RENIX - ECU's

[RLCollins]

What year, and model vehicles, can we pull the ECU's out of, that will work properly in an RENIX system? :help:

Jeeps of the Renix Era.

 

There are 4 different Renix ECUs

 

86-90 2.5 w/ automatic

86-90 2.5 w/ manual

 

87-90 4.0 w/ automatic

87-90 4.0 w/ manual

 

4wd makes no difference.

So you are talking about jeeps with 4.0L engines manufactured between 1987-1990, or 4 cylinders btween 1986 - 1990 . Does this look about right? :hmm:

[Geonovast]

Correct... you can only use an ECU for your motor/transmission in your year range, out of an XJ or MJ. I can't verify that the 87-90 YJ 2.5 is the same ECU, but I can tell you there is no such thing as a Renix 4.0 YJ. They got the carburated 4.2 until the introduction of the 4.0 HO in 1991.

You can use an ECU from a 4.0L manual in a 4.0L with an automatic tranny, and vise versa. Perhaps not optimum, but it'll run and you'll probably not be able to see/feel the difference from the driver's seat.

Thanks; both of you for narrowing my focus on what I need. I am building a spare parts inventory while the quantity of JEEPS from the CASH for CLUNKER vehicles are still in the bone yard. It seems that these junkers are moving very fast, The junk yard has to crush them in a certain amount of time, and it seems that time is running out. So I am trying to build a surplus of parts for repairs. What would your extra parts inventory look like? Another words; what are the most problem prone ones that you would want on hand? :idea:

I grab any MJ specific parts, needed or not... Fuel Tank Sender, Taillights, Rear wiring harness, Fuel filler neck (I think this is MJ specific), rear driveshafts, B-pillar and cab trim, etc

[RLCollins]

Thanks for the information. Where is the fuel tank sender located? what is a b-pillar? What's so special about the fuel filler neck. People call me a RED-NECK, and I know what they are refuring to, a patriotic AMERICA CITIZEN who believes in the Constitution and what the intent of the Founding Fathers had in mind, when they created the Constitution, and will defend AMERICAN till my DEATH. :bowdown:

But what about a Fuel filler neck? Educate me please :dunce:

[whowey]

Fuel filler neck.... the piece that runs from the place you put the gas nozzle to the gas tank...

 

B-pillar.... The part of the cab right behind the front doors. A Comanche only has an A and B pillars. The A -pillar is the part of the cab by the windshield. An XJ may have a C-pillar or a D-pillar. Start at the front of the vehicle looking at the side. The part of the cab infront of the door, holding the windshield is the A-pillar. Now just count them off going back. behind the front door is the B-pillar. If you have a 4 door vehicle.. the part behind the back door is the C-pillar.. etc....

 

The fuel sender is inside the fuel tank. When you pop off the hoses and retaining ring, the part that slides out is the sender and the pump rides inside the sender.

 

The reasons they tell you to grab this stuff is that it is all Comanche specific. It wasn't used on any other vehicles that we(as a community) know about. So it is hard to find in usable shape.

Yes for the most part you can no longer purchase these parts new anymore. (They randomly appear on ebay once in awhile listed as NOS- "New Old Stock")
