What BDC is trying to say is with the setup your running its not consistent, and rather risky.

Why is my setup risky?
Again I say elaborate.

I have plenty of fuel, s-afc, fcd, 4x720cc, Walbro, performance BOV.
Basically everything everyone always says to get when upgrading exept a front mount and tons of people run 10 PSI on hybrids with top mount.

Tell me where I am risky besides top mount (which isn't risky only running 10 PSI) and it's cold here right now.

That thing is going to heat soak like crazy. Spray water on the top to help out. Hell, bring bag of ice for it between runs.

Also, if the tuner wants to put the wideband sensor in your stock bung that might be a bad idea. The EGT on a rotary is much more intense than a piston engine. That location might over heat the sensor.

I tail pipe probe will have to do. I have always heard that having the sensor after a cat will affect the reading. However, I read a paper that said it didn't.

So did you get some numbers for us?

I'm going next week.
He's using a tail probe (no cats) :)

I'll have a fan and water.

Whoever wrote *the paper* is nuttier than a fruit cake. Find yourself a modern car with OBDII and connect a scanner like a Actron CP9150 to it and monitor the 02sensor that resides prior to the cat and the second 02sensor that resides after the cat. The second 02 sensor will show a steady state while the one prior to the cat will constantly read/jump above and below stoic.

Any other tips on af ratio at idle, cruise, and WOT.

I now have my s-afc wired for boost not throttle sensor so I should be able to tune all three pretty well.

My s-afc is set so lo is anything below 0 PSI (vaccuum, cruising and idle) and the hi is anything above 0 PSI with 100% throttle at 12 PSI. I should be able to get a pretty linear af map.

I've got two turboii and they both idle good at 13. The closer to 14 you get the more the cars start to sort of miss. 13 and below and they don't miss and the idle is just fine and dandy.

Something you might look at sometime while messing around. Take a look and you'll notice that the tps reaches full travel just as the secondary plates start to open. That should give you an idea of where the tps is when it shows 100 percent.

I'm not using the tps for my s-afc.
