Since Jason has not posted it, mail me directly at cewrx7r1@yahoo.com. I'll then send it to you. It is in MS Excel format.

 

Here is the link to the file Chuck is talking about.

I missed 4400 thru 5200 for N18 thru N20. These are too high.
Should be brought down.

 

is 19-6000 in IGL right? 12 split but just looks strange.

what should the corrected be for 18-20 4400 to 5200 be?

14-5200 at 22?

Jason, row heading 31 in the analysis, which would you change and to what numbers? you mentioned 2 in IGL and the rest in IGT, which ones?

Thanks guys.

 

For 19-6000; I did not want to go into other types of analysis, but you noticed it. Even though timing advances with rpms and retards with boost, there are some places where these trends are not exactly followed. 6000 rpm is about the area of max torque which means the engine is consuming the largest amount of air and fuel per intake charge. This is the most critical time for
preventing detonation. That is why you will see the timing retard a little around this area at the higher boost settings.

The other odd area is idle and just off idle conditions.

For the 18-20 4400 to 5200 region, the split is way too high. I would work on both the IGL and IGT to get them down to 14 to 15 range. for 18-20(4400) I would retard IGL to 11, 10, 9. Then adjust IGT for the 14 to 15 split.

(14-5200 at 22?) correct, you got it!

The idea is to keep the correct timing for safety but to also keep
it smooth and consistant. Remember that when the rpm and boost parameters are not exactly equal to a cell, the computer extrapolates from the closest cells to calculate the timing and fuel.
Data that is out of the norm will cause faulty calculations.

 

I hate being away from my computer . . . not only do I miss out on the forum, but when I get to check it, I can't view the new spreadsheet!!! Anyway, did anyone fix the error in the IGL map yet? That number should be 22 not 2.

 

cewrx7r1,

Cool. thanks man, I appreciate it.

by the way, would anyone happen to have a spreadsheet for the stock maps, just for comparison?

 

Interesting . . . now that I have seen it I'll have to look at it closely.
