so for the people who have these how much boost are you making when the two step is enabled?

i know with most aftermarket ecu 2 steps you configure the amount of ignition retard, amount of extra fuel and rpm for operation and can make big boost on big turbo's for launch, but how configurable or useful are these standalone types that you are all discussing?

It will most likely hit full boost, whatever that may be set to

I know plenty of people that are using stutterboxes (fuel cut), and they make around 15psi

So I can only imagine, ignition cut will work a lot more effectively

I"m not really sure about the pros and cons of it.

I know that the Bee-R style simply cuts the earth from the system therefore the signal going to the plug cannot complete, hence no spark.

The Gizzmo style actually cuts signal going to each cylinder sequencially, therefore not dropping the same cylinder each time, which may or may not happen.

Dropping earth means that there's no control of exactly which plug gets dropped.

I guess the Sequencial would be better simply because it cycles between each cylinder.

I don't know which one would be better until you tested them back to back..

I reckon both make cool flames!

Turning them off wouldn't really be required, as if you are staging to launch RPM, which is probably going to be like 4500 rpm, you would be hammering your car anyway.

With the PFC, no. It's a complete stand alone unit, the PFC wouldn't even know its there.

I meant more from the point of flat changing because it would be shifting gears at full boost and I wouldn't want to constantly do this. I'm guessing I could just put a two phase switch between the power supply and the launch control.

Isn't the idea of these types of units to interfer with the signal going to the coilpacks and would therefore operate regardless what ecu you had. I know for a fact the Bee*r unit works with PFC because they installed one in the HPI r32 and it runs a PFC. I'm just not 100% sure on the gizzmo unit?

Yeah, that's what I mean. You install it, the PFC doesn't know it's there hence no changes are required.

With the Gizzmo, you cut the signal wires going to the plugs (from the PFC) and the signal goes into the Gizzmo and out the other side. When the Gizzmo wants to control rpm, it just doesn't allow the signal through.

Sh1t, these are so damaging for every aspect of your car, but I want one sooooo bad!!! My question is can they be turned off for when you want to only hammer your car and not kill it.

couldn't you just set the launch rpm higher than the redline rpm limiter?

edit: from what ive read, there is 3 knobs on the Bee-R limiter, Rev1, Rev2, and Gain.

Rev1 sets your redline limiter.

Rev2 sets the launch control limiter.

and Gain sets the frequency and length of limit.. setting gain to 0 disables the limiter apparently.

I don't see the point in wanting to turn it off.

They run off a switch on your clutch.

When the clutch is in, the RPM limit is set at say 4500rpm

When the clutch is out the limiter is like 7500 rpm

The only time you would encounter the launch rpm limit is if you had the clutch in, and dialed up more than 4500 rpm with your right foot.

The only time I dial up 4500rpm with the clutch in is when I'm about to launch pretty freaking hard, and it's then that you want the boost on board.

i was thinking the same thing, its not often you would have the clutch in and be anyway near the launch rpm...

yep, I just thought it would be easier to have switch so you don't have to screw around with the settings every time you want to use it.

set the gain to '0' and it disables the limiter.

Question:

Won't cutting the ignition to all the plugs with the throttle open (BeeR limiter) cause the plugs to get fouled? (ie. bad)

Whereas with the Gizmo one the plugs won't get as fouled cause they are still being sparked?

Call me stupid but how dos this affect the limiter when heel toe-ing down a gear....

clutch in, right foot on anchors and accelerator, heel toe to 6K for example, wouldnt it hit limiter?

But as mentioned its probably not a great device for track work, just drags

No, they both work almost identically.

The Bee-R cuts spark to earth, therefore all cylinders.

The Gizzmo cuts spark to each individual cylinder.

Both systems drop spark.

Both systems have the potential of fouling plugs, but it's not like you are sitting on the limiter for hours.

      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

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

      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.
