[QUOTE="drunk on diesel, post: 1075362, member: 2558"] That's all very good information. But if the truck is shifting at 3900rpm at WOT on the 3-4 shift and he has the desired WOT shift RPM pulled to 3000 or even 2500 and he pulls the desired OSS at 40, 35, 30, etc. and NOTHING changes on that ONE specific parameter? there's a bug in the software It's a big program and H&S isn't a big company. Nothing against them what-so-ever! But they have had a few glitches here and there in their normal tuning and with the MCC setup. They are very proud of that program and are happy to learn of and fix glitches like this. to the OP, is your truck a Job 1 or Job 2+ Maybe I could send you some files that DON'T exhibit this shifting characteristic on MY trucks, and if it continues on yours, then we know the problem is with your truck (TCM?) and not the MCC software [/QUOTE]
