Car is a 99 Civic LX.


Ok so Not sure how to go about this. I have a GSR motor but b16 ecu. Already have a JG Victor X Manifold on it so will the b16 ecu work? or should i get a OBD2B to OBD2A Jumper and use the GSR ECU. Or should I use the b16 ECU for emission and run a OBD2 to OBD1 jumper and use an OBD1 p72?


Update: Issue is. 2000 GSR ECU has immobilizer. dont have the key chip or the key ring.

 

Use the Ecu that was intended for the block.

 

No reason why? isnt the main reason to use the p72 is for the secondary butterfly? but with the JG IM that doesnt really matter anymore right?

 

eventually you will want to have it tuned. go to phearable.net and get an obd2b to obd1 jumper and a chipped p28. my em1 with gsr swap pulled hard with the p2t ecu, but i wanted it tuned so i got the p28

 

OK yea that was the route i was planning on going. Do you use your p2t for smog? or do you not have emission control where you are?

 

where i live we don't have smog inspection.

 

you should use a gsr ecu just because you are using a gsr engine. if anything your gsr will underperform with the p30

 

what about a chipped p28? only thing i need to pass is smog once a year which i think i can do with the b16 p2t.

 

yes a chipped p28 will work well with the gsr

 

perfect. thats the plan now. Chipped p28 but the oem gsr ecu for smog. Found a bypass for the immobilizer

 

Get your ecu chipped and flashed with a gsr base-map. The b16 with its smaller displacement has a leaner fuel map because it needs less fuel than a gsr. If you run a b16 base-map on a gsr, you could potentially lean the engine out and burn it up.

 

Or buy the obd2 aem series 1 ecu im selling for 750 obo

 

Thanks but still wont pass smog and chipped p28 is cheaper

 

How would it not pass wide band and keep it 14.7 it would but yeah it is cheaper but im willing to drop price well if u know anyone hit me up

 

doesnt the obd2 port not work when this is plugged in instead of the ecu?

 

I believe it still does
