I have a mugen spec chipped P28 ecu and has been Programed to run DOCH vtec Motors(b16,b18c,ls/vtec) and single cam vtec . I had bought it for an ls/vtec project but is now turbo charged. The ecu Has a removable socket installed if you want to change the chip in the future. This ecu will work on any grey plug wiring (92-95 honda/acura OBD1). The fuel maps and timing are advanced. Vtec kicks in at 5700 rpm and pulls all they way to 9,000. This is a great ecu for people doing a motor swap and is missing an ecu or for just upgrading there stock ecu. Let me know if your interested and if you want to see some pics. Thanks
