No calculated A/F. Just the O2 numbers.

Hope to install the Dynojet Wideband this week. May have to wait til Friday. Have to take a look for the best place to put the bung. Will it still run in closed loop if I temporarily put it in one of the rear O2 holes? I have no way to turn off the stock sensor.

 

Back home now. Thought I would try something. Disconnected the battery for a while. Reconnected and went for a ride. Way more power (and clunky downshifts the first couple of times). But .... the pinging was back!

Drained most of the gas from the tank and filled up with 94 octane 10% ethanol blend. Disconnected the battery again. Will see how it runs tomorrow.

 

Also noticing that my IAT is running about 30 degrees above ambient while cruising. Around 117 when it was 87 outside. Is this typical?

 

That's about right on the IAT's. Mine runs about 30 deg. above ambient when normal cruising.

 

how did it run today?

 

Reconnected the battery and started over from square 1 again. No pinging! Power seems to be holding up. Still not sure if it is quite where it should be though. Only put a few miles on. Will take it for a longer drive after supper and see what happens.

 

yeah...when itis cooler...have you thought about putting on a dyno?
this might be a silly question....but did you put the Radix/superchips tune on?

 

good question.....

 

Peak MAF readings seem a little low to me at WOT,...anyone else? Did you monitor KR.




BIG TEX, thanks for the welcome! I have been lurking on here under a different name for some time now. The Radix setup is doing quite well. I have gone to the dyno several times as well. I want to hit 500HP to the wheels before I post the dyno sheets. Currently pushing 474.

FYI, the MAF is pegged by 5750 RPM's with the 474HP run (8psi, 2.9"). The magnaflows in place of the flowmaster's did NOTHING on the dyno. Waste of money IMO.

 

Just took it for a hard drive. Outside temp was 70 degrees. BTW my outside temp sensor is now reading the temp of the air that has passed through the intercooler heat exchanger because it sits right behind it. Will have to relocate it if possible.

Definitely running better but still seems that the PCM permanently cuts me back a little more after every WOT dead-stop launch. Started out with about 5 ft of tire squeal(don't know what this thing should be doing). By the end of testing I was down to a chirp(first run after install last week did about 20 ft on the exact same spot-with some pinging). Can't say for sure that I noticed any ping. Could just be paranoid. Seems like I may be getting a little more juice out of it if I start from a slight roll.

Don't think I can blame anything on the gas now. It would be impossible to tune one of these to run at higher boost levels if 94 octane is not good enough for the stock Radix setup. Could be that the 94 is just masking something else.

It's not bad so I'll drive it for a while until the rest of my gauges come in. Will talk to the guys at the shop that's getting them about putting the AV on their dyno.

Have installed and reinstalled the Radix tune. Factory tune is probably only good for idling now.
