Jeep Grand Cherokee CRD
New to Forum - Jeep WK CRD
Hello,
I am new to the forum and wanted to say hello and thank everyone that posts info on the om642 engine. I have a 2007 Jeep Grand Cherokee with the 3.0L CRD engine currently with 52,000 miles. I think it's a great engine and happy with my purchase. I have owned the vehicle for almost a year and it has given me zero problems. It is my wife’s vehicle so I can’t mod it as much as I would like. I have performed several reliability mods. I have done the Elephant Mod which is venting the CCV to the atmosphere, swirl motor issues. I performed a dpf delete with a Custom Spooling tune. I am enjoying the ~ 2.5mpg gain and additional performance since January. I changed out all the fluids with amsoil fluids. I would like to add an oil-bypass kit and secondary fuel filter. I have owned a modified 2004 Ford F250 since new and that is most of my experience with diesels.
Thanks.

Thanks. No problem, last year I contacted Custom Spooling to get one of their dpf delete tunes. I did a lot of research on dpf delete tunes and liked what I heard when talking with Custom Spooling. I ordered their handheld tuner and loaded up their dpf and egr delete tune. This tune disables the regneration cycle and keeps the egr valve closed. I made my own dpf delete pipe to replace the dpf pipe incase I want to go back to stock. I removed the dpf sensor tubes, but you need to keep the sensor plugged in. My wife never new at first the Jeep was tuned. It is barely louder than stock, I noticed it, but I was listening for it. I would say it has a little more of that diesel clank sound. The exhaust is still very clean, no black soot on hard acclerations. A little more diesel odor, but not very noticeable.
I plan to run some more 1/4 mile drag times this week now that weather is getting nicer. Stock I ran a 15.8 1/4 mile at 83 mph. The tune has a lot more power, but very linear. The turbo lag is gone compared to stock. I have not dynoed the tune so I can't give an actual power increase. The same tune on a different Jeep GC CRD made:
Stock HP: 152.8
Tuned HP: 206.5
Stock torque (FtLb): 282.8
Tuned torque (FtLb): 348.3
+53.7 HP and +65.5 FtLb

I have been running the Custom Spooling tune since January and finally got some time to play around with my bullydog watchdog. When I bought the vehicle I did some 1/4 mile runs. I got around to looking at my tuned ¼ mile times vs stock. I have an economy/performance Custom Spooling tune. It runs awesome with plenty of power and still rocking a 2.5 mpg gain on city driving. This is my wife’s vehicle, I believe it could be better, but she likes to use the extra power. The first picture is of the stock jeep on a 1/4 mile run with ½ tank of fuel and 40 psi in the tires via the tire sensors.
The next picture is of the Custom Spooling Tune ¼ mile run, all stock except the tune. I made sure I had ½ tank of fuel and 40 psi in the tires via the tire sensors.
I was hoping for a better 60 ft. time, but I can’t make full boost in first gear. All ¼ mile runs were a non-boosted launch. I based this on my wife will not run a boosted launch so I wanted it to be representative of her driving style. I run several ¼ mile runs of each version so this isn’t just one time only. All similar runs were almost identical.
I would like to get into the 13’s with this Jeep. That should be fast enough for the wife and keep the 10 month old daughter smiling. The next thing is a water/methanol injection setup and then an actual race tune from Custom Spooling. I’ve run h2o/methanol injection on my F250 for a while with no issues so I don’t see any issues with the Jeep. Plus it would help clean out the intake manifold now that the EGR is deleted. It will be on a switch so it can stay off if I want.
