How did you apply this soft bump with a hammer? I've seen a couple different methods of setting the tensioner and have not found one I have faith in...
After studying HP Tuners for a week, I have learned that my posted HPT log file is a good example of what the data looks like when the Goblin has an air vacuum leak. (Excessive LTFT and STFT at low RPM)Anyone with an LSJ care to share a HP Tuners log file? I want to know what "normal" is for my LSJ.
I logged all the variables available in HP Tuners, in order to find which variables work, and which don't.
I am curious if my results are typical for an LSJ engine.
Engine Oil Pressure = 0. 0 PSI Do I have a dead or missing sensor?
Startup Intake Air = -36F This log file was made today, in an airconditioned shop, about 75F.
Fuel System #1 Status (SAE) = CL - Fault
LTFT PCM Control = off Should my Long Term Fuel Trims be turned off? I would think not.
Misfire History Cylinder #1 = 148 Should I clear the history data?
Trans Fluid Temp = -40F
Trans Current Gear = 2nd Doesn't work correctly. I used 1st to 4th, and the tach vs speed tells me when I'm shifting.
TCC Slip = 1700 RPM Um, it is a standard, with no Torque Converter.
Fuel Tank Level = 42.9 gal The Cobalt tank isn't even that big.
Fan 1 Status = Unknown: 3F
Fan 2 Status = Unknown: 3D
Fan 3 Status = off

This morning I used a propane torch (with out the flame, just leaking propane) and HP Tuners to prob the engine for a vacuum leak, and I found out that my brake booster is leaking.
So rather than buying another 12" Cobalt brake booster, I am looking for a smaller brake booster.
Even the 315mm Nitto NT05R Drag Radial Tires don't need that much brake boost.
It would be nice if it mates to the stock master brake cylinder, and can be adapted to the stock Cobalt brake pedal. Any suggestions?
The wheel bearings were too loose, allowing the wheel to move around too much. Also those drag radials probably have more traction than what the kit was built for... Maybe we can convince Adam to design & offer some beefier king pin supports... but it is better those bend than the nice billet aluminum. Maybe the light weight (300 lbs/inch) springs and soft settings on the QA shocks played into it too. If I new that wheel hop can damage the king pins, I would have taken it easier on the brakes, so driver ignorance/abuse comes into play too.Ross,
So what was the fix for the king pin. Did I miss it? What caused the severe wheelhop Great vid by the way.
Well, it was before my kit, which was picked up in January of 2019. Not sure the date that DF changed this, but you did post in my build log, so I guess you are asking meWent back and looked at the Instructional video for the front suspension:
When did the design change to the L brackets?
