Hey kids, I need some help connecting my laptop to my EMS stinger ECU.

The EMS uses a serial (DB9) port to connect to a laptop, and my new laptop only has USB ports.

I've purchased an adapter, but I've been told that it's the problem.

Does anyone know of a different method to connect to the laptop or another USB -> serial adapter that works?

Thanks.

The expensive Belkin adaptors work very well. The cheaper USB->DB9 adaptors use a cheap RS232 chip that causes these sorts of problems.

yeah i thought so too... i bought a $99 one and it doesnt work :(

Best ones are the datalogit(smoked black) one or the wolf one (white blue leds on sides).... different ecus like different adapters... its a real pain.

Its one of the reasons i use a toughbook as the serial is rock solid and i no longer have to use usb-->serial converters....

Yeah I've found one made by IOgear in the states that's $55 from an Australian website.

Does anyone know how to set it up on the laptop?

i.e. selecting which com port to use on the software and which USB port related to which com port.

Trent, do you have any experience with the EMS stinger software?

when the usb dongle is working it will just appear as a COM port in windows

ie you dont map a serial com port to a USB com port

your laptop should have zero com ports, then when you install the USB dongle, a new COM port should appear

you choose this in datalogit or the software etc

as a last resort either a toughbook with true serial ports or go for dell 2nd hand ebay junker laptops

usually have working serial ports and cheap as chips

yeah we do quite a few make sure its not an early version 3 that cant rescale the load points.... real evil little fckrs. The motorsport stuff is real nice to work with.

i have a couple of different adaptors here including the datalogit one if you wanna try them before buying one.

That's a real good idea mate thanks, I might have to take you up on that offer... I'll PM you later

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
