Best sensor which does exactly what its supposed to do.

Edit - looks like Jeff was right as results from my testing, show that, "Going by Aquamist convention, yes, full CCW (counter clockwise) would be the 2.5v minimum." You just turn that screw counter clock wise to the first tick mark , and that will be 2.5v. then screw the cover plate back on, no need for resistors.

I'm guessing on the way the marks represent voltage. Jeff sold them so fast he did not get to try it. I hope to have it tested out this weekend.

Got overflow code where I thought was 2.5v. Moved to what Jeff thought would be right (turn adjustment screw all the way counter-clockwise), got overflow again.
Just had a couple minutes last night, will log tomorrow. Could be the labonte unit was leaking for longer than I knew so me meth flow and setting in procede were too low for a while. Will update tomorrow. Anyone know what an approximate flow setting (injection mode value) would be for a DO14 nozzle? I'm guessing 16 is way low. Last edited by scottp999; 09-21-2012 at 07:34 AM.. |

Got a little time this morning. Learned that with the scale output screw turned all the way counter clockwise, that a DO14 nozzle will hit between 38 and 40 (small spikes to 42) for meth flow in the procede log.
That explains the overflow codes when I had the Injection Mode at 16 since 40 >= double that value. I found that with a setting of 26 the car did well. After I shut the netbook down, on the way home, I floored it in 3rd from about 2500 rpm and somehow tripped the overflow at the onset, so I must have somehow caused a spike to 50+ on the flow reading. ** Edit, just saw enrita's post saying overflow is auto at 90 (either double injection mode value or 90), so I might keep the DO14 in there, bump injection mode up to 30 and see if I can avoid overflow conditions in all circumstances and still skip the resistors.

I would change the procede flow value to 33 and then try. If it still triggers an overflow situation, then I would set it on full volts and do the resistors method and call it a day. Don't matter what size nozzle as I am using a M10 and M7 and it doesn't cause a overflow on Procede.

Pretty repeatable results on the flow reading, looks very predictable. This was a slow shift from 2nd to 3rd. Each data log the flow reading looked to have the same curve and values under full throttle.

Its working perfectly with a meth Injection Mode setting of 30 with the DO14 nozzle (with the scale output signal span screw turned all the way counter clockwise). Logs show flow reading consistently hits between 38 and 42 at WOT.
Now all Howerton needs is to get more in stock. |

One interesting note, I put in a DO 12 and it flowed steadily at 43. Maybe I had a narrow DO14 and a wide D012, not sure. Last edited by scottp999; 09-23-2012 at 06:16 PM.. |

Great to hear...Not only is it easy to hook up now with the one you have, the best thing is the size of the sensor which You can install almost any where in the engine bay and its works and keep working. Heat doesnt seem to play a factor on this flow sensor, and neither does the meth volume.
