Thread: HyperSpark install dies idling.

    Ideally it'd be best to have your current Config File and a datalog of idle and some light driving, about 50 to 10 minutes worth. For now, however, the Config File would be sufficient.

    OK, quite the ordeal with an outdated laptop, but I think I got it. New Base Timing Table under FW0101/SavedGCF/Mustang_1.sniper. A few things to note, the closest table I could find under TerminatorX per Chris's instructions @ EFIsystemPro is:
    BaseCal/Ford/Smallblock/TFI_NA_FBF_MPFI.terx
    Two were supercharged, two were turbo and one other had transmission control. I think it's setup for a 351. (I'm running a 302 with mild cam.) The real change is the base idle timing went from original Sniper setting of 15° to 12°.

    I compressed the complete SD card for anyone to look at to see if they see any anomalies, screw ups or the like. If anyone could direct me to the files I should be looking at to see what you guys look at, that would be great as well. Thanks everyone! ROG HOLLEY.zip

    First, you should've downloaded the GCF in the Sniper currently and made changes there. The Mustang saved GCF will get you into trouble. You can save yourself, but don't load it into the Sniper as is. Load it back into the EFI software. First, go to the SYSTEM ICF and under the engine you need to set this to 302. Using the 350 that's in there will confuse the Sniper and at any given RPM will cause it to dump a lot of fuel. Next, you need to change the ignition type to HyperSpark. It's currently using coil -. As discussed, you can use the defaults of 57.5° and 100 for the Inductive Delay, but these need to be confirmed as discussed. Your SPARK Table is very conservative. I would feel comfortable raising it by 3° to 4° across the entire table. Not so easy to do in the EFI software, but easy to do in a spreadsheet. Copy the contents of the table into Excel, add 3° to each cell, and copy/paste back into the EFI software.

    The Target AFR values are pretty rich. Change them to 14, 14.5, and 12.9 first and then set it to 2D Table. However, do this after you reset the Base Fuel Table RPM axis to 6250 RPM. It's currently set to 8000. Then go to your Base Timing Table and use the COPY FUEL AXES function. Type in 6250 for the max RPM in the Base Fuel Table and press enter to save that value. Then, right click on the 6250 and select FILL ROW VALUES and this will evenly space the RPM axis values.

    In the future, any time you want to make changes to your tune, download the tune from the Sniper to the SD card using the SAVE AS function in the handheld. Transfer the card to the computer. Load the tune, make your changes and then use the SAVE AS function to save the changes you made. This way you have your old tune in case you made a mistake. For example, you could Save As and put 6 27 Mustang Time Table so that you know what you did and when you did it. Always leave yourself a backup. In fact, if you make the above changes and save it to the SD card, before you upload this new tune make sure you download the current GCF first so you have your backup.

    Why I suggest adding 3° to the table is that combined with the rich AFR values the engine will probably feel a bit lazy. Or correct the basic setup such as displacement, AFR, and ignition and save it. Take that tune and add 3° across the board and save that as "plus 3". Load the first and drive it. Load the second and drive it and pick the one that runs the best. That SD card is huge and will hold a lot of Config Files.

    Hope this makes sense. There's a lot to learn and I feel comfortable that I have a good 20-30% of it. If you post another Config File after making the above changes I'll be happy to check it out.

    @GPatrick: OK, thanks for clarifying as I couldn't for the life of me figure out why the dates on the files were so old.

    I put SD card back in and downloaded file from ECU and named it Mustang_0 in save as mode. It still has same timestamp, did I do something wrong?

    The Sniper system does not have an internal clock/battery therefore it won't save date/times as in internal function. Every file it saves will have the same default date & time. You can resave them as any name/date you want.

    In the instructions and in practice, manipulating the cells in most tables is very easy when you understand the hot keys and available functions. In this case, if you were going to do exactly as you described within the Holley EFI software, you'd left click, drag, to highlight the entire table. Right click and use the Offset All function. You then have the option to offset up, down, and even by percentages.

    OK, I changed the spark table adding 3° across the board. I also brought down the RPM to 6250 from 7000. I changed the CID to 302. I changed IGN to HyperSpark.

    GPatrick & I mentioned this several times in this thread.

The Target Air/Fuel Ratio Table & Base Timing Table can then be properly configured & tuned for any engine. I always suggest taking notes of your current distributor's ignition timing specs/curves beforehand, and then program the Base Timing Table accordingly.

    @ Danny Cabral: OK, thanks. Good to know.

    @a b c: Thanks! That'll save me the countless hours I wasted already trying to do it in Excel (which I know nothing about) if I'm understanding you correctly.

    @GPatrick: New (hopefully) corrected file uploaded. MUSTANG_2.sniper.zip

    A few things. In the distributor setup you need to change the Reference Angle to 57.5° and the Inductive Delay to 100 usec, which are the default values. In the Target AFR, plot the graph and you'll see that it's very jagged. From the graph, hit the Smooth All button 3 or 4 times to smooth out the transitions. In the future, you'll be making changes in certain regions, but this will improve your driving experience for new. Of the two, you need to correct the ignition first.
