96bulldogpower Posted January 7 Share Posted January 7 Hey guys, I’m hoping to get some help with a rabbit hole I’ve gone down with a 2007 Mack CV713 AI 400. This is a triaxle dump truck we just put together, when put into service we discovered it is absolutely gutless, it was pretty much unusable for what we do. Long story short, we’ve been throwing parts at it in an effort to make some power with it. The problem is that our local dealer is useless and won’t uprate the horsepower. So we bought a ECM from a 2000 CH 427hp engine, we knew we wouldn’t make power with any of the available ASET AI data files anyway so we’ve decided to take it back to an etech ecm. The truck has gained a bit of power and is now usable. Unfortunately the donor truck we pulled this ecm from did not have engine brake and apparently didn’t have an air fan clutch because the fan will not turn off anymore. My question is, will a tech tool with V-Mac III software be able to turn on the air fan clutch and engine brake functionality in the parameters? Or is there such a thing? If so, I’ll be purchasing a tech tool very soon. list of mods to truck: etech exhaust manifold, s475 74.5mm turbo, 460HP ASET injector nozzles, ECM from 427 etech, 3.65 rear gears as a side note, the truck runs considerably better, has more power throughout the power band. But it still feels sluggish, we have a similar spec’d ASET AC truck with 355/380 ECM with K&S injectors and the same gear ratio and it pulls HARD compared to this troublesome truck. Is there any other modifications I can do to this AI to make it have more power? Quote Link to comment Share on other sites More sharing options...
