Any high range gear foot to the floor and I can make it do it every time. There is a way to find out why the ecm is holding back the power, etc. by monitoring the main engine control state data in Calterm. A person can use a desktop recording software like 'OBS-studio', etc.. and then use this screen file in Calterm to record what is going on live wile on a test drive and it acting up.... For the CM2250: http://rawze.com/publicfiles/temp/zz-BBZ...cr.xml.zip That would tell you exactly what is controlling everything at any given moment. The most important setting to monitor of all being the 'CBL_Fuel_State' setting. Next to that would be the boost, VGT positioning, Turbo speed, engine rpm and torque, etc. in the screen file while going down the roads. At this point, I would even be curious myself, as this does not seem to be a normal situation for a CM2250. If the truck were here, it could likely be found right away by using that test screen + getting a feel for how it is driving, etc. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||
