Remote Start Timer

Hello All,

 

I'm hoping that this is the correct place for this, as I'd consider what I'm doing a "mod".

 

I have access to a Passthrough Pro 4 from Snap On. I'm interested in changing the remote start run time from the preset 10 minutes to 15. I'm not interested in just pressing the button again to get a total of 20 minutes by extending the preset 10 minute timer. 

 

I know that it can be done, as we have some wonderful people on here that would be happy to program the proper components and if I can't figure it out it might just come down to that. But being that I have access to the Passthrough which to my understanding lets you access factory programming as well as some custom programming I'd like to give it a shot myself first. 

 

I'm aware that I could totally screw up my truck, and well, I'm taking that risk.

 

If anyone has done this before or has experience I would appreciate some tips, or help. 

 

Thanks in advance!

I the passed there was ways to change things. Unfortunately it involves a device that was licensed only to dealers and even then a additional device that was heavily guarded was needed. 

The owner ship of said item can constitute a crime. I may or may not have owned one. To match vins on PCM so they could just be swap on the dyno. 

The newer stuff isn't any harder. I highly doubt the snap on will have the ability to change that. I know of software that can do it but it isn't publicly available. 

I will not high jack your tread any more. But to say you don't need more then 10 if you just want the truck warmer. 

Good luck and post your finds.

Nothing fun, is ever available publically. I just hate to pull the truck apart, send in the proper components to say, WAMS when at the moment that’s the only thing I’d wish to change. It’s also more of a just because and to learn how. 

 

Thanks for the input. Always appreciated.

      2001 silverado 1500 5.3L secondary air monitor won’t complete
      By 01Silverado2wd
      hello gm-trucks commuinty i’m having issues with a smog readiness monitor not completing. any information on this issue would be greatly appreciated. my truck is a 2001 Chevy Silverado LS 1500 with a 5.3L v8 and it’s 4x2. all the readiness monitors complete except the secondary air system causing the truck to fail smog in california. i’ve heard the air pump turn on at cold starts and even replaced the passenger side check valve. also replaced the solenoid that sends vacuum. everything in the secondary air system seems to be operating properly but the monitor won’t complete. i’ve driven 100s of miles and done countless cold starts but no luck. even the smog referee said the system is working properly and i should just drive the truck more. anyone else experience this issue and what did you have to do to complete the monitor? there are no codes stored currently and the truck runs fine. thank you to anyone that helps

      Driver's seat leaning to the left?
      By Jgardow92
      I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?

      L84 can I save it ?
      By Fredo1888
      My l84 5.3 cracked some pistons now thinking of doing a light hone but wanted to know if it would even save the engine ? The scratches are pretty light my nail doesn’t get stuck but I do feel em. The pours on the other hand I’m not sure what could have caused those little things ?

      2020 Silverado sway bar hitting CV axle
      By MisterEhEDC
      Hello all, My Sway bar was hitting my CV axle, as the title says. So I crawled under some trucks at the dealer to see what stock trucks are like and it turns out that the new TB/AT4's have longer end links then my 2020 TB. The new end link has a 3 inch rod vs the 1-3/4 inch OE part.
       
      The part number for the longer end link is P/N:85590925

      Need help diagnosing noises coming from my 2020 Silverado 1500 5.3L
      By Sir_Griglesworth
      Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle. 
       
      The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
       
      The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
       
      Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!
