Why would you put it in the stock location though, doesn't it need to be 20 inches down the pipe like the innovative ones?

I've got an Innovate Scott, so its going 20 inches down and I'm leaving the stock O2 alone.

So why do you need to plumb the wideband into the fcon if the narrowband is wired in also? Do you want to log the data?

I just drilled a hole big enough for the sensor to slide through in the tunnel and stuck a bung there, that way I didn't have to drag the wire through the engine bay, and also the electronics are nicely tucked under the carpet instead of in the hot engine bay. The innovative units are prone to overheating and failing.

Dale- I love it when you talk dirty to me. Purge, oxidised, argon.... makes me feel more manly saying stuff like that!

Good to hear its back on the road. What boost? I take it same actuator? so 15/16 psi? The response sounds quite nice, and the best you could get to stock by the sounds of it.

Lol! Nipple, ballcock, flange; it's all there... :woot:

Yeah, same actuator; just shimmed it out to get a little more preload. Not the best solution, but it'll do until I can get a Scotty special. I know it's not creeping until 7 psi, but I'm sure there's a gain in response to be had there.

I don't have an external boost gauge, so I don't know exactly what I'm dealing with ATM.

Consider yourself quoted Sir

Lol, yeah; had that coming.... :rolleyes:

If only.

What line are you referring to here Dale? Is it to replace the famous banjo - banjo oil feed line? If so I need some details.

Looking forward to more driving impressions after you've had time behind the wheel (& don't call me up & go "broom broom". lol).

Happy b'day to the young fella too :)

Leon, yes; it is the block to turbo oil feed line. I'll PM you tonight; unless anyone else is particularly interested in detail.

Thanks for the birthday wishes; he was pretty stoked to see the car back on the road too.

I drove it again last night after correcting my metered boost leak. Lets just say it a little different... :banana:

Last night's ambient temp was only 5deg, so that may skew my results a little; but here it is.

I now have 5-7psi at around 2400-2500rpm, all in (lets call it 14-15 psi) at 2800-2900rpm.

Stalled against the brakes it will slowly build to 2500rpm in approx 2-3 sec, then race to 3200rpm as full boost arrives in around a second (ish); release brake, jumps to 3900-4000rpm, spins all four very briefly and it simply f**ks the f**k off. :blink:

I haven't even hand timed yet but there's no question that it is significantly quicker than before.

It will trigger the 100% duty cycle alarm in the Informeter just before the 6500rpm shift point, and it starts all over again.

It doesn't hit the AFM cut, which I'm extremely pleased about; even though it is possibly costing me some flow.

I understand the principle of using a larger intake effectively as additonal plenum area, but what I have now is a pretty nice solution, and is almost completely undetectable to even a educated set of eyes.

I will have to change the way I drive, (with regard to gear selection) but not very much in comparison to the extra performance. I can definitely see how the 3.55 ratio diffs would help here.

Eastern Creek drags in 2 weeks anyone? :whistling:

So why do you need to plumb the wideband into the fcon if the narrowband is wired in also? Do you want to log the data?

Wideband is needed to be plugged into the Fcon for A/F feedback so the V-pro can hit the specified A/F ratios

So what happens when the wideband goes faulty and reads full rich? That's the issue with electronics, they are never reliable enough to trust a tune on their operation imo.

I'm not running the same Innovate unit as you Scotty, i'm running the newer MTX-L, which has the electronics in the gauge, so I'll be able to view the display and correct if necessary.

The funny thing is by the same token the ECU could get corrupted anyway. Any electronics can fail in a standard car, so I don't see much additional risk.

Widebands are not the most stable of gauges, I hope you don't find that out the hard way. The only way I would rely on it for ecu self tuning is to run a pair of sensors with some sort of controller that cut off the feedback if there was a discrepancy between them.

As a gauge for piece of mind, quick road tunes and to back up the dyno wideband data they are great.

Valid point Scott. I would have thought the F-con would have some kind of detection for large variations like that?

I'll bring it up with the tuner. I want it in anyway for the peace of mind and so I can get the fuel pressures right with the FPR. If the tuner thinks it'll be ok, I'll feed it into the F-con. If not, I'll still have the gauge.

After 25 years fixing electronics I have learned it nearly always lets you down, especially in extreme conditions ie. automotive. I try to put as little faith in it as I can get away with. Mechanical solutions are where it's at as long as it doesn't complicate things too much.

But didn't you put your faith in Emanage for a while & now Fcon? Where does that fit in with your electronics theory?

To a certain extent I'm with you, but our cars aren't carby fed pushrod dinosaurs -they're chock full of electronics already. I guess you are talking about using the highest quality electronics...?

When you don't have a choice... Minimising the chance the electronics will fail by padding around the Fcon and keeping the o2 controller in the car will help, even military spec chips have issues over 50 degrees. I need those components but more and more the electronic systems in the car have been whittled away. All the damn sensors and switches nearing the end of their life span, most of which will put the engine in limp mode. I wish I could drop a carby on it. :)

The best mod so far was definitely the map sensor, ditching the afm. It has already saved me being stranded on a few occasions. Manualising the gearbox may be the next endeavour...

Couple of members have requested for the smaller high flow profile for the M35 Stagea working with factory ECU and fuel setup. I've taken few photos and posted below. Compare to the larger profile, this chra has smaller turbine and comp wheel, also run fnt turbine setup, it is expected to produce some where around the 230rwkws mark with supporting mods, should have stock alike response with a much strong top end.

The whole chra is about 15mm shorter then OEM chra, All lines fits fine (oil line needs little bending), the drain pipe flange needs to be slightly skimmed.

Got a stock m35 for test ..... Lol free new turbo! Yay!

Great job Stao, I think you will sell a few of these.

So the rear is only a few MM bigger but the compressor looks to be around 6MM bigger? Should flow well and more responsive than the Sierra stage one's..

Got rid of the old paper job and dropped in a K&N filter yesterday. I'm probably imagining it but it feels a little bit more responsive on the pedal. :woot:

    • 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.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
