I have an isx15 2350 engine. I'm not sure what's going on with the acceleration from 9th to 10th gear. 9th gear won't climb past 1500 rpm and change to 10th gear it falls back to 110p - 1200 rpm and lugs the shi#t out of the engine before getting back over 1450 rpm. I have Cummins insite is there a vid or does someone know how to change the parameters so 9th can climb over 1500 rpm before shutting off, and accelerate quicker in 10th with less speed? 10th gear is only 1500 at 70-75 mph and and 13 at 65. I'd like to be at 65 max speed but 1500 rpm. Hope this makes sense and any help would be most obliged.

Mine is the same. Only goes past 1500 for a few seconds when pulling a hill. I have insite but don’t know what to mess with. Don’t want to mess things up

Grow some balls, do some reading, ask some questions and get rid of your problems. Stop being paralyzed by a lack of knowledge. We were all there.... until we decided not to be.

Delete the ECM value for gear down protection, like Rawze said. The shifting is like a dream. 9th gear can go from 45 to 65 now 65 around 1800. Although, I am curious as to why they set the specs the way they did... Not a response as like they are f**k tards. Did they think the driver would not pay attention and run over 2000 RPMs in 9th, or was there problems with the designs of the isx15, that they thought it would be better to set the gear down at 55 and 71??

it is to prevent the company drivers form utilizing full output power of the engine.
