ORM Board Kit (please update your payment)

LocoCRD · **Posted:** Wed Jul 04, 2007 11:55 pm

OK fellas. I would be willing to order the components and boards and put together kits that you guys could assemble for $65 dollars shipped. Canada orders might be a little more to cover shipping. If there are at least 30 of you who would like the kit option let me know as I am ready to place the necessary orders to make this happen. We will of course split the cost of Turbo Tim's kit as a thanks for pioneering this mod. I am starting a new thread called ORM Kit. Please add your name to the list there if you want to go for the kit.

OK questions already. Here are some answers I hope.

The kit will include everything on Turbo Tim's parts list as well as a PCB to put the parts on. All that will be requierd will be a soldering Iron, Solder and some cutting to fit the connector in the housing as well as mounting the resistor to the housing. If there are a few of you who can not do the build or do not feel comfortable PM me and we can work out a price on a built up kit where all you would have to do is splice in to the various connections in the CRD wiring.

Would you give a real quick summary of what the kit does. I know it was covered in detail in a prior thread but a recap may be useful. I would be more interested in a plug an play version over a kit.

tks

add me to the list,

one other question, is the housing also included, I don't remember it listed on the parts list from a few weeks back.

thanks for getting this together!

In Turbo Tim's words...

The ORM circuit is an electrical equivalent of the two controlling valves (EGR & AFC), this all fed by the MAF, to keep the computer happy, while none of the real components work, thus keeping the intake clean. Now I want to point out that this is strictly for off road testing only and that I never would suggest anyone else do something they shouldn't.
The circuit that I am currently working on is a great sprinkler timer modification, but it could possibly fool the EGR requirements for the CRD too.
The problems from what I have gleaned from all the posts is how the resistors were added in between the MAF and CPU. The problem is the MAF drives an analog voltage to the CPU. The input side of the CPU usually has a pull down resistor so it can detect if the wire breaks. The input usually goes to an analog-to-digital converter to feed the processor. The problem is/was that by adding resistors to lower the voltage, it changes the input impedance and throws the scaling off. I plan on using a few OP-Amps so that the loading/scaling stays the same until the EGR & AFC signals start to have their input effect.
The other problem with using relays on this line is that when it switches from one resistor to another, for a short time, this line goes open, thus upsetting the CPU (open is a fault condition).
No guarantees here, just a lot of analyzing that needs to be done first before the actual install.
The other thing that needs to be done is to simulate the load of the EGR & AFC so the CPU thinks they are still hooked up.

For more in depth info please see the ORM Circuit thread.

Yep the housing is included. It was the most pricy item on Tim's parts list.

I think I will pass. Not sure if I am up to the whole task. I don't want to hose the basic wiring system. For now I will stick with the ORM and perhaps add the Scan Gauge. Thanks for the effort though.
