Id say thats pretty well cooking. About the highest mine sees is about 1100 F. Mine is mounted in the downpipe.
Ours is mounted about 2" from the exhaust port on the head.
Just for sake of comparison, the stock N/A 3L I had with the egt in the same spot would make about 650*C under cruise, and about 800*C under full throttle. Now that was a stock SVT injection system and PCM mind you! :shocked:
The temps are much lower when the egt is a couple of feet further away. Never can compare EGTs unless the probe is mounted in the same place.
For us, 850*C is about the limit. When we saw EGT hitting 900*C AND the Air fuel hitting around 14:1, it was time to shut it down.
We found that something is triggering the pcm to go open loop all the time and when it does that the pcm tries to lean out the injection. Then when we went full throttle it had leaned itself out. When we cut the motor and restart, then the computer resets and has normal air fuel. We don't know what is going on with that yet but will keep you posted when we figure it out.
Oh,
for the guy who keeps asking: we do dyno tuning when we are at the dyno and we tune from datalogs taken both at the dyno and on the road.
We are now perfecting the tune for the kit so we will test it on the road, at the dyno, and at the track.
Driveability is already VERY VERY good on this tune and this kit. We just need to get that A/F problem fixed and the tune is done. Timing tables are already nailed.
This will be the standard tune that will be available with the kit in a file format. We are deciding to provide the file "locked" so it can't be read by anyone else, but provide the tunefile converted into the appropriate PCM code to the buyers of our kit who don't have us do further tuning. This will be a basic safe tune for you to load into your own XCAL2, or any other dealer/dyno operator can load into your pcm and get you up and running right away. Detailed tuning can be done through us even at your local dyno, we will just make an appointment with you where we will be on call on the phone while you are on the dyno and as you make a run, I'll make any adjustments and then email the tune to you immediately, or to the dyno's email and they can upload the changes.
Hope this explains our vision of how we will provide customer support to people who are far away.
