HELP PLEASE!!! I have a Aem UGO Wideband that is currently setup on ANVolt 4 it is currently working but it reading only Lambda. I have all my settings to read AFR on both metric and Imperial but it still Reads Lambda/sensor Volt in my logs I have the Gauge setup per instructions and still no luck. Any help would be Great Thanks, Devin

Hey guys I have a weird situation here. When i enable the CLL function (auto mode wideband) at wot the target is 11.5 afr and the CLL is stuck at max clamp and the AFR is 10.8. Why isn't pulling the fuel back? I played with the gain features without any luck. I wired analog input from AEM Wideband gauge. Lambda avarage is reading lean.

Hi All, I realise that this is not really the place for getting help with the basics, but I am going to put my hand up anyway and see if there is any love. Newbie here and just finally got all of my sensors wired up and my ECU in my car. I am experiencing some very interesting AFR fluctuations during the initial setup and would like to request the input of some more seasoned individuals... First of all, the details: Evo 8MR GSC S2 Cams FIC 1050cc Injectors Stock fuel reg (presumed to be 43.5psi) Link G4+ Plugin Link CAN Lambda Sensor, Flex sensor Bosch IAT M&W CoP Kit AJD300 - Day 11 (enrich and overrun changes) 2.pclr Also a MAP EF2 turbo and bigger blah blah blah to support things. Not sure much else is relevant to the issue at hand as the car runs and goes like stink with the factory ecu (tuned with ecutek by a tuning shop on the GC so I cant get to any of the data) installed. I have been able to get the car started and get it idling, revving up, and some very minor back and fourth movement in gear so far. My problem is that under transitional throttle conditions, my AFR goes all over the place. Basically any increase in revs or load (yes even if load remains the same) results in extreme leaning quite linear to how quickly I depress the throttle. Also, if I let go of the throttle in any great hurry, it results in a RICH condition. I have been able to make my way through the rev range to about 3500rpm (while stationary ofc) while being incredibly gradual with it. So long as I increase the revs incredibly slow I dont get massive lean conditions, but that kind of rpm management is not going to be possible in any kind of driving scenario nor does it seem correct to me. I am also noting a fair bit of variation in the AFR at idle between startups, even after warmup enrichment expires. I have tried increasing enrichment values and turning off overrun cut for the time being, but none of that seems to be making any major difference in stabilising things. I have a friend with a very similarly modded Evo 6 who I used as a reference for accel enrich. Would love some suggestions of what to check and test. Part of me is wondering if my injector flow rate is way off the rated flow, or if my dead times are wrong (even though I have data for both). Kind of stumped due to a lack of experience. Have attached the map for reference. EDIT: Added log file AJD300 - Day 11 (enrich and overrun changes) 2.pclr day 11 - 3 (final).llg

I am logging the AFR in the ECU and as suggested I chose AFR Average because I am still using the 14.77 setting on the LC2 Innovate sensors my issues is the number showing in the log is way off because I also have a Race Tech logger and it read correct. Is there anyway I can log the AFR in the ECu by the old scale 14.77 Tony Logs Day head gasket Blew Wakefield.llg

hi I have a g4 link ecu and would like to view the afr in lambda. how do I do this? thanks
