Re: Tuned my S14, Ignition map?!

And the timing under 4,000 rpm , on vacuum stage, it seems too much timing, What AFM ? different AFM will have different result on map walking. On which TP at mid rev range, your engine seeing 0...

Re: AFR very sensitive to electric load

Download the CSV and open it, you will see how far the AFR jump.
Earth point check twice with no resistant to battery ground (good connection), but found an interesting error on power supply, I think this cause the ECU to act strange behaviour. uploading video to youtube.

Re: Innovate SCG-1 nistune connected but no AFR showing in A

Problem solved, uninstall LogWorks and any related program, reinstall all latest version.
VB works and MTS can show up in Nistune.
Thanks Matt.

Re: Innovate SCG-1 nistune connected but no AFR showing in A

Here is the logs on the SCG-1
WB1 Connected, AFR window black screen, input tracer did not show any Innovate AFR for selection.
Same notebook, same DB9 to USB coversion cable, same version of nistune, it can connected to MTX-L on another S13 CA18DET 23710-36F00 Type 1 board ECU.

Innovate SCG-1 nistune connected but no AFR showing in AFR

SCG-1 can be connected to LM programmer, it also connected to nistune on WB1, but no AFR showing in the small window, just everything black out.
Could SCG-1 work with nistune ?
My MTX-L used to be work fine on eariler version of nistune, but does not work on lastest test release.
