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 ?

AEM Digital Wideband UEGO Gauge with DLP-IO8

Problems : Using AEM default analog output voltage vs AFR chart data, on DLP-IO8 to nistune, the AFR on nistune is around 0.5 point off to the gauge display. I have tried set up a new CSV to match the display, it only works for a while, turn off the car and restart later, my new CSV to nistune is 3 ...

Re: S14 SR20DET rich throttle / idle recovery

Although I'm still using factory 370cc injecors on my own car, But all of my customer's SR, usually change to 740cc injectors, it works fine on both S13 SR20DET early model and late model. Same method also works fine on CA18DET engine control with S14 early model ECU + GTR35 injectors. It sounds goo...

In the Throttle Enrichment, If target tune is for S14 ECU. Only 4 maps need to adjust. Copy the following maps data from S15 91F08 ecu Async MAF Factor Decel Loss MAF Scale down the following maps by injector size Async TPS Factor Async TPS Cut Factor Example for Async TPS Factor S15 91F08 ECU 107 8...

Re: S14 SR20DET rich throttle / idle recovery

I'm 100% sure it is throttle enrichment not tuning right with the 740cc injectors. I used to have same issue with 740cc, but now, I know how to tune right. Please note that I'm using standard ENT files, not Feature Pack base. Here is the result, transplant some of the maps from S15 91F08 ECU , scale...

Re: CA18DET deceleration issues

most of my tuned CA18 do the same, when let off throttle, not just R35 550cc injectos, AFR runs into rich to around 13s before going to 22, R32 444cc do the same thing, no matter how I try different setting, the off throttle fuel cut always delay a hair, what I thought is the injected fuel on the ru...
