oi i was gonna say the blitz sbc id3

or u can also go the hks evc iv

seriously, go look at the information for all of the mentioned boost controllers, then see which one suits u, and u like the look of, depending on price also, u can also get the ricey sbc color.

meh.

What about the Hybrid 2-stage electronic boost control?

Has anyone got anything good to say about that little gadget? I bought one simply because it was a good 'cheap' price for a EBC.

Yeah and despite those features they are still a pain in the ass to use and still dont hold boost better than a decent bleeder IMO!!! Go the Blitz...

...i no longer use an AVC-R, but did for 3-4 years with both the std turbo and a Trust turbo. The thing worked extremely well, never spiked, held stable boost. I was vert happy with it.

There have been several instances where ppl claim they have not worked...i just cannot understand how this can be the case. If you understand how they work (which aint rocket science, just read the manual) then they are even easy to setup. The instances where they have not worked 100% have usually been traced back to not being installed correctly, with wrong diameter hose, undesirably long lengths of the incorrect diam hose etc, its debatable whether any EBC woudl work optimally if installed in the same manner?!?!?!?!?!?!?

And they are a very flexible EBC, and the variabel duty cycle works very well as my std wastegate presssure is 0.65bar, and with the AVC-R set to 1.25bar it held boost just fine. So thats 9psi to 18psi and it managed to control boost. Others seem to say that its very difficult for an EBC to increase boost so much beyond what std spring pressure is, AVC-R did it.

Who gives a shit about a gain function when there is a PID loop trimming the boost to the desired level. This is how the autronic boost controller tables work and it is well impressive.

What you really want is a boost MAP, RPM vs Load just like any fuel or timing MAP. This way you can eliminate the wastegate cracking to early.

I dont think you can compare a bleeder vavle to a ebc. ie if your wastegate spring tension is 8psi and you want to run 15-20psi how is a bleeder going to hold the boost further along in the rev range when more and more pressure needs to be bled from the actuator?

If only everything was linear eh..

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
