New S200b in P72J ECU - inop! Advise?
Posted: Sat May 29, 2004 3:23 pm
Hello all.
After following Hondata's development for years (since they were in NZ), I finally got my own system. I have a JDM B18C from an Integra SiR-G, Jackson Racing Supercharger with Endyn stepper pulley, and the corresponding ECU for the engine (with the shorter ECU case and surface-mount technology - P72J).
I bought my S200b from Payn Tech and had them chip the ECU and provide their version of the JR "big boost" program. Installed RC440s and set everything else back to stock. Plugged in the computer and interface box - flashing red LED, solid Check Light, and car runs like an old muscle car with a lumpy cam (i.e. idles like crap! - obviously because the limp mode is expecting stock injectors).
I called Payn and they said to disconnect the J4 resistor. Tried that; no change. Tried holding the set button while starting, to reset the interface box: no change. Finally, re-installed the J4 resistor, removed the J1 jumper, re-installed the stock injectors, and bypassed the JRSC. Car runs as normal as it used to before the Hondata.
Payn says that there's a problem with the ECU because of the surface mount tech, but Hondata says that a P72J is fine to use.
Any advise? TIA
