cc) * 298 Old K Value = 231.78 New K Value

Sorry for the thread jack BTW.

blackb13se-r: I got 24271 as the b13 k value as well. Are you using nistune? I am a noob with tuning for sure, but I remember reading JKTUNING said that the k-value affected more than just injector constants. Vadim said that the K value should be kept as close to the original number as possible for this reason? With Calum ECU's I am learning that you can only change the injector K value to adjust for diferent injector sizes, but with NismoTronic you can adjust in other ways?? How does this apply to Nistune?? This is way beyond my tuning knowledge so just going off of what I've read.

calum explains it here.
