    Stock Spark Map Downloaded (Final Version, pg1)

    [size=99px]***Revision 3 (final)***[/size]
    This is the final version of the map, with the correction tables, downloaded straight from the OBDI ECU (by emailer33).

    Download Excel file here:

    Latest datalog from an OBDII saturn:

    Thanks to Special Forces for the logs.
    These are the ACTUAL values, once the correction tables are taken into account, of an OBDII car.
    Fully warmed up on a reasonably warm day.

    I'm not sure what the difference is between OBDI and OBDII, presumably very little, so everyone with an LLO should be able to use these.

    MAKE SURE TO CHECK THE TIMING WITH A TIMING LIGHT TO MAKE SURE THE VALUES IN THE MS CORRESPOND TO THE ACTUAL SPARK ADVANCE.


    OLD MAP AND INFO BELOW
    ================================================== =====================
    [size=99px]***Revision 2***[/size]
    This is the latest stock spark map.

    Download .VEX file here:

    IMPORTANT!!! Before driving around and tuning your car with ANY spark map, make sure to check with a timing light that the numbers on your laptop correspond to the actual timing advance, and adjust the setting appropriately. For example, on my car I had a 10* difference between the MS dash and the actual advance, so at 23* advance (MS) I was getting 33* advance (actual). So check your settings.

    MS2 users should be able to configure trigger offset, it is one of the features.

    Latest log info below:

    Log1 Average:


    Log2 Average (From previous logs):


    Log4 Average:


    Log5 Average:


    Mainly the highway driving/cruising section is refined. Some higher RPM values adjusted. Idle angles adjusted.
    100 kPa range adjusted up from stock to even things out (and increase power).

    =========================== Revision 1: ===========================


    So some of you may remember the thread I made back in the day in the "For Sale" section about giving away a free OBDII scantool to someone who has the equipment, a working car that isn't heavily modded and some time. So I sent it to Joe (Special Forces) and a few days ago I started receiving first datalogs from him. The idea here was to drive the car through a variety of load conditions and RPM points to fill up a high-resolution spark map, effectively downloading the stock tune.

    The goal of this project is to provide everyone with a true stock spark map to use as their base map with MS and other standalones. Based on the information I received, here is some data and the first tentative map is on the bottom of this page.

    Log 1 - Hi-Resolution, appears to be during warmup (close to full operating temp):


    Log 2 - Hi-Resolution, full operating temp:


    Log 2 - Hi-Resolution - Maximum Values
    (some values have small "hit" ratings, so they might look out of place)


    Log 2 - Hi-Resolution - Variance
    (This is the average variance between recorded values. Higher hit values will have a smaller variance, while rare hit ones will most likely appear high on here)


    Log 1 - Lo-Resolution


    Log 1 - Lo-Resolution - Maximum Values


    Log 2 - Lo-Resolution


    Tentative Map

    The values here had to be interpolated some, due to the short duration of the datalogs and low hit ratings on some of the cells. Overall though, this should be pretty damn accurate and should work fine as a base map. The more data Joe sends me, the more accurate this will become. I will keep updating this thread until we have a solid map.


    Map can be downloaded in the form of a zipped .vex file, attached in this post.

    I'll be working on getting more logs in soon. This way everyone can get a more precise map and tuning won't be as much of a guessing game.

    It's a 00 SL2 with SAFC and bolt-ons. SAFC shouldn't affect things much at all.

    Re: Stock Spark Map Downloaded

    the safc could have a big impact on time i would think. tricking the pcm would have to skew the output wouldnt it? i would think it would depend on how much he has changed settings in the safc. but none the less this is the best things we got to go on. thanks for the map it will help out a ton.

    Re: Stock Spark Map Downloaded

    Not really, his MAP just doesn't read above 90 kPa because of SAFC, just scale it and pretend that 90 is 100, the spark map is really still the same.

    Re: Stock Spark Map Downloaded

    I don't have a SAFC. [img]{SMILIES_PATH}/confused.gif[/img]

    I'm as close to stock as you can get tuning wise. I don't have much in the way of bolts on except a CAI and lightweight flywheel really.

    You guys are getting readings stock for stock.

    i have a stock 97 sc1. after special forces is done you could send me the tool and i will donate maps for a single cam. i know their is a few single cam racers out their.

    Well it's his tool now, so you're gonna have to ask him. I don't claim any rights to it [img]{SMILIES_PATH}/biggrin.gif[/img]

    Don't bother.

    I've been running with it for the past couple days and I gotta say the car feels way nicer. Even the mileage improved. The spool improved dramatically for some reason. It's rather sweet.

    Awesome. I'll be going out again this week when I have a break in school, studying, and other committments. Can't imagine what the map will do when I get fuller logs.

    Re: Stock Spark Map Downloaded

    Yeah, it'll be very interesting. Next step will be to use a timing light to confirm that the values in MS correspond with real advance. I suspect MS might be a bit off. Once we verify that, we'll have a lot more to work with [img]{SMILIES_PATH}/biggrin.gif[/img]

    Looks like the Saturn engineers are better at tuning spark than you!

    No shit. I was happy with 20 mpg and shitty spool until I saw the light.
