What company did you go with to get yours? and did they offer any tunes for the vans or did you have to make your own?

Tanc Crusher 01-08-2009, 05:47 PM Give Nick a call at duramaxtuners.com. Only one I have dealt with EfiLive. Not sure if there is a big difference between van and truck. I do know lower HP/TQ on van. No idea if the OS on the van is anything close to the truck versions. Brian ShopSpecialties 01-08-2009, 05:53 PM They are different. Tanc Crusher 01-08-2009, 07:44 PM Figured they ran different OS releases. And probably different ECM maybe. Probably also no seperate TCM since no Allison. Brian lotsofmiles 01-08-2009, 07:49 PM Nick told me he could do the van. Dont know if he has tunes already, or was going to make it. I haven't gotten efi yet... ShopSpecialties 01-08-2009, 08:06 PM Nick told me he would use a modified truck tune. I tried to use a stock truck tune and there was to many issues. I know EFILive said there was a couple of tables that were different. ShopSpecialties 01-08-2009, 08:27 PM Same ecm and yes the 4L85E has its own puter. Tanc Crusher 01-08-2009, 09:55 PM Thanks for the info ShopSpecialites. Glad to know how the vans are setup. Just did not how cumputer wise since using the 4L85E transmissions. Yeah just get hold of Nick then. Great guy. Brian stefdogg 01-09-2009, 02:24 AM I would like to no more about this. What is the cost going to be? EFI Support 01-09-2009, 06:01 PM The ECM's in the vans are the same as the trucks, however they have different table layouts which is why in many cases a standard handheld won't work. The van uses the T42 TCM which you can tune with EFILive. You should be careful when adding power to the van, the 4L85E trans is very different to the Allison and can't hold as much power.

Cheers Cindy Some of 'em cant handle ANY power....:cussing: ShopSpecialties 01-10-2009, 01:20 AM I bet it was the bugshield that broke the tranny. lotsofmiles 01-10-2009, 08:09 AM I'm surprised they didn't blame it on the 'oversized' tires. Good thing it was making noise before the tires went on. Joey D 01-14-2009, 11:03 PM What size tires are you running? I would like a taller tire next time around. lotsofmiles 01-14-2009, 11:10 PM I think I started a tire size thread a while back in the van section... I put on 265/75/16 They are about 1 inch taller a little wider and look better imo. here it is: http://www.dieselplace.com/forum/showthread.php?t=278966 | ||
