Hi all
I installed S2Pro1 cams and got used hondata S300 on P28 OBD2B ECM
took it to the friend of my to tune it spent few hours on the dyno and everything went well to the point when we went for road test. Few minuts on the road and car starts sputtering (A/F was going to 10.0 at that moments) then CEL came on and car went to limp mode(2000rpm and rich) we put laptop to it and it gave 3 codes: IAT, TPS and CTS got them reset star the car up let it idle for like 2min and same thing limp mode with same 3 codes. put it on the live data and looked for those sensors: colant temp was jumping from 150to205 and was offline few times, IAT looked steady, TPS looked steady to the point to the point when it goes to limp than it stays locked at 25%opened ones it jumped to like 108% and car stall
And i never had this problem with my old ECU(had a PCT)
Is it bad P28 or i have to look at something else ???
Thanks for any replay
