: 3400rpm in low range on an LMM........damnit DuramaxPowered 07-20-2008, 10:47 PM Am I missing something here......I have every limiting table maxed out, pedal position to desired torque low range set to fuel hard at 4000rpm, but I pulled today and 3400 rpm is it, won't go any higher. What is needed to crank some rpm from the LMM!!!!! ColbyColorado04 07-20-2008, 10:58 PM Did you have it in M mode? I know with my LBZ it will still cutoff if im in D. But in M mode I cant take it up past 4k. Its set to 4600 but i havnt had the kahhooonnnaaaa'sss to try it. dmaxvaz 07-20-2008, 11:02 PM Am I missing something here......I have every limiting table maxed out, pedal position to desired torque low range set to fuel hard at 4000rpm, but I pulled today and 3400 rpm is it, won't go any higher. What is needed to crank some rpm from the LMM!!!!! hey jeff- how did you do in the pulls? i talked to toman yesterday and he was thinking about pulling today with his red truck The Neens 07-21-2008, 02:17 AM What is needed to crank some rpm from the LMM!!!!! Have you looked at your stock TCM file? DuramaxPowered 07-21-2008, 06:39 AM hey jeff- how did you do in the pulls? i talked to toman yesterday and he was thinking about pulling today with his red truck 2nd out of 13.....muddy track, I pulled 236'. first place pulled 240' with a CC/SB LBZ DuramaxPowered 07-21-2008, 06:53 AM Have you looked at your stock TCM file? unloaded the truck will pull 4800rpm in low, but the fuel rate must drop like a rock after 3400.....:o: just looked at tcm file {D5197} looks like a problem, I'll change it to RPM LIMIT REQ DISABLED.........Thanks Neens vortecfcar 07-21-2008, 07:01 AM There are new 4 low tables for the LMM in the 7.5.4 release that fix this problem. I don't think the trans torque limit is the cause - another fella had this issue recently. I'd update to that one if you get a chance. :) Nick DuramaxPowered 07-21-2008, 07:07 PM Nick, I have 7.5.4 build 65. Is this the correct version? DuramaxPowered 07-21-2008, 07:48 PM in the tune that I used, I didn't match A,B, and C pedal position tables. I only changed the set of A tables since the description says Mode Band C "pedal response might be 'sport' or 'towing' mode etc if the vehicle has the ability for the driver to select different driving modes." vortecfcar 07-21-2008, 10:44 PM I think 4 low @ 4000 RPM qualifies as sporting :). Make them the same. DuramaxPowered 07-22-2008, 06:41 AM the way I understood the description, it looked like these tables were put in so that when DSP was available for LBZ/LMM these are the tables that it would use. A little confused from the description. Oh well, they are changed now.:D | ||
