eh he flipped some tables. didn't take anything, didn't hurt anyone. being that they were in his house it's more like telling them to gtfo after they had been putting out they cools on his floor.
and if anyone got the reference, he may have actually had a rug from persia

Anyone else enjoying Shiv's 1.5dump tune as much as I am

Where did you get the 1.5 dump tune? Didn't know it was out yet.

You should also be conscience that if you activate the ESC and immediately clutch in you can stall the car. It is pretty hard to do and it isn't really how you should drive a manual....it should always be in or between gear unless stopped.

Hey are you saying that one should not punch the car to WOT from a red light to launch? At stop the rpms are low and below 2500. Also one should not rev the car up to 4k and dump the clutch?
What do you think is happening to the car that causes it to shudder and stall under these conditions?

Thx

It depends how you launch the car....most people aren't truly WOT until 2500RPM when they launch anyways so it would be a non issue. You can rev the car up to 4000 rpm and dump the clutch so long as your clutch will allow it ......see below example of what happens with a 3500 Rpm launch

I think he was having a different issue where his compressor was turning on by itself without WOT. If the compressor turns on when the throttle is closed it will force air into the engine when it doesnt want any and cause it to stall. This condition will typically only happen if the brake isn't set fast enough to slow the compressor after a WOT run and clutch in. If the compressor is spinning when the car is idle it will most likely stall.

Yep, Rob is fixing my issue. Drag reduction was set too aggressively and at sea level in 80/90f heat made it detect what it thought was negative pressure.

I've done alot of WOT pulls in 2nd gear at 2K RPM, feels awesome. Motor never feels stressed. Now if I'm at 2K in 5th/6th thats a different story, I'd downshift to get RPMs up-to 3/3.5K before going WOT.

Good to hear bro!

Agree. 2k in first or second is no big deal. In 3rd to 6 I usually shot for 3k+

sounds like we need a relay hooked up to some rpm signal, so it will open/close the throttle switch circuit only after a certain rpm. Like SPM only rpm based not a secondary button.

on second thought, that seems like over complicating the issue by fixing the symptom insted of the problem. I wonder if the controller could be programmed to engage the esc more gradually, allowing the ecu to compensate insted of running lean. I don't think modifying the tune would help, because the boost is so sudden it has no way to anticipate.

Rob put me on the waiting list and I'm pretty excited , can't wait to try this out!

How long do you think the wait might be and is the kit set up for the 1.5 dump pack?

Just tell rob you want the 1.5 pack.

Ya that was a edge case. Under normal condition you will never engage that low.

Yes the controller can be programmed by Rob to come on slower but that wrecks all the fun of the ESCs instant boost.

why does it stall? I thought it would just run really lean. Perhaps the lack of fuel while at 0% throttle and incoming 02 causes it to stall? Is this what's happening.

No need for a blow off valve has always raised a brow for me. Another question, if the braking for the turbine does not work correctly, like it did in this example, do you think it could create too much boost with nowhere to go? I love this concept and I am really toying with its purchase. Excuse my ignorance I am trying to understand. thx
