Am I doing something wrong? Laptop connectivity

minivanman8 · Post by **minivanman8** » Tue Oct 15, 2013 7:51 pm

I have a Classic Mini running megajolt.

I can't get the megajolt to talk to my laptop.

I have bought a few new leads which came with drivers.....laptop says drivers installed fine, but when I open Megajolt configurator, I get no live data or on-screen runtime data.

Help before I rip it all out and go back to a distributor!!

Hello,

Hopefully this is an easy fix. You'll want to make sure the software is set to use the correct serial port that the USB->Serial adapter is assigned to by Windows.

This part of the Operation Guide should help: http://www.autosportlabs.net/MJLJ_V4_Op ... erial_Port

Let us know what you find out!

Com port is definitely the correct one. I've read and re read the operation guide in the hope that I've missed something, but I can't see anything

Thanks for the reply. Let's narrow this down:

- First of all, does the megajolt power on and can you verify it's controlling the engine's ignition advance? you can verify with a timing light that it's working on the default ignition map.

- what error message do you see at the bottom of the configuration app?

- do you have a different computer to try it on? maybe one with a built-in serial port?

- do you have a different usb-serial adapter you can try? Also, which one are you using?

- did you make your own cable or did you purchase the tuning cable along with the Megajolt?

Thanks,

Thank-you for the fast reply!

Timing does advance by a couple of degrees with a blip of the throttle. I didn't want to give it anything more than a blip as it's already blown a head gasket with the timing set as it is!

I have tried my Mum's laptop with the same results.

I have also used a few different USB-serial cables again with the same results.

I had to make a custom loom for the megajolt as the original that came with the van when i bought it had cables falling out of very poorly terminated crimps.

See screenshots below:

This was when trying to access global configurator options:

And the about screen:

I should add, my laptop is windows 7 and Mums is XP.

Anyone got any idea before I rip mega jolt out and buy a distributor again?
