race pellets

just wondering if these race pellets actually work that i keep hearing about and what kind of gains you see
 


Wanna know a secret? just unplug the IAT sensor and it will automatically show like -35 degrees.

I'm not fond of this....you would be better off having a good CAI and leaving your stock sensor in.....or.....you could wait and purchase a modified IAT from yours truly. :th_thumbsup-wink:

It reads 99 actually brian. not sure if it is in *C or *f though, Alot of sensors read that way when unplugged r bad.

Oh yeah???

I sware it read 99 on mine. I will take a pic next time i go over to my brothers house and am tuning on his laptop so you dont think im crazy since my laptop is still broken. I actually learned this when doing our iat testing. Map also reads 99 when unplugged on my car.
 
Map will read that.

IAT, and the ambient temp sensor will defailt to -40F in the case of a sensor failure. -38F is close enough. :p
 
I don't remember seeing any timing being pulled on that side of the air temp table...but it could default to a certain range if the sensor is bad or missing.
 


ZZP put one on my car and it worked well enough to get 500whp on my setup.. I still have it if you want to buy it. lmk.
 
yeah it actually adds timing on that side of the table. 1 or 2 degrees if im not mistaken. And you know what now that you mention it i think it was the map that i was talking about when i said it reads 99 when unplugged.:th_doh: The only way the pcm should pull timing on a stock iat table is when the temp reaches 122*f or something around that

HRM. I thought for sure that it pulled timing at the -40 mark too... just since -40 usually meant a failed IAT, and the PCM would err on the side of caution.

Now I have something to do on my ride up to Green Bay in 20 minutes. :D
 
not according to the table at least...but correct me if im wrong as i dont have my tuner in front of me...im always willing to learn something
 


good point and very possible...especially if someone see's a decrease in timing.

You are correct. Stock tables only have timing pulled when the temp is high.

I have mine set so that at -40, it pulls 3* of timing. I have seen multiple IAT sensors fail and read -40, so it is set as more of a safety thing than anything.

Thats a good idea.
 
i have my air intake temp +10* when its showing -40*F:th_lipssealed1:, but i have the happy knob set at 14*F which adds approximately 5-6* of timing from the stock 15* which im currently running ~20-21*:p. more/less timing at the switch of a button:D
