Was everyone using the MVPI2 or the original MVPI interface?

Is it worth doing a full write just in case?

The other concern I had is that I updated to the latest version of VCM Editor. Will there be any issues with using the original MVPI not the MVPI2?

I have the MVPI and am getting ready to load a modified tune but I am freaking out about bricking my ecm. I have made the modifications on the last tune that I loaded into it 4 years ago and worried...

Ok, I have made some changes to the tune. I am trying to back it down from the 100hp tune and shoot more for economy and adjusting for the new 50hp injectors. Can you guys look it over and see if I...

Hey dhoagland, can you post your 50hp tune again? For some reason its not showing up in the post thread.

No worries, dhoagland! No offense taken! I do know how to use the compare function and appreciate the 50hp tune. The tune I posted originally I have had installed and running with stock injectors...

Thanks dhoagland, I have already rebuilt my trans to handle 500hpish. I do have a boost elbow that was set for 35psi for the HE341. I was planning on setting it for 40psi for the HE351. I...

Thanks Jaeger for the info. I am glad there are guys like you that keep pushing for more tables to be loaded for tgeae older trucks. I would love to get some trans tables from the tcm put in!

Thanks Boostjunky, I was more interested in if anyone had any input on adjusting the tune.

Anyone?

When I open the tune in VCM Editor, click on the engine tab, it has the idle, airflow, fuel, diesel fueling, diesel timing and torque management tabs across the top. The diesel fueling and diesel...

Hey all, Attached is the tune that I have been running for the past couple years. Due to a head gasket failure and a couple of crack injectors I have upgraded the turbo to a stock HE351CW and am...

All,

Is there anyway to get the speed at which the torque converter locks up added so it can be adjusted. This is for the 2003-2004.5 305hp Cummins with the 48re trans. From what I have found...

BigCE, I left my laptop at work so it will be a couple days before I can post the log but I ran the truck with a copy of your tune and all I can say is WOW!!! It is like driving a completely...

Will do, I will post up a copy of the log tomorrow.

Thanks BigCE, I will flash the copy of the tune with the patch applied. Electech, I had read that thread but it didnt really specify how it affected previous versions of the tune

I was comparing my tune with another tune and noticed the other tune had an extended datastream listed in the OS. I hit the button to see if there were other items available and the warning popped...

Hey BigCE, I was looking at the pilot injection timing correction tables and you had made a change to the Baro multiplier. I tried to duplicate it in my tune but I cannot get my table to go above...

haha, I hear ya.....thanks again for your help!

That's kind of what I thought. Thanks for the follow up Bill!

Thanks for the tune sharing. It is good to see I was headed in the right direction. It definitely helps to see a working tune and where changes have been made. Is your truck a '03 305hp? Any mods...

I changed the Boost Limit A map to mimic yours and maxed both Baro tables to 200mm3 across the table. I then maxed out the Torque Limit Tables to 2048. I also disabled the BTM, General Limit A,...

I am tuning my 03 Cummins and the only option listed under the flash tab is Write complete. I have looked all over and cannot find the Write Calibration option. Anybody know if it has been disabled...

Hey BigCE, Here is an updated version of the tune. I have made several full throttle runs with no smoke at all. The throttle feels like stock with a stronger pull, not touchy at all. It still...
