help with fuel and $8D XDF

'edit parameter xdf info' or method two 1. highlight the parameter in the list 2. smack 'F2' from there go to the DA ASSOC tab and create explicit links to your ADX as per my earlier post good idea, i'm sure those guys can get a data sheet for you. the offsets would be nice to get correct before you tune as it'll throw stuff off a bit. you'll likely find that the columns don't match up, the data sheet might be for 10.5v, 10.8v, 11v, 11.8v but your ecm might be 10v, 11v, 12v or something. here's a cubic spline tool that'll help you transpose the offset table values in the data sheet to match the ECM's rows: http://www.akiti.ca/CubicSpline.html

lol, if it wasn't for the community effort this car would probably have a carburetor on it right now. FIC sent me the data Did I us this cubic spline tool correctly? Here's what I got. In the known data box is injector offset at XX.X battery voltage. in the X boxes on the left under Points at which Interpolant Sought is the voltage tunerpro wants and the right Y boxes are the calculated results for my new injector offsets at those voltages.

no, you didn't use it correctly (it's backwards)

your input needs to be:
voltage ms
voltage ms
voltage ms
(with voltage increasing)

your output needs to be
voltage
voltage
voltage
(with voltage increasing)

Those results look very different from what is in my factory tune.

I'm trying to get cell tracing to work. In XDF head editor under DA Assoc. I clicked browse to associate with the ADX I am using but does not show it as an option even if I click 'all files'. So I went the normal route to see if it was still there, I went to START, DOCUMENTS and my ADX is there. Why is this happening?

that picture you posted are the stock values, right?

no idea? it works for me? afaik you don't even need to do that for data tracing to work properly; when i was playing with it, i never had anything in that field.

I still can't get cell trace to work. I matched X and Y and adjusted settings for Engine Speed, RPMs, MAP and Kilopascal, then toggle Data Tracing. I matched XDF info to ADX also. Still does not work.

Cell trace still not working... Got my ALDU1 datalogger from moates I setup the com ports and tested it in tunerpro with success but it doesn't work. No information coming onto the TunerproRT dash and it still says DA not connected. I highlighted everything from 60kpa and under and removed -40 from the VE table and it did nothing to lean out the rich idle and light throttle cruise. I played with Startup Enrichment vs Temp and it did nothing. It does not specify coolant temp or air temp so who knows what that means? I also tried adjusting Open Loop % Change vs Temp but it also did nothing and does not specify where it gets temp from.
