Resized Injector calibration feedback

[hhorton]

I had my stock injectors resized to 36lbs@3BAR. I'll skip the long winded explanation of my tuning changes but ended up adjusting the IFR table by 121% to get to the final numbers I think are good. Check out the LONGFT graph and tell me what you think. Have I got it dialed in? This log was taken while I drove to work.. about 5 miles in town driving.

121%?
What size were the injectors originally?
How did you come up with this?

Did you use the spreadsheet (which uses the squareroot pressure equation)...?

Sorry, should have written 21% increase from stock. The stock injectors for a 2000 F-Body are 26lbs.

tried to but the figures came out much higher and i was running WAY lean so I just took the stock figures and started adjusting them by a flat % increase until I got what looked like a good LONGFT.

Below are the stock and final figures when you multiply the stock by 121%

That's a 21% increase
121% would be more than twice the original value.
1.21 = 21%
2.21 = 121%
121% would be too high of a increase.

Yes, multiplying a value by 121% is the same as multiplying by 1.21, hence a 21% increase.


But back to the original question. Is the LONGFT result looking good? Should I do more logging at higher speeds (highway)?
