Kpro usb and can output errors

[eprods2000]

Ap1 kpro mod with an aim mxs Data logger. Everything was working ok however after the last engine swap on the e production SCCA car I have some weird happenings.

1) map reads 29.9 on both kmanager and aim dash (can out)
2) ect reads 32degf on both kamanager and dash
3) iat reads 32degf in both kmanager usb and dash
4) no rpm readout in both kmanager and dash
5) all reporting normally when I use the Bluetooth to the phone


Any ideas?

And I couldn’t figure out my old account.

Sounds like it is not datalogging at all. What KPro do you have, what are the lights on the KPro doing and does KManager show with the ignition on?

I'll also shortcut to the most common problem on the S2000 which is forgetting to attach the harness ground on the end of the cylinder head, almost under the windshield.

[eprods2000]

Kpro4 running kmanager 4.4.2.

With ignition on it shows the same 29.9 32 32 and No rpm readout in kmanager or on the dash.

All grounds are in place including the one on the cylinder head in the back as well as the secondary from the valve cover to the chassis.

Lights in the kpro are all green. There is a red light at the usb when uploading Ecu program.

What is the serial number that is on the K-Pro board?

[eprods2000]

serial number is 43715

software version 4.4.2.0
boot firmware version 2
main firmware version 14

outputting CAn to AIM MXS vserion 01.28.10 it's not an aim problem as even with the USB cable in Kmanager i get the same readings that the mxs is showing. still getting full readouts outs from the app on my iphone without any issues

Disconnect everything from the analog and digital inputs and see if the problem persists.

[eprods2000]

I’m not using any inputs to the kpro. I’m only using the can out to the dash.

[Spunkster]

Yes, disconnect that.
