![]() ![]() How should I go about testing/cleaning out the injectors? Or should I just go on Marketplace and get a set that I know works? I also went ahead and cleaned up the MAF curve in my more recent tunes. Injectors are the only thing I'm not sure of yet, as they did sit for a while and could be plugged up. Spark plugs are not new, but are in fair condition. How would you recommend verifying the status of the filter, pump, and pressure? Plug wires are in good condition and are fully connected. Also, noted your MAF curve is jagged.So right now, I am using an analog connection to the WB O2 sensor, using a MPVI3, Innovate LC2, and a ProLink+ cable. I think it is possible you are chasing a mechanical problem vs tuning. I would consider verifying a few mechanical components,clean up the log, then start fresh. The axis of throttle angle predicted would begin similar.02. Looking at your screenshot with the cell values to the tenth. Increasing your ETC area by 1.7xxx would require changing the axis of throttle angle predicted, to. If that cam is what I think it is, a near stock tune would work. The axis of one table to the cells of the other table. If that cam is what I think it is, a near stock tune would work. A misfire will cause a LEAN reading by 02 sensor on that bank. COIL, INJECTOR, ROCKERS, VALVES, COMPRESSION, VALVE SEAL, etc. are plugs healthy? What do they look like? if that plug is dirty compared to the rest, better check everything. PLUG WIRES? good shape? Did you see the misfire on #1 and I believe #8 also as soon as you increased throttle? Could be a plug, etc. Verify fuel injector harness connections. Oil pressure logging issue.ĭid you verify the fuel FILTER, PUMP, and PRESSURE and make sure they are good? How about the INJECTORS? I would take them out and check flow, resistance, etc. its easier to use that way plus gives you status data on the wb. change the innovate to a serial connection. Any help would be appreciated, as I need this truck on the road by the start of the fall semester. Does anyone have any idea why is is continually so lean, as well as why my changes don't seem to make any changes on the scanning side? When I make those adjustments to the tune, I can see the values changing appropriately on the MAF chart, but when I take a log, it almost always ends up very lean, or at least reading as such. I'm using a Bosch wideband O2 sensor, as well as a Innovate LC2 to interface it to the HPTuners scanner. ![]() As I try to tune it in increments, as GRG advises, it seems to make small changes at idle, but as soon as I rev it at all, it immediately reads lean. Using techniques from Goat Rope Garage's channel on YouTube, I've been tuning the MAF, but without much luck. I have a 2000 Silverado 1500 5.3 that I'm tuning currently, and the only modification it has is a "torque" cam from Summit Racing. ![]()
