Message: [QUOTE="Marauder, post: 104096, member: 1349"] Thought I share a lesson I learned today. I've been chasing my tail for the last two weeks trying to find the source of an engine miss at part thottle as well as some extremely rich conditions. So I started running things down. My AE hates my laptop so that was useless point of information. I do have a scan gague and it showed the ICP pressures bouncing around from 550 to 630 at idle. So I replaced the IPR and ICP sensor at the same time. Things became better but the miss went away when the engine was cold and as it warmed the miss became worse. I'd say it made the truck run about 40% better. But I still had the miss and smoke from hell. So I started reading again! Wiring harness and UVCH came to my mind. Although I have no CEL. It idles fair runs strong without a the miss. Check my sig for engine specs. So now I'm thinking I have a bad TS chip from Beans. What else could it be? I see the post here about Swamps IDM and head over to their page and read up on their product and what a complex black box it is. The thing that struck me the most was they noted that the IDM units got slower as they aged! Mine had 244,000 miles on it. The truck started right up every morning and ran strong with my GQSSB....but my 250/200 are asking for a pretty narrow window to fire in.....I wonder? So I head over to Strictly Diesel here in Phoenix and to my surprise they stock the Swamp Modded IDM...Cool! After the install...... I still have the off load eratic miss when hot, but it a lot less and the smoke is about 70% gone. Which now means I don't have people making lane changes behind me when leaving a stop light. The engine runs in a much more precise manner. It was like going from points to and digtal igntion system. The lesson here is that if your going with a injector that requires a better quicker signal, don't over look the IDM. My IDM was a 120 it ran my stage II injectors fine and I bet you could put it in a stock 95-97 and it would run great. It was when I changed the injectors and turbo that the **** hit the fan! I read that IDM's never fail or rarely did. Water wasn't an issue either as my truck resides in AZ. No one ever mention that they grew weak over time....just the guys over at Swamps. Thanks for doing your homework!:thumbup: Now I need a new Clutch!!!!!!:wtf: Along with some live tuning! Whew!!!! [/QUOTE]
