Hey everyone.I'm new here. I know I should write more information about my problem, but I'll start with this.. We overhauled the engine in my Dodge Ram 1500 1996. He got a new timing, the camshaft was changed from roller to flat tapped( COMP Cams Xtreme Energy Hi-Lift Cam and Lifter Kits K20-228-4 ). Longer pushrods. The motor has been sealed, all sensors are new. It fires and works very well, but after putting in gear or when turning the wheels, the revs fall and goes out. What could be the reason for this, because we no longer know where to look?

 

Because the computer doesn't know how to run that engine. That's a pretty big cam.... You will need a custom tune to run that.

If you give it just a little bit of gas, will it stay running?

 

The engine starts without any problem and works very nicely even when I add gas. As it warms up after putting the gear does not keep the rotation as it should and goes out. Forgive me if you don't understand something, but I don't speak English fluently

 

We tried to tune it with the launch device, and for a while it was reasonably good, an hour it drove without problems. The engine turnover was still too low and we tried to adjust it. Unfortunately, the adjustment failed and the condition is as I describe.

 

Which Launch device do you have? 96 and 97 are kind of a 'hybrid' OBDII, so, not all tuners are compatible....

 

I'm not sure, a friend who has a workshop came to help me with this device. Can you tell me how I could tune my engine with this camshaft?Is there any mobile diagnostic device that can handle this?

 

HP Tuners makes software/Hardware (requires a laptop computer...) that you can read, edit, and write your tunes to the PCM. I do believe it does support 96 and later trucks. It is not cheap though, 600 or so US dollars for a license for ONE vehicle. (your truck, in your case) That would require YOU to make changes, see what happens, and go from there. There is also Hemifever tuning, or Flyin' Ryan performance, that will write custom tunes for you, (and make adjustments later) I think the price is in the same neighborhood..... Not sure how they handle overseas customers though. I have no clue if anyone outside the US does it though. Around here, there are even shops that will do that kind of thing... but, only in the larger cities. Not sure if there would be anything like that around you either.... Do it yourself has a STEEP learning curve.... but, I think HP Tuners, at least, offer customer support... but, not sure if they do any other languages than English. You do fairly well, so, maybe not that much of an issue?
