Re: Hello from Spain!

I believe your tuned fuel table typically compensates for this kind of issue as well as the table compensates for many other issues. I suspect you will not see much of a performance difference on a table driver design. If we get around to doing model based calculations instead of table based calcula...

Re: Frankenso - ECU shield compatible with OEM case / official

China assembly is key. The connector cards is difficult with China assembly. I once dreamed we would make wire boards to simplify the different PNP setups with that connector. If you don't have the frankenso connector you probably do not have the same case in the same location. If you don't locate i...

Re: Frankenso - ECU shield compatible with OEM case / official

Did you install W23? W23 is used to verify the 5V is working properly before you connect the 5V stuff to it. AKA if you get a cold solder joint on one pad which needs allot of heat to make a good connection, you would get 12V on the 5V line. This W23 allows verification of the 5V before accidentally...

Re: let's choose an enclosure

Do you plan for this to be IP67 or similar? I wonder about the water resistance of the USB. As well if they are surface machining a mold, perhaps adding an o-ring groove could make for a nice water resistance feature.

I like the entire you don't see bolts thing. That makes it look clean.

Not likely to be hot heat. The chips can handle allot of heat. Generally your PCB will fail long before heat damages the chunk of glass.

Re: electronic throttle body control ETB

With out other stuff, can you open and close the ETB fully? I wonder if the higher amps at WOT are causing a ground to pull up and for the command bits to get lost as they might not generate enough voltage.
