I have running the P28 chipped ECU on a JDM Accord CF4 Sirt (OBD2B) and I have bought the basemap chips from phearable.net recently. When I try the new chips on yesterday, the CEL was ON during startup.... will it be the problem due to VTEC pressure switch not exist on the JDM Motor?

I know there is a ways to bypass using the trick "skywire" (A4 to D6).....but I dunno which location I can do such .....as I'm using the OBD2B-OBD1 conversion hardness.....

can anyone give me some hints?

 

 

can I add the "skywire" on the OBD2B-OBD1 conversion harness?

 

can I add the "skywire" on the OBD2B-OBD1 conversion harness?

 

Yes, if you don't have a vtec pressure switch and you are throwing a code 22.

 

Thanks !!

 

I have fixed the issue on the CEL#22 on by adding the skyline between A4 and D6...
However, when VTEC kick-in....seems that the VTEC is ON and OFF for between the 5000-5300 rpm......any hints on that? no CEL was throw this time....

 

Check your oil levels. If you are throwing no codes & vtec is intermittently working, the issue is usually mechanical

 

so sad about the chips due to poor gas mileage......only around 6km / Litre......
I really dunno what can I do......

Any help!?

 

Poor mpg is not normal with a simple application such as yours when using a basemap chip.

Do you have a wideband oxygen sensor gauge ?

 

I don't have the wideband o2 sensor gauge.....
