Own the Stett Chargepipe? Got a Meth Kit?
Last week I installed the Stett pipe and the Coolingmist stage2 meth kit.
I'm looking for others that have a similar setup as I have. I'm curious if others have had similar experiences. My Setup: 91 Octane Stett Chargepipe/Tial BoV using the 2nd meth bung CMGS Stage 2 Meth Kit will progressive controller 80/20 Denatured Alky/Distilled water mix Typical ambient 95-115 Typical non-cooled IATs are ambient+15degrees Cooled IAT's down to 60 - this is the CEL threshold Typical ambient humidity 5-15% Symptoms: The system is over cooling my IATs. If I set the spray to start at say 6.5psi and max at 15psi, the system will reduce my IATs by up to 50 degrees in just 1 pull. Such an extreme change in IATs causes the ECU to throw the following code/CEL: 2F09: 2F09 Inlet air temperature sensor, plausibility Error will cause a warning light Error is currently present Test conditions have not been completed Signal or value below threshold Event 1Odometer 12448kms 7734miles Intake air temperature 18.75 °C inlet air temperature at start 60.75 °C ambient temperature 31.50 °C Engine temperature 99.00 °C I can and have corrected the issue by setting the max duty on the controller/pump to 50% thus cutting in half the amount of spray. I ran a couple of logs to see how my timing is doing with the loss of octane from the reduction in alky and everything appears to be pretty good. I've attached a couple of the graphs. I tried to stick to 4th gear for the logs but kicked down a couple of times. Thanks for your input. Hopefully I find a couple others with similar setups.
