    I'll have a crack too...

    Find deadtime at 12V (since you're only interested in low slope)

    Then run it at a range of low pulse widths. e.g 0.8ms, 1ms, 1.2ms.... etc. for a decent amount of time, tracking PW count and fuel mass.

    Commanded PW - Dead Time = Injected fuel PW

    For each Commanded PW => Fuel g/s = Mass of Fuel in Container / (Injected Fuel PW * Count)

    Plot the points in excel and draw a best fit straight line. Where the points 'knee' into the linear range is the break point. Stick your high slope onto your lot at that point. Bada bing 

     

     

    Yeah okay i might have a play when i've got some free time and sit down with it n plot them all.

     

    Im running metholated spirits in it at the moment, it was cheap and best thing at bunnings 😅 only thing that was open by time i got to post office to pick it up.

  2. Cheers yeah il have a read through them, i didnt buy it to collect the data just thought might be handy to try it out if it can do it. I do have a cheap handheld ebay scope somewhere i bought for tuning amplifiers years ago when i was really into car audio so might try the scope too

  3. So i've just purchased a injector tester and cleaner, i did a static test with and fg n/a injector and came very close to a high flow rate of a fg data, i was wondering if anyone knew how i could test for the low rate slope?

    This is from a NON ABS ute but shows VSS source as ABS. This is where your comparing files in HP is going wrong.
    You won't see the actual speed source currently being used when you look at the strategy using HP. It's not defined or displayed.

    If you don't know the workaround, you're wasting your time using HP. The info is out there but it's not really something that belongs in this forum.

    Thats how the file looks in the manual car

  5. Yeah they are both customer supplied ecu's.   The auto came in for a ecu link and tune and they were told there ecu was the issue not the tune, but compared to the stock ecu the speed input was the same but i fixed that.

     

    The manual customer has been told i need to work out there issue first before buying the credits. I only have pro version so unable to read there file in pcmtec without unlocking it first with the 2 credits hence why i used hp to read it and it was a mail order tune with PATS disasbled ( should of mentioned that) but it has a manual OS on it i forgot the calibration code atm. But the VSS input is set to ABS currently

  6. Had this issue twice now with 2 diffrent cars. 1 auto 1 manual

     

    The auto had a faulty ecu so i'd replaced it and it had no speedo after replacement ecu with P0500 

     

    I did use hp tuners on this car as they requested i use it. But it only worked after a 2nd ecu and i wrote a diffrent O.S onto it.

     

    So with the manual car its had a new ecu as original has been lost it also has p0500 read it in hp tuners just to look at it and compared to another manual it all looked fine. So without any abs errors does anyone know other causes for p0500

    stupid question, say if first gear is 2.743 to one, how do i calculate it out? 

    is it 2.743 times xRPM ?

     

    So i did some research and found someone from HPtuners and found the user hiddeous had compiled a excel sheet for the ZF transmissions, i have edited it to suit the BTR gearboxes, Full credit goes to Hiddeous for making the file.

    instructions are to fill in the yellow sections with the desired data, i suggest filling out desired shift speeds in KM/H then look at the engine RPM its shifting at then lower it to suit so your not redlining it then copy the final OSS table

    Sorry if this isnt aloud admin, i was hoping it would be able to help others out
