ok 1992 civic hatcback with a 98 ls swap b18b and b16 tranny just got it running good and just running a obd1 gsr ecu p72 and i do plan on doing ls vtec in the near future maybe a few month what would be the best ecu to get and chip for obd1 i have heard p28 obd1 is the best to chip is this my best choice any help or info is appreciated guys thanks a lot

 

ur best choice would be to chip a p28...a p72 is meant for a gsr because it has secondaries and running that on a ls will not give you the performance you want
