@Days that End with Why Sounds good, it has been tested for 6 months before I released it so you will be happy. Let me know when you are ready for a copy.
Great video! And thank you for posting engine and trans tune and breaking all the numbers down!! And yes your engine and trans tune on my 5.3 and 6L80 is working great!! Love the way you tuned my tow haul, coming into 2nd hard breaks tires loose every time if you want it to!
So my vehicle is an odd one. Its 2002 Blue Bird Bus with an 8.1L gas engine with an allison transmission. I am using this bus for my business. It is pegged out at 55mph right now and I ordered the HPTuner to adjust it myself (because no one else knows how to in my area). When I hit the accelerator past 34% it starts to bog down. Fuel pump, air filter, and fuel filter replaced. I have changed the max speed and a few simple items for the tune. I am not increasing over 500hp for the bus. Would the rest of your tunes work for my application?
@mikeicnd1, I would use HPTuners to datalog the BlueBird as it sits right now. It should not be responding by bogging when you put your foot in it. Tunes only work when everything else is perfect so I would run the "Diagnostics and Info" button in HPT to check for active or deleted codes then run a datalog with HPT to zero in on the problem, use the misfire detection setup I show in one of my 8.1 troubleshooting videos as well. I will be happy to share my tune as its been proven over time, but it wont work with other items out of sync. Email me at mymusiconmyiphone@gmail.com
The engine part will definitely work and apply the same transmission techniques to your 6 speed - decrease shift time, increase shift pressure if you like. The torque management is the real trick, it wakes these engines up and lets them roll.
where are you located and do you tune other peoples trucks? i have a 02 8.1/allison and would like to have improvements like yours. im by traverse city mi.
Tuning question. I had my 8.1 tuned at a local tuner. Ran great. But at around 3rd or 4th gear when I let off the throttle I get a surge as if I gunned it real quick. Then it slows down as it should real strange but scary
Its interesting that it only happens at a higher gears or speeds. Send me an email at mymusiconmyiphone@gmail.com I will send you my tune and you can compare it to your tune. Maybe you can troubleshoot the error just by seeing a different tune. What does your tuner say about the surge?
Great video breaking everything down! would love an update on how the tune is preforming and if you have changed anything with it. Also are you still emailing the tune for people to try, if so I'd like to try it out on my 03 2500hd
The tune has been in my truck for about 2 years so its a safe and proven tune. Email me at mymusiconmyiphone@gmail.com and I will respond with the base tune.
i would love a copy of that tune. what is your email? do you still have that truck and if so is it still running the way you want it to? I am getting a dyno tune next month and i think they use that same software with their dyno.
@@paullaranjeira5035 email me @ mymusiconmyiphone@gmail.com and I will be happy to share it. I have gotten great feedback from everyone who has run the tune in their 8.1 8100 Vortec.
I would love to get the tune from you as I am attempting to tune my 8.1 currently and I would love a good base So the only things I would have to change is the trans stuff because im running a 4l80e
@Noah Guernsey Sure, send me an email to mymusiconmyiphone@gmail.com I will reply with the tune file! This file will contain the Engine and Trans tune.
Will the base tune be different if im running an nv4500 manual transmission? Or is anything different at all? Just tune motor and skip transmission portion?
I would tune the engine save and test. Then look for settings in the transmission section that affect torque negatively and eliminate the reductions then test again. Saving the engine portion first will keep you from chasing your tail by changing too many parameters at once. Email me mymusiconmyiphone@gmail.com for a base tune to compare with.
@@CarswellsCustoms I should rephrase. Will, YOUR, base tune be different if its run in a computer thats always been a factory manual transmission computer? Does a oem manual trans computer even have provisions inside for automatic transmission?
@@hardhead7056 Yes and no. You can flip a switch to enable manual transmission but It still wont work until you add the "Segment" or manual transmission code to the ECM. So to make it easy as possible, use the compare function in HPTuners, open your tune in HPTuners editor and then open my tune in the "Compare" function. Change your parameters to mirror mine in your engine tune. You will not be able to Drag and Drop my tune, you have to change the fields individually. After changing the fields, then look over the trans section. This all sounds harder than it actually is, so just get to it!
HELP ! Greetings , I have an 02 2500hd and was thinking of swapping out the 6.0 ls for an 8.1 out of an 03 Avalanche , so will be running the 4l80 with 4.10s ,cable throttle body and egr delete . Will this tune work for that set up ? Am wanting more low rpm towing power would a tune on the 6.0 ls give me much ? Thanks for any response .
Yes, the fundamentals for the DBW and Throttle Cable are similar. The Allison Tune is not the same but again the same fundamentals can be used such as shortening up shift time and upping pressure when the shift is applied. Did you swap the ECM to a Cable Throttle compatible model?
@@CarswellsCustoms Haven't done the swap yet , just bought the motor so would be using the original computer , the 02 has cable throttle . Edited my original post
@@user-wj9wq7mk4h it went good , pretty easy after all said and done. The low end torque is awesome , got a performance tune from Black Bear and added dual electric fans . Glad I did it
@kbitbit I see there is 60 seconds of delay still in the tune. Datalogging has proved otherwise, maybe there is a logic tree that the 60 seconds are dependent on the RPM first. Great catch! I will change it for consistency.
@Gladen Rexroth at 10:29 removing the torque limitations in the engine tune will help. Also in Trans tuning at 14:57 allowing max torque will also help. I have not dyno'ed the tune changes but applying this tune makes a real difference. On rainy days you have to pay attention!
@@CarswellsCustoms once I get 6.7 inch rods and forged 4.310 pistons I'll be putting my old 05 C5500 Uhaul truck to work. I think I'm rated at 320/440. Like to see 350-375/500+. Hoping that with a power increase, a 6 speed conversion and taller tires to get a little bit more economy. I drove it at 55 mph 190 miles home and got maybe 7.5 mpg. Hoping to see double that in the near future. Kilduff has a manual valve body shifter for the allison. Hoping that with shift manipulation it may get even more.
@xpose5821 An aftermarket intake and a free flowing exhaust will improve efficiency. In HPTuners you can reduce the shift points per gear. Do you have HPTuners or have a friend that does?
@@CarswellsCustomsI removed all torque managment but around 30-50% throttle the shift is a little harsh . I pulled shift times down to 0.30 and shift pressure maxed out.im thinking about going stock shift pressure and stock shift times to combat this. Or can I add in some torque managment to help combat this?
@@xpose5821 The stock timing is very aggressive and that is why I don't add any spark timing. The computer sparks the hell out of the engine and depends on the knock sensors to pull back timing to safe levels when knock or pre-ignition is detected. When you are tuning and you throw a ton of settings in at once and get a poor result take all related settings back to stock and change items 1 at a time by 10 or 20% and test.
@Raymond Felton Copy the settings from my tune to your tune in HPTuners. Use the Compare function in HPTuners so you can see exactly what to change. Let me know how that works.
