An effective method to determine false knock exists is to:
1) Pull a bunch of timing in the area of knock counts
2) Run high octane fuel (100+) temporarily. Probably get away with torco or...
Send It!
I didn't explicitly say IAT caused low air flow ahaha, I implied if the IAT reading is incorrect (as in reading low) it could explain a lower airflow at a given boost level. My current...
Kinda along the lines of what I was thinking, basically pull the sensor and take points compared to an external TC (figured water would be close enough and sensor safe). If my scaling happens to be...
Thanks for the input! I was questioning it because the E67 IAT scale was quite a bit different than the vendor provided IAT. When I manually entered the new IAT scale that was provided it wasn't...
I swapped in a 3-bar MAP/IAT on the E67. I took the MAF IAT input and wired this to this new MAP sensor. The IAT calibration in HPT for the E67 shows resistance vs. temperature.
I found...
Using this sensor on an LE5 (2006 Solstice) with the E67: https://www.bmotorsports.com/shop/product_info.php/cPath/129_143/products_id/1721
I took the two wires from the MAF sensor IAT and...
If you can feel the misfire during WOT (torque loss "blip"), then you need to close your spark plug gaps further. Like 0.028-0.030. It's that simple, again for misfires during WOT pulls.
Does reducing timing at the spot where it shows KR do anything? If KR is still present and you pulled a bunch of timing, maybe it is false knock. Find some high octane fuel or use the...
This might be the hack way I am also new to this; from my experience installing 80lb injectors driven by a E67 LE5 ECU, you can trick the computer to do a global change to fueling. If you're going...
Is it actual knock? What RPM? about 5,000 rpm?
With a full ZZP exhaust system, I can easily hear actual knock in my Cruze 1.4T. It sounds like someone is perpetually snapping a bundle of...
Are you on the advanced tuning mode in the HPT editor? editor-edit-view-basic/standard/advanced
Playing with the timing is something you can do at your own risk and if you don't know what knock sounds then you're playing with fire in a bomb factory. I have a 2006 LE5 (stock forged crank/rods)...
- Try to "unlock" torque management, max all the stuff out. This should increase area under the torque curve, but not so much peak power.
- Look into getting setup to run E85, you'll be able to...
I haven't done it myself, but yes I have read changing the MAF sensor is an option (we hope someone with xp will confirm or deny). Will need to update the MAF calibration with the same specs as the...
:p
Maybe you are super lean or super rich, do you have a wideband? Is this under WOT? If not, check under light load, STFT should be cycling positive/negative or the O2 sensor should be bouncing...
I wonder if this is still valid for logging WB02 without the inputs: https://www.corvetteforum.com/forums/c5-scan-and-tune/1705471-connecting-wideband-via-egr-or-a-c-pressure-in-hp-tuners.html
I agree with mJolnir comment, Lambda does not care what fuel you're using. Off the shelf WB02 gasoline gauges are calibrated to output 14.7 when it is reading Lambda 1.0. So if you want to run 0.78...
You need a wideband O2 sensor to tune WOT. WOT causes the fueling system to go into Open Loop. LTFT/STFT are Closed Loop values; you must tune closed loop areas with LTFT, a WBO2 won't help with...

I had very limited experience calibrating / tuning and I also noted access to simple...
Your HPT license will be matched to the ECU. My understanding is, you can't just take another vehicle cal and flash it, you will first need to read the ECU (and license it), then use the "compare"...
Here is a start for beginner calibrators: https://www.youtube.com/watch?v=u1wzEVwAfJQ
Here for injector scaling without data, from there MAF tuning will take up errors: https://www.youtube.com/watch?v=eC486sOyTeQ
I suggest adding details like what you mean by needing help tuning your car. Are you the tuner?
