Weber selection and initial jet tuning

Ok, electrical issue sorted (bad alternator) and back at it. 

Did a log tonight here...hot and humid out......165/230

155/225 still seems best...might start there again and then start testing the e tubes.

Glad you are sorted. Yes that run looks nice but as you say 0.5 point leaner will be nicer.

I did a comparison and the newest data (green)  now looks normal across the rpm range.  The160/230 (pink) run seems anomalous with the big hump in the middle and may not be valid.

The data also shows that the 225 and 230 air correctors are too close to make a difference.  I am now thinking the drilled 238 may be flowing more than a "manufactured 238".  So a 235 or 240 air corrector may flatten the curve.

 

 

 

 

Removing the pink data gives:

Could you please try the 160/230 again to rule out the anomalous data?

[blodi]

Will do. I'll pop it back in tonight.

Ok......160/230 again....much more inline with what we would expect....maybe overlay this with the 155/225 and see which we think is the better baseline to begin e-tube testing......

The data seems to scale correctly now but the air is not doing enough to raise the top end and flatten the curve.  I think a manufactured 240 air with 165 fuel is needed.

The 160/230 is the best combo so far.

Please keep the 160/230 and give the new E-tubes a spin!   (Let the fun begin! )

F11's are in! Took a log this morning on the way into work. I'll get another one on the way home and upload tonight. But on watching the gauge it seems much richer throughout...though maybe flatter?

 

F16 vs F11....

F11's with the 160/230 combo

Also, I went ahead and installed the F2's tonight. So, I'll have that data tomorrow.

F2's look mighty rich during the pull I did this morning. Logs tonight.

F11 is slightly flatter but richer overall. F2 will be interesting. I am traveling and will post plots Friday evening.  Great work to collect so fast. I am impressed.
