Your heater core should be metal tubes. If so you can easily do what I did at the expense of $0. I removed the ends of the heater core from inside under the dash, and chopped them down about 1-2". this way the bend of the coolant hose happens right at the firewall vs. 2" out as shown in your last picture. Only downfall is that the hose clamps for the coolant lines are now under your dash rather than in the engine bay.

That’s a really good idea. But I won’t be doing that. Sounds like way more work than I want to do to be honest haha

curious to see what you do there. my spider hose exploded at that spot, the intake was touching and most likely wore a hole in the hose. i was considering modifying the rubber firewall grommet to allow pushing the hoses downward.

nice progress!

I’ll let you know what crap I come up with lol

[KaiserRolls]

Hopefully someone here knows.

The GIAC e36 chip was plugged into another GIAC board thing. Just curious as to what the board thing could be. The chip was originally for a 506 DME (my assumption based on the chicken scratch), but 413red and 506 can run the same chip.

Could this board be for an EWS delete?? Not sure if the 506 came with EWS or not though. Any info would be great. I’d love to just pop the chip into my 413 red label and call it good.

[B C]

You need it

The TRM tune for the 413 red label has it too so it doesnt have anything to do with EWS. Im guessing it completes or decrypts what is on the chip to protect the intellectual property.

Anyone can quickly and cheaply copy a chip and sell it for $300

But nobody really wants to replicate and produce the chip base too.

This is my theory at least

[GunMetalGrey]

Lightweight mod, take it out and see what happens?

I'd play it safe and leave it though.

[KaiserRolls]

Good calls.

I had never seen it before, but the theft portion makes sense

I mean, you wouldn’t steal a handbag right?

[KaiserRolls]

Snap cured my craziness. Chip is now installed.

[KaiserRolls]

So I finished this up last night & ran switched 12v to the distribution block. Tried to keep the wiring clean and manageable for future additions. Aaaaaaaaaand my battery is more dead than ever so I couldn’t test them.

Leaving it uninstalled until I can confirm the crap actually works. Then I’ll button it up.

+ adding battery to my list of things to buy.

Basically I need to do these to get it to run/drive:

Refinish the valve cover

Bleed stuff and add fluids

Hang exhaust/attach o2 sensors

New battery

It's a race to beat the snow!

[Jdesign]

Tis so close. What are you planning to do about music!?!

[jc43089]

The music comes out the back dude!

Those gauges look great! VDO vision? Do the gauges come with senders or do you order those separately? I'm going to be adding some to my car this winter too.

Correct VDO vision

Bought senders separately for correct thread pitch and to match the range of the gauge

Unless the handbag belonged to Bosch or BMW like the 90% of the code on the chip that they're trying to protect.

They take the stock code, tweek a few bytes here or there, slap their own "copyright" on it, and then get mad when you copy it.

I'd be really interested to see what would happen if a tuner tried to sue someone for stealing "their" intellectual property...

I'd be curious to mess around with it. You don't need to copy the board if you can get the unadulterated code and burn it to a normal chip. The ECU doesn't know anything about any of it, so I can't see how the chip and board together could read different than a normal chip...

..but yeah, most likely a copy-prevention device... carry on.

If I need music badly enough I’ll toss a Bluetooth speaker in the console or something

Just to be that guy.  What bytes do you change and how much?  Should they not make money for the R&D time that went into figuring out what and how much to change the stock tuning?  That being said, you are right, how do you enforce that with old technology like OBD1 chips?  It's pretty difficult to prove someone is copying your stuff unless you hide identification in the code that would not be there from another tuner.  Then is it really worth the legal costs to go after a copycat fraud?  Same problems as digital music and media copywriting.

Aren't modern OBD2 tunes VIN locked?  So it really isn't an issue any more.  I can't imagine there is much sales volume anymore in the OBD1 chip market.

[KaiserRolls]

Well went and bought a battery tonight, will try everything soon

[HipMF]

The stuff that they are changing are the lookup tables for fuel and timing. The chips contain both the tables and the the code that the cpu/microcontroller is running. The code is machine code which is difficult, but by no means impossible, to pick apart so that you can  actually understand what it's doing.

Ifa tuner only changes the tables without changing any of the code, it's easy to find exactly what they changed by comparing their file with the unmodified one. So to "protect" "your" code, you have to alter the machine code to obfuscate the changes you've made, say by finding the offset that tells the program where the tables are located, and moving them to a different location, or by doing some simple math on the values before they're used so that all of the values in memory look completely different than the unmodified tables.

Some of the tuners probably deserve to make a little money for the actual work that they've put in, but the business of selling tunes is by no means an honest one. Most of the people who've done the initial work are just hackers who do it for fun. It's easy for some less honest person to take the work that's already been done, make it difficult to reverse engineer, then call it their own and charge people $300 for it...
