Guys, I need the experts...2000 Honda Prelude Base, I swap my H22 for a H23A Vtec and I installed a JRSC, I'm running my OEM ECU P5M since is manual. the engine tested fine and I followed the instructions of the JRSC installation, finally I installed the JR EMS for prelude. the car starts BUT it runs hi, like 2000rpm, then it decides to run like is very getting fuel (I replace the Injectors with 750CC, Fuel Pump for a High Flow, Fuel Rail and Regulator for AEM), the engine light came on and it was 02 sensor heater, since I was using an AEM Wideband, I removed it and plug back my OEM )2 sensor, well the cel disappeared, but I'm still having the High RPM issue and is burning lot of fuel. I do not know what else to do, I don't hear any vacuum leak, checked all connection and recheck the connection from the JR EMS to the ECU. I do not know what else to do, need everyone advice, if I posted this in the wrong place, I'm sorry just let me know where it needs to be and I will do it.

tha p5m ecu may nnot work with the h23vtec; i knwo whenni got my h23 i told the guy that i didnt want the ecu as due to it being an auto ecu it has to be adapted to work. Also, a stock h22a4 ecu also wont work as it has teh incorrect fuel mapping. I think is this your issue man, as i know when you try and hook up the h23 to a normal h22a4 ecu that is abot what happens as well as rpm limitation of around 4600 rpm.

I think you would be best to buy a standalone and teh plug in the wideband and retune teh whole thing to run. If you like i can share the aem series2 tune that i have for my h23, but unless you have teh series two it will be useless.

What u mean by sharing ur aem? I was told that my oem ecu and the jrsc ems is tuned for stock injectors, so I was told to get a p28 mod specifically for my engine and all the mod are in the car

what i mean, is that i have a tune already made for my series2, a base map that i would share with you if you had the same unit. Now, if you are using a chipped p28 then the issue you are having is a simpel one, you need to retune it to run.

well ...my stock ecu and the JR EMS are tuned to run on a stock car with stock injectors, by upgrading the injectors to 750cc and the fuel rail and regulator, the stock ecu and ems dont know how to adjust to that, making it go higher RPM and burn fuel. I was told that by using a chipped p28 tuned to my mods and specs I will be able to correct all this issues. now I got this from a fellow member
