    Yup I was gonna suggest that next. Though the cost of Fusion or Parallels plus cost off XP/Win 7, might as well buy a cheap XP laptop and keep it in the car as a tuning laptop.

    Thanks for the response. I will probably end up running windows through boot camp so I don't have to borrow my bros laptop.

    I have a RTV2 for my B13. It currently has a V1 program on it and I am trying to load the V2 HEX file on it but it will not load. I believe that I need to "reset" the ecu per:

    "If you've uploaded a firmware that bricks your RT board…

    If you've managed yo brick your board (i.e. written some code that never responds to serial commands) you've got two options- either manually reset the board while the Colt loader is trying to connect, or use a hardware programming tool like the ICD2.

    To manually reset the board first remove the cover. Next, find JX as show below."


    Can anyone tell me how I got about "resetting" my ecu so I can load the HEX file into it?
    Thanks.

    Thanks for the reply. I had emailed Dave. I have a local guy who has an ICD2 at work that was able to erase the ecu and load the hex file. Looks like I'm in business.

    Awesome, you should consider getting tunercode for it (if obd1). You wont regret the new tuning features.

    I was not able to get the ICD2 to do anything, but on the programming port there is a CLR pin for the memory chip. I was able to start the bootloader then ground the CLR pin and it loaded in the HEX file. For anyone who needs this, it is the 6 pin connector that is parallel with the PCB on the underside. The pins are labeled on the top side, 1 - 6, pin 1 is the CLR and pin 3 is ground. Using a piece of wire connect the 2 pins and the bootloader will initiate the programming.

    I have tunercode that he could use, not too familiar with this stuff yet but i hope to learn as i go.

    Sorry for the n00bness, but I'm looking for engine management/tuning for GTi-R engine into a 2002 G20 5mt. Do I have any options for hardware/software? Don't worry, someone WAY smarter than me is very capable of installing and tuning it.

    Front page shows all of your tuning options. Use a Sentra or P10 ecu and chip it.

    Thanks! One more thing...would a B14-to-P10 adapter harness help me in that case? (Apexi Neo AFC)
    Sorry, this is way over my head but hopefully since I'll be doing part of the work during the swap I'll gain a better understanding and be able to help other in the future as you do.

    (I'm KH3 P11 also by the way, our cars look a lot alike.)

    @Vadim, can you also please post/update 'old' k-values for Z32 MAF? By using your formula and the k-value of 399 on most of the 370@ 4 bar (427cc) tunes I could find, it appears stock k-value on z32 maf is 657(399/(259/427)). I've found, however, that this kind of conflicts with other k values on other tunes. In other words, what the k-value 'should' be based on this formula, it isn't or it's pretty far from it in some cases (one I saw off by 40).

    There is no such thing as stock K value for Z32 maf for our cars. There is a K value for 300zx, but since it's a different engine with different injectors that number is irrelevant. Your best bet would be to find a 259cc z32 maf tune (good luck!)

    I'm just saying your numbers of 298 are for 259cc injectors and stock MAF. I believe 259cc injectors with Z32 MAF k-value would be 657 based off your formula and reversing it for what I believe is the most popular tune (370@4 bar, z32 maf). Because we can't use your 298 figure if we have a Z32 MAF.

    Just as an example..

    259cc z32 maf = 657
    upgrade to 370@4 bar(427cc)

    (259/427) * 657 = 399 k-value (What I saw on all the tunes)

    Another example with 740cc injectors..

    (259/740) * 657 = 230 k-value

    The 657 value seems to get within 10-20 for most of the other tunes I saw with upgraded injectors on a z32 maf tune when I used the formula, so it's probably a solid figure to use.

    You got it, I personally don't spend too much time calculating the K value, since I can edit it while I drive and see AFR's in real time. Now also that's not my formula, that's the one I found on lots of forum posts.

    Now the reason I said there is no such thing, no one really runs a 500whp maf on stock 259cc injectors .

    Also as a rule of thumb, when you upgrade MAF you have to increase K value to give more fuel. I think this is because higher HP MAF's stay in the lower volts a lot more thus the VQ number is going to be smaller, thus you have to compensate with higher K value.

