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.
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.

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

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...

It runs
Added coolant after making sure it ran and wouldn’t eject belts.
Will need to bleed coolant and finish bleeding the power steering
Bleed brakes as well, clutch was fine
There’s tons of loud valve train noise, going to assume it’s because of a completely fresh vanos and completely refreshed head, as in, need to bleed the lifters and get oil into everything. Same thing happened when I originally put the s50 and started it (albeit this time around is much louder, probably because I never removed the head last time-who knows).
Basically now it’s bleed coolant, bleed/flush power steering, finish up the gauge panel and figure out why the hell my e30 temp gauge immediately pegs red hot when you turn the key on. Going to try and swap the temp sensors as I do not remember which one goes where
Hopefully worst case scenario is I have a bad temp sensor (unlikely as they are new)
-
Oh also I need to go to an exhaust shop eventually, these headers won’t work with the mid pipe I have which is super convenient
-
Woohoo! That must have felt good!
For temp sensors, make sure the connector with only one contact in it is on the brown temp sensor (or single pin, they are sometimes clear).
I'm stoked to see more of this!
-
Rattling is normal after sitting for a long time. Hold the rpms around 3k for a little while and it will pump the lifters back up. Almost ready for burnouts/axle breakage!
For sure!
Different angle
-
yes, i demand many burnouts and axle breakage ! A lot of 'yes' right here. Love the sound of the motor firing up

They both have 2 contacts

Swapped connectors. Gauge doesn’t jump full hot when I turn the key on now. Should be good.
FYI, both e36 obd1 harnesses I have indeed are two pin connections for the temp sensors. Only 1 pin sensor I can find that is close (distance wise) would be for the oil pressure switch.
(Manifold temp sensor may also be 1 pin as well - but I ruled this out because the length of the harness is a dead give away to where it connects to)
-
Awesome! I can't wait for a ride!

Awesome that this thing is so close!
I know that the way I have my car set up is one connection is for the gauge, the other is for the ecu readout, and if you flip them, the guage would pin itself. Same with my E24, but that has one single pin, and a double pin. I have had the luxury of finding this out with both cars. lol

Bleeding coolant tonight, also will try and get the head “bled” tonight as well at the same time, it was loud on startup

Rumor has it that burnouts (with videos) actually clear this up the quickest.

First and last drive of 2017 happened today.
Until next spring!

Well, MS3 Pro is on the way.
Never really liked the idea of the chiptune and no datalogging capability.
Thankfully the turbo Miata has been a good learning experience

I have spent a few hours already looking at piggybacks, emulators, and logging systems for OBD1. There just isnt a proper tuning solution that doesn’t involve guess and check.
Nothing will run a stock-ish engine better than a stock DME, but a completely different EMS like megasquirt is really the only solution if you want it dialed in 100%
Logs are awesome
