Anti-Lag with PFC pro.

Hello guys I just started up one of my build and tested it using stock injectors which I thing was fine for braking it in. I drive it and everything seems fine make good power, but like expected I can see I'm running out of injector duty. No big deal I have another set that are 850. And these are what I tend to run. But before I install them and take the car to get tuned. I decided to just pop in the pfc pro. To make sure it works. I uploaded my tune and cranked the are up.

It all worked fine. After the idle was learned. I tried the anti-lag feature. I see it uses the ac to set the ignition cut so I set it to 5k, and floored the gas. I only got about 7 psi and I'm looking for way more than that. Keeping in mind the injectors are still stock. I'm just wondering a few things.

 

1. How does t a anti-Lag system get the boost to go even higher. Does it need more ignition delay. And how do I do that with the pro. ??

 

How can I get this PT 7675 going. I'm after 22 psi or so off the line. Attached I have a photo of the screen. Opps it's saying this forum has disabled media sharing. Why.

you need use the combustion energy to turn the turbo rather than provide cylinder pressure. you want more ignition retard to burn the charge later.

the PowerFC pro is a piece of shit in 2017. pull it out and use a real ecu.

it's "launch control" is only an ignition cut instead of fuel, and an auxillary rev limiter.

its not a real launch control system.

ideally you want an ecu that can do TPS defined ignition retard activated by low road speed & a clutch switch.

Yeah. I still have the Haltech ps2000. I found out today the hard way that I f--ked up. I was under the impression that that it was an anti lag launch control. After I kept on flooring it and only saw 4 psi. So I guess If I want boost off the line I'll have to upgrade the ecu. We all learn differently and for me it's a hard to drop old habits for new ones. Even though people beat me up for it. Over the years I've seen more and more car over here state side run Haltech ecus. 

I'll have to start taking the time to get familiar with the ecu, and just face up to it. I did get me rb25 running on it and it worked pretty well, but moved back to the power fc. Bad habits I guess. To get the car going hard I dropped the clutch at 9k. The thing was an absolute animal and the turn worked well at 14psi. It took that much rpms to get that turbo going off the line. I also run the ets-pro so all 4 wheels smoked, and gate opened up right away. 

None the less I want to launch the car at a lower rpm, but with boost as I'm only geared towards drag racing.  I have a grudge match coming up Sunday. I'll have to run the fc for this. As it will take me some time to set up the Haltech. 

Is there any shops out there, willing to sell me a complete Haltech setup. Closed loop wideband setup as well even providing the injectors for 800 Hp. Along with a bit of advice and help seeing up injectors.  I ask because I'll need another one anyways. I'm also looking for the evo to be able to use a strain gauge for 0s88 that's coming soon. 

Thanks again and sorry I didn't use the Haltech. There I said it. 

Help me make this car go.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
