Data Logger Worth it or Not?

[AveryMcLawhorn]

So question for everyone that got a data logger. How much ET did you pick up from the data logger alone from identify the optimal configuration?

Mine is in a bracket look alike super stocker. It should me converter to tight. Motor going rich on top end. Played around and gained a solid .12

How about we ask a different question. How many feel that the data supplied from runs and about changes saved you both a nice amount of both time and money?

i have a racepak sportsman with a o2 you don"t know what your missing without one great tool wouldn't be without one

The rpm DL10 seems to be the most cost effective for those on a budget. Can the 2 o2 package be added to the DL10?

This is our 1st racing season with one. (Racepak Sportsman) Here are the ways it helped us, above better dial-ins. So far it has helped us to fine tune the A/F since we have the 02 sensors in the collectors. Shift points, launch rpm's and tire pressure based on driveshaft rpm vs engine rpm and the acceleration G's. It helped us diagnose a voltage drop on the run when we were .05 slow to our dial. Tracked it to a loose alternator plug. Then further dug in and found a voltage sucking on-off master switch. Yesterday we went out to do some bracket racing. Car was just as fast as it should be in the air on the 1st pass and we thought we had zero issues. On the run the data showed we dropped from ~45psi Oil pressure on our SBC to ~7psi. Packed up and headed home after watching our friend go a few rounds. Don't know the damage yet, but ZERO indications otherwise we had an issue. We are saving $$ and possible my hide with that data logger. If we made another time trial and the motor let go and shot oil everywhere who knows what happens. Never thought a data logger was a safety purchase too, but it could be. I wouldn't race without one. That is just me. I tent camp when I race multiple days and shower with a modified weed sprayer. I am not a baller. The $2500 we have in our data logger was NOT an insignificant purchase to us.

Happened to me last year. Saw really low oil pressure, put it in the box and went home. Pulled the engine apart and blackened the crank, had some not great looking bearings but saved the engine. New crank, oil pump and bearings and back to racing. Just a bracket engine but the only one I had at the moment.

It inputs just like any other sensor though the WegoIII board.

Thanks. I already have the wego 4 and it can also log onto the DL10.
