Lock Out/Lock-Up Tuning

[phunt]

Ok, let's talk about the first .4 seconds of the run (look at bottom of the screen) this is where the spring pressure(base pressure, installed height) is working with the lockup, but if ya look at .2 seconds that's all spring pressure. These passes are blue-24lbs pressure black-23lbs pressure red-22lbs pressure. So until you take a spring pressure gauge and measure your pressure your blowing in the wind with just guessing spring pressure. Any ?s feel free to ask

.2 dip is slippage before the lockup starts to work? Is the chart in clutch or engine rpm?

[Surfrjag]

If your lower your spring/base by a lb are you adding any arm weight?

Will that graph show Iif it never fully locks up? Does it?

this is clutch speed

change only one at a time, you can change spring pressure and arm weight but which one did what?

Did the blue produce the best 60ft time?

the lift is the fight between the springs slipping and the lockup trying to lock it up

[phunt]

Did the blue produce the best 60ft time?

yes, it had a faster acceleration

[#1JUANstunna]

yes, it had a faster acceleration

Ok, I thought that's what the chart was showing just making sure I understood it.

The lockup on dirt is lockup in the first 5ft-10ft

This has me thinking. My current set up has too much slip off the line. It's slipping about 15ft out and then locking up. I need to get a better assortment of springs.

if it slips to much the lockup is not going to lock it up

[#1JUANstunna]

I believe that to be my problem.

What data logger is that chart from? Does it read off a simple sensor on the clutch side and output side of things?
