    I looked at my old maps with the Innovate LC1 and the AFR read fine ... so I am guessing it is probably due to the AEM UEGO that I have now. I will be replacing it with the AEM X-series. Waiting for it to arrive. Will update after I have it installed. Thanks.

    I see. So I thought wrongly. I was thinking I should try to measure the voltage from the gauge to the ECU to make sure the readings on the gauge is correct. And maybe also to run the ground to the sensor ground on the XS Loom?

    hmm... I think I should check the wiring first instead of meddling with the calibration on Cal 4... cos I wouldn't know which is correct in the first place ... alternatively I am considering getting the AEM X series. apparently the reviews are quite good and it is not too costly too ... I looked at the wires from the AEM gauge, basically they only need one single wire to the ECU, which in this case is my AN Volt 2 input. The ground is to the gauge's power ground ... so highly unlikely it is a grounding issue ...

    And so I did the changes as advised, the Lambda 1 is now calibrated to Cal 4. I did a brief run and realized that the AFR on the gauge and in the log is different. The AFR logged is showing that the car is running lean (previously running very rich when calibrated to AEM X series spec) compared to the Target AFR, whereas the reading on the gauge is very close to the target AFR, maybe difference by 0.2. I am assuming that the tuner might have tuned the car based on the readings on the gauge. The question now is, should I retune the car based on the logged AFR readings instead? I am also assuming that I cannot turn on the closed loop lambda yet ...... Thanks.

    Thank you Adam. I thought it looked non-linear, my mistake. I should have used my calculator to check. Very much appreciated!

    Thanks Adam. I have since changed the frequency to 200hz. I will see if I can adjust the fuel table after changing the short pulse width adder. @ Adam... I am using the AEM Wideband UEGO. http://www.aemelectronics.com/products/wideband-uego-air-fuel-controllers/digital-wideband-uego-afr-gauge/digital-wideband-uego-afr-gauge I tried to input the specs provided into Table 7 (uneven spaced non linear output), but there was not enough cells. So i selected the "AEM X-series UEGO" for the calibration. However, I realised thta the Lambda values in my logs is different from that displayed on my AEM gauge. I tried to find the data in the pre-assigned "AEM X-series UEGO" but there is non available. Please advise how I what I should do as I am unable to turn on the closed loop lambda because of this. I did not have this issue when I was using the Innovate LC-1 previously. Thanks.

    Yes, I bought the 1000cc EV14 injectors from NZEFI. I am not too sure about injectors specs though. Maybe the more knowledgeable here can advise? Just to add.. the minimum pulse width is 0.1408ms... don't think it is negative ...

    Yes, I am using the AEM UEGO wideband. I did notice that the car was running rich too. I will need to do another logging when the car is warmed up sufficiently. I am not sure about the idle ignition table, as I do not have knowledge about it. this is the first time I come across a tuner using the ignition to control idle. As for the minimum injector pulse width, I have since changed it to -0.1408ms as per the Bosch EV14 specs. I did try to put in the pulse width adder information as provided, but the idling became worse. I am running the stock IACV. If 15hz is too low, what should be a proper frequency? I read that the recommended value should be 200hz in the Link Help menu? Thanks.

    I was considering increasing the idle rpm too. I will have to look into the idle ignition webinar. Thanks. Attached a cold start log from this morning. Log 2017-07-6 8;11;09 am.llg

    Noted with thanks Adam. I have since redone my maps and the car is running much better compared to the previous tune. However, I was thinking the idling is still a little lumpy and could be better. The new tune is using ignition to control idling now. I was looking at the tune and realized the minimum injector pulse width was set to 0.00ms. I am wondering if this might affect the idling? Greatly appreciate if you can take a look at the map. Tomei RB28 on Bosch EV14 1000cc injectors. I was told the injectors are too big... Thanks. joel04072017.pclr

    I forgot to state that I am running a single throttle, not multi throttle. Thanks.

    My car is running on Tomei RB28 Pro cams. The intake and exhaust are both 270° and -10.25mm lift. I was told these are high overlay cams. According to the Link help menu:- The Lambda/AFR Target Table on Multi-Throttle Engines Link G4+ ECUs has a very powerful method of tuning engines with multi-throttle or long overlap cams. This tuning is based on both TPS and Manifold pressure. The Fuel Table Y axis is based on TPS, the Lambda/AFR Target Tables Y Axis is MAP or MGP. The Target is used as a look up table for manifold pressure changes. Based on the values in the Target Table, the ECU makes corrections for manifold changes in the fuel equation to adjust injector time. The Fuel Table is tuned based on TPS and the ECU automatically looks after the changes in manifold pressure. Another advantage of this method, is that the Target Lambda/AFR of the engine can be later changed without needing to retune the Fuel Table.The settings required are, ·Equation Load Source: Load= MAP·Open Loop Lambda Table: ON·AFR/Lambda Target Table Y Axis: MAP or MGP·Fuel table Y axis: TP(Main) So should I request my tuner to use the TPS instead of the usual MGP? Thanks.
  13. Yes, I am running single throttle. But i have Tomei's camshafts, both IN and OUT at 270 - 10.25. I was told the cams are overlapping. Is that the reason why he might have considered using Alpha-N? I am not sure why he told me he was going to tune my car with Alpha-N when he used a MGP instead ... mind boggling...
  14. I just remembered the tuner used something called the Alpha N to tune my car??? Any idea what that is?
  15. Thanks Adam. Will adjust as you suggested.
