mikey4410 Posted May 19, 2014 Share Posted May 19, 2014 I have noticed my fueling is at 13.5 afr when idle instead of 14.8.My normal inlet temps are 20 degrees.with this hot weather im getting 45 degrees inlet temps I am guessing the ecus richening as to stop detonation becausenof heat ? Is this right ?Just wanted to check Quote Link to post Share on other sites
GP82 Posted May 19, 2014 Share Posted May 19, 2014 It corrects off speed density, but not at idle. This will be closed loop operation. Check your 02 sensor and wiring, but seem's like maybe you got a leak somewhere or restricted airflow? Quote Link to post Share on other sites
richardc9052 Posted May 19, 2014 Share Posted May 19, 2014 It must be your lambda or a leak before it causing it to read incorrectly.. If your using an AEM UEGO wideband you can change it to PO4 on the switch at read and splice the white wire into the lambda input on the ecu to give he reading from the widebands 0-1v emulation. Thats how mine is now and it works great Quote Link to post Share on other sites
mikey4410 Posted May 19, 2014 Author Share Posted May 19, 2014 The driving afr is different also.around 13.5.So its defo not right even at driving afrs of 13.5 and 45 degree inlet temps ? Quote Link to post Share on other sites
mikey4410 Posted May 19, 2014 Author Share Posted May 19, 2014 Okies so I I had a fiddle about with the lamda and not made a difference at all.so u guys reckon a new lamda wud be in order ? Quote Link to post Share on other sites
mikey4410 Posted May 19, 2014 Author Share Posted May 19, 2014 Also Is there anything else it cud be.The only thing thats changed is the other day I had all the turbo of . Quote Link to post Share on other sites
5e colin Posted May 19, 2014 Share Posted May 19, 2014 as the guys mentioned a air leak before the sensor or sensor on its way out ????? Quote Link to post Share on other sites
mikey4410 Posted May 19, 2014 Author Share Posted May 19, 2014 I did blast the current lambda out with brake cleaner but I didnt think that would damage it at all ? Quote Link to post Share on other sites
mikey4410 Posted May 20, 2014 Author Share Posted May 20, 2014 Update !!!!Cars sorted.thanks for you guys help.did what somebody suggested and ran a feed of off my innovate wideband brown wire to the lambda plug and instantly went from 13.0 afr to 14.9 afr.Obviously the lambdas dead but will just wire a hard wired form innovate permanently as its a bosch sensor and decent qualitysuperb wicked result.thanks alot guys Quote Link to post Share on other sites
5e colin Posted May 20, 2014 Share Posted May 20, 2014 so the sensor is dodgy but works wen wired to the emanage blue ??? Quote Link to post Share on other sites
mikey4410 Posted May 20, 2014 Author Share Posted May 20, 2014 The stock lambda is fucked for whatever reason and reads totally wrong.I wired in the innovate wideband analog feed to the stock ecu and its bang on now.I dont have e manage Quote Link to post Share on other sites
EP-Azz Posted May 20, 2014 Share Posted May 20, 2014 Mine also has this problem ?? Really low on idle around 12.2-13 but on wot I see inbetween 10.8 and 11.6s and cruise is 14.7? Would you suggest same thing Quote Link to post Share on other sites
mikey4410 Posted May 20, 2014 Author Share Posted May 20, 2014 Idle and cruise at warm should be 14.8. 100% Quote Link to post Share on other sites
EP-Azz Posted May 20, 2014 Share Posted May 20, 2014 Cruise is fine idle is way out !! Help ? Quote Link to post Share on other sites
5e colin Posted May 20, 2014 Share Posted May 20, 2014 The stock lambda is fucked for whatever reason and reads totally wrong.I wired in the innovate wideband analog feed to the stock ecu and its bang on now.I dont have e manage ha now i get it ooops the wideband replaces the stock feed to the stock ecu nice 1 ecu will be getting a much better controlled signal faster to richard u clever fecker :) Quote Link to post Share on other sites
EP-Azz Posted May 20, 2014 Share Posted May 20, 2014 So could you just unplug the std lambda because the wideband reads narrow band aswell doesn't it ? Quote Link to post Share on other sites
mikey4410 Posted May 20, 2014 Author Share Posted May 20, 2014 Yeah unplug standard lambda and run an analog feed from wide band . done Quote Link to post Share on other sites
5e colin Posted May 20, 2014 Share Posted May 20, 2014 will this work with the aem 1 to ???? or only the inovativ 1 Quote Link to post Share on other sites
karl. Posted May 20, 2014 Share Posted May 20, 2014 will this work with the aem 1 to ???? or only the inovativ 1 Colin have a look It must be your lambda or a leak before it causing it to read incorrectly..

richardc9052 Posted May 20, 2014 Share Posted May 20, 2014 No probs The 4efe ecu idles waaay leaner Its at 14.5-14.9 on very light cruise and then 12-13 on full throttle depending on rpm Quote Link to post Share on other sites
5e colin Posted May 20, 2014 Share Posted May 20, 2014 Colin have a look cheers carl :( Quote Link to post Share on other sites
EP-Azz Posted May 20, 2014 Share Posted May 20, 2014 12-13 is lean for WOT imo Quote Link to post Share on other sites
