If I'm swapping the VQ table on this stock U13 bin, would I use the Z32 Calum table? Then after I modify the VQ Table, what is the formula for the K value? And what do I need to change on the TP scale?

And what is the "feedback control flag"?

Calum VQ table is what Calum uses in his Z32 maps, it's incorrect so I should remove it actually.

Feedback control flag is o2 sensor and knock sensor feedback

I let the software do the base calculation (Nistune)to get the K close then I adjust it realtime to get it perfect.

Well, the k value formula for the injectors is easy, but I don't know the formula for the MAF. I don't have Nistune so I can't just let it do the calculation for me.

To swap the MAF, you change the VQ Table (easy), you change the K value (don't know the formula), and you change the TP scales, correct? From the quote from Nistune I posted earlier, they are saying to do the two formulas together for the most accuracy. I don't understand how they went from 34k to 21k. Anyone care to explain that?

Stock U13 K value is 33,107. So to modify that for Injector Dynamics 1000cc and N62 MAF, the formula would be:

33,107 x (370/1000) x (550/290) = 23,232

Does that seem about right? Then after that, all I have to do is change the injector latency, injector voltage, and VQ table, right?

Don't worry about it, he made a mistake. Let him know so he can update the doc. The 34,275 and 21,475 are radom numbers use as examples.

Confusing, thought you said you are using the Nistune software.

Really, I'm just trying to get a safe bin to start my car with the new setup. 1000cc injectors and z32 maf

You DO NOT use the burn feature when using a Calum RT with Nistune.

You simply enable emulator 1, which connects the RT with Nistune.

Use the Download/Upload to emulator option to read and write bins. Thats it

With the current BIN loaded and Emulator on, it will allow for real time tuning. With the car on, Emulator on and Consult connected you can do full datalogging and MAP tracing.

Awesome. SR20GTi-R, I think you have saved me a lot of headaches. I personally don't have the Nistune software, but I was using a friend's computer who has it.

To clarify, I do still need to download the drivers and hook up through the cable connected to the ECU?

you'll know it worked by shutting the car off and close nistune an re-start the car then re-open nistune and click the download image from ecu button it should be the one you uploaded.

if that doesn't work then i dont know.. i've never used nistune on a calum r/t.. you might try saving the .bin in nistune then uploading it with tunerpro or whatever program your suppose to use with the calum stuff, @Vadim would be the guy to ask about this.

No.

Upload image is ONLY a temporary upload of the BIN while the ECU is on. If you upload image and shut the car off, all changes after the last burn will be lost. The burn options writes to the board. This option is only for the Nistune RT. Does nothing for the Calum.

100% Correct. They both read bins/ADR's the same.

Smart move

I dont get what you mean by this.

Do it

Nooo NEMU or go home

[/QUOTE]

Unless you are revving/tuning past 8000RPM there is NO need.

PM me if you need any help. I am catching up to PM's tonight.
