Berry tuning tool

[rolls]

Anyone serious about writing a tool wouldn't use a ELM327 either due to the restrictions they have. I'm sceptical this will turn into anything.

Does a working prototype exist? I hope so otherwise pledging $40k is crazy.

It seems all talk at this stage but I'd like to be proven wrong.

Looks like its just a standard arduino.. but has the ELM command scheme implemented. Theres free arduino ELM projects available on the web so I wouldnt be surprised if he's simply based it off of that... and then also added in his "special" side of it.

So it does simulate senor input. Assuming this thing is even real with a real life prototype that actually works on more than one model car, Im thinking ECU's might from factory search for standardized CAN bus messages from modules that might not even exist... sort of like a plug'n'play upgrade system. One vehicle might pass live sensor data through a middle man device onto the ECU.. this could be all standardized into all OBD2 compliant vehicles.. meaning even our Holdens without that module will still actually accept the same frames?

Just makes me wonder what takes priority then.. the hardwire connection or the CANbus message. Would have imagined there would be alot of conflicting messages occurring then.

That then leads to.. if a car already has a module output that specific CAN ID to display that live data, then would that live data conflict with the berry.. or does the berry search for that message and immediately send out its modified message?

Possibly the last and most valid theory I can possibly think of...

Wish I knew someone that committed to a module.. would love to get a log of what its doing... or just simulate data to it and log its unique responses.

Afaik everything important is hard wired, knock sensors, injectors, intake temperature etc. The PCM does echo these values out as PIDs etc (so the dash, abs etc work) but if you were to mirror them it isn't going to change the actual PCMs behaviour.

You can do some cool stuff but no idea how you could do anything to change the vehicles performance as this is a closed system that you can't interact with. Not to mention every vehicle is different, often extremely so. You could fake data coming out of the PCM but all the input sensors are wired direct to multiplexed A/D on the PCM, you can't change these without actually intercepting the signal itself. If you are going to this then there are better ways, eg our traditional flash retuning which of course is extremely specialised per vehicle.

I just can't see how it is possible to achieve what he is saying without reflashing the PCM to a completely custom OS, and if that was the case then I would expect it to be $40k per vehicle in R&D costs if not more.

edit: This must be tested on cars that allow writes done on the fly, that means they must have maps or definitions for all OS they support. I'm very sceptical.

also this:

We did begin testing on emissions, though accurate data could not be gathered and matched with manufacturers certificates. We decided against the practice and cannot guarantee any changes to emissions. As a general rule, Air/Fuel ratios are improved by Berry thus theoretically lowering emissions.

Leaning a car out increases NOx compounds, hence emissions are more toxic. I guarantee they are in fact making them worse not better.

Couldnt agree more.

I just sent him a series of questions, be very interested to hear the reply.

I imagine he would have sent the exact same spiel about "Kickstarter allows its users to get an indepth understanding.. blah blah blah.. we canno go into details as it will comprise the devices architecture".

3mins aye.. what could it possibly be doing..

Can mode 4 be entered at all times. Some manufacturers block certain modes in certain situations. I rember reading that Nissan block some modes based on vehicle speed. If the developer has the skills to cover all those vehicles and the various units he has some real talent.

What is can mode 4 ?
