Probably not. Says "Owners Manual" not "Service manual". I'd have to have a look at whats in it before I'm prepared to buy one. I'm not sure I even need an owners manual.

Yep, original request to those guys was the full workshop manual back in 2008 (http://www.skylinesaustralia.com/forums/topic/232599-translated-workshop-manual-m35-c34/ )

Also, it states for 2001-2007 Stagea, but no mention of VQ35de? WTF?

I know the answer is here but I can't find it in a rush.

Attessa system fluid - same as the transmission?

Glad I'm not the only one that struggles to find anything.

90 pages of 'info' is more like 'comment on stuff about the M35.'

:rolleyes::ph34r:

To those who've rewired their fuel pump, where did you run the wiring from the battery into the cabin?

I was looking at it today and thinking the easiest way would be to drill a hole in the side of the duct where the cabin air filter is, and put a rubber grommet in. Most obvious place anyway...

Just slide it throug the main wiring grommet, behind the battery, then down the passenger side and along the back seat.

I've got so much stuff going thru there that I've left a permanent draw wire.

Thinking about how I'm getting the Fcon tuned, and more and more I'm thinking I should just go 98 for now. E85 isn't plentiful enough, 98 would just be easier.

If I go that way, I'm already changing the fuel pump and filter, and I've got the wideband.

Would I still need to change the injectors and/or fit a FPR for a 98 tune running the standard turbo?

I can't see you needing bigger injectors with the stock turbo. From what it seems, if you run ~20psi on stock turbo it will die quick ish.

If you tune with the stock boost (allowing extra 1-2psi for exhaust upgrade) it would need the rich factory set AFR leaned out a tad so the injectors should be fine.

As soon as you go the full hog on you intake pipe you will have a top end lean problem with standard injectors & fuel pump. Andy got good results (AFRs richened up nicely) just by changing the fuel pump. My injectors are providing enough fuel just by changing fuel pressure regulator (stock pump). So if you planned to do either of those, & you've already got the pump, then you'll be fine.

I'm of the belief that our standard injectors can be sufficient up to maybe 250kw or more), given a bit of extra pressure to increase the flow. Check out 'injectors online' to see what sizes are used in various factory applications. eg according to that website, Gen III 5.7lt motor uses 260cc, XR6 (including turbo) use 295cc. M35s are 370cc, & when given extra pressure (there's a formula around somewhere) they can flow in the vicinity of 440cc/min.

I would agree with you on the injectors Leon as even at 18PSI with my car my Wideband never gets over 10.8 unless under load going up a hill then is gets to 11.1. However the AFM is well and truly maxed giving readings of 5+...and I know my duty cycle is over 95% at times....I have also seen 100% quite a bit......I can live with that on the street as I am hardly ever up it.

However I would never track it without bigger injectors and the AFM clamped.

P.S. I think its awesome how the car has worked out its tune with the extra pressure at 14v with the Walbro on mine....it would be very interesting to try a set of 440cc injectors in the car with the standard fuel pump to see if/how it runs.

Well that's kind of my plan. Do pump and get tune with MAP sensor.

Will that cause an issue if I do some track work?

    • So recently at the track had experienced a loss of throttle after a period of WOT after installing the emtron ecu, recently did some logging to troubleshoot the issue and found the ECU was cutting due to a low oil pressure issue. Going over the log can see that while accelerating at 4k rpm will see 100 PSI of pressure and holding steady at that level until getting off the throttle which then after can see as low as 25 PSI at 3-4k rpm and will recover back to a normal level after that.   Wondering if anyone has an idea what could be the cause as it just feels abit strange and i dont feel like it could be a sensor issues just due to it clearly sitting at a good pressure until off throttle, in the attached can see a 3rd and 4th gear pull but can even perform great through 3 and 4 gears of WOT but still once off throttle and getting back on it will see pressure drop.
    • There are a few different ways of doing it. I'm currently running two 1000cc pre-TB nozzles and PWM the pump for control. I'll be moving over to a constant pressure system and direct port. I'll run the pump off a regular relay, have it cycle on roughly 5psi before I start injecting to build pressure and then PWM a WMI solenoid (It's basically an injector that can take a lot of pressure and not corrode with water and meth.) The solenoid feeds the 6 direct port ~200cc nozzles. I'll also keep one ~250cc pre-TB nozzle to help keep IAT's in check.  Safety will be a little different as well. I used to use a pressure switch but will be moving over to a pressure sensor between my solenoid and nozzles. I'll trigger my solenoid and if I don't see specific pressure within a specific timeframe (e.g 100psi within a second, 175psi within 2 seconds), I kill it and revert back to non WMI maps the same way I did it before with 4D in Haltech. I was just figuring out the timers in my ecu last night. They made that a little more complicated than I would have liked... I wish Haltech offered a larger set of logic/math functions like other ecu's do. I can't do very much with just AND's and OR's.  I've been asked to do fuel/ignition mapping on a medium bore engine at work in May (192L V16). Being the only programmer in my region and having went and opened my mouth about knowing the ins and outs of fuel/ignition mapping, I have now been deemed an expert. Fun fun. The entirety of the logic and algorithms are programmed in C on a PLC. As I spend more time figuring it all out, I like what I see and eventually I may consider doing the same as a pet project to replace my ecu.   
    • This would be interesting, would you feed it via a 2nd row of injectors? Or just usual WMI nozzles?
    • Cut sump up and extend. Win win 😂
