Thanks guys for all the help/advice! Lower radiator hose is done coolant is in fuel shut off solenoid connected properly now. Today I need to attach my cable to the throttle pedal and hopefully take it for a ride. I was able to get a friend of mine to make a couple of adapters, one is two and a quarter down to 2™ and the other 2-in down to 1.75 and then the final one to an inch and a half. They were all 4-in adapters out of exhaust pipe. So apparently now I need to have the computer reprogrammed to have the electric fans come on prior to the original 230° setting or whatever it is. I've already talked to a local shop who can take off the dash lights using his computer, so hopefully he can adjust the temperature setting for the fans also.
So far, just idling for several minutes plus driving it for roughly about 5 mi now it seems fine. But time will tell. I would probably do a few things differently in hindsight but I'm really satisfied with the outcome.
Update, just as few odds and ends left but it is now drivable. I'll probably be fine tuning and upgrading for years to come 😁. I have driven it around town, to the alignment and exhaust shops. It's great, very happy with the 4bt/NV4500 setup.
Nice build. I went the VW TDI in my 08 JKU and its been fantastic and 29 MPG.
I'm interested in how you made out with reprograming the JK ECU to get rid of dash lights? I need to find someone to do that to my 08 Dakota ECU with the Cummins ISB170.
Good morning all! The guy I went to had been a master Chrysler tech for 25 years and is now running his own shop. I'm not sure what software he was using but the cost to unlock the computer was $100 and the end result was unsuccessful... He wasn't able to turn any of the cluster lights out. He thinks he was able to turn the fan temp setting down but I haven't confirmed this.
This has been my experience as well.
Some of the tuner guys can actually get into the layers of the ECU programing and turn on and off sensors and outputs but even the expensive software that I have which allows me to turn on and off some stuff does not get deep into the programming. People like Bruiser Conversions who do Jeep engine swaps can do this work but my experience with them so far has been no reply to any emails. I think the guys who use HP tuner software can do this sort of work but I have not explored that yet. The JK ECU is the same basic one as most Dodge products like Ram 1500 and Chargers which both are common to the tuner guys. On my TDI swaps I use Malone tuning and he can turn off any error code that the ECU generates, he turns off all the sensors that I dont use in a swap so no error codes show up on a scan. We just need to find someone like that to do the Dodge/Jeep ECU's.
Yes. I'll keep looking around and hope to find someone that can do it. I do have a connection with our local Jeep dealer so I talked with them the other day and was told that their equipment is unable to turn off the lights also.
Sounds great thanks. I just installed a 40hp fuel pin and turned the fuel up, had to turn the idle down. I think I need to add a spring to the throttle linkage because when shifting the rpms don't fall off very quick.
A little update! The Jeep cooling system is done, alignment done, exhaust work done! I added a 40 horsepower fuel pin because it did seem a little sluggish. So when I tore the fuel pump top off, the diaphragm and fuel pin or seized which probably contributed to the laziness of the motor. It runs a lot better with the new fuel pin and everything being freed up. The issue I'm having now is the electric vacuum pump and additional vacuum canister is not adequate for the braking system. It loses vacuum after two pumps. So I may have to look into a manual vacuum pump. Any ideas or suggestions out there?
1994 - 2002 Dodge diesel (6bt) vacuum pump - it is gear driven and the power steering pump hangs off the end of vacuum pump. NOTE: A simple bracket MUST be fabricated to support the end of power steering pump - it will snap off without support. I've posted pictures a couple of times - don't have time to look it up now.
Used this assembly in my signature truck. First vac/PS unit came from a friend's junk pile. The vac part eventually started leaking and I replaced the VAC assembly with a Dorman assembly
