I put my Ball & Spring Boost Controller on today and at first it was on like full boost. Went right upto 14psi. It sounded insane and it felt soooo much faster conpared to the 6 i was used to. Turned it down to around 11psi but the boost holds really weird and my auto wouldnt change out of 2nd. It kept kinda spiking and fluttering away on my boost gauge.

Now my TCC Work BOV that I put on a week ago finally makes some noise as my boost it up. But it sounds bad...like a SSQ BOV and a Monza put together....

The crack in my radiator also grew around 15 cms and practically all my coolant escaped...I got some Selleys ARALDITE Super Strength to try to seal the crack but i wasnt successfull the first time as I got impatient after 6 horus and started the car to see if it would seal but it just blew holes through it, so im trying again overnight and hopefully it holds tomorrow.

I'm getting a new Aluminuim top tank made up and put on for my radiator on monday so that should be good.

Took my Ebay Ball & Spring controller off as it doesnt seem safe to me.

I got a GFB Atomic boost controller http://www.gofastbits.com.au/index.php?par...b_option=atomic to go on once my radiator is back.

These are probably a stupid questions but...

Can anyone give a straight answer about getting your engine re-tuned once a boost controller is fitted..?

If you don't does this lead to detonation, or leaning out?.. or anything else that may be detrimental?

Also what is a safe boost increase for a stock FJ with 2.5 exhaust and no cooler?... around 8 pound?

Cheers.

:D

I'd be putting it on a dyno to make sure its not leaning out etc etc, if thats all good then a retune isnt in order, if it is leaning out a retune is in order...

They already run 7 from factory, so maybe 10????

I've got an atomic boost controller on my HR30 and it seems to be holding boost very well and it's been on for about 10000km's running 11psi before I took it off the road to fix other problems.

thats reall good to know. when i get my new radiator in and motor back together ill be using a GFB Atomic Boost controller and by the sounds of it since it seems safe ill put it at 11psi :-)

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
