Just curious anyone running anti lag tune on a bi turbo setup… guessing the benefits aren’t too rewarding … to be honest I do the like the shooting flames on revving though … I know it might not be good for the longevity but i do think I would enjoy the flame shooting in front of crowds. Take it however u would like, 😭

Engines are expensive. You already mentioned having thermal management issues with your car, anti-lag dramatically raises EGTs and can easily damage a cylinder head. If your goal is actually to improve transient response I recommend VCAM. DBW can also help here. Instead of a simple mapping of accelerator pedal position to throttle opening instead you interpret the accelerator pedal as a certain torque/power request and the throttle will open more or less to achieve that. So if your desired acceleration requires getting 0.5 bar of boost the throttle will silently go wide open to spool the turbos, then as it gets to that target intake manifold pressure it will adjust the throttle back to the steady state target. Another trick you can play is detecting when a shift is happening using a strain gauge and clutch switch for example and rather than snap the throttle shut when the accelerator pedal closes you cut fuel injection and hang the throttle open to keep the turbo from slowing down. This is a pretty complicated trick to play though as if it got stuck in that logic you would have engine runaway and you want to make sure the engine RPMs actually fall at a reasonable rate instead of rev hanging badly.

Sounds like all you want is a button on your CAN dash pad that is for 2-step / anti lag launch. 

Hold the button down, rev limit gets set to whatever you want, say 5000 rpm. Then mass timing is pulled and a heap of fuel is dumped in for fun times. Want more bangs and flames, pull more timing or add more fuel or both lol. 

Obviously the more you use the fun button, the shorter the life of the entire hot side of your motor. So valves, turbo, cat, any sensors in the exhaust, etc etc.

Well, if you are using it for its intended purpose it is very rewarding. If you are at the drags and want to launch on full boost, how else are you going to do that?

Hahah yeah but a man got to do what a man wants to do. Won’t be using it infront of the 5O anyway. My car is illegal as is with the mods.

Thanks for the info… guessing less rewarding for my hks ss turbo setup. Might just be more beneficial for a single turbo. I’m just concerned it will hurt my engine long run which would be very expensive.

Well not really, 2-step doesn't care if you have 1 or 2 turbos. It will function the same either way, it will let you build boost while stationary. 

You should be concerned, it will 100% hurt your engine in the long run. But you want to shoot flames and have crazy pops/bangs yeah? lol.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
