my tuner says that the Maximum Delta Airflow shouldnt have to be touched.Īny ideas? i do not have any tables, logs, or files to show you. To save valueble 'tuningtime' use HPTuners and change your Stoich AFR to 9.799 (look at picture). The car idles rough and fueling WOT is not what id like it to be (ie flat), but the car drives okay. Empty your fuel tank, just run the tank as empty as you can, Doesn´t really matter if there is some gas left, When you fill it up the next time you´l know you only have E85. I have quite a few different tuning software/hardware solutions but none of them can do Alloytechs. I predominantly tune ecotech V6s and LSx V8s but am getting a lot of enquiries about Alloytechs. The throttle blip doesnt really work for two reasons. Yes I have a working and properly calibrated speed sensor to the ecu. I was told that he had messed with the MAP tables to try and combat low vacuum made by the camshaft, but after the CEL was set, he flashed them back to stock to no avail. Hello I am a tuner based in Napier, New Zealand. If you cant fix it in the ECU tuning, you could just blip the throttle when clutching in, so that you exit the idle control and start fresh. My question is, is this from VE tuning, or MAF tuning? does the Delta threshold need to be larger? is there something he missed? It is a long story why And I do not worry about damaging this engine because of lack of knock sensors. I have to use my engine without kock sensors. These tools are available on the Tuner Tools page, where your account information is shared with your main HP Tuners account. its still very basic, but i tried to add a little bit more content to it, im sure ill add more as needed. Ive modified some of the content, and tuned my Ls2 GTO with it. when these values exceed Maximum Delta Airflow, it illuminates the CEL and possibly puts the car in Speed Density as a safeguard. Can someone tell me how to disable knock sensors in PCM in my 2004 GTO, so it will not pull 3 degree of timing at WOT. Tuner Tools brings you various industry exclusive and highly useful services that supplement the already powerful VCM Suite and MPVI2 interface. This Doco came from the LS2 basic tuning guide that can be found in the stickys. the pcm does a "rationality check" against Speed Density values to check the MAF. i was also getting a CEL for p0101, MAF low performance.įrom what ive gathered, this is a code that gets set when MAF values do not meet coded value for MAP (ie SD). If you want to increase the tuning potential for your LS engine, there are quite a few options. my fuel curve wasnt pretty, and it was leaning out quite a bit at the end. The controller includes the MAP sensor and is compatible with all LS-series ignition coils. Just installed a camshaft in my LS1 and got it tuned by my tuner.
