2) My second point is still stands, I would much rather buy a Calum or Nistune ECCS setup than an EMS & et all. Hell, I would rather convert to the U12 Stanza ecu and use an emulator for realtime.

The Microcontroller is a POS.

8 Bit? 4mhz? NO A/D input?

Atmel?

28 PIN DIP? Kill me now.

The maxim chip is a crutch for the POS Atmel.

Could have build the whole thing without dips and through-hole garbage for $8 a piece at a board house, have it 1/10th the size using qfp devices. The use of this garbage can type diy build is what makes it reminicent of the 70's or 80's era equipment. The only thing that brings this close to the future is the use of an led 7seg and VW/Bosch's 4 wire.


As for the quoted sample rate, thats a bunch of garbage, thats how many times the firmware would "like" to take a sample. Its maximum REAL sample rate will be much much less (obviously).

Is this ROHS compliant? Or are we killing ourselves and poisoning our ground water with this?

The thread has been trashed. Buy this because you like tinkering. Don't buy it because you are low $, if you are not tech smart and don't have the money, work more and buy lm-1,plx, or NGK and save your time.

Remember Time = Money too.

If I remember correctly those 28PIN Atmel use to be in the old school 8 bit nintendo cartridges. I use to see chips that were labeled Atmel on them.
I bet you these chips have been stored in a dry fridge for like 20 years or so because these chips couldn't be properly disposed of.

Just ran across this thread, any updates on people's uses with this? Does this replace the o2 completely like the lc1? Or .. is it an additional o2 and still needs the stock o2?

Does it work with nistune?

I do not believe it has a narrowband output - that's what you need to replace the stock 02 sensor... but you don't want to put your wideband in the stock location anyway, so you shouldn't have a problem having your OEM sensor plugged in.

It should work just as well as any other wideband for Nistune, since it uses the standard 5V output.

I've always heard good things about the jaw , i guess for the price its better then nothing

[xs240]

Oh okay, well my o2 is actually at the downpipe. I have a 4-2-1 header which replaces regular manifold and downpipe. The o2 is right before the cat at the downpipe end, so thats not bad i think. Correct me if I'm wrong say yay or nay heh

i've been using this for almost a year now. no problems. my car runs great, and the jaw has been really helpful. i bought the jaw from the OP.
