New to tuning/ECMLINK does not show accurate RPM

[Dsm96GSX]

Hello all been a DSM owner for awhile. Recently lost my tune on ECMLINK V3, which I don't know how happened but oh well, anyways Iv taken matters into my own hands and attempted to tune the car myself. My main issue right now is that my RPM gauge and the RPM shown in ECMLINK do not match. Is there a setting I need to change in order to adjust that?
Thanks

Hmm, could you post a log?

Is this what you mean by a log?
It shows 1100 rpm but my gauge is at 400.

Power transistor could be causing your issue.
it could be the actual tach gauge.
Either way they are connected and its far less likely your ECU is lying.
You should already have this concept.

Does it feel like its at .4K or 1.1K ?
I will guess it feels like 1.1K so you have the concept.

The car feels like its at .4k at idle, it feels like its just barely running. Would that still point to the power transistor/ignition module to be the culprit? So far I have read that the ecu gets its rpm reading from the ignition module/power transistor but would a faulty one cause it to read double the rpm?

Yes double triple half none.
Like i said it could be you actual cluster.

Sounds like you need to first get your actual idle in line .

Before moving forward. Some clusters dont show that low anyway.
A constant speed test will probably seem more accurate since so far it appears your accounting for idle.

So today I replaced the Power Transistor/Ignition Module and it has not had any impact on RPM. Also its unlikely that my cluster is faulty, prior to this situation about two months ago when car was running fine the tachometer functioned perfectly.
