Dan was nice enough to run his laptop on my truck and do some data logging. Seems I make more rail pressure when I am not WFO than when I am around 30-50 percent throttle.

Here is a bit of the logging.

It goes time, rp, % of throttle.

Yikes, I'm not too good with all that......

 

Shouldn't pressur ebe a bit lower than as the fuel should be dumping into the motor??
I too am not sure about alll that number stuff.

 

Basicly what I am seeing is the truck (due to the Smarty) is ramping the FP to WFO even though the throttle is only at about 30-40 %. So on this line...

08:29:27.015, 20732.10, 08:29:27.156, 47,

The truck is making max pressure @ only 47% throttle. The problem is the transmission isnt seeing the throttle required to shift as it should.

On these lines you see MAX psi achieved at less than 50% throttle.

08:29:30.609, 23540.75, 08:29:30.781, 42,

So, I know I need a bigger pump (cp3) and that should get me to 27,000 like everyone says I shouls see. But not before the tranny rebuild. She is in bad shape...lots of slippage and tons of HEAT!!!!


End of the story is....Thanks Dan for your help, and we will talk about the Dodge upgrade soon for your logger!!!!

 

How many miles do you have on the trans??

 

No worries!! I have some ideas Id like to look into first!!

 

I have 83000 hard miles...a lot of towing, racing and just rough driving....Thanks to phil she is still running strong....but due for some work...

 

Got it!
I'm trying to save my nickles and dimes for a trans....
