Just as a little update, still got the cherokee to pass inspection without the NSS hooked up. Just had to do it the radio shack way. VAG-COM lets you read readiness and all that so you can know if you'll pass/fail before hand. I tried doing some logging in it but I had the same problem as with...

Yeah over two years ago and it broke into a bunch of pieces. Bought new one two years ago, installed...worked for a little while then it stopped working. Last year I ghetto rigged it to work for park, "reverse", and drive so no code, etc etc. This year is going to be a little more interesting I...

Good guess, but I keep cats unless some other people on the board. ;) My problem is the NSS, been the bain of the existence of this jeep since as long as I can remember. The new sensor (as of two years ago) is stuck on there now and isn't coming off. I'm not going to get a new one or one from...

I'm more or less looking for a way to permanently set a particular problem for a check engine light to be off. :dunce:

What is the "brand" (i.e Bosch Motronic, etc.) of the ECU in a 98 xj with the 4.0. Has the california emissions package as well. Anyone know how to hack into it? Any dtc checking programs (I've asked before but cant remember where). Kinda vague but any help is great.

If you can do it cheap enough, regear. 4.10's on stock sized tires will make you feel a lot faster. Other than that, never pay full price for any performance part cause the cost/benefit usually isn't there. A lot of people on here are saying stroke it but unless you can find a deal on the...

I'll try to knock this out in one post. The xj is typically 3300+ pounds. Not too heavy but not as light as imports. With the AW4 (even worse is anyone with the 3spd auto), it has all the losses associated with most automatics vs most imports have standards. 4wd jeeps also have extra...

My 1.8t's got more tq than a 4.0 at low rpm. I wouldn't hook it up to the vw body though. I weighed my 4wd 4dr xj before and it came out to 3450lbs. Dunno where you all people are putting 200hp and turbo together? The VR6 is a different engine. 2.8L, basically an inline 6. They shouldn't all...

1, yeah 2, they dont rev that high (I dont shift my 1.8t past 6500, a vr6 maybe 7k) 3. aerodynamics are rather insignificant in 0-60's 4. dohc or not, it's still 200hp 5. 200hp is the 2.8 vr6, 180hp is 1.8t 6. prolly stick If you look around some more OP, the Jeep is usually low 8's for the...

I dunno how much the jeep's can correct the fueling when in closed loop, but when you floor it, the vehicle goes into open loop and it won't rely on the o2 sensor anymore (which I believe would be the only thing to correct via the fuel trims). When WOT, in open loop you'll be running off the...

Nah Im mainly looking to do diagnostic work for it. Tuning is for turbos not mostly stock jeeps. I love the work I can do with my 1.8t and i think that software that Mosephus linked looks pretty good. I'll let you guys know how it works out. Thanks again.

Anybody know some good freeware for our jeeps? I have a vagcom cable (for vw's and audis) but I guess it works as an interface for our jeeps. Mainly looking for something to figure out and possible erase p-codes but it'd be cool if there was something I could tweak the jeep a little. Thanks in...

I like to keep the stock box on most vehicles i have whether the jeep or the vw. When you cut them up (which i did to both), sounds pretty close to a short ram / cold air intake and gives comparable performance. Especially with puddles and/mud is it worth the extra couple hp to have an exposed...

Make sure it's on perfectly flat ground ;)

SRT-6's are actually supercharged. Same as the SLK32 AMG.

Looks pretty good. Where did you get that wrap?

Yeah but he said it's non-HO...so it'd be 235hp. I'm not sure which 4wd/awd system he had but it's bound to have more drivetrain losses than the XJ (at least i'd think). I can't say it's the most impressive thing to beat....especially with the 5 speed in the modded xj. As far as those 0-60...

Just saw the link now. I like that website a lot for info but vids or timeslips are the only way if it's from a private party. I second what Talyn said about the fluids. A sharp turn like that will cause you backpressure... party1:

It'd go over smoothly, not such a sharp change in direction. And as far as you thinking you can get into the 15's. See the other threads on here as to what people actually get with their mods. Just because such and such magazine says say 8.2 seconds to 60 and 16.2 in the quarter (what motor...
