I'm going the route of UBERDATA with my OBD1 PR3 J (yes the rare ecu). I want to be able to put the stock chip back in for emissions testing and what not. Can it be slid into the aftermarket socket and run with no probelms? The reason I ask is because you have to solder other wires and resistors into the system - I'm not
sure if that messes with the stock chip/tune at all. Thanks!!

 

You don't have to solder anything if it already has a chip.. just desolder the chip and put in a socket and put whatever chip in you want.

Wow, I love honda-tech misinformation, it's not your car so it doesn't matter what you tell the guy on the other end as long as you get a post in.

Alright now for the truth, if you want to run the chip that the ECU was originally all you have to do is disconnect the jumper at position J1. You will have to reconnect this jumper by soldering when you want to use an external chip again. If you have access to a chip burner you can burn a stock chip that can be found on the internet and just drop it in. The additional parts you are soldering into the ECU are so that you can properly run a second chip (Your socket).

Right back at you bud. You do know that some ecus, came with stock chips correct? And they actually run off the external rom. Next time research a little. You can do DSMs the same way. I wouldn't know, I have only chipped about 200 ecus.

SO I will break it down perfectly for you. If your ecu came with a stock chip, you can tell because it will be in the 28-pin chip already in the lower left hand corner, and already have all the components that you would have needed to put in for another aftermarket chip. Such ecus as the PR4 and PR3 came with stock chips in those locations and also automatic ecus did (very rare though)

So if you have a chip in there already, all you do is desolder that chip and put in a socket. Then you can put any chip that is designed for that particular ecu including the stock chip. But if you do not have a chip in there, follow the man above this posts information. Which will actually put you right back to stock, just by cutting the jumper at J1, a switch can also be installed.

Hope that cleared some stuff up.

He was calling you on that statement.

 

That is the only thing he talked about solder in there. I was refering to the resistors, they are already there. I said you had to desolder the chip and solder in a socket. but nothing more.


You should really post the whole quote.. makes sense when you read the first part then read my statement.

 

as far as i know, i have a virgin OBD1 PR3.

I would like to clarify that if I run a uber socket/chip package.. the jumper wire AND other misc parts (resistors) will be installed. Its been made clear that the jumper wire will need to be cut to put the stock chip in the new socket... but what about the other misc parts(that weren't originally there with the stock chip)?

They dont effect running the car on the stock chip.

Once you cut the jumper, it no longer flows any current through those parts. So they can be left.

 

Thanks guys!

93turbob16.... what kind of uber tuning can you provide in the OH area?

 

I offer dyno tuning in south central PA. ALso full street tunes. you just have to get to me.

 

ok i ripped it open and checked it out. THere IS a stock chip in there. I looked at the other components. The UBER kit from moates came with .104 Caps and the ones in the ECU are .103. Where the Jumper wire should be, is a resistor-Looking wire with ONLY 1 black stripe (possibly a type of jumper?!). I just want to make sure those pieces will work. The 1k Resistor is fine. tHanks

 

The 104 capacitors are the ones you want, those are the 0.1 uF that you need. The resistor looking thing is a resistor with a value of 0 ohms, so just a jumper. Honda uses them in other parts of the ecu, if you look around you'll see them.
