Yeah, the dyno says 10hp gain from with the dump+front pipe, but the on-road performance is huge. Full boost by 2600rpm makes the car much more fun to drive. Its running a lot smoother too, seems I needed a new set of plugs after only 25000km's, damn platinums are expensive.

with the ecu (autronics I think, 90% sure), plus fuel pump or fuel regulator I hope to make 300hp @ wheels. Then it'll be time for injectors, pistons to make way for a gt30 I think

As per my post I'm doing a few cosmetic things now, like I've had a set of side skirts since november last year that were meant to be put on before I went to the UK in december that still arnt on yet Plus paul has some rims for me, then I think a catch can after seeing the oil in the intake manifold today and a ogura flywheel as well

Paul, I have a blitz dual SBC, last time I looked that was an EBC

my cars all fixed, read my post in the WA forum.

After fitting a hurricane pod from autoworx I ended up with a big misfire problem. With the hurricane pod on the car was running very rich with boost set at 0.6bar as extra air was flowing over the AFM it seemed to be dumping in a whole heap of extra fuel, on 0.8bar I kept on hitting some sort of fuel/boost cut as soon as the turbo spooled up to 0.8bar. Putting the HKS pod back on fixed the problems so it was narrowed down to the ecu needing a reset with the hurricane pod on. Tried to do this the next morning, but I dont have the key from cyclops to disable my siren, so I couldnt really reset the ecu for any long length of time. Having no success I decided to go back to the HKS pod, this time at full throttle on 0.6 and 0.8bar I was getting a baffled "pop pop pop" noise from the exhaust. I thought it was a misfire, other people told me it wasnt. So at SST today we fitted up a combined wastegate and exhaust gases dump pipe with a much larger flange stepping out to ~2.75" at the front pipe as well as a 2.75" to 3" front pipe. We fired the car up on the dyno and the noises start again, steve confirmed this was a misfire so we pulled out the plugs and put some new platinums in I was saving for the ecu swap-over. Ran the car up again, now its only a 10hp gain over the last dyno run (just dump+front pipe this time) but the on the road gains are HUGE. Boost is coming on faster and harder and my 0.6bar setting is now running around 0.7bar. The odd thing is this, my EBC holds boost at 12.5psi from 2600rpm to 4800rpm then the valve timing kicks in and boost immediately (not tales off) drops to around 10psi. So due to this on my first setting and second boost setting I get pretty much the same peak power output. At the end of the day I'm happy, 245hp @ wheels is nice for the basic mods I have done. The next few things will probably be cosmetic or to assist the engine rather than make HP, like a lighter flywheel (as per rev210's success with his lightened flywheel, 0.4seconds off the 1/4 mile is huge) and a oil catch can, was a bit of oil in the intake manifold when steve pulled it off to change the plugs. Then it'll be time to do the ecu plus a new fuel pump or regulator and should be hopefully pushing 300hp and try and fix up this odd boost curve Thanks to steve @ sst for the engine work and dyno

I'm usually up around 7am, I get to work between 8-15 and 8-30 depending on traffic and time I leave. I love my work so much hehe... kidding, its the only way I can find some time to do things without customers.

There is one called engine control, I'd say it'd be that one?

I'm gonna wander off for another drive now its a bit cooler see if the problem subsides or persists.... might just need a long drive to relearn.

Paul, I couldnt leave it off any longer with the siren going hehehe...

yeah could be afm related... if so, all the more reason to **** it off and get the autronics ecu in with a map sensor I'll wait till it cools down a bit and go for a drive again tonight see if its still doing it.

I did disconnect the battery, run into the car press the brake 5 times and then reconnect the battery while the siren was going, so maybe its just trying to relearn the maps or something... *shrug*

Yup and now its doing weird shit again still, it drives better with the HKS on than it does with the hurricane one... *sigh* ah well, I will just limp around in it till monday morning when we fit the other stuff up and dyno it and see if steve knows what we can do.

No I couldnt reset the ecu properly, I dont have that key that shuts the siren off and the pin code is so you can disarm the immobiliser and drive the car... anyway, put the HKS pod back on, but now its doing weird shit at the top end. It sounds like a baffled "pop pop pop" noise and is hesitating (under 100% throttle, if I dont floor it it goes ok) ... it could be leaning out now *sigh* me give up.

later off to see troy and help him with his blitz sbc

I have a heap of dishes that need doing apart from that the house just needs quick vacumm, jarah floorboards are such a pain in the ass to keep clean can always see dust on them. I think my wife malts more hair than the dog sometimes.

probably, thats why the siren is going off still.

hmmm... I think I'll just disconnect the battery, run in the car press the brake pedal a few times and then quickly reconnect the battery while the siren is going. i've done that before

I have no key I have a pin thingy where you let the light flash so many times, but thats to start to car and disable the imobiliser.

Anyone know how to reset the ecu without disconnecting the battery? I have a cyclops p355/375/385 alarm (dunno which one cant find the install invoice for it) and when I disconnect the battery, even after disarming the alarm, it sets the siren off. Anyone have any idea's? If I cant reset the ecu properly the new filter I put on will have to come off till I get a new ecu

Personally I like the blitz sbc unit's. they have the rep as being the best in the business with boost control (blitz that is) plus it reads boost in bar as well so acts like a gauge.

How can I fix it ken?

Ross from works auto put one of those hurricane filters on for me yesterday, they are supposed to be a huge improvement over the HKS pod filter. Driving home tonight I'd put my foot down with 12psi of boost and it'd cut out as soon as it hit 12psi, so I dropped it back down to 9psi and it was misfiring bigtime at the top end and didnt feel like it was pulling past 5000rpm... any idea's? think I'll go back to the HKS pod and get a refund.

When I come in on monday and we fit the front+dump pipe and then dyno it we should look at the original dyno graph with its boost and a/f ratio and see how rich it was running. BTW: steve I got the hurricane filter from works auto as well and thats on, so that should help the AFM read better as you said.

well done adam 346hp would be nasty in this perth weather at the moment hope you have a low boost setting
