Engine/Transmission (1998.5 - 2002) is there somthing wrong with my smarty?

[DMcPherson]

I have had a power issue, https://www.turbodieselregister.com/forums/showthread.php?t=173762

posted here.

I drove the truck today in a very hilly area. with the smarty on 9 or 8 I had no throttle under load, with my foot to the floor I couldent build speed, if I let up the truck takes off. if you get in the throttle a little and hold it it takes about 2 seconds then starts to pull if you floor it theres no power, let up and its back.

on the way home I set it on 3. no problems. the more you got on it the faster you went. let off and you slow down.

There are no codes. I thought vp problem, but the truck does not derate, just no power. I have 15 psi of inlet pressure at the vp at WOT

Just a couple ideas

1-aftercooler boot leaking you can loose some boost pressure there



2- in your prevoius thread you had a lot of transmission codes. It sounds like a dying lockup clutch or od clutch

 

[DMcPherson]

Im pretty sure the trans codes are from the lock up switch, the trans is a brand new mopar reman and new convertor. the egt's arent high enough to have a boost leak, and in lower gears it holds 25-30 psi.

Take your rig and smarty to the ct coffee night and let some else try your smarty?



A vp issue that has not yet registered?

Dan sent you a pm on this issue.

 

[DMcPherson]

Im thinking maybe a vp problem but no codes. it does run fine without the smarty, on not on catcher settings. wasnt there an update for no midrange throttle with the smarty?

 

[TClemens]

Dan the pedal travel is cut in half with the higher Smarty levels, my Catcher reflashed with #9 is the same way, you gotta find the sweet spot, usually half throttle, and you must roll into it not floor it, did you due the updates? if not they help a lil bit and make the truck easier and nicer to drive with less smoke.

 

[Bob Wagner]

is your smarty version 1. 06 or 1. 07?

 

[DMcPherson]

I think its 1. 06

 

[DMcPherson]

oh, and there is no real sweet spot. if you start to get in it you have to wait a second then it starts to pull then you can get in to it gradually, its reallly hard to hold or build speed on the highway.

 

[Bob Wagner]

then update to version 1. 07

 

[RCenters]

Mine done this I took out the smarty and it ran better but after a week or so it started doing it again and the VP died no codes and 20 psi pressure

 

[TClemens]

Dan you gotta update it, I did Tims and it worked out reall good pm me as I have the update all set to download to your smarty.

 

[DMcPherson]

I just updated, is version 1. 20b correct? it came from the site

 

[Bob Wagner]

correct

 

[DMcPherson]

the truck is way better, if you get in it fast it will do it a little, then go, but normal driving seems good.
