OBD2 HandHeld Tuner Interest Thread

Well with all the fuss about JB4, I thought I would create this thread as well. Partially for kicks, and partially to get conversation going about an OBD hand held tuner for us so we dont have to send ECU in.

I have been playing with star diag system through OBD and have adjusted my vmax to 250kmh or 155mph without a tune. It requires a special seed key to gain access to these parameters that i retrieved from a source not to be named at this time. if you are active with coding stuff i am sure you could find it.

anyway, with this sort of access, adjusting the tunable parameters is just as simple. I dont know how to tune well, as i have no experience, but just throwing this out there to start a convo.

Anyway, my question is, if these tuners really know what they are doing and not just copying tunes from overseas, does anyone have an OBD2 coder in development yet? As a business owner myself, I know its one thing to make a bench prototype or one for yourself and another to mass produce. But I know at this point its possible.

so when are we gunna see it?! this would help to eliminate suspicion at dealerships (in or out of warranty) as well when they dont see the ecu seal cracked open. I would also feel better not having someone open up my ecu.

Thats awesome man.

i know there’s skepticism if any of these tuners are tuners, but I can confirm EC Canada aren’t buying canned tunes and reselling them.

You should contact one of the full ecu tuners for our platform and get this going!

im leaning towards eurocharged at this point for price and performance. They also had a handheld for the w204 c63 so i bet they should be able to crack the w205.


but i am trying to enjoy the car in stock form as long as possible, because once you tune you dont go back lol. my buddy just boot mod tuned his 435 and he says its a monster. (he has the usual bolt ons), blows his jb4 he had out of the water. he is actually a good source for me as i was debating the piggy back route vs full tune. He said the full tune helps so much as all the parameters are adjusted and expecting the extra power. He is very impressed with his throttle response now. So for me this has convinced me of the full tune as well. it makes sense though as well that all parameters should be adjusted to expect the new input values.

Yah, totally. But don't underestimate the JB1/JB4.. it's still a good product. But if you want the best performance you can get, you're right, its not the JB. I think this is why most BMW guys get a full flash tune, and throw a JB4 on top for boost control.
