Default Re: 8100 Tuner

Good evening. Adger, I'm curious about your results with this, assuming you got yours programmed. I have a 98 3500HD, 454 with older whipplecharger. Swapping the computer out and the shop working on it says it's running like crap. They feel it's due to the stock tune not working with the supercharger. I'm looking for someone that can help my guys get this thing under control.

After I bought my low mileage 2002 8100 WD 3500 I had some serious health issues and have just been using it between the house and farm. (no racing.. 44' LQGN sitting.. Just toating the Kubota) Soon after I got it in 2016 I noticed some issues with it missing and sometimes it died. I changed to the updated Crank position sensor and all problems went away. I have made a couple long trips in it. The longest from NE Texas/SW Arkansas to Minnesota. April of 2023 I delivered an engine to Ringgold Ga. while I was there I stopped at RED and Ronnie loaded down my 30 ft goosneck with 36 SBC engine blocks and several BBC blocks. It did well going back to Texarkana. Loaded and at Interstate speeds it averaged 9.75 MPG on the way home. I had a tune that ED Wright had sent to me, but had a comuter crash and lost it.. that was just after we had lost Ed. This truck really has served me well. It is nearing 58,000 miles on it. I still plan on doing some mods to it, but I just haven't taken the time.
Alan, I was wondering if you still had that 8100 engine and Trans I delivered to you. If anyone has an update on the tuning of the 8100 let's keep this thread going?

I looked online into the Black Bear that Alan mentioned earlier in this thread. I've also been questioning others recently on this as well, and I've been hearing about 0411 PCM swap. Seems more folks prefer the 0411 to Black Bear. According to folks I spoke with today, it's more user/tuner friendly. I was advised to get a base tune, then get to a chassis dyno for a more specific tune. I'm pretty computer illiterate with these things, so having to rely on others for this project. Really hoping this gets the truck squared away.

I have learned that the limiting was done to also extend the life of the transmission.

I own a 2002 Silverado LS Dually, 2WD. I purchased the Moroso wires and used NGK plugs and also use the Wix 51515XP oil filter since it is a 2WD. Switched to Mobil 1 Truck & SUV Synthetic oil and the oil consumption also dropped. With the larger oil filter, you have to add an additional quart of oil. If you truck is a 4x4, you cannot use the larger oil filter.
Try the Delvac Mobile 1 Allison fluid, it sheds heat better than any fluid we?ve seen.
If you can get an Allison trans I?d do that. If a fireman can?t break them they are bullet proof!

Barry,
Mine has the Allison 1000 series With my load and the "Tow" button on the shifter activated I have never seen the Trans temp gauge go high, even with the load of engine blocks. I'm assuming the trans temp should stay under the engine water temp. Water temp is never over 210. I really like the Transmission braking feature of the Allison. I think the up shift points are a little high, even when not in tow mode. I've been thinking about doing a Transmission & rearend service this winter. I have read up on the transmission and seems like they use a special fluid. I've been using AMSOil in my other trucks and was considering making a change. The truck had a Quaker State
Sticker on it with mileage for changes. I have used Q-state on all my changes. There is a little more oil consumption than I like...Thinking about making a change and see what happens.

Adger,
I had mine serviced and flushed recently and switched to the Transynd 668 fluid.
The shifting improved dramatically with smooth and firm shifts.

I used Rocket Chip on my 8.1L motorhome. Saw improved torque and throttle response. $99 and plus into the OBD port very simple.
