TopDawg_43 Posted January 27, 2003 Report Share Posted January 27, 2003 When I install my stand alone, do I have to keep the factory ECU?? Â And do all the factory gauges still work? Â Like the boost gauge and tachometer, will they still work? Link to comment Share on other sites More sharing options...
Quest4Power Posted January 27, 2003 Report Share Posted January 27, 2003 you will need to keep the factory ECU to run the gauges if you want them to work (other than the Speedo/voltage/fuel level). all the guages on the right side of the gauge use the ECU signal. i scrapped mine in favor of all new autometer gauges.

chiplee Posted January 30, 2003 Report Share Posted January 30, 2003 yes, anything that changes airflow will require adjustments. Link to comment Share on other sites More sharing options...
DJpowerHaus Posted January 31, 2003 Report Share Posted January 31, 2003 The Tacometer doesnt work with a standalone system? Tell me if Im wrong: Works..........Doesnt Speedo.............Tac Voltage.............Boost (did it ever) Fuel Level..........Temp ..........................Oil Pressure What about warning lights? Brake warning Light Low Oil Light Low Fuel Warning Light Engine warning light ABS Security... what am I forgetting? Link to comment Share on other sites More sharing options...
chiplee Posted January 31, 2003 Report Share Posted January 31, 2003 all the guages work. You'll have to tap threads for the guage coolant temp sensor and screw it in somewhere but other than that, the oil pressure guage will work and the tach may act a little screwy sometimes but it should work. I think all the warning lights work too. I left the factory ecu inplace because I didn't know what all was making use of it other than the engine. It's a pretty simple test to unplug it and see if anything changes. I'll try to do that this weekend. If everything were to stay the same I'd go ahead and pull the factory ecu and harness, but I suspect some of the functions of the ecu would be missed. We'll see.

DJpowerHaus Posted February 5, 2003 Report Share Posted February 5, 2003 I cant wait to see the results. Selling an 88 ECU will go nicely towards financing my home brewed MPI Link to comment Share on other sites More sharing options...
chiplee Posted February 5, 2003 Report Share Posted February 5, 2003 glad you replied.. I couldn't remember where I said I'd post the results of unpluging the ecu. I did it, and I lost nothing. Car obviously runs the same, and all guages function normally. Mine is already sold. Link to comment Share on other sites More sharing options...