    When you upgrade injectors you decrease the K value, bigger CC injectors are able to flow more fuel at the same amount of time/pulsewidths, thus you need to reduce the overall fueling by adjusting the K value.

    I think that's exactly right. I think it has to do with calculating the TP value which includes VQ number in the calculation. 4v on a b14/b13 maf flows a lot less air than a z32 maf @ 4v.

    TP= ((VQ*K/(RPM*256/50))/Cylinders

    ^ Using the above value, you could theoretically calculate TP value as long as you're logging MAF voltage(covert using VQ table formula) and RPM. Just make a formula conversion in excel.

    As an example with 740cc injectors with k-value of 230, RPM of 5000rpm, and maf voltage @ 4.00:

    TP = ((29324*230)/(5000*256/50))/4= 65.86

    Could be a poor man's map trace

    ^^ Man I don't miss tuning my Calum ECU because of these manual calculations. Nistune handles this so much better, and that will be because of the tuning software. The only time Calum ECU is as good as Nistune in logging department is with TunerCode (which is no longer sold as stand alone firmware). Calum ECU with TunerCode trumps Nistune in the tuning department, but not as good as NEMU RT. NEMU RT beats everything in tuning and in logging department.

    Calum's values for the TP and RPM scales on the b14 are correct, but reversed in his post. In other words, where you see 'TP' put RPM and visa-versa.

    @Vadim: Can you please fix this?

    Wrong:

    B14 SE-R 95-97 (G20 94-97) Map Trace Values:

    RPM MSB - 3472
    RPM LSB - 3471
    TP - 314E

    Timing map - ED00
    RPM Scale (timing) - E480
    TP Scale (timing) - E490

    Fuel map - E100
    RPM Scale (fuel) - E0E0
    TP Scale (fuel) - E0F0


    Right:

    B14 SE-R 95-97 (G20 94-97) Map Trace Values:

    RPM MSB - 3472
    RPM LSB - 3471
    TP - 314E

    Timing map - ED00
    RPM Scale (timing) - E490
    TP Scale (timing) - E480

    Fuel map - E100
    RPM Scale (fuel) - E0F0
    TP Scale (fuel) - E0E0

    Well I thought of that but there are at least three different options. Nissan datascan I , nissan data scan dash I dash , and nissan datascan II. I downloaded your beta XDF from the first page thinking that's all I needed but after reading datascan website I am unsure that it will work with tunnerproRT And the beta XDF. I don't have a consult cable just the USB cable from the Calum rt ecu.

    Nissan Data Scan and TunerProRT are two different products and don't interlace at all. Nissan Data Scan is for logging only through consult port (which your Calum ECU is able to emulate through the USB cable). TunerProRT is for modifying the bins's only (as it is today, if someone makes an ADX file it could technically be used for logging too). That XDF is a definition file for TunerPro, it tells TunerPro what parts of the BIN to modify.

    Sorry I'm new to this but working on it. I am trying to Log my TP. I was reading on the first page and thought your Beta B14 XDF file was properly modified to use NDS and log TP. I guess the real question is which of the three latest offerings of NDS will work the same as the old NDS 1.4 did. I was thinking of buying the NDS Dash since its the cheapest and for what I'm going to use it would serve my purpose, or at least that the plan.

    NDS I 1.63 should work fine, Dash and NDS 2 might work, but I haven't personally used them.

    Reason you need to use TunerPro and the XDF, you actually have to make changes to the tune and upload it to the ECU, then can NDS pick those changes up (after configuration).

    Posting this up for anyone in the same situation. NDS's latest version works just fine with the XDF, and it is some what free. I have successfully downloaded it and got it to work. Also I'm using windows 8! and it seems to work fine no issues. Thanks for the help @Vadim

    I'm thinking about getting an MR2 Spyder and we should be *very* lucky to have such awesome AND cheap tuning options. On the MR2, they have to use a standalone ECU like Apexi PowerFC or some other $1k tuning option which isn't nearly as compatible and customizable as what we have.

    This is part of the reason why I went with a Legacy GT over Altima SE-R, being able to tune just about any turbo Subaru with a $200 cable is awesome, but the community is huge, thus lots of people to make good ECU definitions. I'm surprised MR2 would be so lacking, seems like a fairly popular car too.
