Re: S14a SR20DET bucking at cruisung

Hi Pinto, Does your SR have aftermarket cams ? (not 100% cause by the cams, but symptom exaggerated after aftermarket cams installed). I own my SR for 2 years now, since I change to 256 cams, it start to jerk (feels like engine pushing and pulling, bouncing back and forth ) at very low rpm, it jerk ...

Not the software freeze, only the wideband numbers freeze.

Re: AEM Digital Wideband UEGO Gauge with DLP-IO8

First I've heard of this issue 1. Does this happen since a particular version? 2. Can you enable debug logging 3. Does it freeze up when running the car, or even at idle or with ignition key on only? What is the frequency of the freezeups (time between freeze?) I do not know, since this is the firs...

On the other hand, the AEM wideband fail s...

Re: AEM Digital Wideband UEGO Gauge with DLP-IO8

Yes , if using AEM UEGO default P00 or P01 Voltage/AFR output table. The table is from AEM installation instruction pdf. The DLP to nistune will slightly off. eg . AEM default 2.000V = AFR14 but I need to shift to next voltage 2.125V in order do display AFR14, still 0.1 point off the gauge. PS. I ha...

Re: AEM Digital Wideband UEGO Gauge with DLP-IO8

The DLP setup is grounded to AEM power source ground, all channel in nistune is more stable, but the AFR still 0.5 point off, I can set up a CSV to match it. I also set up the aem serial output to my notebook, but I can't get it work. Is here any instruction how to configure nistune to accept the se...

Re: AEM Digital Wideband UEGO Gauge with DLP-IO8

I have just read the NIStune Software Users Manual V2.0
I can use the serial output from the UEGO gauge and no look up files (CSV) need.
Will this serial output display real AFR in nistune ?
