Default ECU ?? how to test it??

I have had some issues with my truck for some time now and just yesterday, I found that my ECU may be bad.

the rover tec swapped out my ECU with a unit he had at the shop he had me drive around and see just how it reacted.
well my old codes that would have come up Did Not..
the rover tec said, its you ECU but try these two things first before you replace it..

1. clean connectors with di electric grease
2. open the case and clean with electric parts cleaner.


so I went home and started at # 2
when I opened the case I seen dry mud on the side walls of the case not much but I guess hat was their could have done damage.

so I sprayed the cleaner all around and scrubbed with a tooth brush.

put back together and took for a ride.

I just don't know...
yesterday when I drove to the rover shop some 20 miles away the truck ran strong.

when their it even acted funny up for the rover tec to see and make his suggestions.

and after I cleaned the ECU it ran rough for a mile or so than went back to running good. but gave two NEW CODES P 1313 & P1314


????? is it the ecu or some thing else

any thoughts from the rover owners of the world.



( my wife said if I get rid of my rover I can have a girlfriend it would be cheaper)

Rudy,
There is not alot you can do past cleaning, checking for burned connections on the boards and making for good connections. If the other ECU made the truck run well, sounds like your last step will be trying to buy that used ECU.
You most likely have caused a part to fail do to all the dirt, and tracking something like that, much less getting new parts and replacing them is probably something you can't or won't want to do.

The LR ECU holds certain "internal "codes that don't come up at the Check Engine Light but can be read by a Autobook The new ECU is not expecting to see your oxygen sensors and were running in another car and the codes are popping up because there was no retraining time. Reset the ECU and then run the car for awhile.. I would reset the ECU with a Autobook and then see if the codes reappear.

I have a damaged ECU (it does not see the oxygen sensors) and have two replacement ECUs but I can only run them for two engine starts before the LR copy protection kicks in. Then I have to swap the old one in to get the 1996 D1 to start.

Would like that to work.

thanks,
Presumption: You have a Land Rover. You have to reset the ecu. A little history first.

About 1996 and later, the Land Rover (and most modern autombiles and trucks) adopted a standard called OBD II (or two). OBD II was implemented and allows for an automotive technican to get an more informed idea of what is going on inside the engine, dynamically, using a codereader or a laptop. You see a bunch of error codes and based on what kind, you can make an more informed guess of what is working/ not working/ not working well.

Now for the inside deal, fellow LRO member. There are codes that can be universally read by a OBD2 codereader and there are factory codes that only a Land Rover codereader can decipher. (For example, with a Testbook or Autobook, it can tell you if you have a defective thermostat awhile a stock OBD2 would not know how to read that code. It is part of what is called manufacturers codes.)

What can you do? Well, you can try to buy a testbook. It is an EXPENSIVE tool.

Or you can find a shop with one and then read off those interesting and hidden codes and then reset your ECU.

Can you reset your ECU? Yes. It helps if it throws a code first. Most if not all codereaders will not reset a ECU unless the Check Engine Light is first on.

Any more questions? Here is some reference on the Net.

I looked at the 'virtual tour' which was just pictures of the screen- it doesn't look all that hot. The air suspension part seemed as if you can't test the suspension, but just look at the values from the sensors. The engine info didn't look like it provided any more than a $140 scan tool. If it can program keys and change BECM (they called it BECL) options, it would have some value- but it doesn't look anywhere near as easy to use or capable as the autologic or T4 etc. I'm betting it ain't cheap either... I dunno.

Damn, Steve, I want to fix my Rover and you want a PSP to play with. If I can afford it, don't you think I want it?

I personally need to reset two new replacement ECUs to my BECM and I can't without spending a small fortune. I have two spare ECUs and I cant use them on my D1 right now.

What are you looking at? An introductory virtual tour. I don't want to be in your shoes if the stupid tour was about a new Land Rover.

Damn.

I'm afraid that didn't make sense. Was there a price posted? I know their BMW unit costs as much as an Autologic but with less function.
If the Rover version is affordable, it's probably fairly useful... Wouldn't it be cheaper to just have your ECU's done by a shop that has the tool and just pay them for the time?
All I'm saying is that without price info- it's hard to tell if it stacks up against the other stuff out there.

We can both agree on that.

I am looking for a affordable tool to solve my problem on my end, a bad ECU. You are looking for a fancy box that can double as, what I don't know.

If you think there are any dependable shops in NYC, I can tell you as a used Land Rover owner, they are as scarce as hens teeth. Or RoverX's virginity.

Right now, it would be nice to fix all this with a laptop. Sigh.
