That shouldnt be related to the BOV perhaps there is clutching issues. To bypass the BOV solenoid you simply hook the BOV direct to a vacuum source.

I added the out the hood intake this weekend. Before the intake my tune was spot on at 12.0 AFR at WOT using the powercommander and autotune. . Fuel trims were at zero. It appears the intake pushed the trims to about +10 to +12. So it would appear the intake makes the sled flow a lot more and...

Any update to this?

I believe the PCV will only allow the autotune to adjust trims between 11.5 and 14afr. If your at 10.0 it wont adjust fuel.

So attached is a pic of my commanded afr and the map it produced. Some areas its adding up to 30% fuel!!!! This is with a aftermarket GGB can on the sled. Over the weekend i will put the stock muffler back on and do some runs and then put the can back on and add a intake and see the difference...

Have you used the autotune module on your sled? Or are you just manually adding fuel to the PCV map by looking at the rpm and pressure and increasing by 5-10% or? The autotune makes it so much easier. you just load up the afr vs map and rpm and drive it. Works AWESOME.

Another reason I like the powercommander better. I get to determine what AFR i am targeting.

I picked up the autotune, pod 300 and a PVC PTI for a viper years ago for about $150. I then purchased the correct PCV for the sidewinder and used the map, autotune, pod300 and wideband O2 sensor from the viper setup I had. Why not go this route? another interesting thing is that my wastegate...

After seeing so many posts/threads about a can/intake leaning out a otherwise stock sidewinder I thought id do some testing myself to see the differences. First I installed a wideband AFR gauge on the sled (sled already has a aftermarket can on it, bought it that way) The AFR's were in the 14's...

It’s just a 2 wire solenoid. The ecu isn’t monitoring anything with the bov. Just opening or closing that solenoid. Wont hurt if it’s bypassed. Perhaps mine was frozen. Not running anyones tune. Currently I have a aftermarket muffler and power commander with the wideband2 module. Going to...

What is the point of ruing the BOV through the solenoid? Why would you ever want the BOV to not open if you were in boost and let off the throttle? Interesting that all I heard from my sled was surge after letting off the throttle when it was ran through the solenoid. I bypassed the solenoid and...

You probably won’t like this idea but on my build I welded a bolt in one of those spherical bushings at the spindle end of a Nytro a arm. Then welded the outside of the bushing to the steering shaft. Has worked great so far. Just don’t get it too hot welding it and melt it. I don’t think the...

Until Wednesday

Tial gate is Teed into the stainless header right after the collector. Factory internal gate actuator is removed with the flapper forced shut. Shouldn't matter where the Tial is installed as long as its after the header collector and before the turbo housing.

Internal or external gate shouldn’t make a difference at all. They both have a line to the top and bottom of the gate to control boost. Assuming they have the same crack pressure point it’s going to make no difference. The external gate was actually much better at controlling boost as TD said...

Why not tee in the stock map sensor, boost gauge and the 4 bar into a length of rubber line. Pressurize it and compare readings. Should have your answer pretty easily.

All I heard before bypassing it was surge as well . There is no way it can reduce lag. If the wastegate is closed and the bov is closed there is no way it can help reduce lag. I also think bypassing the bov solenoid fixed my random sd26 codes.

Cool to see this thread alive again!

What is the purpose of the blow off valve being run through a solenoid? I have my blowoff valve solenoid bypassed and the blow off hooked direct to a vacuum source. Now I can actually hear the blow off valve. Almost seems like when it was connected to the solenoid it wasn’t working at all.

Does the powercommander adjust fuel via rpm and tps only? Doesn’t seem like a power commander pti is offered for the sidewinder to be able to adjust rpm and map
