How do you measure IQ?

[starrd]

On the "TDI" the third injector has a sensor built into it.

So how would we measure the IQ on TD engine? Any injector mod? or using TDI injector?

Hey,

   on instructables there is a DIY for turning a laserjet printer into a PC board printer. It would save you the cost on caustic chemicals and all those wonderful smells associated with making your own boards.

you are still required to etch the board. They use ferric chloride, as listed on the front page.

easily in the top 5 most amazing and impressive threads i've seen on not only this forum but all of the internets.
hats off to you dude.

Honestly I have never made my own board, and didn't really read it. I just saw it on my instructables email and thought it would be right up Hey's alley.

Excellent work,  

Could I possibly get the schematic file of the TD circuit? I use ARES and ISIS as my design package but have access to others.

I would like to modify the circuit slightly for different sampling and control with maybe a tacho driver as well.

I have access to a PIC devolopment system but have no experience of HEX code, can you give me an idea of how your program works? does it contain a simple map?

Thank you.

Hi,

I've roughed out a basic schematic for a TD controller, am hoping to drive a tacho but with bargraph for VNT position and a digital boost display.

I've downloaded MPLAB and disassembled your code (to no avail) I'm not intending to market anything, and any developments made on a TD version will be documented and freely distributed on this site and others. Any help you can offer regards reverse engineering would be excellent.

Yes Badboy - I'll make you one too!

how about an Arduino based controller?


I've just learned of this PIC replacement, and it's an all-in-one kit, I bet we could make it so no PCB's would have to be etched!

An Arduino should more than do the trick. It might be considered overkill, but could also add some very interesting possible features, like a display and laptop connectivity. Change up your software, upload it via laptop and 'reboot' the car and you'd be ready to go. The dev environment is also really easy and that community is huge. Probably lots of help. Not that i've done more than blink a couple LED's with one but it would be a great alternative to a custom built board and offer loads of flexibility.

That said, what Hey is doing is REALLY COOL! I'm very excited about it.

A glass to have the acetate match the board perfectly. VERY higly IMPORTANT.

Some idi engines had an injector measuring injector lift;

eg Peugeot 406 turbo diesel.

Has anyone built one of these recently?

Thanks for sharing.   I might have to give this a try later in the summer.  I wonder if a circuit can be drawn
with this conductive paint stuff.

Im surprised somebody smart doesn't sell kits for these turbos for dummies like me that just want to buy the parts, follow the directions and install.  Because I don't understand the techie stuff

This is the reason I only have stock junk on my 1.6td, would love to buy a kit to install, then take it down to the exhaust shop to have a custom fit kit made.  I hate the t3 turbo in my car

Kinda where I am too.  I could figure it out with the help of a few people I know, but I'm just not that motivated.
I would however spend money on a pre-figured solution.  I'm sure it'll happen eventually.
