i have the above in a mx5 and it wont get any power unless connected to my laptop - doesn't even have to be connected to tuner studio.
i asked the question on FB and lots of comments re dud voltage regulator and "LM7805". im looking at the ECU and i cant find LM7805 no matter how hard i squint! any help with locating it?
i note there is away to bypass it. is there anything else i should look at first? my soldering skills are very bad so id happily pay someone to do it for me if anyone is keen!
